Store Locator Plus uses the built-in WordPress internationalization and localization tools to translate the interface text into various languages. Store Locator Plus plug-in is part of the WordPress Translate project. You can contribute translations for the base plugin at the Store Locator Plus directory at WordPress Translate.
If you do not see the base plugin in your language, check the SLP Translate report for the latest Stable Release and make sure your language is at 100%. The Translate system will not create a language export for partial translations. If you want to help with the translation, send a request to be added to the WordPress PolyGlots project.

The following countries are currently supported in the Store Locator Plus plugin. These countries determine the default center starting point for location searches and determine which Google locations engine is used when searching for an address. This influences, but does not restrict, which results are returned. Regardless of what country you select as the default, any location in your location database can be returned by the search regardless of the country in which that location resides. This does not effect the zip codes necessarily. Some country postal codes are unique, others are not.
The Store Locator Plus plugin is now part of the WordPress Translate project. You can get the current status of the Store Locator Plus translations on the WordPress Translation website. If you would like to see the plugin fully translated into your language, please send a request to be added to the WordPress translate team for your language. As soon as a language reaches 100% completion for the stable release of the Store Locator Plus plugin, the custom language files will be removed from Store Locator Plus and be replaced by the more-efficient Translate system.
