mail address validation in python/django

Question

We are developing our website in django framework and with python. currently we are looking for an api/a tool to validate the physical addres the user enters. It doesn't need to be vey sophisticated. We just need to avoid spam registrations. For this step, we need to verify if country, state, city, and zipcode are belong to each other. For instance, Berkeley as a city with Zipcode 94704 is not in NY state, etc. Any thoughts?

You can give a try to pygeocoder. It's a Python wrapper for Google's Geocoding V3 API. It can fulfill some of your validation needs.

from pygeocoder import Geocoder
g = Geocoder()
g.geocode("1 wellington, ottawa").valid_address
>>> True
g.geocode("1 wellington, chicago").valid_address
>>> False

It can take some minor misspelling too

result = g.geocode("1600 amphiteather, mountain view")
result.valid_address
>>> True
print result
>>> 1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA
g.geocode("16000000 amphitheater, mountain view").valid_address
>>> False

But Google doesn't always have the right postal/zip code. USPS has a public API for the US I believe.
