Long story short, one of the retired iPhone 5 that my parents had laying around got adopted by a family friend. Today I was told that when the person makes a phone call to anyone it still shows up under my dad's name. ? No iCloud was on it, no sim card, and I completely reset it to factory settings. I don't know what's going on with this unless the serial number is registered to AT&T for his account or something weird like that, but I've never heard of it happening. On top of that, who has a caller ID anymore?
