GSRTC bus number plate format, explained
Every GSRTC bus carries a plate like GJ-18-ZT-1028. Here is what each part means, and why getting it exactly right matters when you search.

Reading the plate
Gujarat ST buses use the standard Indian vehicle registration format: GJ for the state, a two-digit RTO (registration) code, a letter series, and a four-digit number — for example GJ-18-ZT-1028. The RTO code identifies where the vehicle was first registered, not the route it runs — a Rajkot-registered bus (GJ-3) can run anywhere in the state.
You'll usually find the plate painted on the front bumper and above the windscreen, and again on a metal plate at the rear.
Why the exact plate matters for tracking
Live tracking looks the bus up by that exact registration, so a wrong digit returns nothing rather than the wrong bus. ST Tracker corrects common punctuation differences — spaces instead of dashes, lowercase letters — automatically, but a mistyped digit or letter still won't match.
Don't have the plate, or not sure you read it right? Search by the two stations you're travelling between instead — see the timetable guide — and pick the right departure from the list rather than typing a plate at all.

Questions people ask
What does GJ-18 mean on a GSRTC bus?
GJ is the Gujarat state code, and 18 is the RTO (registration) code for where the bus was first registered (e.g. Gandhinagar / Ahmedabad region). It does not indicate which route the bus currently runs.
Can I track a bus with only part of the plate?
No — tracking needs the full registration to match the operator’s records. If you only caught part of it, search by route instead and pick the bus from the departure list.
Does it matter if I type the plate with or without dashes?
No. ST Tracker normalises spacing and dashes automatically before searching, so GJ18ZT1028 and GJ-18-ZT-1028 both work.
