Google Maps has a wide array of tools to help you explore the world, but keep in mind that these tools may not be available for all regions. Check out the links below to see where these features are available.
Take a look at this list of countries and regions that you can edit using Google Map Maker.
Visit the Google Places homepage and click on the Country drop-down menu to see where this is available. In countries where listings can't be added using Google Places, you may be able to add these locations using Map Maker.
In some areas, you can edit business listing details using the Edit details link, which can be found in the drop-down menu from the information window.
In other areas, you can move the marker of a location, but you can't edit any business details.
