What's the best way to store Phone number in Django models

User would enter a phone number

Answer 1

Use django-phonenumber-field: https://github.com/stefanfoulis/django-phonenumber-field

pip install django-phonenumber-field

Answer 2

It all depends in what you understand as phone number. Phone numbers are country specific. The localflavors packages for several countries contains their own "phone number field". So if you are ok being country specific you should take a look at localflavor package (class us.models.PhoneNumberField for US case, etc.)

Otherwise you could inspect the localflavors to get the maximun lenght for all countries. Localflavor also has forms fields you could use in conjunction with the country code to validate the phone number.
