Want a regex for validating Indian Vehicle Number Format?

Question

Hello everyone here...

I need to build up a swing application related to vehicle registration and in which i want to do input the vehicle number of indian standard, like

Answer 1

Based on the Wikipedia spec:

^[A-Z]{2}[ -][0-9]{1,2}(?: [A-Z])?(?: [A-Z]*)? [0-9]{4}$

• 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.
• In some states (such as the union territory of Delhi, and the state of Gujarat) the initial 0 of the district code is omitted; thus Delhi district 2 numbers appear as DL 2 not DL 02.
• The National Capital Territory of Delhi has an additional code in the registration code: DL 01 C AA 1111

Answer 2

AP-05-BJ-9353

DL 0 AA 1111

DL 1 A 1111

Answer 4

If you are looking for number plate(VRN) then use following regex

^[A-Z|a-z]{2}\s?[0-9]{1,2}\s?[A-Z|a-z]{0,3}\s?[0-9]{4}$

Answer 5

Try this

^[A-Z]{2}\s[0-9]{2}\s[A-Z]{2}\s[0-9]{4}$

^ means start of string
[A-Z]{2} means 2 characters in the range of A through Z
\s means white space
[0-9]{2} means 2 characters in the range of 0 through 9
\s means white space
[A-Z]{2} means 2 characters in the range of A through Z
\s means white space
[0-9]{4} means 4 characters in the range of 0 through 9
$ means end of string

Based on what you said in your question this should be a very broad check against proper format, but I have a feeling that there are more specific regulations on how the license plates are numbered. Let me know if there are additional constraints for the regex.

Answer 6

just check it out for whitespace only...

  function isValidNumber($Number){
         $pattern = "^[a-zA-z]{2}\s[0-9]{2}\s[0-9]{4}$";
         if (eregi($pattern, $Number)){
            return true;
         }
         else {
            return false;
        }
    }
