C# port of Google's libphonenumber library.

The code was rewritten from the Java source mostly unchanged, please refer to the original documentation for sample code and API documentation.

The original Apache License 2.0 was preserved.

See this for details about the port.

Phone number metadata is updated in the Google repo approximately every two weeks. This library is automatically updated by a scheduled github action to include the latest metadata, usually within a day.

Run the following command to add this library to your project

dotnet add package libphonenumber-csharp

Available on NuGet as package libphonenumber-csharp.

using PhoneNumbers;

var phoneNumberUtil = PhoneNumberUtil.GetInstance();
var e164PhoneNumber = "+44 117 496 0123";
var nationalPhoneNumber = "2024561111";
var smsShortNumber = "83835";
var phoneNumber = phoneNumberUtil.Parse(e164PhoneNumber, null);
phoneNumber = phoneNumberUtil.Parse(nationalPhoneNumber, "US");
phoneNumber = phoneNumberUtil.Parse(smsShortNumber, "US");

using PhoneNumbers;

var phoneNumberUtil = PhoneNumberUtil.GetInstance();
var phoneNumber = phoneNumberUtil.Parse("+14156667777", "US");
var formattedPhoneNumber = phoneNumberUtil.Format(phoneNumber, PhoneNumberFormat.INTERNATIONAL);
var formattedPhoneNumberNational = phoneNumberUtil.Format(phoneNumber, PhoneNumberFormat.NATIONAL);

Console.WriteLine(formattedPhoneNumber.ToString()); // +1 415-666-7777
Console.WriteLine(formattedPhoneNumberNational.ToString()); // (415) 666-7777

using PhoneNumbers;

var phoneNumberUtil = PhoneNumberUtil.GetInstance();
var phoneNumber = phoneNumberUtil.Parse("+14156667777", "US");
var isValid = phoneNumberUtil.IsValidNumber(phoneNumber);

Console.WriteLine(isValid); // true

using PhoneNumbers;

var phoneNumberUtil = PhoneNumberUtil.GetInstance();
var phoneNumber = phoneNumberUtil.Parse("+14156667777", "US");
var numberType = phoneNumberUtil.GetNumberType(phoneNumber);

Console.WriteLine(numberType); // PhoneNumberType.FIXED_LINE_OR_MOBILE

See PhoneNumberType.cs for the various possible types of phone numbers

using PhoneNumbers;

var phoneNumberUtil = PhoneNumberUtil.GetInstance();
var phoneNumber = phoneNumberUtil.Parse("+14156667777", null);
var regionCode = phoneNumberUtil.GetRegionCodeForNumber(phoneNumber);

Console.WriteLine(regionCode); // US

• 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 218 countries/regions, with the option of specifying which type of example phone number is needed.
• IsPossibleNumber - quickly guessing whether a number is a possible phone number by using only the length information, much faster than a full validation.
• AsYouTypeFormatter - formats phone numbers on-the-fly when users enter each digit.
• FindNumbers - finds numbers in text input

See PhoneNumberUtil.cs for the various methods and properties available.

• port read / write source xml data to binary for better performance and smaller .nupkg size (WIP)
• update / add / port new unit tests and logging from java source

• Install Jetbrains - Resharper for Visual Studio
• File by file, right click and "Cleanup code"
• Check the unfolded file

To run tests locally, you will need a zip version of the geocoding.zip file stored in the resources folder and testgeocoding.zip file stored in the resources/test folder.

On linux, you can run the following commands to generate the zip accordingly

(cd resources/geocoding; zip -r ../../resources/geocoding.zip *)
(cd resources/test/geocoding; zip -r ../../../resources/test/testgeocoding.zip *)

For windows, you can use the following powershell script

Compress-Archive -Path "resources\geocoding\*" -DestinationPath "resources\geocoding.zip"
Compress-Archive -Path "resources\test\geocoding\*" -DestinationPath "resources\test\testgeocoding.zip"
