What is a 6 digit bank number?

A 6-digit bank number can refer to several identification elements depending on the context. In the Indian Financial System Code (IFSC), the last six alphanumeric characters identify the specific bank branch. Alternatively, some international banks, like ANZ, use the first six digits of a bank account number (which represent the bank and branch codes) as a National Clearing Code, Routing Number, BSB Number, or Sort Code for receiving money from overseas.
