If someone's address is in your Google Contacts, you can find their address on the map by searching for their name. If you search for an address, you can see any contacts matching that address.

To track a phone number using Google Maps, first ensure that the phone's GPS is turned on. Then, add the phone number to your Google contacts and use Google Maps' 'Share Location' feature to request access to their location. Once they've accepted your request, you can monitor their location on your device.

On your computer, open Google Maps and make sure you're signed in. Search for a contact's name or address. Matching contacts will appear in the suggestions. To see your contact on the map, choose a name or address.
