Frequently Asked Questions

How does IBAN MOD 97-10 checksum work? ▾

The first 4 characters are moved to the end, letters are converted to two-digit numbers (A=10 to Z=35), and the resulting large number is divided by 97. If the remainder is 1, the IBAN is mathematically valid.

Which countries use IBAN? ▾

All 27 European Union countries, the UK, UAE, Saudi Arabia, Switzerland, and over 80 countries worldwide use the IBAN standard for cross-border wire transfers.
