What Are RTO Codes in Assam?

Every Regional Transport Office (RTO) in Assam 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 AS.

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

Assam currently has 32 registered RTOs spread across its districts and cities, each serving vehicle owners in that region.
