Bank Code
Czech banks are identified by a 4-digit bank code assigned by the Czech National Bank (ČNB). These codes are paired with the account number to form the full domestic account identifier, and are also embedded in Czech IBANs for SEPA payments.

How BC works
The 4-digit bank code identifies the institution and is written after the account number separated by a slash (e.g. 123456789/0800). CERTIS (Czech Express Real Time Interbank Gross Settlement System) handles all interbank payments in CZK.
Where to find yours
After the slash in your account number, in your online banking app, on your bank statement, or embedded in your IBAN.
