| 53 | * International Bank Account Number. |
| 54 | * <p>The IBAN structure is defined in ISO 13616-1 and consists of a two-letter ISO 3166-1 country code, followed by two |
| 55 | * check digits and up to thirty alphanumeric characters for a BBAN (Basic Bank Account Number) which has a fixed length |
| 56 | * per country and, included within it, a bank identifier with a fixed position and a fixed length per country. The |
| 57 | * check digits are calculated based on the scheme defined in ISO/IEC 7064 (MOD97-10). The Society for Worldwide |
| 58 | * Interbank Financial Telecommunication SCRL, SWIFT, has been designated by the ISO Technical Management Board to act |
| 59 | * as the Registration Authority for ISO 13616. Nationally-agreed, ISO 13616-compliant IBAN formats are submitted to the |
| 60 | * registration authority exclusively by the National Standards Body or the National Central Bank of the country. For |
| 61 | * further information see the <a href="../../../doc-files/IBAN-Registry_Release-50_September-2014.pdf">IBAN REGISTRY</a>. |
