Indian number plate format is quite simple according to
Wiki[
^]:
The first two letters of the registration plate represent the State in which the vehicle is Registered.
The next two digit numbers are the sequential number of a district. Due to heavy volume of vehicle registration, the numbers were given to the RTO offices of registration as well.
The third part is a 4 digit number unique to each plate. A letter(s) is prefixed when the 4 digit number runs out and then two letters and so on.
You can do a simple "dumb" validation in a Rexeg, but you might want to make it a bit more complex, to check state codes - I have no idea what they can be.
public static Regex regex = new Regex(
"(?<state>\\w\\w)(?<sequence>\\d\\d(?<unique>\\w*\\d\\d\\d\\d"+
"))",
RegexOptions.IgnoreCase
| RegexOptions.Singleline
| RegexOptions.CultureInvariant
| RegexOptions.Compiled
);</unique></sequence></state>
This assumes you do not want to check if the number is actually issued - that is a whole other problem!
