EORI Number in Poland

An EORI (Economic Operators Registration and Identification) number identifies your business to customs across the EU. This page explains the Poland EORI format, how to get one from Polish National Revenue Administration (KAS), and lets you validate any number instantly.

Poland EORI format

A Polish EORI is PL followed by the company's NIP with five zeros appended — 17 characters in total.

How to get an EORI number in Poland

1. Confirm your business is established in Poland (or has the required customs registration there).
2. Register through the PUESC platform (puesc.gov.pl); the EORI is issued after your entity is registered with SISC, the tax-and-customs information system.
3. Have your NIP, company name and registered address ready.
4. Receive your EORI number — usually within a few working days — and validate it below before your first declaration.

Cost, validity and processing time

• The EORI number is free — Polish National Revenue Administration (KAS) does not charge for issuing it.
• It is valid EU-wide. Once any member state has issued your EORI, you do not need another one to declare goods in other EU countries.
• A business established outside the EU registers in the member state where it first lodges a customs declaration or appoints a representative — not necessarily Poland.
• Processing normally takes a few working days, though incomplete applications are the most common cause of delay.
