Thiruvananthapuram, Kerala
Every Indian vehicle registration begins with a state code followed by a two-digit RTO number. The prefix KL01 is assigned to the Thiruvananthapuram Regional Transport Office in Kerala. Any vehicle whose number plate starts with KL01 was originally registered here.
A typical KL01 plate looks like KL01 AB 1234 — the first four characters (KL01) identify the RTO, the two letters are the series, and the last four digits are the unique vehicle number.
Decoding the RTO tells you where a vehicle was registered — but not who owns it. Use the OSINTS.xyz Vehicle & Owner lookup to pull the registered owner name, RC status, insurance, PUC and challan history from the number plate.
