When is an EORI number required? [2026]

EORI number is required ALWAYS, when goods cross the EU border (import or export) for commercial purposes.

• Company (B2B): Must always have an EORI. Without exception.
• Private individual:
• In the EU: Theoretically does not require an EORI for occasional private shipments (customs systems use the "NATURAL PERSON" number).
• In the UK: If you import goods, you usually do not need an EORI unless you import regularly.
• Samples: Yes, the company sending samples requires an EORI number.

What the current official guidance means in practice

For operational work, the current procedural rules, declaration fields and relief conditions should be checked directly against the official guidance. For this topic, the core reference points are European Commission, GOV.UK / HMRC.

Operational watch-outs

Most delays come from inconsistent data between the commercial invoice, packing list, tariff classification, reference numbers and transport assumptions. Before shipment release, confirm who is responsible for clearance, whether the data set is complete and when the declaration must be filed.

Documents and data to prepare

The minimum working pack worth preparing before speaking to customs support or filing a declaration includes:

• commercial invoice with a complete goods description
• packing list with quantities, weight and package count
• HS/CN code and origin information
• EORI number and the party responsible for the declaration

Practical notes for UK-PL operators

For regular flows, keep a stable data template: goods description, HS code, origin, Incoterms, carrier details and source documents. This shortens response time and reduces border corrections.
