IBAN (International Bank Account Number)

The IBAN is a nationally and internationally valid account number format. With IBAN, payments can be automated and therefore settled faster and more cost-effectively.


IBAN in domestic and international payments

The Swiss banks are continually changing their account numbers over to the IBAN so as to replace the current unstructured account numbers. PostFinance supports the use of the IBAN and recommends that its customers also use the IBAN in future.


  • If you send invoices abroad, please always indicate the IBAN of your postal account number and the BIC of PostFinance (POFICHBEXXX). Credits from abroad will then be transferred both more quickly and more cost-efficiently to your postal account in Switzerland
  • If you have to make payments abroad, you must indicate both the IBAN and the BIC of the bank managing the account
  • In Switzerland it is enough to state the IBAN and/or the postal account number for processing payments

What are the IBAN and the BIC?

  • IBAN stands for International Bank Account Number and is the international standard for presenting account numbers
  • BIC stands for Bank Identifier Code and is used to clearly identify the recipient bank

Where do I find the IBAN and the BIC?

The payment recipient can provide you with details of his account number (IBAN) and his bank (BIC).

What is the IBAN for my postal account?

You can find the IBAN for your postal account on the account statement and in e-finance. You can also use the IBAN calculator for postal account numbers.

How is an IBAN structured?

The IBAN for an account in Switzerland always begins with CH and has 21 digits.

Example of an IBAN for postal account 25-9779-8

CH= country code for Switzerland
63= check digit (individual for each account)
09000= identification of financial institution (clearing number)
000250097798= Postal account no. 25-9779-8

= CH6309000000250097798
