When Do I Need an EORI Number and How Can I Get One?

Since the UK left the EU, importing or exporting goods now involves more customs formalities than ever before. One essential requirement for businesses and individuals alike is having an EORI number—short for Economic Operators Registration and Identification number.

If you’ve ever asked, “When do I need an EORI number and how can I get one?”, you’re not alone. Whether you’re an established trader or just sending occasional shipments abroad, understanding the EORI process can help you avoid costly delays at customs.

This blog will guide you through everything you need to know—from who needs an EORI number, how to check if you already have one using the EORI checker UK, and how to get an EORI number quickly.

What is an EORI number used for?

An EORI number is a unique identification code used by UK customs authorities to track businesses and individuals involved in international trade. It helps streamline import and export declarations and ensures your goods are cleared without unnecessary delays.

Whether you’re moving goods through sea freight, air cargo, or courier services, having an EORI number UK is essential for smooth customs processing. It’s recognised across Europe and globally, making your trade activity identifiable and compliant.

Think of it as your customs passport—without it, your goods might get stuck at the border.

Who needs an EORI number?

If you’re a UK-based business involved in importing or exporting goods, you’ll need an EORI number. This applies whether you trade with EU countries or the rest of the world.

Even if you only import occasionally or ship small volumes, HMRC still requires this registration for customs clearance. It’s also essential if you use freight agents or are VAT registered.

From ecommerce sellers to traditional wholesalers, having an EORI number UK is non-negotiable for international trade.

When Exactly Do You Need an EORI Number?

An EORI number becomes mandatory in these situations:

  • Importing goods into the UK from abroad
  • Exporting products to overseas customers
  • Using a freight or customs agent on your behalf
  • Declaring goods through CHIEF or CDS systems
  • Participating in Amazon FBA or other ecommerce exports

If you’re not sure whether it applies to you, use an EORI number check to confirm before shipping. It’s better to be safe than face costly delays.

How to Check if You Already Have an EORI Number

Not sure if you already have an EORI number? It’s quick to check.
  1. Visit the official EORI checker UK page.
  2. Enter your VAT number (if applicable).
  3. The system will show if your EORI is active and valid.
If nothing comes up, it’s likely you need to get an EORI number before importing or exporting goods.

How do I apply for an EORI number in the UK?

Applying for an EORI number UK is simple and free. Just follow these steps:
  1. Visit gov.uk/eori
  2. Sign in with your Government Gateway ID
  3. Provide business details (name, address, VAT info)
  4. Submit the form and wait for confirmation
If you’re not VAT registered, you’ll still need to apply—but with a few extra details like your business activity and trading partners.

Can you ship without an EORI number?

No, you cannot legally import or export goods without an EORI number. If you attempt to ship without one, your goods will be held at customs and won’t be cleared for delivery. This can cause serious delays, additional storage fees, and even missed delivery deadlines. Whether you’re a business or a private individual, HMRC requires that you have an active EORI before any cross-border shipment takes place.

How long does it take to get an EORI number?

In most cases, you’ll receive your EORI number UK immediately after submitting a complete application online. However, if HMRC needs to carry out further checks, it can take up to five working days. The processing time may also vary depending on whether you’re VAT registered or importing via air freight. To avoid delays, double-check your details before submitting.
