Indian RTO Codes Explained (With Examples)

What the state and district segments of an Indian registration number mean, and how to use them in verification work.

Indian registration numbers follow a fixed structure that encodes real information. Reading it correctly lets you sanity-check a vehicle's history before you run a single paid lookup.

The four segments

SegmentExampleMeaning
State codeKATwo letters identifying the state or union territory.
RTO district code01Two digits identifying the registering office.
SeriesMJOne or two letters allocated sequentially.
Number1234The unique vehicle number in that series.

Why it matters in verification

  • A vehicle registered far from where it has supposedly lived deserves a closer history check.
  • Commercial series in some states differ from private ones, which hints at prior usage.
  • The RTO district is where transfer paperwork originated, useful when documents look inconsistent.
Use the RTO directory to look up any code, then run the Vehicle module for the actual RC record.

FAQ

Do BH-series numbers have an RTO district code?

No. Bharat-series registrations use a different structure designed to stay valid across states, so the district segment does not apply.

Can two states share an RTO code?

The district digits repeat across states, but the two-letter state code always disambiguates them.
