SSID / BSSID is often enough to pinpoint the location of someone. Recently someone debated this with me, so I asked him what his wifi AP name was, then proceeded to provide their home address. How? By searching it in https://wigle.net. That ended the debate quite swiftly. - Source: Hacker News / 5 months ago

IP gives you a rough location (like which city at best), SSID/BSSID can give you street/building level accuracy if it's in a database like https://wigle.net Considering the scale of these apps, I'm guessing they have internal wifi<->location databases with fairly great accuracy. - Source: Hacker News / 5 months ago

There are also wardriving databases (like wigle.net) that have information about Wi-Fi networks detected by wardrivers all around the globe which may includes yours. Source: 6 months ago

You can use a site like https://wigle.net/ and type in wifi SSIDs and use it to potentially locate your whereabouts. Source: 11 months ago

This sounds like manual wardriving and a lot of unnecessary work. Check out Wigle and you might be able to find the answers you're looking for or you can download their app and contribute. Source: 11 months ago
