A currency-exchange receipt can become important later when you need to verify the transaction, resolve a discrepancy or document a specific exchange-back scenario before departure.
Quick answer: if a receipt, invoice or transaction record is issued, check it before leaving and keep it until your trip and any exchange-back decision are finished.
Legal-source check: 22 September 2026. Circular 75/2025/TT-NHNN remains in force from 31 December 2025 and includes transaction recording, issuing invoices to customers and retaining documents, invoices and books in the exchange-agent operating procedure.
What to check on the transaction record
- Foreign currency: the currency matches the banknotes you exchanged.
- Foreign amount: the amount matches the cash you handed over.
- Exchange rate: the rate matches the transaction you accepted.
- Fee or adjustment: any separate charge or adjustment is understandable.
- Final VND: the amount shown matches what you actually received.
- Date: the transaction date is correct.
- Provider or transaction point: the record identifies the transaction appropriately.
Count or verify the VND before leaving. A receipt is useful evidence, but a simple counting issue is easier to resolve while you are still at the transaction point.
What to do if the amount or rate looks wrong
- Stop before leaving the counter.
- Compare the foreign amount on the record with the notes you handed over.
- Compare the exchange rate with the rate you accepted.
- Check any separate fee or adjustment.
- Recalculate the expected final VND amount.
- Ask for the discrepancy to be explained and corrected through the transaction process if necessary.
Record-keeping is part of the current exchange-agent framework
Circular 75/2025/TT-NHNN requires the operating procedure in an exchange-agent registration file to cover security, transaction recording, issuing invoices to customers, retaining documents/invoices/books, accounting and reporting. The regulation does not mean every provider uses an identical receipt design.

A receipt can have a specific role before departure
The State Bank of Vietnam’s national risk assessment describes a specific repurchase scenario at exchange agents in international border-gate isolation areas. For an amount above USD 1,000 equivalent in that scenario, the publication describes use of a passport together with a receipt showing the earlier exchange. It also states that the receipt used for that repurchase scenario is valid for 90 days from the date shown.
This is a special border-area scenario. It is not a promise that every town exchange counter can reverse your earlier transaction or sell you foreign currency before departure.

Receipt versus a rate screenshot
A screenshot can show what a website published at one moment. It does not prove which banknotes were accepted, what amount you exchanged, whether an adjustment applied or the final VND you received. Keep the actual transaction record for the completed exchange.
Use the Exchange Rate Timestamp Guide for rate freshness.
Receipt versus a customs declaration
- Customs declaration: records qualifying cash carried across an international border.
- Exchange receipt or invoice: records a foreign-exchange transaction.
If you entered Vietnam with a larger amount of cash, you may need to retain both types of paperwork. See Bringing Cash Into Vietnam.
Keep the receipt for larger exchanges and leftover-VND planning
For a larger exchange, a transaction record gives you a clearer reference for the foreign amount, rate and final VND. If you may have leftover VND near departure, keep the record until you have finished deciding what to do with the remaining cash.
Use Large Currency Exchange in Phu Quoc and Leftover Vietnamese Dong for those workflows.
Receipt checklist before you walk away
- Foreign currency correct

- Separate fee/adjustment understood
- Final VND correct
- Date correct
- Provider or transaction point identifiable
- VND counted or verified
- Record stored separately from cash where practical
Evidence note: this page does not publish a sample receipt as proof because no verified first-party redacted receipt has been supplied for publication. If one is added later, it should be a real anonymized transaction record rather than a mockup presented as evidence.
Freshness note: legal procedures and exchange-back rules can change. Use the current legal database and the actual transaction provider when a receipt has a legal or operational role beyond simple record-keeping.
