IBAN is the international standard for the presentation of an account number. It was created the ISO (International Organization for Standardization) and the ECBS (European Committee for Banking Standards) in order to rationalize cross-border payments. As of 2020, its use in Switzerland will be mandatory.
The presentation of traditional accounts numbers in standardized IBAN format simplifies the recording, transmission and processing of payment data.
IBAN in Switzerland
Since many years, the Swiss financial institutions have been supporting the use of the international standard on credit and debit advices, account statements, payment slips, card products, in direct debit processing or e-banking. They have committed themselves to replace the proprietary bank account numbers by the IBAN standard no later than 2020.
