EORI registration: GB, EU & XI numbers

No EORI, no border crossing. flexfrontier obtains your GB, EU and XI EORI numbers quickly and correctly — and makes sure they are linked to the VAT and customs arrangements your shipments depend on.

What is an EORI number?

The Economic Operators Registration and Identification (EORI) number is the identifier customs authorities use to recognise your business. Every customs declaration in the UK and the EU must carry one — for the importer, the exporter, and the declarant. Without a valid EORI, carriers will not accept your freight for customs-controlled movements, declarations cannot be filed, and goods stop at the border. It is the single most common missing piece on a first international shipment.

Three variants matter for UK–EU trade, and Brexit made them non-interchangeable: a GB EORI issued by HMRC for imports into and exports from the United Kingdom; an EU EORI issued by any one member state and valid for customs purposes across all 27; and an XI EORI for businesses moving goods under the Northern Ireland arrangements of the Windsor Framework. A GB number is not valid in the EU, and an EU number is not valid in the United Kingdom — most businesses trading both markets need both.

Which EORI numbers do you need?

You are… You need
Importing into the United Kingdom A GB EORI, issued by HMRC and linked to your UK VAT registration where you have one.
Importing into any EU member state An EU EORI from one member state — normally the state where you first lodge a declaration — valid across the whole Union.
Trading with or through Northern Ireland An XI EORI in addition to your GB number, subject to the Windsor Framework eligibility rules.
Trading both GB and EU Both a GB and an EU EORI — one does not substitute for the other since Brexit.

The rule inside each territory is one EORI per legal entity: an EU EORI issued in the Netherlands works for a declaration in Spain, and branches do not get their own numbers. Applying twice — a surprisingly common mistake — creates duplicate records that later block declarations.

Can a non-established business get an EORI?

Yes — and it usually must. Non-UK businesses can obtain a GB EORI from HMRC, and non-EU businesses can obtain an EU EORI from the member state where they first need to be identified. But an EORI alone does not make you an eligible importer: EU law still requires the declarant to be established in the Union, and the UK applies the same principle. In practice a non-established trader needs its own EORI and an indirect customs representative — both are named on the declaration. We arrange the two together so neither blocks the other.

EORI ≠ VAT number: the EORI identifies you to customs; the VAT number handles tax. They are linked — HMRC ties Postponed VAT Accounting to the VAT registration behind your GB EORI — but one does not create the other. We sequence VAT registration and EORI as a single workstream.

What we handle

  • Scoping — determining exactly which numbers (GB, EU, XI) your flows require, and in which member state the EU application should be made.
  • Applications — prepared and filed with HMRC and the relevant EU customs authority, with establishment and identity documents presented the way each authority expects.
  • Linking — connecting EORIs to VAT registrations, deferment accounts and representation arrangements so declarations actually work.
  • Verification — confirming numbers are live on the EU EOS database and HMRC systems before your first shipment moves.
  • Fixes — resolving duplicate registrations, lapsed numbers and mismatched company details that stall clearances.

EORI registration pricing

Our EORI service is a fixed fee per application, covering preparation, filing, correspondence with the authority and verification that the number is live before your shipment moves — and EORI work is included at no extra cost inside our IOR and representation onboarding. Processing times vary by authority and case: allow one to two weeks as a working assumption, and sometimes longer where establishment documents need review, so it pays to apply well before your first shipment. Quotations are issued the same day.

Common questions
EORI numbers — FAQs
  • What is an EORI number and why do I need one?

    +

    The Economic Operators Registration and Identification number identifies your business to customs authorities. Every UK and EU customs declaration requires one for the parties named on it — without a valid EORI, declarations cannot be filed and goods will not cross the border.

  • What is the difference between a GB EORI and an EU EORI?

    +

    A GB EORI is issued by HMRC and covers imports into and exports from the United Kingdom; an EU EORI is issued by one member state and is valid for customs purposes across all 27. Since Brexit they are not interchangeable — trading both markets requires both numbers.

  • What is an XI EORI number?

    +

    An XI EORI identifies businesses moving goods under the Northern Ireland arrangements of the Windsor Framework. It is held in addition to a GB EORI and is subject to eligibility conditions relating to your operations in Northern Ireland.

  • Can a non-UK or non-EU company get an EORI number?

    +

    Yes. Non-established businesses can obtain a GB EORI from HMRC and an EU EORI from the member state where they first need one. Note that an EORI alone does not make a non-established business an eligible declarant — imports still require an indirect customs representative, which we provide.

  • Do I need an EORI number in every EU country?

    +

    No. One EU EORI, issued by any single member state, is valid for customs purposes across the entire Union. The rule is one EORI per legal entity — duplicate applications in different states create conflicting records that block declarations.

  • How long does it take to get an EORI number?

    +

    Processing times vary by authority and case — allow one to two weeks as a working assumption, and sometimes longer where establishment documents need additional review. We prepare applications completely to avoid resubmission delays and verify the number is live before your shipment moves.

  • How much does an EORI number cost?

    +

    Our EORI registration service is a fixed fee per application, covering preparation, filing, authority correspondence and verification — plus the linkage to VAT and representation arrangements that makes the number usable. EORI work is included at no extra cost within our IOR and representation onboarding.

  • Is an EORI number the same as a VAT number?

    +

    No. The EORI is a customs identifier; the VAT number is a tax registration. They are linked in important ways — UK Postponed VAT Accounting runs through the VAT registration tied to your GB EORI — but each must be obtained separately, and we arrange them together.
