About this package

A simpler and smaller NPM package which can be used to verify and format contact numbers. The package takes advantage of Regex patterns, rather than relying on Google’s libphonenumber library’s validation rules, to validate different types of contact numbers for different countries.

Installation

With NPM:

npm install validate-contact-number --save

With Yarn:

yarn add validate-contact-number

Usage

With Frontend frameworks like React, Angular, Vue, Svelte.

import { isValidContactNumber } from "validate-contact-number";

In Node:

const validateContactNumberPackage = require("validate-contact-number");

In React-Native:

import { isValidContactNumber } from "validate-contact-number";

API

import {
  isValidContactNumber,
  isValidLandlineNumber,
  isValidMobileNumber,
  validateContactNumber,
  formatContactNumber,
} from "validate-contact-number";

isValidContactNumber

Returns a boolean (true | false) based on whether a contact number (mobile | landline) belongs to a country. The functions accepts two argument contactNumber and countryISO | countryISO[]

Example:

// javascript
import { isValidContactNumber } from "validate-contact-number";
const validContactNumber = "9876543210"; // same goes for 09876543210, +919876543210
const countryISO = "IN"; // Indian ISO

console.log(isValidContactNumber(validContactNumber, countryISO)); // true
import { isValidContactNumber } from "validate-contact-number";
const validContactNumber = "2212345678"; // same goes for +91 22 1234 5678
const countryISOList = ["IN", "MY", "AF"]; // a list of countries

console.log(isValidContactNumber(validContactNumber, countryISOList)); // true

isValidMobileNumber

Returns a boolean (true | false) based on whether a mobile number belongs to a country. The functions accepts two argument mobileNumber and countryISO | countryISO[]

Example:

import { isValidMobileNumber } from "validate-contact-number";
const validMobileNumber = "9876543210"; // same goes for 09876543210, +919876543210
const countryISO = "IN"; // Indian ISO

console.log(isValidMobileNumber(validMobileNumber, countryISO)); // true
import { isValidMobileNumber } from "validate-contact-number";
const validMobileNumber = "9876543210"; // same goes for 09876543210, +919876543210
const countryISOList = ["IN", "MY", "AF"]; // a list of countries

console.log(isValidMobileNumber(validMobileNumber, countryISOList)); // true

isValidLandlineNumber

Returns a boolean (true | false) based on whether a landline number belongs to a country. The functions accepts two argument landlineNumber and countryISO | countryISO[]

Example:

import { isValidLandlineNumber } from "validate-contact-number";
const validLandlineNumber = "+91 22 1234 5678"; // same goes for 22 1234 5678
const countryISO = "IN"; // Indian ISO

console.log(isValidLandlineNumber(validLandlineNumber, countryISO)); // true
import { isValidLandlineNumber } from "validate-contact-number";
const validLandlineNumber = "+91 22 1234 5678"; // same goes for 22 1234 5678
const countryISOList = ["IN", "MY", "AF"]; // a list of countries

console.log(isValidLandlineNumber(validLandlineNumber, countryISOList)); // true

validateContactNumber

Returns a detailed response about contact number like country name, country code, contact type etc. Functions accepts a required contactNumber as argument. The contact number is matched with available regex patterns of countries. The country details are returned when contact number satisfies the country regex (either mobile or landline).
Function also accepts optional argument countryISO | countryISO[] which can narrow down the available regex patterns against which the contact number needs to be checked.

Example:

// Without countryISO
import { validateContactNumber } from "validate-contact-number";
const validLandlineNumber = "+91 22 1234 5678"; // same goes for 9876543210

const contactDetails = validateContactNumber(validLandlineNumber);
// conatctDetails: {valid: true, countryISO: "IN", contactNumber: "2212345678", dialCode: "+91", countryName: "India", contactType: "landline" }

// invalid number
const invalidLandlineNumber = "+91 22 1234 56";
const contactDetails = validateContactNumber(invalidLandlineNumber);
// conatctDetails: {valid: false }
// With countryISO
import { validateContactNumber } from "validate-contact-number";
const validLandlineNumber = "+91 22 1234 5678"; // same goes for 9876543210
const countryISO = "IN"; // Indian ISO

const contactDetails = validateContactNumber(validLandlineNumber, countryISO);
// conatctDetails: {valid: true, countryISO: "IN", contactNumber: "2212345678", dialCode: "+91", countryName: "India", contactType: "landline" }

// invalid number
const invalidLandlineNumber = "+91 22 1234 56";
const countryISO = "IN"; // Indian ISO
const contactDetails = validateContactNumber(invalidLandlineNumber, countryISO);
// conatctDetails: {valid: false }
// With a list of countryISO
import { validateContactNumber } from "validate-contact-number";
const validLandlineNumber = "+91 22 1234 5678"; // same goes for 9876543210
const countryISOList = ["IN", "MY", "AF"]; // a list of countries

const contactDetails = validateContactNumber(
  validLandlineNumber,
  countryISOList
);
// conatctDetails: {valid: true, countryISO: "IN", contactNumber: "2212345678", dialCode: "+91", countryName: "India", contactType: "landline" }

// pattern not satisfied
const validLandlineNumber = "+91 22 1234 5678"; // same goes for 9876543210
const countryISOList = ["SG", "MY", "AF"]; // a list of countries
const contactDetails = validateContactNumber(validLandlineNumber, countryISO);
// conatctDetails: {valid: false }

formatContactNumber,

Returns a number in a specified format. Function accepts contactNumber and contactFormat as required arguments. The formats can be given in patterns of d. Examples:

Example:

import { formatContactNumber } from "validate-contact-number";
const contactNumber = "9876543210";

console.log(formatContactNumber(contactNumber, "+91dddddddddd")); // +919876543210
console.log(formatContactNumber(contactNumber, "+91-dd-dddd-dddd")); // +91-98-7654-3210
console.log(formatContactNumber(contactNumber, "dd dddd dddd")); // 98 7654 3210
console.log(formatContactNumber(contactNumber, "dd dddd-dddd dd.dd")); // 98 7654-3210
