phonenumbers

This is actually a port of Google's libphonenumber Java, C++ and JS library.

As the original, the phonenumbers library can parse, format, store and validate both national and international telephone number formats.

It also works practically the same, allowing developers to easily port their Java, JS, or C++ code to Python if needed.

phonenumbers is ideal for developing mobile apps, but it also works with desktop or Web software, coming with support for all major OS platforms.
