How to use this IBAN validator

  1. Paste an IBAN, with or without spaces.
  2. See instantly whether it's valid, its country, and a neatly formatted version.
  3. Use this before sending an international wire transfer to catch typos early.

How is validity checked?

IBANs use a checksum based on the MOD-97 algorithm (ISO 7064): the country code and check digits are moved to the end, letters are converted to numbers, and the result must be divisible by 97 with no remainder.

Does a valid IBAN guarantee the account exists?

No — this only checks the mathematical checksum and format, confirming the IBAN is well-formed. It doesn't verify that the account is real, open, or belongs to a specific person.

Do all countries use IBANs?

No, IBAN is mainly used in Europe and has been adopted by many countries worldwide, but some major economies (like the US) use different account/routing number systems instead.
