RegioBank IBAN Format & BIC Code

RegioBank's BIC is RBRBNL21. Its bank code is RBRB, the code an IBAN at RegioBank carries in positions 5 to 8. Its IBANs are 18 characters long. RegioBank no longer operates independently, so do not use these details for a new payment without confirming them with the beneficiary.

Merged. RegioBank is now part of ASN Bank. de Volksbank brought its three consumer brands together under ASN Bank, and RegioBank made the change on 1 December 2025. RegioBank tells its customers in its own words that they keep their account number and that payment, savings and investment accounts stay as they are for now, so an existing account number should still work.
Announced by RegioBank's own page, which now opens “RegioBank is nu ASN Bank” and its own questions and answers about the change. How we check.
