Best method you can check it here

http://www.moodycoder./custom-validator-method/

also you can check below code

static isValidMobile(control: FormControl): any {

    let regExp = /^[0-9]{10}$/;

    if (!regExp.test(control.value)) {
        return {"invalidMobile": true};
    }
    return null;
}

it works like a charm for me...

i've used third party library named intl-tel-input.

1- First install jQuery

npm install --save jquery

Now, within any of the app files import jquery like

import $ from "jquery"; 

and it will using like

$('#elemId').width();

2- install intl-tel-input library

npm install intl-tel-input --save

Now, within any of the app files import int-tel-input like

import 'intl-tel-input';

and using like below:

ngOnInit(): any {
    let telInput = $("#elemtId");
    let output = $("#output");

    telInput.intlTelInput();
    // listen to "keyup", but also "change" to update when the user selects a country
    telInput.on("keyup change", function() {
      var intlNumber = telInput.intlTelInput("getNumber");
      if (intlNumber) {
        output.text("International: " + intlNumber);
      } else {
        output.text("Please enter a number below");
      }
    });
  }

home.html

<p id="output">Please enter a number below</p>
<input id="elemtId" type="tel">
