Why this page exists 

Fraudsters routinely circulate letters, guarantees and payment instruments bearing our name. Some are crude. Some are excellent copies of the real thing, down to a genuine reference number lifted from an authentic letter. This is why we do not ask you to trust a stamp, a signature or a letterhead. We ask you to check the document itself, against our register, on our systems. 

How it works

Since July 2026, every outbound IFB document ends with a Document Verification Certificate: a final page carrying a QR code and a 32-character cryptographic reference. To verify, upload the PDF exactly as you received it. The system checks three things in sequence: whether your file is byte-for-byte the original we issued, whether its reference exists in our register, and whether the contents - addressee, date, amount - match what we recorded at issuance.

Older or printed documents can be checked by typing the reference. A valid reference alone is deliberately not a green light: it proves the number is real, not that your paper is. For full assurance, upload the file.

What the results means

• Verified Original - the file is identical to the document we issued. Nothing has been changed.

• Forgery Suspected - the reference is real, but the contents do not match our register. Someone has reused a genuine reference on an altered or fabricated document.

• Not Found - the reference does not exist. The document was not issued by us.

The one rule that matters

Never rely on a link, address or QR code printed on a document you were sent. A forger controls everything on a forged page, including where it tells you to “verify”. Type www.if-bank.com into your browser yourself and start from here. Documents that fail verification are retained by the bank and analysed as evidence of fraud.
