// you can relax about usage of hiphens and other special characters, we'll strip 
// it down internally later ;)
var number = "4481730";
var phone = Phone.getPhoneInternational(number);
console.log(phone); // { countryCode: "1", nationalDestinationCode: "303", 
//number: "4481730", isMobile: true, isValid: true }

Validates a phone number after which returns true or false.

var Phone = require("@vtex/phone");
var brazil = require("@vtex/phone/countries/USA");

// Given a phone number in international notation
var number = "+13034481730";
var result = Phone.validate(number);
console.log(result); // true
