Check whether a Iceland IBAN is valid — country, length and mod-97 checksum — and break out the bank details. Instant and free, right in your browser.
| Country | Iceland (IS) |
| IBAN length | 26 characters |
| Structure | IS + 2 check digits + 22-character BBAN |
| Valid example | IS12 7654 3210 9876 5432 1098 76 |
Every Iceland IBAN starts with IS and is 26 characters long. The two digits after the country code are a checksum (ISO 7064 mod-97) computed from the rest of the number, so a single mistyped character makes the whole IBAN invalid — which is exactly what this validator catches before a payment is sent.
A Iceland IBAN is exactly 26 characters long, beginning with the country code IS followed by two check digits and the national bank account number (BBAN).
A correctly-formed example is IS12 7654 3210 9876 5432 1098 76. The two digits after IS are a mod-97 checksum that must match the rest of the number.
By confirming it is 26 characters, starts with IS, and passes the ISO 7064 mod-97 checksum. The tool above does all three instantly, in your browser — no data is sent anywhere.
