What is an MT199 Amendment and when is it used?

An MT199 Amendment is a SWIFT message used for free-format communication between financial institutions, allowing banks to send updates, corrections, or additional instructions related to a previously initiated transaction—typically an MT103 (customer transfer). It does not move funds but is essential for post-payment communication.

This message is commonly used in situations such as resolving discrepancies, or clarifying transaction details. Through an MT199 Amendment, banks can amend information like:

1. Beneficiary name or account number
2. Payment reference or purpose
3. Sender details
4. Value date or currency
5. Instruction or routing errors

It serves as an effective tool for correcting or updating information to ensure smooth and accurate transaction processing.
