How to Open a Dropped Pin on Android
If you're looking to save a new location you found in Google Maps, you'll need to drop a pin on the exact location. Doing so will help you to find it again. Here's how.
Drop a Pin in Google Maps on Windows or Mac
There are two ways to drop a pin on a location in Google Maps on your Windows 10 PC or Mac. You can use the search bar to drop a pin automatically, or you can drop a pin on any location on the map manually.
To start, open the Google Maps website and, if you want to save a location, you'll need to sign in to your account. To automatically drop a pin, search for a location using the search bar in the top-left corner.
Search suggestions will appear below the search bar—select one of these to drop a pin on that location.
An information panel will open on the left, offering you options to share or save the location, or to find directions to or from it. In the map view on the right, a red pin will drop on the same location, pinpointing it on the map for you to quickly identify.
You can also drop a pin manually. To do this, select any location in the map view. A smaller pin icon will appear on the map, with a quick directions box appearing at the bottom.
To view the larger red pin on that location (along with the information panel on the left), select the map coordinates in the quick directions box.
The red pin and information panel will appear at this point, allowing you to save or share the location. To remove the pin, select the cross icon on the search bar or select elsewhere on the map itself.
Drop a Pin in Google Maps on Android, iPhone, and iPad
If you're using the Google Maps app on Android, iPhone, or iPad, you can also drop a pin on any location using the search bar or map view.
To use the search bar, open the app and type a location into the search bar at the top. Tap one of the search suggestions that appear underneath to view that location.
A red pin will drop automatically on the location you've searched for, with a smaller information panel at the bottom. Tapping this information panel will bring up additional options and information, including directions, address and contact details, business reviews, and more.
If you want to drop a pin manually, move to the area on the map that you'd like to drop the pin on, then press and hold on that location using your finger.
After a few seconds, a red pin will appear at that location.
You can then save or share the location using the small information panel at the bottom, find directions, or more.
To remove the dropped pin, tap the "X" icon on the search bar. Alternatively, tap on any other location in the map view.
Red pins are temporary, so doing this will remove the pin from the map, allowing you to search for other locations.
