Commercial packages and the USPS sell zip code programs and database that are over twice that large. I believe the CivicSpaceLabs zip code database comes out of the US Census Bureau. The 4GuysFromRolla article previously given gave a url to the Gazetterr which is broken - I think this is the correct url: http://www.census.gov/geo/www/gazetteer/gazette.html http://www.census.gov/tiger/tms/gazetteer/zips.txt http://www.census.gov/tiger/tms/gazetteer/zips.zip Maybe will will see a geo-tagging based ruby quiz in the future ... --------------------------------- Yahoo!
