where-calling-from

A lightweight JavaScript utility that detects the country of a phone number by checking its international calling code. Automatically removes spaces, symbols, and formatting before detection.

Features

• Cleans phone numbers from formatting symbols
• Detects country based on international calling code
• Includes data for 30 common countries
• Easy to extend by adding more codes
• Zero dependencies

Installation

npm install where-calling-from

Usage

CommonJS

const whereCallingFrom = require("where-calling-from");

whereCallingFrom("+1 (202) 555-0199");
// Output:
// The phone number :+12025550199 is from United States

More Examples

whereCallingFrom(" +212-653_889[441] ");
// The phone number :+212653889441 is from Morocco

whereCallingFrom(" 91-8877-554-321 ");
// The phone number :+918877554321 is from India

whereCallingFrom("999999999");
// There is no country for this number

How It Works

1. Sanitization

number.replaceAll(/[-_()\[\]{}+ ]/g, "");

2. Prefix Detection

num.startsWith(item.code)

3. Console Output

The result is printed directly to the console.

Country Code List

The internal data looks like this:

const data = [
  { country: "United States", code: "1" },
  { country: "Canada", code: "1" },
  { country: "United Kingdom", code: "44" },
  { country: "Germany", code: "49" },
  { country: "France", code: "33" },
  { country: "Italy", code: "39" },
  { country: "Spain", code: "34" },
  { country: "Australia", code: "61" },
  { country: "New Zealand", code: "64" },
  { country: "India", code: "91" },
  { country: "Pakistan", code: "92" },
  { country: "Bangladesh", code: "880" },
  { country: "China", code: "86" },
  { country: "Japan", code: "81" },
  { country: "South Korea", code: "82" },
  { country: "Russia", code: "7" },
  { country: "Ukraine", code: "380" },
  { country: "Egypt", code: "20" },
  { country: "South Africa", code: "27" },
  { country: "Nigeria", code: "234" },
  { country: "Kenya", code: "254" },
  { country: "Morocco", code: "212" },
  { country: "Saudi Arabia", code: "966" },
  { country: "United Arab Emirates", code: "971" },
  { country: "Turkey", code: "90" },
  { country: "Brazil", code: "55" },
  { country: "Argentina", code: "54" },
  { country: "Mexico", code: "52" },
  { country: "Chile", code: "56" },
  { country: "Colombia", code: "57" }
];

Extending the List

You can add new countries easily:

data.push({ country: "Tunisia", code: "216" });

Roadmap

• Return structured results instead of console logging
• Longest-prefix matching
• TypeScript definitions
• Support for full global calling code database
