Validate International Bank Account Numbers via Mod-97 checksum. Country detection for 60+ nations.
The IBAN Validator checks International Bank Account Numbers using the ISO 7064 Mod-97-10 checksum algorithm — the same check used by every European, Middle Eastern, and many other banks worldwide to catch typos in international wire transfers. An IBAN is a 2-letter country code + 2 check digits + a country-specific BBAN (Basic Bank Account Number). The check digits are computed from the rest of the IBAN such that the entire string, when arithmetically rearranged, equals 1 (mod 97).
Formula
Mod-97-10 check (ISO 7064): rearrange IBAN by moving first 4 chars to the end → replace each letter with its digit value (A=10, B=11, …, Z=35) → compute the resulting integer modulo 97. Valid IBAN ⇔ result = 1.Wiring money internationally is one of the few things in modern banking where a single typo can quietly send your PKR 500,000 to a stranger and the bank shrugs because the IBAN passed format checks. That's exactly what the Mod-97 checksum at the front of every IBAN is designed to stop — those two digits in positions 3 and 4 are a mathematical fingerprint of the rest of the number, computed so the whole string equals 1 modulo 97. A single transposed digit on a printed bank statement, a smudged scan, or a copy-paste that dropped a character will fail validation here in milliseconds, before the wire ever leaves your bank. Validates 60+ country formats including Pakistan (PK, 24 chars), UAE (AE, 23 chars), Saudi Arabia (SA, 24 chars), the entire EU, and the UK, with country detection so you don't have to remember which length goes with which prefix. Always validate before you hit submit on an international transfer — the few seconds of paranoia is cheaper than the recovery process if you get it wrong. Banks can sometimes claw back a mistyped wire; often they can't, especially across borders.

The check digits are computed from the rest of the IBAN such that the entire string, when arithmetically rearranged, equals 1 (mod 97). This catches every single-digit typo and the vast majority of digit-transposition errors. Supports 60+ countries including Pakistan (PK), UAE (AE), Saudi Arabia (SA), Germany (DE), UK (GB), and the entire EU.
