This often led to necessary routing information being missing from payments. The Payments Council has also introduced a best practice recommending businesses and banks refresh their reference data weekly; whilst smaller businesses should ensure their data is updated at the very least on a monthly basis.
For example, sorting code 00-00-00 would represent the main bank office, and the first subbank office registered would have the suffix 01.
Those countries which use International Bank Account Numbers (IBAN) have mostly integrated the bank code into the prefix of specifying IBAN account numbers.
Also the name of such a code varies.
