Phone validation regex

Question

I\'m using this pattern to check the validation of a phone number

^[0-9\\-\\+]{9,15}$

It\'s works for 0771234567 and +0

Answer 1

^+?\d{3}-?\d{2}-?\d{2}-?\d{3}$

You may try this....

How about this one....Hope this helps...

^(\\+?)\d{3,3}-?\d{2,2}-?\d{2,2}-?\d{3,3}$

Answer 2

The following regex matches a '+' followed by n digits


    var mobileNumber = "+18005551212";
    var regex = new RegExp("^\\+[0-9]*$");
    var OK = regex.test(mobileNumber);

    if (OK) {
      console.log("is a phone number");
    } else {
      console.log("is NOT a phone number");  
    }

Answer 3

/^(([+]{0,1}\d{2})|\d?)[\s-]?[0-9]{2}[\s-]?[0-9]{3}[\s-]?[0-9]{4}$/gm

+94775312412

077 531 2412

0775312412

77 531 2412

// Not matching

77-53-12412

+94-77-53-12412

077 123 12345

77123 12345

Answer 4

First test the length of the string to see if it is between 9 and 15.

Then use this regex to validate:

^\+?\d+(-\d+)*$

This is yet another variation of the normal* (special normal*)* pattern, with normal being \d and special being -.
