IBAN-ISO20022

IBAN (ISO 20022) is the <IBAN> XML element inside <CshAcct>/<Id>/<IBAN> of the ISO 20022 dictionary that carries an ISO 13616 IBAN.

Definition

The <IBAN> element is the canonical ISO 20022 representation of an IBAN in pacs/pain/camt messages. Its value is validated by regex [A-Z]{2,2}[0-9]{2,2}[a-zA-Z0-9]{1,30}. It is the preferred account-identification mechanism in the SEPA zone and gradually elsewhere.

Origin

Introduced in the first ISO 20022 version (2004). Aligned on ISO 13616 (1997, last revision 2020).

Use

In a pain.001 of a BNP Paribas customer: <DbtrAcct><Id><IBAN>FR7630003000300012345678901</IBAN></Id></DbtrAcct>. Checksum mod-97 validation runs bank-side before execution.
