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.

You can't track a phone based on its phone number. If another person has chosen to share their location with you in Maps then you can see it but there's no way to track someone without them knowing, for obvious reasons.

Tap on a place marker. At the bottom, tap the place name or address. Scroll and select the photo labeled "Street View."
