# Dutch organisation identification number (OIN) (`nl_oin`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Organisatie-identificatienummer (OIN), the 20-digit number that identifies a government organisation or another party in Dutch government data exchange (Digikoppeling) and in PKIoverheid certificates. Logius keeps the register. An OIN is an 8-digit prefix naming the source register, the main number from that register and zeros up to 20 digits. The prefixes are 00000001 RSIN, 00000002 Fi-nummer, 00000003 KVK number (preferred for new OINs), 00000004 sub-OIN, 00000006 main number issued by Logius, 00000007 BRIN, 00000008 foreign organisation, 00000009 UZI, 00000010 TRR-BD of the tax service, and 00000099 test OINs.
