Finding the Serial Number of a previously paired device (windows/ios)

I think someone took my bluetooth headphones. I live in a student accommodation - and I've tried walking around and picking up the different Bluetooth devices in the flats. Most devices only show the serial number, and not the name. I was wondering if it was possible to pull the serial number for windows or IOS (the device has been paired with my laptop and my phone). Thanks
