RSIn

RSIN is a Dutch identification code used to uniquely identify legal entities and partnerships for tax and administrative purposes. The abbreviation stands for a Dutch term that describes a classement of legal entities and collaborations, and the number is issued by the Netherlands’ tax authority, the Belastingdienst. The RSIN serves as the primary identifier in tax filings, annual reports, and various government procedures.

In practice, the RSIN is used by the Belastingdienst and other government bodies to track and administer taxes, subsidies, and reporting obligations for organizations such as corporations, foundations, and associations. It is also relevant for entities with ANBI status (public-benefit organizations), where the RSIN appears in official listings and receipts associated with tax-deductible donations. The RSIN is typically presented as a numeric code and is distinct from other identifiers a company might hold, such as the KvK number assigned by the Chamber of Commerce.

Relation to other identifiers: a company or organization may have both an RSIN and a KvK number. The KvK number identifies the entity in the Dutch Chamber of Commerce register, while the RSIN is used primarily for tax administration. The two numbers may appear on different official documents, and both may be required in certain administrative contexts.

Format and visibility: the RSIN is a numeric identifier, commonly shown on official documents and public registries related to tax and nonprofit status. While it is widely used within the Dutch administrative system, the RSIN is not a general business registration number and should be distinguished from other identifiers.
