HMRC EORI Number Check

Validate EORI (Economic Operators Registration and Identification) numbers for UK customs. No authentication required.

What is an EORI Number?

An EORI number is a unique identification number used by customs authorities to track imports and exports. Any business that imports or exports goods to/from the UK needs one.

EORI Number Format

  • GB EORI: Starts with GB followed by 12 digits (e.g. GB123456789000).
  • The 12 digits are typically the company's VAT number (9 digits) followed by 000.
  • Businesses without a UK VAT number get a different format after GB.

When EORI Numbers Are Needed

  • Applying for customs decisions (e.g. binding tariff information)
  • Using customs simplifications (e.g. simplified declarations)
  • Any EU/UK border goods movement since Brexit
