A Developer's Guide to the Phone Number Validator

The Phone Number Validator is a powerful tool for developers and anyone who needs to verify and format international phone numbers. It uses Google's libphonenumber-js library, the gold standard for phone number parsing, to provide accurate and detailed validation results.

Features

  • International Validation: Correctly validates phone numbers from almost every country in the world.
  • Format-Agnostic Input: You can enter a number in local format, international format (with +), or with spaces and hyphens—the tool will parse it correctly.
  • Detailed Information: For a valid number, the tool provides a wealth of information:
    • Validity and Possibility: Checks if a number is both possible (matches a valid pattern) and valid (a real, assigned number range).
    • Country Identification: Automatically detects the country the number belongs to.
    • Number Type: Identifies the number as MOBILE, FIXED_LINE, VOIP, etc.
    • Formatted Output: Displays the number in standard international format.
    • Dial URI: Provides a tel: link for easy dialing.
  • Country-Specific Context: You can provide a default country to help the validator correctly parse numbers that don't include a country code.

How to Use

  1. Enter a Phone Number: Type or paste the phone number you want to validate into the input field. It's best to use the international format (e.g., +12133734253) for the most accurate results.
  2. Select a Country: Choose the country associated with the number from the searchable dropdown. This helps the tool parse numbers written in a local format.
  3. Click Validate: Press the "Validate" button.
  4. Review the Results:
    • An alert will immediately tell you if the number is Valid or Invalid.
    • A series of cards will display detailed information about the number, including its type, country, and various formats.
