Phonelib is a gem allowing you to validate phone number. All validations are based on Google libphonenumber. Currently it can make basic validations and formatting to e164 international number format and national number format with prefix. But it still doesn’t include all Google’s library functionality.
RDoc documentation can be found here rubydoc.info/gems/phonelib/frames

You can see an example of ActiveRecord validation by phonelib working in test/dummy application of this gem
Phonelib was written and tested on Rails >= 3.1. You can install it by adding in to your Gemfile with:
gem 'phonelib'
Run the bundle command to install it.
To set the default country (country names are ISO 3166-1 Alpha-2 codes), create a initializer in config/initializers/phonelib.rb:
Phonelib.default_country = "CN"
This gem adds validator for active record. Basic usage:
validates :attribute, phone: true
This will enable Phonelib validator for field “attribute”. This validator checks that passed value is valid phone number. Please note that passing blank value also fails.
Additional options:
validates :attribute, phone: { possible: true, allow_blank: true, types: [:voip, :mobile] }
possible: true - enables validation to check whether the passed number is a possible phone number (not strict check). Refer to Google libphonenumber for more information on it.
allow_blank: true - when no value passed then validation passes
types: :mobile or types: [:voip, :mobile] - allows to validate against specific phone types patterns, if mixed with possible will check if number is possible for specified type
To check if phone number is valid simply run:
Phonelib.valid?('123456789') # returns true or false
Additional methods:
Phonelib.valid? '123456789' # checks if passed value is valid number Phonelib.invalid? '123456789' # checks if passed value is invalid number Phonelib.possible? '123456789' # checks if passed value is possible number Phonelib.impossible? '123456789' # checks if passed value is impossible number
There is also option to check if provided phone is valid for specified country. Country should be specified as two letters country code (like “US” for United States). Country can be specified as String 'US' or 'us' as well as symbol :us.
Phonelib.valid_for_country? '123456789', 'XX' # checks if passed value is valid number for specified country Phonelib.invalid_for_country? '123456789', 'XX' # checks if passed value is invalid number for specified country
Additionally you can run:
phone = Phonelib.parse('123456789')
Returned value is object of Phonelib::Phone class which have following methods:
# basic validation methods phone.valid? phone.invalid? phone.possible? phone.impossible? # validations for countries phone.valid_for_country? 'XX' phone.invalid_for_country? 'XX'
You can also fetch matched valid phone types
phone.types # returns array of all valid types phone.type # returns first element from array of all valid types phone.possible_types # returns array of all possible types
Possible types:
-
:premium_rate- Premium Rate -
:toll_free- Toll Free -
:shared_cost- Shared Cost -
:voip- VoIP -
:personal_number- Personal Number -
:pager- Pager -
:uan- UAN -
:voicemail- VoiceMail -
:fixed_line- Fixed Line -
:mobile- Mobile -
:fixed_or_mobile- Fixed Line or Mobile (if both mobile and fixed pattern matches)
Or you can get human representation of matched types
phone.human_types # return array of human representations of valid types phone.human_type # return human representation of first valid type
Also you can fetch all matched countries
phone.countries # returns array of all matched countries phone.country # returns first element from array of all matched countries phone.country_code # returns country phone prefix
Also it is possible to get formatted phone number
phone.international # returns formatted e164 international phone number phone.national # returns formatted national number with country prefix
You can get E164 formatted number
phone.e164 # returns number in E164 format
There is extended data available for numbers. It will return nil in case there is no data or phone is impossible. Can return array of values in case there are some results for specified number
phone.geo_name # returns geo name of parsed phone phone.timezone # returns timezone name of parsed phone phone.carrier # returns carrier name of parsed phone
Phone class has following attributes
phone.original # string that was passed as phone number phone.sanitized # sanitized phone number (only digits left)
Gem includes data from Google libphonenumber which has regex patterns for validations. Valid patterns are more specific to phone type and country. Possible patterns as usual are patterns with number of digits in number.
Everyone can do whatever he wants, the only limit is your imagination. Just don’t forget to write test before the pull request. In order to run test without Rails functionality simply use
bundle exec rake spec
If you want to run including Rails environment, you need to set BUNDLE_GEMFILE while running the spec task, for example:
BUNDLE_GEMFILE=gemfiles/Gemfile.rails-3.2.x bundle exec rake spec
Gemfiles can be found in gemfiles folder, there are gemfiles for Rails 3.1, 3.2 and 4.
