IBANEndungen

IBANEndungen is a colloquial German term referring to the final digits of an International Bank Account Number (IBAN). An IBAN is a standardized international identifier for bank accounts, used to process domestic and cross-border payments. It combines a country code, check digits, and a Basic Bank Account Number (BBAN). The exact structure of the BBAN depends on the issuing country.

IBAN-Endungen refer specifically to the trailing portion of the BBAN in an IBAN. Because the BBAN encodes the domestic bank and account number, the ending digits vary by country and by individual account. The term is not an official part of the ISO 13616 standard, but is used in practice in German-language contexts to indicate the portion of the IBAN that appears at the end.

Usage and limitations: In some forms and communications, customers are asked for an “IBAN-Endung” as a quick verification, or to share a partial IBAN (for example, the last 4–6 digits) to identify the recipient without exposing the full IBAN. However, the last digits alone usually do not uniquely identify an account and are not sufficient to authorize a payment. For transfers, most systems require the full IBAN (and sometimes the beneficiary’s name or address) as part of the payment instruction.

Security: Sharing only the ending digits reduces data exposure, but care should still be taken, as the end digits may reveal part of the account number. Institutions may have different policies about partial IBAN usage.
