Elixir library for parsing, formatting, and validating international phone numbers.
Based on Google's [libphonenumber](https://github.com/googlei18n/libphonenumber).

**Current metadata version: v8.13.8.**

## Installation

Add `:ex_phone_number` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:ex_phone_number, "~> 0.4"}
  ]
end
```

## Usage

```elixir
iex> {:ok, phone_number} = ExPhoneNumber.parse("044 668 18 00", "CH")
{:ok,
 %ExPhoneNumber.Model.PhoneNumber{
   country_code: 41,
   country_code_source: nil,
   extension: nil,
   italian_leading_zero: nil,
   national_number: 446681800,
   number_of_leading_zeros: nil,
   preferred_domestic_carrier_code: nil,
   raw_input: nil
}}

iex> ExPhoneNumber.is_possible_number?(phone_number)
true

iex> ExPhoneNumber.is_valid_number?(phone_number)
true

iex> ExPhoneNumber.get_number_type(phone_number)
:fixed_line

iex> ExPhoneNumber.format(phone_number, :national)
"044 668 18 00"

iex> ExPhoneNumber.format(phone_number, :international)
"+41 44 668 18 00"

iex> ExPhoneNumber.format(phone_number, :e164)
"+41446681800"

iex> ExPhoneNumber.format(phone_number, :rfc3966)
"tel:+41-44-668-18-00"
```

## E164 Formatted Numbers

In E164 formatted numbers the country code can be detected. So you can pass them in to `ExPhoneNumber.parse/2` with `""` or `nil` as the second argument.

```elixir
iex> ExPhoneNumber.parse("+977123456789", "")
{:ok,
 %ExPhoneNumber.Model.PhoneNumber{
   country_code: 977,
   country_code_source: nil,
   extension: nil,
   italian_leading_zero: nil,
   national_number: 123456789,
   number_of_leading_zeros: nil,
   preferred_domestic_carrier_code: nil,
   raw_input: nil
 }}
```

## Development

There is a `mix update_metadata` task that downloads the latest `libphonenumber` metadata.
