Does the BBAN format follow the format specified for this country?
The Extended Industry Sorting Code Directory (EISCD)
The EISCD is a comprehensive database of payments-related information for financial institutions participating in the UK Payment Schemes: Bacs, CHAPS, Faster Payments and Cheque and Credit Clearing. The simple search facility enables you to check bank sort codes, branch addresses, contact details and BIC codes, as well as identifying which banks and institutions accept faster payments.
The sort code, which is a six-digit number, is usually formatted as three pairs of numbers, for example, 12-34-56. IBAN imposes a flexible but regular format sufficient for account identification and contains validation information to avoid errors of transcription. The ISCD is maintained and supplied by third parties, on behalf of the banking industry, and the copyright is owned by APACS Administration Limited.
