What Are RTO Codes in Bihar?

Every Regional Transport Office (RTO) in Bihar is assigned a unique two-digit code by the Ministry of Road Transport and Highways (MoRTH). This code forms the second segment of a vehicle's registration number, immediately after the state prefix BR.

For example, a vehicle registered at Patna carries the code BR-01 in its number plate. This system helps law enforcement, insurance companies, and traffic authorities instantly identify where a vehicle was originally registered.

Bihar currently has 38 registered RTOs spread across its districts and cities, each serving vehicle owners in that region.
