The UK Customs has changed the way to apply for EORI numbers in the UK. They are no longer accepting any more emailed C220 application forms and it all applications now have to be submitted through an online form @ www.hmrc.gov.uk. This applies to both non-VAT and VAT registered applicants.
If you are already vat registered in the UK you can check if your VAT number is set up as an EORI by adding ‘000’ to the end of it and then entering it in the EORI checker at this address by clicking here: EU EORI Validation Checker (takes you off this site to the EU site). If it confirms valid then you do not need to do anything further.
If it says invald then you need to apply to have your VAT number registered as an EORI by filling in the form at this addess on the HM Customs site: EORI VAT Registered in the UK
