django-phonenumber-field

A Django library which interfaces with python-phonenumbers to validate, pretty print and convert phone numbers. python-phonenumbers is a port of Google's libphonenumber library, which powers Android's phone number handling.

Included are:

• PhoneNumber, a pythonic wrapper around python-phonenumbers' PhoneNumber class
• PhoneNumberField, a model field
• PhoneNumberField, a form field
• PhoneNumberField, a serializer field
• PhoneNumberPrefixWidget, a form widget for selecting a region code and entering a national number. Requires the Babel package be installed.
• PhoneNumberInternationalFallbackWidget, a form widget that uses national numbers unless an international number is entered. A PHONENUMBER_DEFAULT_REGION setting needs to be added to your Django settings in order to know which national number format to recognize.

Installation

pip install django-phonenumber-field[phonenumbers]

As an alternative to the phonenumbers package, it is possible to install the phonenumberslite package which has a lower memory footprint.

pip install django-phonenumber-field[phonenumberslite]

Basic usage

First, add phonenumber_field to the list of the installed apps in your settings.py file:

INSTALLED_APPS = [
    ...
    'phonenumber_field',
    ...
]

Then, you can use it like any regular model field:

from phonenumber_field.modelfields import PhoneNumberField

class MyModel(models.Model):
    name = models.CharField(max_length=255)
    phone_number = PhoneNumberField()
    fax_number = PhoneNumberField(blank=True)

Internally, PhoneNumberField is based upon CharField and by default represents the number as a string of an international phonenumber in the database (e.g '+41524204242').

The object returned is a PhoneNumber instance, not a string. If strings are used to initialize it, e.g. via MyModel(phone_number='+41524204242') or form handling, it has to be a phone number with country code.

Running tests

tox needs to be installed. To run the whole test matrix with the locally available Python interpreters and generate a combined coverage report:

tox

run a specific combination:

tox -e py310-djmain,py39-djmain
