We have made available free Postal Code databases for Canada, Germany, Great Britain and Mexico. These files have most of the commonly used postal codes, but are not complete. We plan to make more countries available over time, as well as adding region name, latitude and longitude columns. Note the third column is the FIPS 10-4 region code.

Free Canadian Postal Codes
Free German Postal Codes
Free British Postal Codes
Free Mexican Postal Codes

Use of this data is subject to our Open Data License.

Free US postal code databases are also available, see: CivicSpace's US Zip Codes [download] and iBegin.com. The iBegin.com free postal code database seems to be reasonably complete and up to date.

Worldwide postal code databases can be found at Event Me's free postal code sources and downloads.
