MT760 vs MT799: what is the difference?
By the Vanguard Verify desk · Published 2026-10-23 · Updated 2026-11-02
Short answer: an MT760 is the SWIFT message a bank uses to issue a guarantee or standby letter of credit (SBLC) — it creates a payment undertaking. An MT799 is a free-format message — it carries information only.
| MT760 | MT799 | |
|---|---|---|
| Purpose | Issue a guarantee / SBLC | Free-format bank-to-bank text |
| Creates obligation? | Yes, under its stated rules (e.g. URDG 758 or ISP98) | No, unless the text contains an undertaking |
| Typical use | Payment or performance security in a trade | Pre-advice, readiness confirmation, POF letter |
How to verify either message
- Only banks send and receive them. Confirm through your own bank’s trade-finance desk.
- Check the issuing bank’s BIC, the beneficiary name and the amount.
- Treat any PDF or screenshot as unverified until your bank confirms receipt.
