Pakistan Mobile Number Validator

RegEx for validating mobile numbers of Pakistan. To change it to work for your country just change 92 and 3 with your country code. Also you can change length of numbers by changing last {9}

^((\+92)?(0092)?(92)?(0)?)(3)([0-9]{9})$/gm

Test it online on RegExr or RegEx101

Explanation:

There are three groups:

Group Description
92 | +92 | 0092 | 0 Allow any integer at beginning
3 Must be having 3
001234567 Allow any integers between 0-9 but of length 9

Breakdown:
(\92)? Allow 92 and is optional
((\+92)? Allow +92 and is optional
(0092)? Allow 0092 and is optional
(0)?) Allow only 0 and is optional
(3) 3 is mandatory because Pakistani numbers starts with 3xx
([0-9]{9}) Allow any numbers from 0 to 9, but length should be exactly 9

Above RegEx will Validate

+923001234567
00923001234567
923001234567
03001234567
3001234567

Doesn't Validate

+3001234567 (92 is missing)
+933001234567 (Country code is 92)
+924001234567 (Because of missing 3)
+92300123456720 (Too many numbers)
030012345672  (Too many numbers)
30012345673 (Too many numbers)
0030012345673 (Too many numbers)

To use it in code use as mentioned by John:

  public static boolean isSingaporeMobileNo(String str) {
      Pattern mobNO = Pattern.compile("^((\\+92)?(0092)?(92)?(0)?)(3)([0-9]{9})$");
      Matcher matcher = mobNO.matcher(str);
      if (matcher.find()) {
          return true;
      } else {
          return false;
      }
  }

or

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Example {
    public static void main(String[] args) {
        final String regex = "^((\\+92)?(0092)?(92)?(0)?)(3)([0-9]{9})$";
        final String string = "// Validate it\n\n"
                               + "+923001234567\n"
                               + "00923001234567\n"
                               + "923001234567\n"
                               + "03001234567\n"
                               + "3001234567\n\n\n"
                               + "// Don't Validate \n"
                               + "+3001234567\n"
                               + "+933001234567\n"
                               + "+9230012345672\n"
                               + "+923001234567200\n"
                               + "030012345672\n"
                               + "30012345673";

    final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
    final Matcher matcher = pattern.matcher(string);
    
    while (matcher.find()) {
        System.out.println("Full match: " + matcher.group(0));
        
        for (int i = 1; i <= matcher.groupCount(); i++) {
            System.out.println("Group " + i + ": " + matcher.group(i));
                }
            }
        }
    }

To allow Dash (-) and White Space

If you want it to allow dash - or space you can use this one:

    /^((\+92)?(0092)?(92)?(0)?)(3)([0-9]{2})((-?)|( ?))([0-9]{7})$/gm

Test it online on RegExr

it will pass these two formats (along with above mentioned):

    0300 1234567
    0300-1234567

And will reject 0300- 1234567 because it has both white space and dash.

Another Solution

Another solution can be found here by Giacomo1968 on StackOverflow as:

    ^((\+92)|(0092))-{0,1}\d{3}-{0,1}\d{7}$|^\d{11}$|^\d{4}-\d{7}$
