I want to validate 10 digit number which should start with 91 or +91

   var expr = new Regex(@"^((\+){0,1}91(\s){0,1}(\-){0,1}(\s){0,1}){0,1}9[0-9](\s){0,1}(\-){0,1}(\s){0,1}[1-9]{1}[0-9]{7}$");

This here only matches 10 digit which start with 9.

input: 919234521098,9876543210;+919876543211;919876543212

op :919234521098,+919876543211;919876543212

Thanks

try this one:

var regex = new Regex(@"\+?91\d{8}")

This one should do the trick

\+?91\s?\d{8}

It will match both +9112345678, 9112345678, +91 12345678 and 91 12345678

Explanation:

  • +?91 will match 91 or +91(note the ?, it will make the character before optional)
  • \s? will allow to have a space after 91
  • \d{8} matches 8 digits

This expression works:

\+?91\d{8}

What it does:

  • \+?: an option + (\ escapes the +. The ? makes it optional)
  • \d{8}: 8 digits

Here is the regex:

^\+?91[0-9]{8}$

You can try this. It would match a 10 digit mobile number starting with either +91 or 91.

^[+]*91\d{10}$

^[+91]+\d{8}

This should work.

  • Hiya there, while this may well answer the question, please be aware that other users might not be as knowledgeable as you. Why don't you add a little explanation as to why this code works? Thanks! – Vogel612 Mar 31 '15 at 10:27

^\+?91[7,8,9]{1}[0-9]{9}$ This will check for + is there or not. Then for 91 and then first digit will be between 7,8,9 and then last 9 digits.
