How SK RTO codes work
Every vehicle registered in Sikkim carries a number plate that starts with the state code SK followed by the two- or three-digit RTO code, then a letter series, then a 4-digit number — for example SK01 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. Sikkim has 8 active RTO offices.
