YTJrekisterin

YTJrekisterin, commonly referred to as the YTJ register, is a central public repository of information about Finnish companies and other registered entities. It consolidates core data to serve authorities, businesses, and private individuals by providing official, up-to-date information about registered organizations.

The register includes data such as the official name, business identity code (Y-tunnus), legal form, start date, and current status. It also records addresses (registered and correspondence), the field of business, and changes to the entity’s information. In addition, the YTJ collects details on organizational changes such as name changes, address updates, mergers, dissolutions, and alterations in legal form. Information in the register is sourced from official filings and maintained by the authorities responsible for business and civil registries.

Access to the YTJ data is provided through the ytj.fi service. Basic searches are typically free and allow users to view essential information about entities. More detailed information or official extracts can be obtained through further services. The YTJ aims to improve transparency, facilitate administrative procedures, and support reliable verification in processes such as licensing and public procurement. Privacy protections apply to personal data, and data use is governed by Finnish public-information and data-protection laws.

Governance and interoperability: The YTJ operates as a joint system within the Finnish public sector, drawing from the Trade Register and other official sources to ensure consistency across registers. It serves as a practical entry point for obtaining primary, officially verified information about businesses and associations in Finland.
