About this Phone Number Formatter
Built on Google's libphonenumber metadata — the same library behind Android's dialler — this tool detects the country, validates length and prefix rules, identifies mobile vs landline, and outputs every standard format. E.164 (+919876543210) is the format APIs, SMS gateways and databases expect.
