Is there any Python module that helps with US and foreign zip-code

often used for basic user-registration, I'm assuming functionality of
this sort must be available for Python. Any suggestions will be much
appreciated.
There might be an associated can of worms here, for example in the
Netherlands zip codes are actually copyrighted and require a license if
you want to do something with them, on the other hand you get a nice SQL
formatted db to use it. I don't know how this works in other countries
but I imagine that it is likely to be generally the same.
Also in The Netherlands, ZIP codes are much more fine-grained than in
some other countries: ZIP code plus house number together are sufficient
to uniquely identify an address. I.e. you don't need the street name.
E.g., my work address has ZIP code 1098 XG and house number 123, so
together they indicate that I work at Science Park 123, Amsterdam.
In other words, a simple city <-> ZIP mapping is not sufficient.
The same comment applies to UK postcodes, which are also alphanumeric.
My home postcode, for example, is shared with only 3 other houses, IIRC.
