Registrant Information Number (RIN)

A Registrant Information Number (RIN) in Ontario is a unique 9-digit identifier assigned to individuals or organizations registered with the Ministry of Transportation (MTO).

It is primarily used for vehicle registration and licensing purposes. The RIN ensures that vehicle ownership, driving records, and related transactions are accurately linked to the correct individual or business.

A RIN may be required when purchasing or transferring a vehicle, registering for a driver's license, or conducting other transportation-related services. The RIN is tied to personal information, so it helps streamline administrative processes and ensure accuracy in records.

Individuals can obtain a RIN through Service Ontario offices or through authorized automotive dealers when registering a vehicle.
