If you've spotted a number plate that doesn't fit the usual two-letter-state-code pattern — something like 22BH1234AB instead of MH12AB1234 — you've seen the Bharat Series, a newer registration format introduced specifically to solve a long-standing headache for people who relocate frequently across states.
The problem BH-series was built to solve
Under the traditional state-based registration system, moving to a new state technically required re-registering your vehicle within a set period, involving an NOC from your original RTO and fresh registration (plus, in many cases, additional road tax) at the new state's RTO. For people who relocate every few years for work — defence personnel, central government employees, and staff at companies with offices across many states — this created repeated cost and paperwork for the same vehicle.
How BH-series registration works
A BH-series plate follows the format YY BH #### XX — a 2-digit year of registration, the fixed letters "BH," a 4-digit number, and 1-2 series letters. Unlike state-prefixed plates, it isn't tied to any single state's RTO, so the vehicle doesn't require re-registration when the owner moves to a different state.
Who's eligible for BH-series registration
Eligibility is specifically defined: defence personnel, employees of central government or state government departments with transferable postings, and employees of private companies or organizations that have offices in four or more states or union territories. It's a targeted solution, not an option freely available to every vehicle owner.
Road tax under BH-series
BH-series vehicles pay motor vehicle tax differently from state-registered vehicles — typically in a structure designed for the portability the format offers, often paid in installments over a period rather than as a single lump sum, reflecting the format's design for owners who may relocate again before a long single-payment period would otherwise end.
Decoding a BH-series plate
Our vehicle plate decoder recognizes the BH-series format specifically, extracting the registration year and series letters, and correctly notes that — unlike a standard state plate — a BH-series number doesn't map back to a single state's RTO office, since it's issued through a centralized, portable process by design.
Can an existing state-registered vehicle be converted to BH-series?
In many cases, yes, subject to eligibility and the applicable transition process through the vehicle owner's RTO — but the specific procedure and any tax adjustment implications are worth confirming directly with the relevant transport department before proceeding, since rules can vary by state in their implementation details.
