This page includes a free interactive tool that runs in the browser and sends no data. The figures and rules it uses are the ones stated on this page, with their sources.

## What this tool does, and what it does not

- **It checks the format.** It tests the country code and the length against the rules in the official guidance, and tells you which official service to use next.
- **It does not check registration.** Only the official services can tell you whether a number is registered. Use the [EU validation service](https://ec.europa.eu/taxation_customs/dds2/eos/eori_validation.jsp) for EU numbers and for numbers starting with XI, or the [UK service](https://www.gov.uk/check-eori-number) for numbers starting with GB.
- **It sends nothing.** The check runs in your browser. Nothing you type leaves your device.

## Briefly
- An EORI number identifies an economic operator in customs. It is a **two-letter country code followed by a number** that is unique in that country. The number part can be up to 15 letters or digits ([European Commission](https://taxation-customs.ec.europa.eu/customs/customs-procedures-import-and-export/customs-operations/economic-operators-registration-and-identification-number-eori_en)).
- A person can hold **only one valid EORI number** at a time.
- You get it from **one** customs authority: the national authority of the country where you are established ([European Commission](https://taxation-customs.ec.europa.eu/customs/customs-procedures-import-and-export/customs-operations/economic-operators-registration-and-identification-number-eori_en)).
- UK numbers (GB) and Northern Ireland numbers (XI) are the prefix plus **12 or 15 digits** (HMRC's pattern; its text also says 14 characters, see [sources](https://eorilookup.com/sources/)) ([HMRC pattern](https://design.tax.service.gov.uk/hmrc-design-patterns/eori-numbers/)).

Not customs advice. This site explains published guidance. For your own situation ask your national customs authority or a customs broker.

## The app above

The first tab checks one number or a whole list and tells you which official service confirms each. The second asks four questions to tell you [whether you need an EORI](https://eorilookup.com/eori-need-check/). The third tells you [where to apply](https://eorilookup.com/eori-application-country/), since only one customs authority can assign your number.
