How does it work?

This tool uses libphonenumber-js, a lightweight port of Google's libphonenumber library, running entirely in your browser via WebAssembly. It parses the phone number according to international standards, validates it against the country's numbering plan, and formats it in E.164, international and national formats. No data is ever sent to our servers.
