Vehicle registration number
Decodes state and RTO from plate format only — not owner details. For RC status use the official Vahan portal.
How to use Plate Decoder
Indian vehicle number plates carry useful information: the state, the RTO that registered the vehicle and a series number. This decoder reads a registration number and tells you the state and RTO code, and recognises Bharat (BH) series plates. It is helpful when you are buying a used vehicle, checking where a car is registered or simply curious about a plate you see on the road.
How to use the plate decoder
Type the registration number with or without spaces, for example DL3CAB1234 or MH12AB1234. The tool splits it into state, RTO, series and number and shows the state and the registering office where known.
The decoder reads only what is printed in the number. It does not look up the owner or the vehicle’s history. For paperwork checks, use the official Parivahan services.
- Enter the full plate; spaces and hyphens are ignored
- BH series plates are detected separately
- The result shows the state and RTO code only
How to read an Indian number plate
A standard plate follows the pattern SS NN XX NNNN. SS is the two-letter state or union territory code (DL, MH, KA, TN), NN is the two-digit RTO or district code, XX is a one-to-three-letter series, and the last four digits are the unique number.
For example, KA01AB1234 was registered in Karnataka at the RTO coded 01, which is Bengaluru Central. The series letters change as numbers run out for a particular RTO.
BH series and other special plates
The Bharat series uses the format YY BH NNNN XX, where YY is the year of initial registration, BH marks the series, NNNN is a four-digit number and XX is one or two letters. It is meant for people who relocate across states often so they do not need to re-register.
Other special plates include green-background plates for electric vehicles, yellow plates for commercial vehicles and plates with arrow marks for military vehicles. Colours indicate the usage category.
- White plate with black text: private vehicle
- Yellow plate with black text: commercial vehicle
- Green plate: electric vehicle (white text on green for private)
Checking a used vehicle safely
Decoding the plate tells you where the vehicle was first registered, which is only one clue. Before buying, verify the RC, check for pending challans, confirm the insurance and verify the chassis and engine numbers against the documents. If the registration state differs from the seller’s city, ask about the NOC and re-registration status.
