Tambaram, Tamil Nadu
Every Indian vehicle registration begins with a state code followed by a two-digit RTO number. The prefix TN05 is assigned to the Tambaram Regional Transport Office in Tamil Nadu. Any vehicle whose number plate starts with TN05 was originally registered here.
A typical TN05 plate looks like TN05 AB 1234 — the first four characters (TN05) 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.
