rekisteröitynumero

The term rekisteröity numero, literally translated as “registered number,” refers to a unique identifier assigned by an official registry in Finland. It is used to anonymously identify a wide range of entities, including legal persons, vehicles, and properties. The number is generated by the relevant agency and is permanently associated with the entity for the duration of its existence in that registry.

In the context of businesses, the rekisteröity numero is commonly called a y-tunnus and is issued by the Finnish Trade Register. This nine‑digit identifier, often written in the format 1234567-8, allows companies to conduct legal, financial and contractual activities. Citizens receive a rekisteröity numero for each residence or property, which is used in building and land registration records. Vehicle owners are provided with a registration number (rekisteriin merkitty numero) by the Finnish Transport and Communications Agency, the number being essential for traffic law enforcement and vehicle registration in the national fleet database.

The purpose of a rekisteröity numero is to provide a stable, unambiguous reference that facilitates data retrieval, cross‑referencing and compliance audits across public and private institutions. Because the number originates from an official source, it is considered a trusted and reliable identifier. In practice, those who deal with legal documentation, tax administration and public services frequently encounter the term and rely on the associated number for identification and verification procedures.

Overall, the rekisteröity numero plays a central role in Finland’s administrative infrastructure, ensuring that each entity can be uniquely tracked, managed and linked to its corresponding records in national databases.
