The IBAN (International Bank Account Number) is a standardized international bank account identifier. It consists of a country code, a check digit, and a national account structure.
The exact length and structure of an IBAN varies by country. For example, a German IBAN has 22 characters, while other countries may use shorter or longer formats.
These differences are especially important when validating payment data and processing international transfers.
Each country has its own banking and account structures, which are incorporated into the IBAN. These may include bank codes, branch identifiers, or account numbers.
The IBAN standard ensures that these different systems can be used globally in a consistent way, while still preserving national specifics.
That is why it is important to always validate IBANs based on country-specific rules.
