CEIDG, i.e. the Central Register and Information on Economic Activity, is the state register of entrepreneurs who are natural persons — mainly sole proprietorships (JDG) and partners in civil-law partnerships. It is run by the minister competent for the economy in an IT system, and the entry and every application are free of charge. Through CEIDG a business is registered, changed, suspended and closed, and counterparties are also checked.
Who is covered by CEIDG and who by KRS
In Poland two main business registers operate. CEIDG covers natural persons running business activity. Commercial companies — limited liability (sp. z o.o.), joint-stock, general and limited — are entered in KRS (National Court Register), which is kept by the courts. A civil-law partnership is not separately registered in CEIDG: each of its partners is entered as an entrepreneur.
| Feature | CEIDG | KRS |
|---|---|---|
| Who is entered | entrepreneurs who are natural persons | commercial companies, foundations, associations |
| Who runs it | the minister competent for the economy | registry courts |
| Fee for an application | none | court fee, e.g. PLN 250 for amending an entry |
| Channel | biznes.gov.pl or commune office | Court Registers Portal |
What data the entry contains
The Act lists a catalogue of registration data. The most important are:
- the entrepreneur's first and last name and the firm name under which they operate (with any additional descriptors),
- NIP and REGON numbers,
- service address, the address of the fixed place of business and additional places,
- PKD codes, start date of the business, information on suspension or resumption,
- contact details (if the entrepreneur has provided them),
- information on proxies and commercial representatives, if published.
Some information is entered in the register on an official basis — e.g. from the PESEL register or the address register, from courts (bankruptcy, bans on business activity) and from other systems. Data are published no later than within 3 working days of the entry. When providing contact details, you may object to their publication. Remember that the entrepreneur must have legal title to the properties whose addresses they enter in CEIDG — e.g. a lease or the owner's consent.
What you can arrange through CEIDG
- Business registration — a single CEIDG-1 application also passes the data to the tax office, ZUS (Social Insurance Institution) and GUS (statistical office). We describe it step by step in the article How to open a JDG in 2026.
- Data changes — e.g. address, PKD codes, firm name or bank account.
- Suspension and resumption of activity — more in the article Suspending business activity 2026.
- Striking off after ending activity — bearing in mind that striking off does not remove the data from the register; the entry's history remains available.
- Power of attorney — the entrepreneur may publish in CEIDG information about a proxy, e.g. to file applications on their behalf.
- Counterparty verification — the search engine lets you check whether a firm exists, is active and at what address.
How to check a counterparty in CEIDG
Before signing a contract or paying an advance, it is worth spending two minutes on verification. In the search engine on biznes.gov.pl enter the NIP, REGON or the entrepreneur's surname and check:
- entry status — active, suspended or struck off,
- whether the address and name match the data in the contract or on the invoice,
- whether PKD codes match the service the firm is to perform,
- whether there are any references to bankruptcy or a business ban.
Where the counterparty is a company, look for the same information in KRS, and check the VAT status on the list of VAT payers.
Deadlines to watch
The entrepreneur has 7 days from the day of the change to file an application to update most data, including the firm name, addresses and PKD codes. Some data change on an official basis, but the entrepreneur is responsible for the currency of addresses and the object of activity. The application can be signed with the trusted profile, a qualified signature or a personal signature from the e-dowód (e-ID), and in paper form — by hand at the commune office.
A confirmation of the entry is an electronic document or a printout from the CEIDG system. In practice, it is enough to download a printout from the search page — no separate application to the office is needed.
Example: changing the business address
A developer running a sole proprietorship moves on 1 October 2026 from Wrocław to Gdańsk, and the business is registered at the home address.
- They sign a lease for the new flat, which gives them legal title to the premises.
- By 8 October they log in to biznes.gov.pl with the trusted profile and file an application to amend the entry: service address and the address of the fixed place of business.
- They indicate the new tax office if the competence changes — the data will reach the office automatically.
- They update the address on invoices, in client contracts and in bank-account settings.
- After a few days they check in the CEIDG search engine that the new address is visible.
The most common mistakes
- Entering a premises address without a contract or the owner's consent.
- Changing the scope of activity without adding PKD codes in CEIDG.
- Giving the accounting office the trusted-profile login instead of publishing a power of attorney.
- Believing that striking off from CEIDG closes everything — settlements with the tax office and ZUS must be ended separately.
How Good Balance can help
We prepare and file applications in CEIDG on behalf of clients — from registration, through data and PKD-code changes, to suspension and striking off — under the sole proprietorship service. When the business grows and it is worth moving to a company, we will also handle the company registration in KRS.
