Invalid iPhone Serial Number, screen went black
My IMEI and Serial Number can be seen through my Apple ID. However, when I check it on http://checkcoverage.apple.com, it says it is invalid. My IPhone SE went black and does not restart. I am trying to contact apple support via chat and it asks for these numbers. When I enter it, it says it is invalid.
How do I resolve the issue?
