All you have to do is type "Where is my phone" in Google Chrome while logged into your Google account (or visit https://www.google.com/android/find/) to bring up the Find My Device map. A blue icon appears on the map, showing either the exact location or approximate area of your phone's last signal.

All you need is a device with a web browser and an active internet connection. Visit the Google Find My Device website. Sign in to your primary Google account. Click the lost phone in the upper-left corner. A Google Map appears, showing where your Android smartphone is located.
