How Country Identification by International Phone Number Works
An international phone number consists of three main parts:
International prefix is marked with the + sign and indicates the international format of the number.
Country code from one to four digits uniquely identifies the country in the global telephone network.
National number contains the area code and subscriber number according to the standards of the specific country.
Our detector analyzes all components and provides complete information about the country, region, carrier, and validity of the number according to ITU-T standards.
