Phone Number information lookup, validation, carrier name, geo and timezone infos

Verify phone number, validate format, checking carrier name, geo and timezone infos.

This library includes phone number lookup and validation, and the geocoding, carrier mapping and timezone mapping functionalities that are available in some of googles libphonenumber libraries.

To reduce the amount of data that needs to be loaded to geocode / carrier map a phone-number for each mapping only the relevant number prefixes are loaded from a binary json file (BSON). When the prefix could not be found in the provided locale the library tries to fall back to en as locale.

The library supports Node.js only at the moment.
