EORI (Economic Operator Registration and Identification) is a unique number issued by HM Revenue and Customs in the UK and required within the European Community when dealing with Customs authorities for transactions such as Import Customs Clearance.
Without EORI status Customs Clearance cannot be made.
EORI status can be activated for existing VAT registration numbers by completing HMRC form C220
If you are not VAT registered HMRC form C220A must be completed. These are available for download from the HMRC website.
