E164 international phone number normalizing, splitting, formatting.

Phony

The (admittedly crazy) goal of this Gem is to be able to format/split all phone numbers in the world.

Used in: airbnb.com, restorm.com, socialcam.com, zendesk.com (and many, many others).

There’s also a Rails wrapper: https://github.com/joost/phony_rails.

Description

This gem normalizes, formats and splits E164 phone numbers. A valid E164 phone number must include a country code.

E164 numbers are international numbers with a country dial prefix, usually an area code and a subscriber number. For example, the Austalian number number +61 412 345 678 can be broken down into the following components:

  • a country code of 61
  • a mobile number denoted by the 4 (specific to Australia)
  • a subscriber number of 12 345 678

Learn more about E164 numbers here.

Currently handles Abhas, Afghan, Algerian, Argentinan, Austrian, Australian, Azerbaijani, Belgian, Brazilian, Cambodian, Chilean, Chinese, Croatian, Cuban, Cypriot, Czech, Danish, Dutch, Egyptian, El Salvadorian, Estonian, French, German, Ghanan, Gibraltar, Greek, Haiti, Hong Kong, Hungarian, Indian, Iran, Irish, Israel, Italian, Kazakh, Lithuanian, Luxembourgian, Malaysian, Malta, Mexican, Monaco, Morocco, New Zealand, Nigerian, Norwegian, Peruvian, Polish, Romanian, Russian, Rwandan, Seychelles, Singapore, Slovakian, South African, South Korean, South Osetian, Spanish, Sri Lankan, Sudan, Swedish, Swiss, Thailand, Tunisian, Turkish, Liechtenstein, UK, US, Venezuelan, and Vietnamese numbers.

And to some extent, all others. Just try if it works for you.

If it doesn’t, please enter an issue.

Installation

Using with Rails? Check out: https://github.com/joost/phony_rails.

With Bundler:
Append gem 'phony' to your Gemfile and bundle install it.

Without Bundler:
Run gem install phony from your command line.

Usage

Plausibility

“Plausible” means “seems reasonable or probable”, not implying 100% correctness on a true, but implying 100% correctness on a false return value. So if this returns true, it might still be not a plausible number. If it returns false, it is definitely not an E164 conform number.

Use this method in combination with normalize for saving it into the database. Also see https://github.com/floere/phony/issues/35 for a discussion on the topic.

Note that you can add constraints to the plausibility check like the country code, cc, and the national destination code, ndc. Use the options to further limit the plausibility range. For example, only allow a small number of countries.

Phony.plausible?('0000000').should be_false

Phony.plausible?('hello').should be_false

Phony.plausible?('+41 44 111 22 33').should be_true

Phony.plausible?('+41 44 111 22 33', cc: '41').should be_true

Phony.plausible?('+41 44 111 22 33', ndc: '44').should be_true

Phony.plausible?('+41 44 111 22 33', cc: '1').should be_false

Phony.plausible?('+41 44 111 22 33', ndc: '43').should be_false

Phony.plausible?('+41 44 111 22 33', cc: '41', ndc: '44').should be_true

Phony.plausible?('+41 44 111 22 33', cc: /4(0|2)/, ndc: /4(4|5)/).should be_false

Phony.plausible?('+41 44 111 22 33', cc: /4(0|1)/, ndc: /4(4|5)/).should be_true

Normalizing

This will often raise an error if you try normalizing a non E164-izable number (a number that does not contain enough information to be normalized into an E164 conform number). Use Phony.plausible? for checking if it can be normalized first.

Phony.normalize('41443643533').should == '41443643533'

Phony.normalize('+41 44 364 35 33').should == '41443643533'

Note: There is also a ! version of each of these methods which
will destroy the original string and return a new (or old) one.
Just work only with the returned value, and you will be fine.
