TRN - is a transaction reference number, also called payment reference number or simply sender's refernce. You can find it in a field 20 of MT103 SWIFT form or in any payment confirmation provided by sender's bank.

If that's a SWIFT cross-border payment, also known as international wire transfer, yes, usually you can track it. You either request sender's bank to do it using GPI services, or you can use our basic tracker, provided by TrackMySwift.

Most of the time - yes. However if you can't locate your payment by TRN, ask sender's bank to provide an UETR number. It is usually more reliable.

A Unique End-to-end Transaction Reference (commonly known as a UETR) is a string of 36 unique characters featured in all payment instruction messages carried over Swift. The format of UETR is XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX. Sometimes you can see it in MT103 form, sometimes not. Sender always can ask his bank to provide UETR code of SWIFT transfer.
