Formatting, storing and validating international phone numbers

Google's common Java, C++ and JavaScript library for parsing, formatting, storing and validating international phone numbers. The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich).

Main Features

  • Parsing/formatting/validating phone numbers for all countries/regions of the world.
  • getNumberType - gets the type of the number based on the number itself; able to distinguish Fixed-line, Mobile, Toll-free, Premium Rate, Shared Cost, VoIP and Personal Numbers (whenever feasible).
  • isNumberMatch - gets a confidence level on whether two numbers could be the same.
  • getExampleNumber/getExampleNumberByType - provides valid example numbers for all countries/regions, with the option of specifying which type of example phone number is needed.
  • isPossibleNumber - quickly guessing whether a number is a possible phonenumber by using only the length information, much faster than a full validation.
  • isValidNumber - full validation of a phone number for a region using length and prefix information.
  • AsYouTypeFormatter - formats phone numbers on-the-fly when users enter each digit.
  • findNumbers - finds numbers in text input.
  • PhoneNumberOfflineGeocoder - provides geographical information related to a phone number.
  • PhoneNumberToCarrierMapper - provides carrier information related to a phone number.
