I lost my phone 6s and I want to get the location

Start here: If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

if you can get access to a Mac computer or another iPad or iPhone, sign into the “Find iPhone” (on iOS 11 and macOS Mojave and older) or “Find My” (on iOS 12 and macOS Catalina and newer) If you are able to login, you should see a list of your Apple devices, click the iPhone you are talking about, it will put a picture of your device on a map, and you can get directions to your device, which you can print out or use GPS (if available)
