Reasons why you might need a bank account checker:

Avoid bank fees

Bounced and failed payments mean more cost for your business. Checking account number data in advance saves time and money.

Reduce fraud

By using a sort code checker, you find out the bank branch data and can confirm this with your cusomter to reduce fraud.

Customer satisfaction

When payments work first time, customers are happy and trust your business. If things go wrong it leads to lost customers.

Improve compliance

BACS requires that businesses do what they can to check data before it's submitted. Using Mintly's account checker ensures you're compliant.

Reduce costs

Checking accounts manually is costly and time consuming. Mintly API can check thousands of accounts each second, or upload in bulk and get answers straight away.
