One such API is the AbstractAPI Free IBAN Validator API. Some APIs will also allow you to convert IBAN numbers. Rather than rolling your own, it’s usually recommended to use a package like the NPM iban Javascript library or to rely on a third-party API that handles validation of IBANs. However, it’s a cumbersome process and one that is prone to errors. All of the components and standardizations are available online. You could write your own algorithm to do this process. If the remainder is 1, then the IBAN is valid. Finally, the resulting number is divided by 97, and the remainder is found.The alphabetic characters are converted to their numeric representations, using a standardized conversion method.Next, the first four digits (the country identifier and checksum) are moved to the right-hand side.First, the IBAN number is stripped of all non-alphanumeric characters (spaces, dashes, etc.).

If the remainder of the operation is 1, then the IBAN number is assumed to be valid. The MOD97 algorithm uses the modulus operator to find the remainder of the numeric value of an IBAN number when it is divided by 97. So to represent the above example, we could write The modulus operator is typically represented by the ‘%’ symbol in programming. You will also see it referred to as “modulo.” They are the same thing.Īs an example, when you divide 4 by 2, the remainder is 0. The modulus operation is the process of finding the remainder when one number is divided by another number. If an IBAN number does not pass MOD97 validation, it can be assumed to be invalid. There are several other steps involved in validating IBANs, including validation of the length of the number and whether or not the country identified by the country code can support IBAN, but the MOD97 evaluation is the first and most important step.

MOD stands for “modulus” and it is a mathematical operation. An IBAN (international bank account) number is primarily validated using the MOD97 algorithm.
