Chennai North East, Tamil Nadu
Every Indian vehicle registration begins with a state code followed by a two-digit RTO number. The prefix TN09 is assigned to the Chennai North East Regional Transport Office in Tamil Nadu. Any vehicle whose number plate starts with TN09 was originally registered here.
A typical TN09 plate looks like TN09 AB 1234 — the first four characters (TN09) 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.
