Start with the state prefix
The first letters identify the broader state or union territory family: DL → Delhi, MH → Maharashtra, KA → Karnataka.
This narrows the vehicle into the correct administrative family.
Use the numeric block to identify the office
After the state prefix, the next number block identifies the local registering authority, regional transport office, or zonal office.
In several states, this maps to an office or transport authority rather than a district name.
Read the series letters and final number
Once the state family and office code are understood, the remaining letter series and final number distinguish the vehicle record within that office's sequence.
These later characters identify the full plate but do not change which office issued the registration.
Frequently asked questions
Can the RTO be identified from the first two letters alone?
No. The first letters identify the state/UT family. The following numeric block is what narrows it to a specific office.
Why does a code sometimes map to an office instead of a district?
Because many registration systems are structured around transport authorities or zonal offices, not simple district boundaries.
