Economic Operators Registration and Identification system (EORI)

If you are a trader who imports or exports goods into or out of the European Union (EU), you will need an EORI number. This number is valid throughout the EU. It is used as a common reference number for interactions with the customs authorities in any Member State.

Details on how to register for an EORI number are available in the EORI Registration on ROS guide.


It is mandatory to include the Eircode (postcode) in all EORI registrations (new and existing) to avoid declarations being rejected.

Before applying for an EORI number you need to register for Revenue Online Services (ROS). When registering for ROS include your Eircode in the Eircode field. If you are already EORI registered, please ensure your Eircode is included under your official address on the 'Profile' tab in ROS.

A short eLearning tool for EORI is available to download from the European Commission website.

You can also view this video guide on how to register for EORI.

You may have had your EORI number aligned to your existing Value Added Tax (VAT) number. This was generally done for economic operators that held a customs and excise registration when EORI was introduced in 2009.

You can check if you were automatically registered for EORI by accessing the Economic Operator Identification and Registration system. You should insert your existing VAT number prefixed by 'IE' under 'Validate EORI numbers'.
