1. Foreign Exchange Rules: Why Licensed Vietnamese Exporters Use Onshore Corporate Accounts
One of the most reliable safeguards when paying a Vietnamese supplier comes straight from Vietnam's tax and banking regulations. Under the Law on Tax Administration and State Bank of Vietnam (SBV) Circular 06/2019/TT-NHNN, commercial export transactions above VND 20 million (~US$800) must be paid by bank transfer into an onshore corporate foreign-currency account in Vietnam registered under the exact legal company name printed on the supplier's Enterprise Registration Certificate (ERC).
If an email arrives claiming the supplier's Vietcombank, BIDV, or ACB account is 'temporarily under maintenance' and asks you to send USD to a 'partner company in Hong Kong or Singapore,' a 'payment agent,' or a personal bank account, pause the transfer immediately. Offshore payment routing prevents proper Vietnamese export customs and VAT reconciliation—and is almost always a sign of a compromised email thread.
2. Matching the Exact English ERC Name on Beneficiary Accounts
Every Vietnamese ERC lists three official name lines: (1) the Vietnamese legal name, (2) the Foreign/English registered name (for example, PACIFIC MANUFACTURING JOINT STOCK COMPANY), and (3) the registered abbreviated name. Licensed commercial banks in Vietnam open corporate USD and EUR accounts strictly under the exact English name or abbreviated name printed on the ERC. If the beneficiary name on a Proforma Invoice differs even slightly from the ERC, the transfer will either bounce at the receiving bank or route to an unrelated account.
3. Verifying Corporate Digital Signatures (Chứng Thư Số) & Live Callbacks
Every active enterprise in Vietnam uses a government-registered hardware USB Token Digital Signature (Chứng thư số doanh nghiệp) to file taxes, issue electronic VAT invoices, and submit customs declarations. Unlike a pasted image of a red company stamp, a PDF digitally signed with the supplier's corporate token embeds the company's 10-digit Tax ID and tamper-evident timestamp. Buyers should require token-signed bank confirmation letters and complete a brief live phone or video call with the supplier's registered Legal Representative before releasing any wire transfer.

5. Frequently Asked Questions
Q1. A Vietnamese supplier emailed saying their USD bank account changed to Hong Kong or another bank—is this a scam?
Yes—treat any mid-negotiation bank account change (especially to Hong Kong, Singapore, Europe, or a third-party name) as a critical Business Email Compromise (BEC) alert. Under Vietnamese tax and SBV foreign exchange law, legitimate Vietnamese exporters must receive export proceeds into an onshore corporate bank account in Vietnam bearing their exact ERC company name.
Q2. How do I verify a corporate bank account in Vietnam before sending a wire transfer?
First, confirm the SWIFT BIC belongs to a licensed bank branch in Vietnam (country code VN) and the beneficiary name matches the exact English company name on the supplier's ERC. Second, require the Proforma Invoice and bank confirmation letter to be digitally signed with the company's government-registered USB Token (Chứng thư số) embedding their 10-digit Mã số thuế. Third, verify the account out-of-band with the statutory Legal Representative.
Q3. Can Vietnamese banks recover money sent to an unauthorized account?
Once cross-border funds reach an unauthorized beneficiary account, they are typically withdrawn quickly, making post-transfer recall very difficult. Confirming onshore bank account ownership, corporate e-signatures, and phone verification before releasing funds is essential.
