Client-side resolution for acquiring the user's dialing code enables seamless phone number input within browsers, and this library is also compatible with Node.js!

Using npm:

npm install guess-calling-code

Using yarn:

yarn add guess-calling-code

This library can be used in both browser and Node.js environments.

First, include the library in your HTML file:

<script src="https://cdn.jsdelivr.net/npm/guess-calling-code/dist/index.umd.js"></script>

Then, in your JavaScript code:

const guessCallingCode = window.guessCallingCode;
const callingCode = guessCallingCode(); // example output: "1" (for United States users)

npm install guess-calling-code

or

yarn add guess-calling-code

Then, in your JavaScript code:

const guessCallingCode = require("guess-calling-code");
const callingCode = guessCallingCode(); // example output: "1" (for United States users)

import guessCallingCode from "guess-calling-code";
const callingCode = guessCallingCode(); // example output: "1" (for United States users)

This function returns the calling code as a string based on the user's current time zone city.
