Zip Code Database
If you want to use more countries or states than are listed in Lodgit Desk by default, you have the option to download the zip code database from GeoNames.org and integrate it into Lodgit Desk. This will automatically add all states to a country. Also, when entering a zip code and country, this database will automatically suggest a city that corresponds to this zip code.
To download this database go to Administration > Additional Modules > Install Zip Code Database…
In the new window, press Install. After the download and installation, the database will be available to you right away.
