TS ISO 13616-2

TS ISO 13616-2 is the part of the IBAN standard that defines how IBAN formats are recorded and governed in the registry, and what the Registration Authority (RA) is responsible for. The IBAN is the internationally used account identifier that supports consistent processing of cross-border payments; this part focuses on the registration framework rather than the account number format itself.

The role of the Registration Authority

In the IBAN ecosystem, the RA is the body that maintains the registry of formats conforming to ISO 13616-1 and provides the controlled reference point for those formats. From a general technical perspective, this kind of authority helps keep format definitions consistent, traceable, and usable across payment systems and jurisdictions. That consistency matters because IBANs combine country information with account-specific elements, so the registry has to preserve a clear and unambiguous structure for recognized formats.

Registration procedures and registry structure

According to the scope, this document describes the procedures for registering IBAN formats that conform to the ISO 13616 series and the structure of the registry itself. In practical terms, it provides the governance layer around IBAN format registration: how a format is entered, organized, and maintained as part of the official reference system. This makes the standard relevant to institutions and infrastructures that rely on stable, interoperable IBAN data handling.
