How to Verify Vietnamese Supplier Bank Accounts: MST, NAPAS
Vietnam gives a payer more than most markets before money moves: the national switch shows the beneficiary's registered name the moment an account number is entered, and every company sits in a free public register alongside its tax status. But two things changed in the last year that most foreign buyers have not caught up with. A new VAT law tightened what a buyer needs to keep the input credit, and the country redrew its entire map of provinces — which means a supplier whose registered address just changed may have done nothing at all. This guide covers the account layer, the company layer, the rule that connects them, and the false positive that will otherwise cost you good suppliers.

The account layer: the name is shown before you send
Vietnam has no IBAN. A domestic account is identified by the bank and an account number whose length varies by institution, so there is nothing to validate structurally. What there is instead is a national real-time switch that surfaces the account holder before a payment is confirmed.
NAPAS 247 is the interbank instant-transfer service run by the National Payment Corporation of Vietnam, connecting the country's banks and payment intermediaries. Its defining feature for a payer is that when a beneficiary account number is entered, the system automatically displays the account holder's registered name for the sender to check before the transfer goes through — without the sender having to type a name at all. NAPAS describes it as checking the beneficiary's card or account information before the transaction. Transfers settle in real time, at any hour, up to just under 500 million dong per transaction.
As in Korea, and unlike European Verification of Payee, what comes back is the name itself. That means the payer does the matching, and can see exactly how the bank-held name differs from the invoice — a transliteration, an abbreviation, a trading name, or a different party altogether. For Vietnamese company names, which are long, often carry a legal-form prefix, and are frequently abbreviated in correspondence, seeing the whole string is worth a great deal more than a match score.
Biometric authentication on transfers
A second control now sits on the sender's side. Under State Bank Decision 2345/QĐ-NHNN, since 1 July 2024 an individual making a transfer above 10 million dong in one transaction, or above 20 million dong in a day, must pass biometric authentication matched against verified identity data, alongside the usual one-time password. The stated aim is to stop transfers from hijacked or borrowed-name accounts. For a buyer it matters in a specific way: the mule accounts that receive redirected supplier payments are harder to open and harder to drain than they were, which shifts fraud effort toward the invoice and the company rather than the account.
The limits
Three caveats. First, access: the name display is a feature of Vietnamese domestic banking channels. A foreign buyer paying by SWIFT from abroad does not see it; the nearest equivalent is the receiving bank's beneficiary-name matching on the inbound wire, which is a settlement control after you have instructed the payment, not a lookup before. If you have a Vietnamese entity or a local payout partner, the display is available through them.
Second, the name is the bank-held name. For a company that is the registered enterprise name as the bank recorded it at account opening — sometimes with the legal-form words spelled out, sometimes abbreviated, sometimes without diacritics. Match against the enterprise name on the registration certificate, and expect cosmetic differences.
Third, a matching name proves the account belongs to the named entity. It does not prove the entity is still trading at its address, that it can lawfully issue you an invoice, or that it is the party that actually supplied the goods. Those are the company-layer questions, and in Vietnam they are the ones with money attached.
A NAPAS 247 transfer is real-time and, once executed, cannot be reversed by the sending bank. Vietnam has no statutory mistaken-remittance recovery scheme of the kind Korea operates; recovery runs through a dispute request to your own bank, which passes it to the receiving bank to approach the recipient, and beyond that through the police or the courts. The name shown before you confirm is the control. Treat it that way.
International payments
An international payment to a Vietnamese supplier is a SWIFT wire to the bank's BIC with the account number and the beneficiary's registered name. The dong is not freely convertible offshore, so cross-border supplier payments are made in US dollars or another major currency, and the receiving bank converts on arrival unless the supplier holds a foreign-currency account. Vietnamese banks apply the beneficiary name to inbound funds and query mismatches, so use the exact enterprise name from the registration certificate rather than an email signature or a shortened trading name.
Where account verification stops, and business verification starts
Paying a supplier safely means answering two questions. Does this account belong to the party I intend to pay? Vietnam answers that well, before you press confirm. Is that party a business I should be paying at all? That is a different question, answered by different tools, and the visible name is where buyers most often stop asking it.
An account match confirms one thing: that the name on the account corresponds to the entity you supplied. It does not tell you the enterprise is still registered, that it is operating at its registered address, that its tax code is active rather than locked, that the invoice it will issue is lawful, or that the person who agreed the contract can bind it. Every one of those is a business-verification question, and in Vietnam every one carries a tax consequence the account check cannot see.
Bank account verification tells you the money will reach the account you were given, in the name you were given. Business verification tells you whether the entity behind that account is registered, active, correctly identified, properly represented, and the real counterparty. Treating the first as a substitute for the second is the single most common gap in supplier onboarding — and in Vietnam it is the gap that turns a valid-looking invoice into a disallowed expense. MonitorPay is designed around closing it: account verification and registry-sourced company intelligence returned together, so the account result and the business result arrive as one answer rather than two workflows.
The company layer: one number does two jobs
Vietnam is unusually tidy here. When an enterprise is registered, the national registration system and the tax registration system jointly generate a single number: the enterprise code, which under Decree 168/2025/NĐ-CP is simultaneously the enterprise's tax code. It is printed on the enterprise registration certificate, used on every invoice and contract, never reissued to another entity, and ceases to be valid when the enterprise ends its activities. There is no separate corporate registration number to reconcile against.
The structure carries a built-in false-positive check. An independent enterprise has a ten-digit code. A branch or representative office has a thirteen-digit code: the parent's ten digits, a hyphen, and a three-digit suffix. So an invoice from a branch will carry a code that differs from the head-office code in your vendor master by its last four characters — and the first ten will be identical. That is the same legal person, not a new counterparty. A thirteen-digit code whose first ten digits do not match anything you hold is a different entity and needs verifying from the start.
The National Business Registration Portal
The National Business Registration Portal is the free public register. Search by enterprise code or name and it returns the enterprise's full Vietnamese name, its foreign-language and abbreviated names where registered, the legal representative, the head-office address, the registered business lines, the date of registration, the enterprise type, and its status. Charter capital appears on the registration certificate and in the register's detailed record.
Two fields deserve attention. The legal representative is the person authorised to bind the company; if the individual signing your contract or emailing bank details is not that person, and holds no evident authority from them, that is a question to settle before payment. And charter capital, which Vietnamese law requires to be declared and paid up, is a free sanity check on scale — an enterprise with twenty million dong of charter capital invoicing you for two billion is not impossible, but it is worth a look.
The tax code status: five states, and two that cost you money
The tax authority's own lookup, free and without login, returns the taxpayer name, head-office address, the tax office that manages the taxpayer, and — the field that matters — the status of the tax code. The states a buyer needs to recognise:
The state that matters most is "taxpayer not operating at the registered address" — the status the tax authority applies after verifying that an enterprise cannot be found where it says it is. When that notice is issued the tax code is locked, and invoices dated after the notice are treated as unlawful. The state just before it, "ceased operations without completing tax code closure", is the absconded-enterprise pattern: trading stopped, obligations abandoned, no proper wind-up. Both are the profile of a company that sold invoices before it disappeared.
A supplier that showed as operating in January and is flagged not-at-address in June has a window in between in which every invoice it issued you may be challenged. The lookup is free and instant. Running it against the invoice date, not the onboarding date, is what shows you were paying an enterprise the tax authority still recognised at the time.
The supplier that is not an enterprise: household businesses
A large share of Vietnam's small suppliers — workshops, traders, transport operators, service providers — are not enterprises at all. They are household businesses (hộ kinh doanh): a registered trading form owned by an individual or a family, with no legal personality separate from its owner, no legal representative, and no charter capital. Everything the previous section says about the enterprise register does not quite apply to them, and buyers who search the National Business Registration Portal for one and find nothing sometimes conclude the supplier does not exist.
It usually does. A household business has a tax code and appears in the tax authority's lookup with its owner's name, its address and its status, and it can be verified there. What it does not have is a separate corporate identity: the owner is personally liable, the "supplier" and the person are the same, and the bank account is often in the owner's personal name rather than a business name — which is exactly what the NAPAS name display will show, and is not a mismatch.
From 1 June 2025, household businesses with annual revenue of one billion dong or more must issue electronic invoices generated from cash registers connected to the tax authority. And from 1 January 2026 the long-standing presumptive lump-sum tax for household businesses was abolished, moving them to declaration on actual revenue and to invoicing. The practical effect for a buyer is that a household supplier is increasingly able to give you a system-registered e-invoice — but the invoice type still matters. Historically a household business issued a sales invoice, not a VAT invoice, and a sales invoice does not carry input VAT you can deduct. Check which one you are being given before assuming a credit.
The verification posture is therefore different, not weaker: identify the household business by tax code, confirm the owner's name matches the account name and the invoice, check the tax code status exactly as for an enterprise, and treat the absence of a legal representative and charter capital as the entity type, not as a gap.
The false positive: Vietnam redrew its map in 2025
This is the paragraph most foreign compliance teams need and few have read. In 2025 Vietnam merged its provincial-level administrative units, reducing sixty-three provinces and cities to thirty-four, and reorganised the district and commune levels beneath them. The practical effect for anyone reading a Vietnamese registered address is that enormous numbers of addresses changed without the business moving an inch. Old province names disappeared, wards were merged and renamed, and registration records were updated to match.
In most markets, a registered-address change shortly before a bank-detail request is a real signal. In Vietnam since mid-2025 it is very often an administrative re-labelling of the same building. Before treating a Vietnamese address change as a flag, check whether the old and new addresses describe the same place under a merged province or renamed ward. The register itself is the source: the enterprise code, the legal representative and the registration date will not have changed, only the address text.
The reverse also applies. Because so many records were updated at once, a supplier that has not updated its address to the new administrative names is not necessarily negligent — the transition is still working through — but a mismatch between the address on a fresh invoice and the address in the register is worth a question.
Why this matters: the VAT credit, and what the 2025 law changed
Vietnam's Law on Value-Added Tax No. 48/2024/QH15 took effect on 1 July 2025, with Decree 181/2025 and Circular 69/2025 the same day. Three of its provisions land directly on how a buyer verifies a supplier.
| Provision | What it requires | What it means for verification |
|---|---|---|
| Non-cash payment | To deduct input VAT, purchases from five million dong upward, VAT-inclusive, must be paid by non-cash means — down from the previous twenty-million threshold. | Almost every B2B invoice now needs a traceable bank payment to a verified account. Cash, or payment routed through an unrelated third party, loses the credit. |
| Lawful invoice | Deduction requires a lawful VAT invoice for the goods or services actually purchased. | An invoice from an enterprise flagged not-at-address, or one that never supplied you, is not lawful support — the credit and the expense fall away. |
| Refund condition | A VAT refund is only available where the seller has declared and paid the VAT on the invoice it issued you. | For refund claimants, your supplier's compliance is now a condition of your own refund — the same inherited exposure as India's Section 16(2)(c). |
The account is part of the tax condition
The non-cash rule is stricter than "pay by bank transfer", and this is where the account layer and the tax layer meet. What Vietnamese VAT practice recognises as valid non-cash payment evidence is a transfer from the buyer's own account to the seller's own account. Cash paid into the seller's account by the buyer does not count. Payment to someone else's account counts only where the contract with the seller specifically provides for payment to that third party.
Follow that through the bank-detail-change scenario. A supplier emails new account details; you pay the genuine invoice to the new account; the account turns out not to belong to the supplier. You have lost the money — and because the payment did not go from your account to the seller's account, and no contract provided for payment to that third party, the payment does not satisfy the non-cash condition for the invoice you actually received. The input VAT on a genuine purchase is not deductible either. Confirming that the account belongs to the seller is not only fraud prevention in Vietnam; it is the evidence your VAT credit rests on.
Two more consequences. If a payment above the threshold was not made by qualifying non-cash means, the buyer is expected to reduce the input VAT it has claimed, and may claim it again once proper payment evidence exists. And using an unlawful invoice — one issued by an enterprise already flagged, or for a supply that did not occur — is an administrative violation by the buyer, penalised under Decree 125/2020, in addition to the lost deduction.
The pattern that connects all of this: the buyer's position depends on the supplier being real, at its address, and compliant — and on the payment being traceable from your account to that supplier's account. Every one of those is checkable before the money moves, and none of them is checked by looking at the account name alone.
Verifying the invoice: the electronic invoice
Electronic invoicing has been mandatory for enterprises in Vietnam since 1 July 2022 under Decree 123/2020, and every valid e-invoice is registered with the tax authority and carries a unique code where the tax authority issues one. The tax authority's e-invoice portal lets a buyer look up an invoice and confirm it exists in the system, was issued by the tax code shown, and has not been cancelled or replaced. For a first invoice from a new supplier, that check — together with the tax code status on the invoice date — is what turns a document into support.
What the account name will not catch
The name displayed by NAPAS before a transfer is a strong control at the moment it runs. It confirms the account exists, can receive funds, and whose registered name is on it — and it lets you do the matching yourself.
It answers nothing about the company — and this is the switch that has to happen in every onboarding, not only Vietnam's. Once the account is confirmed, the question changes from whose account to what business, and the tools change with it. The account can be genuinely in the supplier's registered name while the enterprise is flagged not-at-address, has been suspended, has changed its legal representative last week, or is an invoice-selling shell that will be gone before your VAT return. There are several company red flags a bank account match alone will not catch, and in Vietnam the tax code status is where most of them show first.
When everything matches and it is still fraud
The hardest case is not a mismatch. It is the payment where every check passes — NAPAS shows the right name, the enterprise is on the register, the tax code reads operating, the e-invoice validates — and the money still goes to a fraudster. A company can be entirely genuine and still be a vehicle set up for a handful of transactions before it abandons its address.
Two things follow. The company facts have to be read together — age, address, legal representative, charter capital, filing behaviour — and over time, because a representative, an address and a bank account that all changed in the month before a payment instruction only look wrong against a record of what came before. The free single-purpose lookups each answer one question well; none of them answers the combined one.
The practical test: if a bank-detail change request arrived tomorrow, could you see, in one place, how old the enterprise is, who represents it, what changed recently, and whether its tax code is still clean? If that is four lookups and a spreadsheet, that is the gap this pattern walks through.
One integration, instead of one per country
Vietnam's NAPAS name display answers the account question well. The business question — status, address, representation, ownership — still has to be answered separately, and it shares no format with the next market you pay into.
MonitorPay returns both in one call across 49+ markets — account verification and payee name matching, plus company status, directors, shareholders and ownership from 200+ government registries. Bulk, API or platform. Every check logged. We do not move money.
A practical verification workflow
For a new Vietnamese supplier, or a change to an existing one, a defensible sequence looks like this:
- Request the enterprise registration certificate. Take the exact Vietnamese enterprise name, the enterprise code, the legal representative, the head-office address and the charter capital from it.
- Read the code. Ten digits is the enterprise; thirteen digits with the same first ten is one of its branches, not a new counterparty.
- Establish the entity type first. An enterprise is on the National Business Registration Portal with a legal representative and charter capital; a household business is not, but has a tax code and an owner. Verify each by the route that exists for it.
- Search the National Business Registration Portal. Confirm the name, the legal representative and the status match what you were given.
- Check the tax code status. Operating is the only clean state. Suspended, awaiting verification, ceased-not-closed and not-at-address each mean something specific, and the last two mean invoices will not support a deduction.
- Read address changes with the 2025 mergers in mind. Confirm whether a changed address is a moved company or a renamed ward before treating it as a signal.
- Confirm the account against the enterprise. Where you or your Vietnamese partner pay through domestic channels, the beneficiary name shown before transfer should match the registered enterprise name, allowing for abbreviation and diacritics.
- Then switch questions. Once the account is confirmed, stop asking whose account it is and start asking what business stands behind it. The remaining steps are business verification, and none is answered by the account result.
- Check the e-invoice on the tax authority portal. Confirm it exists, was issued by the tax code you verified, and has not been cancelled or replaced.
- Pay from your own account to the seller's own account. From five million dong, VAT-inclusive, the credit depends on it. No cash deposits, and no third-party account unless the contract names it.
- Re-check the tax code status on the invoice date. An enterprise flagged after onboarding costs you the credit on everything dated after the notice.
- Read the facts together, not one at a time. A young enterprise, a shared address, a newly changed representative and small charter capital are each ordinary alone. In combination, and close together in time, they are the pattern.
- Re-verify on any bank-detail change. The name display makes this fast in Vietnam. Use it every time.
Bulk, API, or the online platform
Three ways in: bulk file checks for onboarding runs and supplier-base reviews, the REST API for verification inside your payment workflow, or the online platform for one-off checks with full audit logs.
Frequently asked questions
How do I verify a Vietnamese supplier's bank account?
Through Vietnamese domestic banking channels, the NAPAS 247 interbank switch automatically displays the beneficiary account holder's registered name when the account number is entered, before the transfer is confirmed. Match that name against the enterprise name on the supplier's registration certificate, allowing for abbreviation and missing diacritics.
Then verify the enterprise: search the National Business Registration Portal for the name, legal representative and status, and check the tax code status on the tax authority's free lookup. A foreign buyer paying by SWIFT does not see the NAPAS name display and relies on the company checks plus the receiving bank's beneficiary-name matching.
Does Vietnam have a payee name check like Confirmation of Payee?
In effect, yes. NAPAS 247, the national real-time interbank transfer service, shows the sender the registered account holder's name for the beneficiary account before the transaction is confirmed — the sender does not type a name; the system displays it. NAPAS describes the feature as checking the beneficiary's card or account information before the transaction.
The difference from Confirmation of Payee is that it returns the name itself rather than a match verdict, so the payer does the matching. The limits are that it is a domestic-channel feature not visible on an inbound SWIFT wire, and that the name shown is the bank-held name, which may be abbreviated or lack diacritics compared with the registered enterprise name.
Is bank account verification enough to onboard a Vietnamese supplier?
No. A matching name on the account confirms the money will reach the entity you were given. It does not tell you the enterprise is operating at its registered address, that its tax code is active rather than locked, that its invoice will support your VAT credit, or that the person who signed can bind it.
Those are business-verification questions, answered by the National Business Registration Portal, the tax code status lookup and the e-invoice portal — and each carries a tax consequence the account check cannot see. Treat account verification and business verification as two separate checks that both have to pass. MonitorPay returns both together, so the switch from one question to the other happens in the same call.
Does Vietnam use IBAN?
No. Vietnamese accounts are identified by the bank and an account number whose length varies by institution, with no checksum to validate offline. An international payment is a SWIFT wire to the bank's BIC with the account number and the beneficiary's registered enterprise name.
The dong is not freely convertible offshore, so cross-border supplier payments are made in US dollars or another major currency and converted by the receiving bank unless the supplier holds a foreign-currency account. Use the exact enterprise name from the registration certificate on the instruction, since Vietnamese banks apply the beneficiary name to inbound funds.
Is the enterprise code the same as the tax code in Vietnam?
Yes. Under Decree 168/2025/NĐ-CP each enterprise is issued a single unique enterprise code which is simultaneously its tax code. It is generated jointly by the national business registration system and the tax registration system, printed on the enterprise registration certificate, never reissued to another entity, and ceases to be valid when the enterprise ends its activities.
The practical benefit for a buyer is that there is one number to verify across the business register, the tax status lookup, the invoice and the payment instruction, rather than two identifiers to reconcile.
Why does my supplier's tax code have 13 digits when the one on file has 10?
Because the invoice came from a branch or representative office. An independent enterprise has a ten-digit code; a dependent unit has the parent's ten digits, a hyphen, and a three-digit suffix — for example 0100109106-015 is a unit of the enterprise 0100109106.
If the first ten digits match the enterprise you onboarded, it is the same legal person invoicing from a different unit, which is normal. If they do not, it is a different entity and needs verifying from the start.
My Vietnamese supplier is not on the National Business Registration Portal. Does it exist?
Probably — it is most likely a household business rather than an enterprise. Household businesses are a registered trading form owned by an individual or family, with no separate legal personality, no legal representative and no charter capital, and they are not enterprises on the national enterprise register. They do have a tax code, and the tax authority's free lookup returns the owner's name, address and status.
Verify a household business by tax code, confirm the owner's name matches the bank account and the invoice — the account is often in the owner's personal name, which is normal — and check the tax code status as you would for an enterprise. Note the invoice type: historically a household business issued a sales invoice rather than a VAT invoice, and a sales invoice carries no input VAT to deduct. The 2025–26 reforms, including mandatory cash-register e-invoices for households above one billion dong of revenue and the abolition of presumptive tax from 1 January 2026, are changing this, so check what you are actually given.
What does the tax code status mean, and which states matter?
The tax authority's free lookup returns the status of a taxpayer's code. Operating is the clean state. Temporarily suspended is a lawful, time-limited pause during which the enterprise should not be issuing invoices. Awaiting verification means the tax office is checking whether the enterprise is at its registered address. Ceased without completing closure is the absconded pattern — trading stopped, obligations abandoned. Not operating at the registered address means the tax authority has verified the enterprise cannot be found where it says it is, and the tax code is locked.
The last two are the ones that reach your books: invoices dated after the notice are treated as unlawful and will not support a deduction or a VAT credit. Check the status on the invoice date, not only at onboarding.
My Vietnamese supplier's registered address changed. Is that a red flag?
In 2025, very often not. Vietnam merged its provincial-level units from sixty-three to thirty-four and reorganised wards and communes beneath them, so a very large number of registered addresses were re-labelled without any business moving. Old province names disappeared and ward names changed, and registration records were updated to match.
Before treating a Vietnamese address change as a signal, check whether the old and new addresses describe the same place under a merged province or renamed ward. The enterprise code, legal representative and registration date will not have changed if it is purely administrative. An address change to a genuinely different location, especially alongside a change of legal representative or bank details, is the pattern worth attention.
Can I lose input VAT because of my Vietnamese supplier?
Yes. Under the Law on Value-Added Tax No. 48/2024/QH15, in force from 1 July 2025, deducting input VAT requires a lawful VAT invoice for goods or services actually purchased, and — for purchases from five million dong upward — a non-cash payment. An invoice from an enterprise the tax authority has flagged as not operating at its registered address, or from a party that did not actually supply you, is not lawful support, and the credit and the related expense fall away.
The 2025 law also made a VAT refund conditional on the seller having declared and paid the VAT on the invoice it issued you — so for refund claimants, the supplier's own compliance is now a condition of the buyer's refund.
What is the non-cash payment rule for VAT deduction?
To deduct input VAT on a purchase of five million dong or more, VAT-inclusive, the buyer must have paid by non-cash means — a traceable bank transfer to the supplier's account, or another form the law recognises. The threshold was twenty million dong under the previous law and was lowered to five million from 1 July 2025.
The consequence is that almost every B2B invoice now needs a traceable payment to a verified account. Cash, or payment routed through an unrelated third party, loses the credit — which is another reason the account and the enterprise need to be tied together before the transfer.
If a supplier's payment was redirected to a fraudster's account, can I still deduct the VAT on the genuine invoice?
Usually not. Vietnamese VAT practice recognises valid non-cash payment evidence as a transfer from the buyer's own account to the seller's own account; payment to a third party's account qualifies only where the contract with the seller specifically provides for it. A payment sent to an account that turns out not to belong to the seller, on the strength of an email, meets neither test.
So the loss is doubled: the money is gone, and the input VAT on the genuine invoice you received is not deductible because the payment condition was not met. That is why confirming the account belongs to the seller — through the NAPAS name display, the registration certificate and the enterprise record — is part of protecting the VAT credit in Vietnam, not only part of preventing fraud.
How do I check that a Vietnamese e-invoice is genuine?
Electronic invoicing has been mandatory for enterprises since 1 July 2022 under Decree 123/2020, and every valid e-invoice is registered with the tax authority. The tax authority's e-invoice portal lets you look up an invoice and confirm that it exists in the system, that it was issued by the tax code shown, and that it has not been cancelled or replaced.
Do it for at least the first invoice from a new supplier, together with the tax code status on the invoice date. An invoice that does not appear in the system, or was issued by a code that was already flagged, is not support for a deduction.
Who is the legal representative, and why does it matter?
The legal representative is the individual authorised by law and the enterprise's charter to bind the company. The National Business Registration Portal shows who it is, free of charge. If the person signing your contract or emailing you new bank details is not the legal representative and holds no evident authority from them, that is a question to settle before payment.
A change of legal representative is also one of the facts to read alongside others. On its own it is routine. Shortly before a bank-detail change, and alongside a recent registration or an address shared with many other entities, it is part of the pattern.
Can a fraudster pass every check — a real account, matching name, and an enterprise that exists?
Yes, and this is the case that gets through. An enterprise can be genuinely registered, hold a real account in its own name, read as operating on the tax lookup, and issue e-invoices that validate — and still exist only to issue a handful of invoices before it abandons its address and the tax code is locked.
What exposes it is not any single check but the combination: how recently the enterprise was registered, whether its address is shared with many other entities, when the legal representative changed and what enterprises sit in their history, how charter capital compares with the invoice value, and what changed in the weeks before the payment instruction. None of the free single-purpose lookups shows that combination; it has to be assembled from registry-sourced company data and, ideally, watched for change after onboarding rather than checked once.
Does a matching account name mean a Vietnamese supplier is legitimate?
No. It is a strong account-layer result — the account exists, can receive funds, and is registered to the entity named. That is close to a complete answer to whether the account is theirs.
It says nothing about whether the enterprise is still operating at its address, whether its tax code is clean, whether it can lawfully issue you an invoice, or whether it is the real supplier behind the goods. Those are the questions that decide your VAT credit in Vietnam, and they are answered on the company layer — the business register, the tax code status and the e-invoice portal.
Can a foreign company use the NAPAS name display?
Not directly from abroad. The name display is a feature of Vietnamese domestic banking channels — bank apps, internet banking and connected payment intermediaries. A foreign buyer paying by SWIFT does not see it.
If you have a Vietnamese subsidiary, a local payout partner or a corporate banking relationship in Vietnam, the display is available through them. If not, your account-side protection is the receiving bank's beneficiary-name matching on the inbound wire, and the weight shifts to the company checks — the business register, the tax code status and the e-invoice portal — all of which are free and open to anyone.
