About Tamil Nadu RTOs
All vehicles registered in Tamil Nadu carry the TN prefix. The two-digit number following TN identifies the specific district or city RTO where the vehicle was registered. Lower numbers are generally older, more central offices — while higher numbers are newer or outer-district RTOs.
To check the registration details or transfer an RC for any TN-series vehicle, visit the official Parivahan portal or the relevant Tamil Nadu RTO office in person.
