Identifying fraudulent transactions

Swift is aware that scammers fabricate fictious payment confirmations, letters of credit or other financial documentation to mislead and defraud their victims.

In some of these scams fraudsters encourage corporates and banks to partner with them based on forged documents, including transcripts or prints of messages purporting tohave been transferred over Swift. We have seen scammers attach such forged message scans or materials as PDFs to their emails, or insert them into other documents. Swift presents examples of such fraudulent materials in the Swift ISAC Bulletins 10105 and 10111.

In other cases, we have seen authentic messages being misused or misrepresented to further scammers’ fraudulent aims. Swift describes fraudulent patterns in a number of Swift ISAC Bulletins, amongst which Bulletin 10133 (“Trade Finance Trickery”).

If you have any doubts about a transcript or print of a message (allegedly) sent over Swift, we recommend that you consult the financial institutions identified as sender or receiver of that message or otherwise referred to in the transaction. Financial institutions connected to Swift are able to confirm whether they sent or received a specific message over Swift and, more generally, can advise about the nature of transactions.

If the financial institution is identified by their Business Identifier Code (BIC), you may consult the Online BIC Directory ( to identify the financial institution concerned.

Swift customers shall contact Customer Support in case of a (suspected) forged Swift message or, more generally, in case of doubt about any documentation allegedly issued by Swift.
