Check an EORI Number API

Available in Sandbox Yes
Sandbox base URL
Available in Production Yes
Production base URL


This API enables your application to:

  • check if an EORI number beginning with GB (issued by the UK) is valid.
  • view the name and address of the business that the EORI number is registered to (if the business agreed to share this information).



You can use the sandbox environment to test this API.

In the sandbox environment the last digit of each EORI Number will return each type of CheckResponse:

  • 0 or 1 Vaild with no TraderName or Address
  • 2 to 5 Vaild with TraderName and Address
  • 6 or 7 Vaild with no TraderName or Address
  • 8 or 9 Invalid

Access a set of mock EORI numbers to use when testing in the sandbox environment.



View API endpoints
Why do these endpoints look different?

The endpoints for this API now use the Open API Specification (OAS).

The API has not changed. You do not need to make any updates to your application if you already use this API.
