ZipCarton is a plugin for your Mac OS X Address Book that tries to find the ZIP or postal code for the city you entered in your contact's details.
ZipCarton is open source, completely free, and can find postcodes in 42 countries: Andorra, Australia, Austria, Bangladesh, Belgium, Bulgaria, Canada, Croatia, Czech Republic, Denmark, Greenland, Hungary, Iceland, India, Italy, Liechtenstein, Luxembourg,
ZipCarton will only replace the postal code if it finds a single match in the GeoNames postal code database.
