REGON number
What is a REGON number?
A REGON number is a statistical identification number assigned in Poland to entities entered in the official register of the national economy maintained by Statistics Poland – Główny Urząd Statystyczny (GUS). Its legal basis is primarily the Act of 29 June 1995 on Official Statistics and executive regulations governing the register. In practice, the REGON number is used to identify businesses, organisations and certain other entities for statistical, administrative and record-keeping purposes.
The REGON register covers, among others, sole traders, commercial companies, partnerships, foundations, associations, public entities and organisational units that carry out activity requiring registration. Depending on the type of entity, a REGON number may have 9 digits or, for local units, 14 digits. The number itself does not determine legal status, representation rules or tax position. Its function is identification within public registers and data exchange between authorities and institutions.
For entrepreneurs operating in Poland, the REGON number is one of the basic registration identifiers, alongside, for example, the tax identification number – NIP – and, where applicable, the number in the National Court Register – KRS. These identifiers serve different purposes. REGON is primarily linked to the statistical register, NIP to tax matters, and KRS to court registration for entities subject to entry in that register. Confusing these numbers may lead to filing errors, incorrect documentation or delays in administrative procedures.
What is a REGON number used for?
In practice, a REGON number is used in dealings with public administration, in internal records, in some contracts, forms and reporting processes, and when verifying basic data of an entity in official databases. It helps identify a specific business or organisation and connect its data across public systems. It may also appear in accounting documents, HR files, registration forms, applications, official correspondence and compliance documentation.
A REGON number is assigned upon registration of the entity in the relevant register. For sole traders entered in CEIDG, registration data are transferred through integrated public systems. For many companies and organisations entered in KRS, data are transmitted from the court register to the statistical register. Although the assignment process is largely administrative, errors in source data, classification of activity, address details or organisational structure can affect the information recorded in the REGON database.
The number may also be relevant where an entity has separate local units, branches or establishments. In such cases, additional statistical identification may be assigned to distinguish these units for reporting and record-keeping purposes. This matters particularly for businesses with distributed operations, multiple offices or production sites, and for entities subject to sector-specific reporting obligations.
When is legal assistance regarding a REGON number useful?
Legal support may be helpful at the stage of setting up a business, registering a company, changing corporate data, opening branches, transforming an enterprise or correcting inconsistencies between official registers. Problems involving a REGON number rarely concern the number in isolation. More often, they are connected with broader issues such as registration errors, improper disclosure of business activity codes, inconsistencies between CEIDG, KRS, GUS and tax records, or difficulties in proving the correct identity of an entity in a transaction or dispute.
Private individuals may need assistance when starting a sole proprietorship, suspending or resuming activity, changing business addresses or verifying whether registration data are properly reflected in public databases. Entrepreneurs and companies may require support when restructuring, merging, dividing operations, registering branches, updating corporate records, or preparing documentation for banks, counterparties, public tenders or regulatory reviews.
A prompt consultation with a lawyer can help avoid practical mistakes that later result in administrative complications, contract risks, reporting problems, delays in registration procedures or financial losses. This is particularly important where the REGON data do not match tax records, company register entries or actual operational structure. Quick verification of the legal and factual status of the entity often reduces the risk of disputes with authorities, business partners or financial institutions.
In some cases, legal analysis is also needed to determine whether a given organisational unit should be separately disclosed, whether registration data require correction, or whether a particular change should first be made in CEIDG, KRS or another source register before it appears in the REGON database. The correct sequence of actions can be important for the validity and consistency of filings.
