Frequently Asked Questions
Common questions about IBAN validation
What is an IBAN?
IBAN stands for International Bank Account Number. It is an internationally agreed system of identifying bank accounts across national borders to facilitate the communication and processing of cross-border transactions with reduced risk of transcription errors.
How many characters should an IBAN have?
IBAN lengths vary by country, ranging from 15 to 34 characters. Each country has a fixed length. For example, German IBANs have 22 characters, French IBANs have 27, and UK IBANs have 22 characters.
What do the first characters of an IBAN represent?
The first two characters represent the country code (e.g., DE for Germany, FR for France). The next two digits are check digits used to validate the IBAN. The remaining characters make up the Basic Bank Account Number (BBAN), which includes the bank code and account number.
