What Is an EORI Number and Does Your UK Company Need One?

If your UK company imports goods, exports products overseas or moves certain goods between Great Britain and Northern Ireland, you may need an EORI number. Without the appropriate registration, you could face delays when making customs declarations or arranging international shipments.

An EORI number stands for Economic Operators Registration and Identification number. It is a unique identifier used by customs authorities to identify businesses and other operators involved in activities covered by customs legislation.

Does every UK company need an EORI number? No. You will generally need one if your business imports or exports goods across relevant customs borders, makes certain customs declarations or applies for an export licence. A company that only provides consultancy, software development or other services will not usually need one. This guide explains what an EORI number does, which UK companies need one, the difference between GB and XI EORI numbers, how to apply and what international founders should consider before shipping goods.

What Is an EORI Number?

An EORI number is a unique reference used to identify an economic operator when dealing with customs authorities. In the UK, HM Revenue & Customs (HMRC) manages EORI registration. The number helps customs authorities identify the business or person involved in importing, exporting and other customs-related activities. It may be required when making declarations through systems such as the Customs Declaration Service.

For example, imagine a UK limited company imports electronic components from China to assemble and sell in Britain. The company may need a GB EORI number to complete the relevant import customs procedures. Similarly, a UK business exporting manufactured products to the United States may need an EORI number to make the required export declaration.

An EORI number is not the same as a company registration number or a tax registration number. It identifies an operator for customs purposes rather than replacing the company's existing legal and tax identifiers.

Does Your UK Company Need an EORI Number?

Whether your company needs an EORI number depends mainly on its activities, where it is established and the customs procedures involved. You may need an EORI number if your business moves goods:

• Between Great Britain and a country outside the UK, including EU countries.
• Between Great Britain and Northern Ireland.
• Between Great Britain and the Channel Islands.
• Between Northern Ireland and countries outside the EU.
• Through customs procedures that require an EORI number.
• In connection with an application for an export licence.

The precise requirements depend on the movement and the company's circumstances. Not every shipment requires the same declarations, and certain goods movements have specific arrangements.

Examples of businesses that may need an EORI number

An online retailer importing stock: A UK ecommerce company buying clothing, electronics or homeware from suppliers abroad will generally need to consider EORI registration for commercial imports.

A manufacturer exporting products: A business shipping its own products to overseas customers may need an EORI number to make export declarations.

A wholesaler buying from the EU: A company bringing commercial goods into Great Britain from an EU supplier may need a GB EORI number for the relevant customs procedures.

A business moving goods to Northern Ireland: A company moving goods from Great Britain into Northern Ireland will usually need an EORI number, and may need one beginning with XI depending on the movement and circumstances.

When might your company not need one?

You will not normally need an EORI number if your company only provides services and is not involved in activities covered by customs legislation. For example, a UK consultancy that invoices clients in France, Germany and the United States but does not move goods across customs borders will generally not need an EORI number solely because its clients are overseas. HMRC confirms that most consultancy and service businesses do not need one.

There is also an exception for goods moved solely for personal use where the goods are not controlled. This does not generally exempt commercial imports or exports by a company. The key question is not simply whether your company trades internationally. It is whether its activities involve goods movements or customs procedures that require EORI registration.

What Is the Difference Between a GB EORI and an XI EORI?

The UK has different EORI arrangements for Great Britain and Northern Ireland. Choosing the correct type is important because an EORI issued for one purpose does not automatically cover every customs procedure in another territory A company does not automatically need both numbers. Your requirements depend on where the business is established and the movements or customs procedures it undertakes.

Before applying for an XI EORI, check HMRC's eligibility rules. You must generally have a GB EORI first, and HMRC may ask for evidence of a permanent business establishment in Northern Ireland or other information relevant to your circumstances. If your business operates in both Great Britain and Northern Ireland, review HMRC's specific guidance rather than assuming that one registration covers every activity.

How Do You Apply for a UK EORI Number?

You can apply directly through HMRC's online service. For most eligible businesses, the application is straightforward and does not require paying a government application fee. Start here:

Step 1: Decide which EORI number you need

Most businesses established in Great Britain applying for a UK customs identifier will start with a GB EORI. If your business moves goods to or from Northern Ireland, check whether an XI EORI is also required. Do not apply for an XI number simply because you have a UK company or an overseas customer.

Step 2: Prepare your business details

For a GB EORI application, HMRC says you may need:

• Your company's Unique Taxpayer Reference (UTR).
• Your business start date.
• Your Standard Industrial Classification (SIC) code, available through Companies House for registered companies.
• Your VAT number and effective date of registration, if VAT registered.
• Your National Insurance number if applying as an individual or sole trader.

If your business is not based in the UK, HMRC says you do not need a UTR, SIC code or National Insurance number for the application. Make sure the information is accurate and consistent with your existing records. If you are unsure which details apply to your business, check the instructions within the official application.

Step 3: Complete the online application

Sign in to HMRC's service and follow the instructions. If you do not already have sign-in details, the service allows you to create them. HMRC says you will normally receive a GB EORI immediately unless it needs to carry out additional checks. If checks are required, it can take up to five working days. An XI EORI application can also take up to five working days once the eligibility requirements are met.

Step 4: Keep the number with your customs records

Once issued, store the EORI number securely alongside your company registration details, VAT information and import/export documentation. Give it to your customs agent, freight forwarder or relevant logistics provider when required. Before your first shipment, confirm that the number is valid and that the correct business is named on the customs paperwork.

Does Your Company Need to Be VAT Registered to Get an EORI?

Not necessarily. VAT registration and EORI registration are separate requirements. HMRC asks for a VAT number and effective date of registration if the applicant is VAT registered. This means that a VAT number is relevant to the application where one exists, but it is not a universal prerequisite for every EORI application.

A small company importing goods might need an EORI for customs procedures even if it is not registered for VAT. Whether it must register for VAT depends on its own circumstances and the applicable VAT rules. Equally, having a VAT number does not mean your company automatically has an EORI number. If your business starts importing or exporting goods, check whether a separate EORI application is needed.

Can an Overseas Founder Apply for an EORI for a UK Company?

Yes, a founder can manage a UK company's EORI application from overseas, provided the company and applicant meet the relevant requirements. For a UK-incorporated company, the application is based on the business's details and its customs activities not simply on the director's country of residence. HMRC's application guidance says businesses that are not based in the UK do not need to provide a UTR, SIC code or National Insurance number for the GB EORI application.

Consider a founder living in Nigeria who has incorporated a UK limited company to import fashion products into Britain. If the company will act as the importer and make the relevant customs declarations, it should check whether it needs a GB EORI before its first shipment. The founder should also decide who will handle customs declarations. A freight forwarder or customs agent may be able to assist, but the company must understand which party is acting as the importer, declarant or representative and whose EORI is being used.

HMRC explains that if an operator is not eligible to register for an EORI itself, it may need to appoint someone to handle customs on its behalf. Depending on the arrangement, an indirect representative may be able to facilitate the movement of goods. Do not assume that a UK company formation service automatically includes customs registration. Formation, tax registration and customs compliance are distinct processes.

What Happens If You Import or Export Without an EORI Number?

If your shipment requires an EORI and you do not have the correct one, you may be unable to complete the necessary customs procedures in the expected way. This can delay the clearance or movement of goods and create additional work for your logistics provider.

For a business with time-sensitive inventory, the consequences can extend beyond customs paperwork. A delayed shipment may affect product availability, customer delivery dates, production schedules and cash flow. To reduce the risk:

1. Check EORI requirements before ordering or dispatching goods.
2. Apply early enough to allow for any additional HMRC checks.
3. Confirm whether you need a GB EORI, an XI EORI or another country's EORI.
4. Give your customs agent accurate company and shipment details.
5. Check whether separate import licences, product certificates or customs authorisations are required.

An EORI number does not replace customs declarations, import VAT, Customs Duty, product safety requirements or any licences that apply to particular goods. It is one part of the wider process of moving goods across customs borders.

How Do You Check or Update an Existing EORI Number?

If your company already has an EORI, you should check that it remains appropriate for your activities and that its business details are accurate. HMRC provides separate procedures for changing details or cancelling GB and XI EORI numbers. The process depends partly on whether your business is VAT registered. If a VAT-registered business changes its name, address, trading name or business telephone number, HMRC instructs it to update the EORI record through its VAT online account. Other changes may require a separate form.

You can start with HMRC's official EORI change or cancellation guidance.If your company has stopped importing or exporting, do not assume the EORI must automatically be cancelled. Consider whether the business still needs it for other customs activities, licences or authorisations before taking action.

Frequently Asked Questions

1. Is an EORI number compulsory for every UK limited company?

No. A UK limited company generally needs an EORI if its activities involve relevant customs procedures, such as importing or exporting goods. A business that only provides services will not usually need one.

2. How much does a UK EORI number cost?

Applying for an EORI directly through HMRC's official online service is free. Be cautious of third-party services charging a fee simply to submit the application on your behalf.

3. How long does it take to get a GB EORI number?

HMRC says a GB EORI is normally issued immediately, unless additional checks are needed. If checks are required, it can take up to five working days.

4. Can I get an EORI number without VAT registration?

Yes, where you meet the relevant EORI requirements. HMRC asks for VAT details if you are VAT registered, but VAT registration is not a universal prerequisite for an EORI.

5. What is the difference between a GB EORI and an XI EORI?

A GB EORI begins with GB and is generally used for relevant customs activities in Great Britain. An XI EORI begins with XI and is used for qualifying customs activities involving Northern Ireland. Check HMRC's eligibility rules to establish which number your company needs.

6. Can I use my company's UTR as its EORI number?

No. A UTR identifies a tax record, while an EORI identifies an operator for customs purposes. They are separate references and cannot be substituted for one another.

7. Do I need an EORI to sell products to customers in the EU?

It depends on how the goods move and who is responsible for the customs declarations. If your UK company exports goods from Great Britain to an EU country, it will generally need to consider a GB EORI for the UK export process. The importer may also need an appropriate EORI in the destination country. Confirm the requirements for the particular transaction.

8. Can a customs agent use its own EORI number for my shipment?

The correct arrangement depends on the customs representation and declaration involved. A customs agent may handle declarations on your behalf, but you should confirm whether your business needs its own EORI and which party is acting as the importer or declarant. Do not assume that appointing an agent removes every registration requirement.

9. Do I need an EORI to move goods from Great Britain to Northern Ireland?

You will usually need an EORI for relevant goods movements from Great Britain to Northern Ireland. Whether you need an XI number as well as a GB number depends on your circumstances and the customs procedure being used.

Conclusion

An EORI number is an important customs identifier for UK companies that import or export goods. It is not automatically required by every limited company, but it can be essential when your business makes customs declarations or carries out other activities covered by customs legislation.

Before your first international shipment, establish whether you need a GB EORI, an XI EORI or another registration, and check that the correct business details are used in the application. You can apply directly through HMRC's free online service, with many GB applications completed immediately.

For startups and overseas founders, the practical lesson is simple: arrange customs registration early, understand the responsibilities of your freight forwarder or customs agent, and remember that an EORI is only one part of import and export compliance. Getting these details right before goods move can help avoid unnecessary delays and disruption to your business.
