🇦🇱 IBAN COUNTRY PROFILE · Albania
An IBAN for Albania always contains 28 characters. After AL and two IBAN check digits, the national BBAN contains 3-character bank identifier, 4-character branch identifier, 16-character account part and 1-character national check digit. No additional bank directory lookup is active for Albania; validation covers the structure and international check digits.
The reference example AL47 2121 1009 0000 0002 3569 8741 shows the country-specific components. It is provided for explanation only and is not a request to make a payment.

The account may be closed or unreachable.
A person or company name is not compared with the IBAN.
A valid IBAN does not guarantee that a payment will be accepted.
Country formats may be updated when the official registry changes.

Bank data validation
For these countries, we check IBANs against available bank directories and return bank details such as institution, city and BIC when available.
IBAN syntax check
Check IBANs for a valid structure, correct length and checksum. This helps you catch typos and transposed digits before a payment fails. Additional bank validation against real bank directories is available for the countries listed above.
