New series of vehicle registration code (KL-01) with letters and digits were allotted to each district with effect from 1989. This included codes for all 14 districts of the state and KSRTC (15). Since then, in 2002, three regional transport offices such as Attingal (KL-16) and Muvattupuzha (KL-17) and Vadakara (KL-18) also came into being. In 2006, the registration codes based on sub-RTO offices were introduced.
