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
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

+3001234567 (92 is missing)
+933001234567 (Country code is 92)
+924001234567 (Because of missing 3)
+92300123456720 (Too many numbers)
030012345672 (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));
}
}
}
}
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})$/gm
Test it online on RegExr
it will pass these two formats (along with above mentioned):
0300 1234567
0300-1234567
And will reject 0300- 1234567 because it has both white space and dash.
Another solution can be found here by Giacomo1968 on StackOverflow as:
^((\+92)|(0092))-{0,1}\d{3}-{0,1}\d{7}$|^\d{11}$|^\d{4}-\d{7}$
