How to search
Use company search with jurisdictionCode: "pl". Pass a name as companyName or a registration number as companyNumber. companyNumber is read as krsNumber.
Fields
An advancedQuery for Poland accepts these fields:
| Field | What it does |
|---|---|
name | Company name to search for. |
krsNumber | KRS number - 10-digit Polish company register number (e.g., '0000612344'). Numbers shorter than 10 digits are automatically zero-padded. |
nip | NIP tax identification number - 10-digit number (e.g., '5272722557'). |
regon | REGON statistical number - 9 or 14 digit number (e.g., '360228092'). |
Examples
{ "jurisdictionCode": "pl", "advancedQuery": { "krsNumber": "0000612344" }}Other accepted field combinations: nip and regon.
Search notes
- If a search request includes krsNumber together with nip, regon, or name, only krsNumber is used. Send krsNumber alone, or omit it and use nip/regon/name.
- If the value passed as krsNumber is not a KRS number the register recognizes, the search retries it as a NIP or REGON before reporting no result, so a NIP or REGON passed as krsNumber still resolves.
- A lookup by krsNumber, nip, or regon returns the same kausateId for the same entity. CEIDG sole proprietors have no KRS number and can only be found via nip or regon.
- A search by 14-digit REGON uses only the first 9 digits, so it matches the parent entity, not the specific branch.
- For a very common name the registries return only a few dozen of the matches. Add more of the full company name to find a specific company.
Company identifiers
A registration number sent as companyNumber is matched against the searchable schemes below; you do not name the scheme. All of them can appear in a company’s identifiers.
| Identifier | Type | Format |
|---|---|---|
| Polish KRS Number Polish National Court Register (KRS) number - 10 digits | pl_krs_number | ^\d{10}$ |
| Polish PESEL Polish national identification number (PESEL) for a natural person - 11 digits encoding date of birth, gender, sequence and checksum | pl_pesel | ^\d{11}$ |
| Polish CEIDG ID Polish Central Register of Business Activity (CEIDG) unique identifier | pl_ceidg_id | ^[0-9A-F]{8}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{12}$ |
| Polish NIP Polish Tax Identification Number (NIP) - 10 digits | pl_nip | ^\d{10}$ |
| Polish REGON Polish statistical number (REGON) - 9 or 14 digits | pl_regon | ^\d{9}(\d{5})?$ |
| Family Foundation RFR | pl_family_foundation_rfr | No fixed format |
| KRS | pl_krs | No fixed format |
| Legacy Commercial Register Number | pl_legacy_commercial_register_number | No fixed format |
| RFR Number | pl_rfr_number | No fixed format |
Identifier notes
- A PESEL, the national ID attached to individuals in ownership and representative data, encodes a date of birth in its first six digits, with the century folded into the month digits (01–12 → 1900s, 21–32 → 2000s, 41–52 → 2100s, 61–72 → 2200s, 81–92 → 1800s). The birth date is not reported separately, so a masked PESEL (only its first digit revealed) also hides the birth date.
- A KRS company number carries no check digit, so a mistyped but well-formed 10-digit number passes format validation and returns an ordinary not-found result. Only clearly invalid input, such as all-zeros, is rejected.
- A REGON number comes in two lengths: the 9-digit form identifies the legal entity, and the 14-digit form adds a 5-digit suffix identifying one local or branch unit of it. Some lookups accept only the 9-digit form; the first 9 digits of a 14-digit REGON are the entity identifier.
- Poland's EORI customs number is 'PL' + the 10-digit NIP + a fixed '00000' suffix (17 characters total), not the bare 'PL' + NIP. It is only needed to trade outside the EU, so most Polish companies have none. It appears among a company's identifiers only when confirmed registered.

Local notes
Gotchas
| Topic | Details |
|---|---|
| Shareholder detail depends on form | An sp. z o.o. gets share counts and nominal values for partners holding at least 10%, so the published stakes can legitimately sum to less than 100%. Partnerships (sp.j., sp.k., sp.p., S.K.A.) list their partners with no percentage, each marked general or limited partner where the register says so. Joint-stock forms (S.A., P.S.A., S.E.) return only a sole shareholder, when one holds every share. A corporate holder outside the Polish registers comes back with no jurisdiction, because the register gives no country for it. |
| Struck-off companies still report | A struck-off (deregistered) company still returns a full company report, built from its historical filing record. Well over half of the companies you can look up in Poland's court register have been struck off. A company in liquidation, bankruptcy, restructuring or suspension still has an up-to-date current record, and its status says which. |
| CEIDG is a natural person | A sole proprietorship (CEIDG) is a natural person: no KRS number, shareholders, beneficial owners, or financial statements, and a different lookup identifier. |
| Accounts from the VAT whitelist | Bank account numbers come from Poland's VAT whitelist, checked before settling a domestic invoice of 15,000 PLN or more: an unlisted account costs the payer the deduction and creates joint liability for the counterparty's VAT debt. It is a snapshot, not a live balance. |
| Empty can be correct | An empty bank-accounts result can mean the company is legitimately unregistered for VAT. An empty beneficial-ownership result can mean an exemption: the register exempts listed companies, their direct subsidiaries, and sole proprietorships (natural persons, out of scope). |
| Financial statements often empty | Most Polish companies have never filed in the digital repository, and IFRS filers submit only PDFs that can't be structured. One filing, when available, yields two fiscal years: current and prior. |
| Masked names resolved separately | Director and board names the register masks are usually returned in full. Masked shareholder names can stay masked when there is no clear match. |
| Indirect interest is Polish prose | For an indirect beneficial owner, the interest description may be untranslated Polish prose copied from the filing, describing the chain through an intermediary. |
| Derived VAT number, real EORI | The EU VAT number is structurally derived (PL + NIP), not confirmed against VIES. An EORI appears only once the EU registry confirms it, and is normally absent for companies trading only within the EU. |
| PLN stake divided by capital | When a beneficial owner's stake is shown only as a PLN amount (common for sp. z o.o.), the percentage is that amount divided by registered share capital, capped at 100% for rounding or mixed share classes. |
| Indirect stakes are not priced | When a beneficial owner's stake is described only in prose about an indirect chain, no percentage is returned: the figures in that text are the links of the chain, not the owner's effective stake. The prose is returned verbatim in the interest details. |
