Available Databases




Postal Code Database This Canadian postal code database is fairly complete. We've had reports of a missing postal code now and then but it still does the job quite well.
Zip Code Database This United States zip code database is a few years old but still works well for me. We originally created it to auto-populate city, county, state information based on zip code. Almost all ZIP codes have lon/lat values associated with them but some ZIP codes do not. Most of those are military zip codes.
IP Address/Country Database Free IP address to country database (from MaxMind) which allows you to determine which country an IP address belongs to.
IP Address/City Database Free IP address to city database (from MaxMind) which allows you to determine country, state/region, city, US postal code, US area code, metro code, latitude, and longitude information for IP addresses worldwide.
