UK sortcodes and account numbers as a serviceessential for BACS and automated direct debits

Validating bank details is a pre-requisite of BACS and Automated Direct Debit processing. Getting it right at source means you will not face the hastle and expense of processing rejected payments, and ensures the transfer of funds.

As well as Sortcode lookup, our service performs bank account modulus checking. Modulus checking allows payment originators to confirm whether the sorting code and account number given by customers are compatible. Performing modulus checks promotes efficiency and improves cashflow by reducing the risk of receiving returned payments.

Research by VocaLink data analysts revealed 55 changes and updates to database information for banks and building societies per week, and more than 200 changes a month.

We take the pain of updates away from you by offering you a web service to supply this validation. Based on the Extended Industry Sort Code (EISCD) database, we host the service, and we process the updates as they are made available every week.
