Individual Accounts in Core Banking System

The customer information of the bank is stored in the central server and the individual customer records will have to be selected for effecting afinancial or non-financial transaction or inquiry. In order to identify thespecific customer accounts, branch code and product code are generally prefixed to the account number.

Thus under CBS, in a 16 digit account numbering pattern, a savings bank account bearing its ID number as 4377 in a manual or TBA environment is identified as 0001-012-000004377.

Here the first 4 digits represent the branch code, next 3 digits represent the product/service code (SB A/c) and the remaining 9 digits represent the account number. This is the reason for an increase in the number of digits of the customer account number, when the branch migrates into CBS.

This numbering pattern identifies the SB Account 4377 of branch A from that of branch B.
