Last time I looked, the way to go was to grab the TIGER dataset from the US
Census. The last update was in 1990, so it's somewhat out-of-date, but may
be good enough for your purposes. (Lots of commercial products are based on
this data, but they do their own updates). There's a Geo::TigerLine module
on CPAN that I'd take a look at, but the doc page says it's unfinished.
The data files give you a location (lat/long) for a street address range, so
actually doing the lookup should be trivial.
