Flotter - IBAN Validierung

Published January 2025

Plugin details

This plugin adds a workflow to your app that lets you validate IBAN numbers by doing the following:
Convert the IBAN to uppercase and remove any non-alphanumeric characters.

Basic length check: If the cleaned IBAN is longer than 34 characters (the maximum allowed length for an IBAN), it's invalid.

Reformat the IBAN: Rearrange it according to the IBAN validation rules:
Extract country code (first 2 letters), check digits (next 2 digits), and the remaining characters.

Rearrange the IBAN by moving the country code and check digits to the end and converting letters to numbers (A=10, B=11, ..., Z=35).

Modulo 97 check: It uses the modulo97() function to compute the remainder when dividing the reformatted IBAN number by 97. A valid IBAN will leave a remainder of 1.
Returns the final checksum.
If the remainder is 1, the IBAN is valid.
