When I logged in to support.apple.com and search for the nearest service provider, it said it is not possible, as I expected. My location services are turned off since Day 1. There is no particular reason, I just do not need that for the device in question. Only one device is added to the particular account, and I never really carry this device to anywhere.
I remember to have search up my zip code once (on the support website to get the nearest provider) which probably might be available to them (albeit unlikely), or they probably have the data because of the details provided by Apple Store from where I purchased it.
It freaks me out, since I do not see something that they see. Not because they have the details.
