How TN RTO codes work
Every vehicle registered in Tamil Nadu carries a number plate that starts with the state code TN followed by the two- or three-digit RTO code, then a letter series, then a 4-digit number — for example TN01 XX 9999. The RTO code identifies which transport office issued the registration, which in turn tells you the city or district where the vehicle was first registered. Tamil Nadu has 147 active RTO offices.
