phonenumbers Python Library

This is a Python port of libphonenumber, originally from: http://code.google.com/p/libphonenumber/.

Original Java code is Copyright (C) 2009-2011 The Libphonenumber Authors

Example Usage

The main object that the library deals with is a PhoneNumber object. You can create this from a string representing a phone number using the parse function, but you normally also need to specify the country that the phone number is from (unless the number is in E.164 format).

>>> import phonenumbers
>>> x = phonenumbers.parse("+442083661177", None)
>>> print x
Country Code: 44 National Number: 2083661177 Leading Zero: False
>>> type(x)
<class 'phonenumbers.phonenumber.PhoneNumber'>
>>> y = phonenumbers.parse("020 8366 1177", "GB")
>>> print y
Country Code: 44 National Number: 2083661177 Leading Zero: False
>>> x == y
True

Once you've got a phone number, a common task is to format it in a standardized format. There are a few formats available (under PhoneNumberFormat), and the format_number function does the formatting.

>>> phonenumbers.format_number(x, phonenumbers.PhoneNumberFormat.NATIONAL)
u'020 8366 1177'
>>> phonenumbers.format_number(x, phonenumbers.PhoneNumberFormat.INTERNATIONAL)
u'+44 20 8366 1177'
>>> phonenumbers.format_number(x, phonenumbers.PhoneNumberFormat.E164)
u'+442083661177'

If your application has a UI that allows the user to type in a phone number, it's nice to get the formatting applied as the user types. The AsYouTypeFormatter object allows this.

>>> formatter = phonenumbers.AsYouTypeFormatter("US")
>>> print formatter.input_digit("6")
6
>>> print formatter.input_digit("5")
65
>>> print formatter.input_digit("0")
(650
>>> print formatter.input_digit("2")
(650) 2
>>> print formatter.input_digit("5")
(650) 25
>>> print formatter.input_digit("3")
(650) 253
>>> print formatter.input_digit("2")
650-2532
>>> print formatter.input_digit("2")
(650) 253-22
>>> print formatter.input_digit("2")
(650) 253-222
>>> print formatter.input_digit("2")
(650) 253-2222

Sometimes, you've got a larger block of text that may or may not have some phone numbers inside it. For this, the PhoneNumberMatcher object provides the relevant functionality; you can iterate over it to retrieve a sequence of PhoneNumberMatch objects. Each of these match objects holds a PhoneNumber object together with information about where the match occurred in the original string.

>>> text = "Call me at 510-748-8230 if it's before 9:30, or on 703-4800500 after 10am."
>>> for match in phonenumbers.PhoneNumberMatcher(text, "US"):
...     print match
...
PhoneNumberMatch [11,23) 510-748-8230
PhoneNumberMatch [51,62) 703-4800500
>>> for match in phonenumbers.PhoneNumberMatcher(text, "US"):
...     print phonenumbers.format_number(match.number, phonenumbers.PhoneNumberFormat.E164)
...
+15107488230
+17034800500

Finally, you might want to get some information about the location that corresponds to a phone number. The geocoder.area_description_for_number does this, when possible.

>>> from phonenumbers.geocoder import area_description_for_number
>>> ch_number = phonenumbers.parse("0431234567", "CH")
>>> print repr(area_description_for_number(ch_number, "de"))
u'Z\\xfcrich'
>>> print repr(area_description_for_number(ch_number, "en"))
u'Zurich'
>>> print repr(area_description_for_number(ch_number, "fr"))
u'Zurich'
>>> print repr(area_description_for_number(ch_number, "it"))
u'Zurigo'

For more information about the other functionality available from the library, look in the unit tests or in the original libphonenumber project.

Project Layout

  • The python/ directory holds the Python code.
  • The resources/ directory is a copy of the resources/ directory from libphonenumber. This is not needed to run the Python code, but is needed when upstream changes to the master XML metadata need to be incorporated.
Something went wrong with that request. Please try again.
