What is an EORI number and why is it needed for imports?

An EORI (Economic Operators Registration and Identification) number is a unique identifier assigned to businesses and individuals who import or export goods between the EU and non-EU countries. As a registered economic operator, you must hold this mandatory identification code to ensure customs clearance, proper tracking of shipments, and efficient international trade. Any business engaging in import or export activities with the EU must obtain an EORI number before shipments can clear customs, as it allows authorities to identify who is responsible for the goods and ensures compliance with customs regulations.

What is an EORI number and why does it matter for imports?

An EORI number is a unique identification code required for all businesses and individuals conducting trade activities with the European Union as a recognised economic operator. Every EORI number begins with a two-letter ISO country code followed by a country-specific unique identifier. The structure follows a consistent EU-wide pattern, though the identifier component differs by country:

Finland: FI + the company’s Finnish Business ID (Y-tunnus), e.g., FI1234567-8. For Finnish companies, the EORI number is directly derived from the Y-tunnus, making it straightforward to identify.
Netherlands: NL + 9-digit tax identification number
UK (post-Brexit): GB + 12-digit number derived from the VAT registration number, e.g., GB123456789000

EORI numbers matter significantly for imports because they serve as the cornerstone of the EU customs system. When importing goods, this customs registration number allows customs authorities to track shipments, process customs declarations, and apply the correct duties and taxes. Without a valid EORI number, goods cannot move through official EU entry points.

The primary purpose of the EORI system is to enhance security measures while streamlining the flow of legitimate trade. It enables efficient risk assessment and helps customs authorities identify potentially problematic shipments while expediting the clearance of compliant cargo. For businesses regularly using forwarding services, having a valid EORI number is foundational to smooth operations.

EU EORI number vs. UK EORI number: what changed after Brexit?

Since the UK’s departure from the European Union on 1 January 2021, EU and UK EORI numbers became two entirely separate systems. An EU EORI number is valid only within EU customs procedures; a UK EORI number is valid only for customs procedures in the United Kingdom. Businesses trading with both regions must hold both numbers independently.

Before 1 January 2021, businesses trading between the UK and EU operated under a single customs framework. That unified system no longer applies. A UK EORI number is not accepted at EU customs points, and an EU EORI number carries no validity for UK customs declarations.

EU EORI number

An EU EORI number is issued by the national customs authority of the EU member state in which the business is established. For Finnish companies, the issuing authority is Finnish Customs (Tulli), and the number takes the format FI + Y-tunnus. Once issued, the EU EORI number is recognised across all EU member states — a Finnish company does not need separate EORI registrations for each country it trades with within the EU. The number serves as the primary identifier in the EU customs system for all import and export declarations.

UK EORI number

A UK EORI number follows the format GB + a 12-digit number, typically derived from the company’s UK VAT registration number. It is issued by His Majesty’s Revenue and Customs (HMRC) and is required for any business moving goods into or out of Great Britain. For example, a Finnish company importing goods from the UK presents its EU EORI number (FI-prefixed) to Finnish Customs for the import declaration, while the UK exporter uses its GB-prefixed EORI number for the UK export declaration. If the Finnish company also exports goods directly to the UK, it additionally requires its own GB EORI number from HMRC. This post-Brexit customs requirement applies to all businesses trading across both jurisdictions, regardless of size.

How do you apply for an EORI number?

Applying for an EORI number is a free, straightforward process handled through the national customs authority of the country where your business is established. Most EU member states offer online application systems, and approval typically takes between one and three working days.

To apply, you will need to prepare the following documentation:

Business registration documents or proof of identity for individuals
VAT registration number (if applicable)
Contact details and address information
Details about your import/export activities

For companies based in Finland, EORI registration is submitted through the Finnish Customs (Tulli) online service. The registration is free of charge and, once issued, your EORI number remains valid for all future import and export operations within the EU unless your business details change significantly.

Businesses established outside the EU can also obtain an EORI number through the customs authority in the EU country where they first intend to operate. This is particularly relevant for international companies establishing new trade relationships with European partners.

What happens if you import goods without an EORI number?

Importing goods without a valid EORI number results in immediate customs clearance failure. The shipment is held at the border and cannot proceed through clearance, creating delays and potentially significant storage charges while the situation is resolved.

Beyond delays, businesses may face administrative penalties that vary by country — including fines for non-compliance with customs regulations and additional processing fees. The business impact extends beyond immediate costs: suppliers face frustration, and customer deliveries are missed.

When goods are delayed due to missing EORI information, the entire supply chain is affected. Production schedules dependent on imported materials can be disrupted, while retailers waiting for stock may face empty shelves. In logistics, where timing is critical, lacking proper import documentation like an EORI number can transform a routine import into a costly operational problem.

Frequently asked questions about EORI numbers

Do I need an EORI number if I only import occasionally?

Yes. The EORI requirement applies regardless of how frequently you trade. Any business or individual importing or exporting goods between the EU and a non-EU country must hold a valid EORI number. There is no minimum volume or frequency threshold that exempts you from this requirement, and registration is free of charge.

Is my EORI number valid in all EU member states?

Yes. An EORI number issued by any EU member state’s customs authority is recognised across all EU member states. You do not need to apply for separate EORI numbers in each country where you conduct trade operations. A single EORI number covers all customs declarations submitted within the EU customs system.

How do you check if an EORI number is valid?

The European Commission provides an EORI validation tool that allows businesses to verify whether an EORI number is active and correctly registered in the EU customs system. You can search by EORI number to confirm its status. This is particularly useful when verifying the EORI details of trade partners before submitting customs declarations.

Do carriers and freight forwarders need their own EORI number?

Yes. Carriers, freight forwarders, and customs agents acting in EU customs procedures are each required to hold their own EORI numbers. The importer’s EORI number alone does not cover the activities of a forwarding or transport company acting on their behalf. Every economic operator involved in the customs process must be individually registered.

What should you do if your business details change after EORI registration?

If your business undergoes significant changes — such as a change of legal entity, company name, or address — you must update your EORI registration with the national customs authority that issued it. In Finland, this is done through Finnish Customs (Tulli). Keeping your EORI registration current ensures that customs declarations remain accurate and that trade compliance obligations are met without interruption.

Key takeaways about EORI numbers for efficient importing

Understanding EORI requirements before your first shipment is one of the most practical steps you can take to avoid unnecessary delays. Here is a concise summary of what every importer and exporter should know:
