The first two letters of a vehicle number represent the Indian state in which the vehicle is registered. For example, in Karnataka, the first two letters are ‘KA’, in Tamil Nadu, it’s TN and so on. The subsequent two numbers represent the Regional Transport Office (RTO). For example, 01, 02, and so on. The third component is the registration number of the respective vehicle. If there is no unique number left to provide, alphabets will be utilised to make it unique. The last and fourth component is the ‘IND’ signifying that the vehicle is registered in India.
