Kosovo Phone Validator

A JavaScript utility to validate and normalize Kosovo phone numbers in a compact format. This library ensures that phone numbers follow the correct format and are valid based on Kosovo's phone number standards.

General Idea

The kosovo-phone-validator library provides a function to validate Kosovo phone numbers. It ensures that the input number:

• Is in the correct format (with spaces).
• Starts with the Kosovo country code (+383).
• Contains a valid mobile or landline prefix.
• Contains only valid digits or a leading "+".

It removes all non-numeric characters (except spaces or the leading +) and validates the number according to the format used in Kosovo.

Key Features

• Format Validation: Ensures that the phone number contains only valid digits or a single + sign at the beginning.
• Prefix Validation: Validates mobile and landline prefixes based on Kosovo's telecommunication standards.
  • Mobile: Valid prefixes are 44, 45, 49, 43, 48, 47, 46.
  • Landline: Valid prefixes include 38, 28, 39, 290, 280, 29.
• Length Check: Checks that the length of the local number (excluding the country code) is appropriate:
  • For mobile numbers: 8 digits.
  • For landline numbers: 8 or 9 digits.
• Whitespace Handling: Automatically removes spaces between digits for validation, but spaces are allowed in the input (e.g., +383 44 555 333 is valid).
• No Dashes Allowed: Does not allow dashes in the number (e.g., +383-44-555-123 is invalid).

Installation

To install the library via npm:

npm install kosovo-phone-validator

Usage Example

Here’s a simple example of how to use the kosovo-phone-validator library:

import validateKosovoNumber from "kosovo-phone-validator";

// Example phone numbers
const phone1 = "+383 44 555 123"; // Valid mobile number
const phone2 = "+383 28 555 123"; // Valid landline number
const phone3 = "383 44 555 134"; // Invalid (missing + sign)
const phone4 = "+383 45 555 12345"; // Invalid (too long)

// Validate phone numbers
console.log(validateKosovoNumber(phone1)); // true
console.log(validateKosovoNumber(phone2)); // true
console.log(validateKosovoNumber(phone3)); // false
console.log(validateKosovoNumber(phone4)); // false
