IBAN format

The International Bank Account Number (IBAN) is an internationally agreed system of identifying bank accounts across national borders. The current standard is 13616:2007, which indicates SWIFT as the formal registrar. The IBAN consists of up to 34 alphanumeric characters comprising a country code, two check digits; and the Basic Bank Account Number (BBAN).

Holy See uses IBANs with 27 characters and the following format: IT kk n bbbbb bbbbb aaaaaaaaaaaa (2k, 1n, 5b, 5b, 12a)

• k: Check digits
• n: National checkCharacter (it: CIN)
• b: Bank code (it: ABI)
• b: Branch code (it: CAB)
• a: Account number (it: Numero di conto)

BBAN format

The Basic Bank Account Number (BBAN) format is decided by the national central bank or designated payment authority of each country. It may adopt IBAN without registration. SWIFT also acts as the registration authority for the SWIFT system, which is used by most countries that have not adopted IBAN. A major difference between the two systems is that under SWIFT there is no requirement that BBANs used within a country be of a pre-defined length.

Holy See uses BBANs with max. 23 characters and the following format: a (1a)

• a: Upper case alpha characters (A–Z)
• n: Numeric characters (0–9)
• c: Mixed case alphanumeric characters (a–z, A–Z, 0–9)
