Bank Verification

Accurate bank details are essential for successful payments, but mistakes can happen during entry. Bank validation helps minimise errors, fraud, and transaction failures, ensuring compliance with financial standards. Fast, accurate entry of bank account data streamlines checkouts, payments, and Direct Debit setup, enhancing customer service and payment processes.

AFD’s Bank Verification solution provides three use cases: 

1. Confirmation of Payee (CoP) and Payer Name Verification (PNV) provides a live check with the bank that the name, account number and sort code provided matches the account itself. Read more here.

2. Bank Account Validation validates payment details by checking the provided account number and sort codes format, length and modulus check. Bank address can also be returned from the sort code.  

3. International Bank Account Number (IBAN) Validation confirms the IBAN provided meets the correct standard, country code, length and format for all 116 countries.”

RSPB Logo
We rely on AFD’s Bank Verification solution online as part of the new member onboarding process and in the data import function for our main CRM system. We have to ensure that our systems are not a cause of failure when an individual is completing a membership application. To facilitate this, our systems have been designed to make that initial joining experience as smooth and pain-free as possible. Introducing an error is very easy to do, especially when reading an account number and sort code from a card and typing them in. When bank details are entered incorrectly or the account being used does not allow direct debits, a popup message appears notifying the prospective supporter that the entered combination of sort code and account number is invalid.

Validation

ISO 20022 Ready
Bank Validation

With ISO 20022 driving the move to structured address data from November 2026, where bank location information is available, BankFinder returns address components, including Town Name, in separate fields. This can support structured and hybrid ISO 20022 payment data requirements reducing manual data entry, and streamline payment processing. Combined with sort code, account number and IBAN validation, BankFinder provides a simple API-based solution for validating bank details and returning bank address data at the point of capture.

Confirmation of Payee (CoP)

AFD’s Confirmation of Payee solution allows account name, number and sort code to be checked against the data held at that account’s bank or building society.  

This solution is ready to help any organisation wanting to strengthen their payment accuracy processes by providing greater assurance that payments are being sent to the intended recipient and helps prevent fraudsters from impersonating legitimate businesses or individuals.

Bank Account Validation

Helps ensure your payments and Direct Debits go through smoothly by validating sort code and account number combinations instantly.  

Avoid the hassle and expense of chasing up failed payments and meet BACS validation requirements for processing Direct Debits correctly from the start. 

International Bank Account Number (IBAN) Validation

IBAN checksum validation ensures IBAN accuracy and reduces errors in international payments. By catching incorrect IBANs early, failed transactions and costly manual work identifying the errors can be avoided.
