How to find your EORI number
Your EORI number is on almost every customs document your business has received. Start with your paperwork, then ask your carrier, then check the number is still valid before you use it.
1. Look at your customs paperwork
The importer's EORI number appears on:
- import and export declarations your carrier or customs agent made for you;
- duty and import VAT statements;
- carrier invoices for customs clearance.
It's the code starting with two letters, such as GB, XI or an EU country code, followed by digits.
2. Look for the confirmation from when you applied
When an EORI number is issued, the authority confirms it. Search your email for "EORI", and check the inbox of whoever made the application. If an agent applied for you, they'll have it.
3. Work it out from your VAT number
If your business is registered for UK VAT, your GB EORI number is usually GB, then your 9-digit VAT number, then 000. For example, VAT number 123456789 gives GB123456789000.
This isn't always the case, so check the result in our EORI number checker before you use it.
4. Ask your carrier, freight forwarder or accountant
Anyone who has filed a customs declaration for you will have your number on record. Your accountant may have it too.
5. Contact the authority that issued it
For a GB or XI number, contact HMRC's import and export enquiries team or use the EORI enquiry form on GOV.UK. HMRC says the EORI team replies within 5 working days. For an EU number, contact the customs authority of the country that issued it.
Check the number is still valid
Once you've found it, check it in our EORI number checker. If it comes back as not found, it may have been cancelled, and you'll need a new one.
If you can't find a number at all, your business may never have had one. You can apply for a UK EORI number or an EU EORI number.
