Poland issues EORI numbers through the National Revenue Administration (KAS). Registration is free when submitted via official channels.
In Poland, the EORI (Economic Operators Registration and Identification) number is
the identifier that National Revenue Administration (Krajowa Administracja Skarbowa)
assigns to businesses moving goods across the customs border. It starts with the prefix
PL followed by a national
identifier — for example PL123456789012345, and one registration is valid for customs declarations in every EU member state.
Customs will not process imports or exports declared in your name without it.
Any business established in Poland that lodges customs declarations — or is named as importer or exporter on them — needs an EORI number before goods move. That includes companies, sole traders and partnerships importing stock from outside the EU, exporting to international customers, or selling through online marketplaces that ship across customs borders. Even when a freight forwarder or courier files the declaration for you, the declaration still carries your EORI.
A core rule of the EU system: you register once, in the member state where your business is established — for a business established in Poland, that means applying to National Revenue Administration (Krajowa Administracja Skarbowa). The PL-prefixed number you receive is then valid for customs declarations in all 27 EU member states: you do not need a separate EORI for each country you trade with inside the EU. Non-EU businesses that first declare in Poland can also request their EORI there.
Note that an EU EORI is not valid for Great Britain. If your business in Poland also imports into the UK in its own name, it needs a separate GB EORI from HMRC — see our UK EORI guide.

EU EORI validation (EU EOS) + KAS confirmation. Because PL numbers sit in the EU-wide EOS database, any of your European trading partners can verify your number too — many businesses run a quick check on new suppliers and customers before the first shipment.
Once active, your EORI appears on every customs document tied to your business: import and export declarations, transit paperwork, safety and security filings, and any customs authorisations you hold. Couriers such as DHL, FedEx and UPS will ask for it before they can clear commercial goods in your name. Keep the exact string handy in your shipping profiles — a single mistyped character is enough to stop a consignment at the border. You can compare your number against the national pattern in our EORI format hub, which covers every country's structure with valid examples.
If your EORI is newly issued, validate it with the free checker before your first shipment.
