Introduction

International Banking Account number (IBAN) is an international standard for identifying bank accounts across national borders. It is possible to identify both the country of the bank account and the bank using IBAN.

In Temenos Transact, the IBAN module (IN) –

• Manages the Centralised Reference Data related to IBAN.
• Provides a set of API to access or validate the IBAN-related data against the reference directories, which must be used by all Temenos Business Applications, Country Model Bank layers and local implementations.

Society for Worldwide Interbank Financial Telecommunication (SWIFT) is the formal registrar of IBAN under the current standard ISO 13616-2:2007. The Swift IBAN structure files downloaded from SWIFT are processed and the information is uploaded into relevant tables in Temenos Transact.

The SWIFT regularly releases ‘IBAN Directory Plus’ directory that has the following files:

• The IBAN Structure files – These files contain information related to IBAN formats registered by countries that adopted, or are in the process of adopting IBAN in their payment systems and can be used to validate the format of an IBAN. The file includes information about all SEPA countries as well as non-SEPA countries.
• The IBAN Plus files – These files contain IBAN-related data for financial institutions in SEPA countries and non-SEPA countries that have adopted IBAN and help to derive the BIC from an IBAN.
• The Exclusion List files – These files contain a list of IBAN National IDs that are not allowed in IBANs and can be used to indicate with certainty that the IBAN is not valid. This user guide provides an insight on the setup and usage of IBAN (IN) module. It is relevant to the bank Super-Users and Subject Matter Experts (SMEs) who possess a good knowledge on Retail and Corporate Account Products and Payment Products.

The functional components of the IBAN module supports the following features:

• Generate an IBAN for Temenos Transact accounts.
• Validate a supplied IBAN.
• Return the details of a supplied IBAN.
• Derive BIC code from IBAN.
• Check if IBAN is optional or mandatory for customer payment in a given country.
