IBAN + BIC Validator

Cross validation

Validate an IBAN and BIC as a pair. Checks individual formats and verifies that both country codes match — a common source of payment rejections.

IBAN

BIC / SWIFT

Try an example:

Enter both IBAN and BIC, then click "Validate pair"

Why this matters

A valid IBAN and a valid BIC can still be incompatible. Sending a German IBAN (DE) with a Dutch BIC (NL) will result in a payment rejection. This tool catches that mismatch before it reaches the payment rail.
