RTO Codes India: How to Read a Number Plate
A car with a “DL” plate cuts you off in Bangalore traffic. You instantly know it’s from Delhi. Those two letters on a vehicle’s number plate reveal the state and district where it’s registered. This system, managed by the Regional Transport Office (RTO), makes every vehicle uniquely identifiable across India.
In this article, I’ll decode the structure of an Indian number plate, list all state RTO codes, and show you how to find the exact RTO office for any vehicle. Use our free RTO Code Finder to search by number or by state.
Structure of an Indian Number Plate
Example: MH 12 AB 1234
- MH: State code (Maharashtra).
- 12: District RTO code (in this case, Pune).
- AB: Running series (alphabets).
- 1234: Unique 4‑digit number.
Additionally, newer plates follow the IND format with a blue “IND” and a hologram.

FAQ
1. Can a vehicle have two RTO codes?
No. A vehicle is registered in one RTO. However, you can re‑register it in a different state if you move permanently.
2. What does “BH” series mean?
The Bharat series (BH) is a new all‑India registration for central government employees and private sector employees with transferable jobs. It eliminates the need to re‑register when moving states.
3. How do I find the RTO code of a particular district?
Use the RTO Code Finder and select the state; the full district list appears.
4. Are there different codes for commercial and private vehicles?
The registration code remains the same; the vehicle type is indicated by the plate colour (white for private, yellow for commercial, green for electric, etc.).
