How to Use

  1. Step 1: Enter or paste the IBAN number.
  2. Step 2: The tool instantly validates the format and checksum.

Frequently Asked Questions

What is an IBAN?

IBAN (International Bank Account Number) is an internationally agreed standard for identifying bank accounts.

How long is an IBAN?

IBAN length varies by country from 15 (Norway) to 34 characters. It always starts with a 2-letter country code and 2 check digits.

How does IBAN validation work?

IBAN uses MOD-97: move the first 4 chars to the end, replace letters with numbers (A=10...Z=35), compute modulo 97. If remainder equals 1, the IBAN is valid. The tool also checks country-specific format and length per ISO 13616.

What is the difference between IBAN validation and a SWIFT/BIC code?

An IBAN (International Bank Account Number) identifies a specific bank account and is used to designate the recipient account in international transfers. A SWIFT/BIC code (8-11 characters) identifies the bank institution itself and routes the transfer to the correct bank. International wire transfers typically require both an IBAN (account) and a BIC (bank). Within the Eurozone, SEPA transfers only require an IBAN.
