A bank code is a code assigned by a central bank, a bank supervisory body or a Bankers Association in a country to all its licensed member banks or financial institutions. The rules vary to a great extent between the countries. Also the name of bank codes varies. In some countries the bank codes can be viewed over the internet, but mostly in the local language.

The (national) bank codes differ from the international Bank Identifier Code (BIC/ISO 9362, a normalized code - also known as Business Identifier Code, Bank International Code and SWIFT code). Those countries which use International Bank Account Numbers (IBAN) have mostly integrated the bank code into the prefix of specifying IBAN account numbers. The bank codes also differ from the Bank card code (CSC).

The term "bank code" is sometimes (inappropriately) used by merchants to refer to the Card Security Code printed on the back of a credit card.
