Do you offer a free sort code checker?

We do, see our free sort code checker; in addition all our plans include a number of free sort code and account checks. We carefully curate and update our data weekly to ensure that our customers get the most accurate and up-to-date information available. We also need to run our infrastructure and support systems. Our plans are very competitive, starting from just £96+VAT a month which includes 10,000 free checks. See our plans here.

What types of accounts can you check, and what countries are covered?

We can validate sort codes and account numbers from the United Kingdom and Republic of Ireland. We can also validate IBAN for all participant countries. Some participant countries use a national check digit, and we can validate that too.

We hold data for all UK and Ireland banking institutions, as well as the types of payments they support. We are working towards supporting European and International institutions so that we can offer a global lookup of branch data.

Which plan is right for me?

We offer three plans, designed to suit different needs:

  • Our Enterprise plan is designed for businesses who need a lot of checks each month. We customise each plan based on your requirements. If you think you'll need an SLA or high volume, this is the most cost effective plan for you.
  • Our Professional plan is designed for businesses who need a moderate/high number of checks each month, and we include 25,000 free checks.
  • Our Standard Plus plan is designed for small businesses or individuals who need minimal checks each month, and we include 10,000 free checks.
If your business needs something different, get in touch and we can create a bespoke plan.

How do I use your API?

To use our API you'll need some programming experience, or a team of software engineers within your business. We've made our API as easy to use as possible, and include example code to help you or your engineers get started quickly.

I don't have any programming skills, can I still use Mintly?

Yes! We have a secure portal where you can use our tools to submit sort codes and account numbers, either individually or in bulk, to check if they're valid. These checks come out of your paid plan, and display the account and branch data.

We also have a Zapier integration that allows you to connect Mintly to any other software that Zapier supports. Check out for details!

Where do you get your data from?

We are an Authorised Distributor for the Extended Industry Sort Code Database (EISCD). We get updated data from Vocalink  each week so you can rest assured that you have the most current information available. If you'd like to licence the EISCD data directly, please do get in touch.

We use the latest modulus checking algorithms, the same ones used by banks to generate account numbers.
