UK EORI Number: The VAT Link Founders Miss Before Shipping
Most UK businesses moving goods across the border need a GB EORI number, and the only common exception is the XI prefix, which covers certain Northern Ireland movements. You can apply free on Gov, and in most cases the number is issued immediately; for businesses involved in cross-border trade, exploring effective forex hedging strategies can further help manage currency risk. If HMRC needs extra checks, the wait can stretch to 5 working days.
TL;DR:
Choose the prefix by route: GB covers Great Britain movements with other countries, qualifying Northern Ireland movements require XI, and EU established businesses use their country’s EORI.
GB numbers are usually issued immediately, but checks can take up to 5 working days; XI applications can take the same, so apply before shipping.
EORI and VAT registrations are separate, but deregistering from VAT automatically cancels an EORI tied to that VAT number; apply for a replacement before trading continues.
The GOV.UK application is free and takes about 10 minutes; gather your UTR, SIC code, business details, and VAT number first.
If you cannot hold an EORI, an indirect customs representative can file using its own number, but can share liability for declarations.

What is an EORI number and why does customs use it?
An EORI number is the identifier customs authorities use to recognise you as someone who moves goods. The letters stand for Economic Operators Registration and Identification. Without one, a customs system has no way to match a declaration to your business, so shipments stall.
HMRC guidance describes the system as a customs identification tool, and it is separate from VAT registration. HMRC and GOV.UK are the issuing and authoritative source, so any website charging you for a number is not the official route.
In practice, you will quote your EORI in several places:
Import and export customs declarations, including those made by a freight agent on your behalf.
Export licences and other authorisations that sit in HMRC’s customs systems.
Registration on platforms such as the Customs Declaration Service (CDS), and movement systems such as GVMS where they apply.
Carrier and courier paperwork, where the haulier needs your number to lodge the declaration.
A GB EORI has a simple format: 12 digits preceded by “GB”. If you are VAT registered, the first 9 digits often mirror your VAT number, followed by a block of zeros. That formatting link is where many founders get confused, and we come back to it below.
Who needs an EORI number?
The trigger is what you do, not how big you are. If your business imports goods, exports goods, makes customs declarations or applies for customs decisions, you need the right EORI for your route. This applies to limited companies, sole traders and partnerships alike, as GOV.UK explains.
Typical triggers include:
Buying stock from a supplier outside the UK and bringing it into Great Britain.
Selling physical products to customers overseas, including the EU.
Lodging customs declarations yourself, or asking HMRC for a customs decision.
Holding a customs authorisation or licence.
A pure consultancy or service business that never moves goods covered by customs legislation usually does not need one. Private, non-commercial shipments are also generally exempt: you normally do not need an EORI for non-controlled goods you are moving for personal use only.
HMRC’s registration guidance adds a nuance: an economic operator established in the UK should register for a GB EORI, and in some cases a non-economic operator may be required to register as well. When in doubt, check the guidance for your specific activity.
Pro Tip: If you run an online shop, count the goods that cross a border on your behalf as well as the ones you carry yourself. A dropshipping supplier shipping directly to an EU customer can still put customs formalities on your business.
Which EORI prefix should you use: GB, XI or EU?
The prefix depends on where your goods travel. GOV.UK’s check which EORI number you need page makes the point that you may need more than one, and that if you hold an EORI not starting with GB and move goods to or from Great Britain, you must apply for a GB EORI.
A workable rule of thumb:
GB EORI: movements between Great Britain and any other country, including the EU.
XI EORI: moving goods into Northern Ireland from Great Britain, or from Northern Ireland to non-EU countries, as GOV.UK sets out.
EU EORI: if your business is established in an EU country, you use the EORI issued by that country for Northern Ireland movements rather than an XI number.
Some UK businesses need both GB and XI. You must hold a valid GB EORI before you can apply for an XI one, so the sequence is not optional.
Two quick examples show how this plays out. A bakery in Manchester shipping packaged goods to a retailer in France needs a GB EORI, because the goods leave Great Britain for the EU. A Liverpool wholesaler sending stock to a customer in Belfast needs an XI EORI as well as a GB one, because the goods are moving into Northern Ireland.
For a company established in, say, Ireland that moves goods in and out of Northern Ireland, GOV.UK guidance says to use the EORI from that EU country. You register with that country’s customs authority, then subscribe to HMRC services where you need to use it for UK declarations. The wider Northern Ireland trading guidance explains when a GB EORI continues to apply and when an EU-issued number takes over, depending on the scheme or authorisation in place.
VAT paperwork has its own twist. For Northern Ireland and EU movements under the Windsor Framework, you may need to add an XI prefix to VAT numbers on documentation, and a standard GB VAT number should not be used for those specific transactions, according to HMRC.
How do you apply for a GB or XI EORI, step by step?
Applying is free and done online. The registration guidance says the digital service takes around 10 minutes to complete, so the real work is gathering your details beforehand.
Check whether you already have an EORI. If your business has previously traded in goods, or you are VAT registered, a number may exist, and applying twice causes confusion.
Gather your data: organisation name, address, Unique Taxpayer Reference (UTR), business start date, SIC code, your VAT number if you have one, and your National Insurance number if you are a sole trader. GOV.UK lists the required items on its apply page.
Sign in to the GOV.UK digital service using your Government Gateway credentials, creating them first if you do not have any.
Complete the form and submit it. You receive your GB EORI immediately unless HMRC needs to make checks, in which case it can take up to 5 working days.
If you also move goods into Northern Ireland, apply for the XI EORI once your GB number is in hand. XI applications can take up to 5 working days.
Record the number somewhere your whole team can find it, and give it to your freight agent, courier or customs broker.
Timing: you get a GB EORI immediately in most cases, and up to 5 working days where HMRC needs to run extra checks. Plan shipments around the longer figure if a deadline is close.
The step that trips founders up most is VAT. Being VAT registered does not automatically give you an EORI, and holding an EORI does not make you VAT registered. They are separate registrations that share a number format, so an EORI can exist without a VAT number and the reverse. If you are still deciding whether to register for VAT, our walkthrough on finishing UK VAT registration without HMRC follow up covers the process.
Pro Tip: Apply for your EORI before you need to ship, not the day your first supplier invoice arrives. You generally need the appropriate EORI for customs activities involving goods, and checks can take up to 5 working days.
What if you cannot register? Appoint an indirect customs representative
Some people and entities are not eligible to hold an EORI. HMRC’s guidance is clear that if you are not eligible to register, you must appoint someone to deal with customs on your behalf, and that person needs their own EORI.
Not having an EORI does not stop you trading. GOV.UK confirms that an indirect customs representative can use their own EORI to handle declarations for you. Many businesses use a freight forwarder, courier or customs broker in this role.
If you go this route, agree the practicalities before the first shipment:
Give the representative accurate commercial documents: invoices, packing lists, descriptions of goods and their origin.
Confirm in writing who is responsible for supplying the information and who handles queries from HMRC.
Ask how they account for duty and import VAT, so your bookkeeping can reflect the costs correctly.
Understand that an indirect representative can share liability with you for the declaration, so choose a firm that checks what it files.
How do you find and check your EORI number?
Start with the official channels. HMRC’s guidance says to use the digital registration service or the Customs Declaration Service dashboard to display your number. You cannot retrieve it by signing into a generic HMRC or business tax account, so ignore any advice to do that.
You can also verify numbers, which helps when a supplier or partner gives you theirs:
GB EORI checker: verifies GB-prefixed numbers against HMRC’s database of GB and XI numbers.
EU EORI checker: covers EU-issued numbers and, where permitted, XI numbers, as the same guidance explains.
Checking a counterparty’s number before you trade can help you catch a typo or expired registration before making a declaration.
Pro Tip: Keep a screenshot of the checker result in your supplier file. If a customs query comes up months later, you can show the number was valid when you used it.
How do you report changes or cancel an EORI?
Keeping your details accurate matters as much as registering in the first place. You can report a change, or cancel an EORI, through the GOV.UK change or cancel service. HMRC also warns about unauthorised use of EORI numbers, with details of how to report problems in its other information guidance.
Events that need attention include:
A change of business name, address or legal structure.
A move into or out of VAT registration.
Ceasing to trade in goods, where you want the registration closed.
Suspected misuse of your number by someone else.
The VAT link bites hardest. If you deregister from VAT, the EORI tied to that VAT number is automatically cancelled, and you must apply for a new, non-VAT-related EORI to carry on trading in goods. Miss that, and your next declaration may be rejected, leaving stock sitting at a port while you sort it out.
Out of date details cause similar trouble. A declaration that quotes an old address or a cancelled number can be refused, so treat your EORI record as a live record, reviewed whenever your business changes.
How long does it take, and when should you contact HMRC?
Most GB EORI applications are issued on the spot. Where HMRC needs to run checks, the registration process guidance says it can take up to 5 working days, and XI applications can take the same.
HMRC’s advice: wait at least 5 working days before contacting them about an EORI registration issue.
If your application is delayed or rejected, work through this list:
Wait the full 5 working days before chasing.
Re-read the details you entered: UTR, SIC code and VAT number are the usual culprits.
Use the specific EORI enquiry form on the GOV.UK help page; HMRC typically responds within 5 working days.

Where founders go wrong with EORI
The same three mistakes come up again and again. First, treating EORI and VAT as one registration. They share a number format, but one does not create the other, and a business can need an EORI long before it needs to charge VAT. Second, choosing the wrong prefix: a GB number does not cover the Northern Ireland movements that need an XI one. Third, forgetting that a VAT de-registration quietly cancels a VAT-linked EORI.
Our view is that an adviser belongs in the conversation early, before the first shipment rather than after the first problem. The EORI is a one-off form, but import VAT is an accounting question: how it is declared, how it is recovered and where it sits in your books. Getting that wrong costs more than the form ever will.
Good oversight also reduces friction. When registration data, VAT status and shipping records all agree, HMRC has little to query, and goods keep moving. Most delays we see come from mismatched details, not from anything exotic.

FAQ
Can I import without an EORI number?
Not as a business making your own customs declarations. You need a GB EORI to import goods into England, Wales or Scotland. The alternative is to appoint an indirect customs representative who uses their own EORI to file for you.
How do I apply for an EORI number in the UK?
Use the free GOV.UK digital service, signing in with your Government Gateway details and entering your business information, including your UTR and SIC code. The number is usually issued immediately, or within 5 working days if HMRC runs checks, as GOV.UK states.
How do I find out what my EORI number is?
Display it through the HMRC digital registration service or the Customs Declaration Service dashboard. HMRC advises that you cannot find it by signing into a generic HMRC or business tax account.
Is an EORI number the same as a VAT number?
No. They are separate registrations that share a number format, and you can hold an EORI without being VAT registered, according to HMRC’s introduction. If you do hold a VAT number, the first 9 digits of your GB EORI often mirror it.
Do I need both a GB and an XI EORI?
Only if you also move goods into Northern Ireland from Great Britain, or from Northern Ireland to non-EU countries. You must hold a GB EORI before applying for an XI one. Businesses established in an EU country use their EU EORI instead.
