What is the Indian plate format?

The standard format is SS NN LL NNNN: a two-letter state or union territory code, a two-digit RTO district code, one to three series letters, and a number up to four digits. For example, MH 12 AB 1234 is from Pune, Maharashtra.

What does the state code mean?

The first two letters identify the registering state or union territory, such as MH for Maharashtra, DL for Delhi, or KA for Karnataka. The validator checks the code against the RTO table of 36 states and territories.

What is the Bharat (BH) series?

The BH series is a national registration for vehicles that move between states, formatted as YY BH NNNN LL (a registration year, the BH marker, a number, and series letters). It avoids re-registration when the owner relocates.

Does a valid format mean the plate is registered?

No. This tool validates the structure and the state code only. To confirm a plate belongs to a registered vehicle you must query the Parivahan / VAHAN database.

Why does my plate fail?

The most common reasons are an unrecognised state code, a missing RTO district number, or extra characters. Re-check the two-letter state code and that the parts follow the SS 00 LL 0000 order.

India Vehicle Registration Validator

An Indian vehicle registration number packs the registering state, RTO district, and a sequential series into one plate. This free validator confirms a plate follows the standard format, checks the state code against the official table, and recognises the newer national Bharat (BH) series. It is built for Indian logistics and vehicle-history applications.

How it works

The tool normalises the input (uppercased, spaces removed) and parses the standard structure:

State / UT code: the first 2 letters, validated against the RTO’s table of 36 states and union territories (e.g. MH = Maharashtra, DL = Delhi).
RTO district code: the next 2 digits, identifying the registering Regional Transport Office.
Series: 1–3 letters allocated sequentially as numbers run out.
Number: up to 4 digits (1–9999).

It also detects the BH series pattern YY BH NNNN LL, used for vehicles registered for inter-state mobility, and reports it separately.

Example

Validate MH 12 AB 1234:

State code = MH   -> Maharashtra
RTO        = 12   (Pune)
Series     = AB
Number     = 1234

The plate is well-formed and registered in Maharashtra.

Notes

A valid result confirms the structure and a recognised state code; it does not confirm the plate is currently assigned to a vehicle — for that, query the Parivahan / VAHAN database. Older plates may carry shorter series, and some legacy state codes (such as OR for Odisha) are still in circulation. All processing happens locally in your browser.
