What can not be sent on the Internet by technology?

Question

Information Security

Although online for a long time, but recently I almost sent all my card details to scammers who introduced themselves as bank employees, how many times I heard that they didn’t send, but somehow there was a stressful situation and I wanted to quickly solve the problem, since I couldn’t remember all the data , and then it dawned on me to check who I'm talking to. Since then, paranoia has been notable.
Now you need to buy something on the Internet for a laptop and phone, and the seller asks for photos of stickers, insides, etc., i.e. where are different serial numbers, codes for Windows, etc. As I remember, Asus can register devices or something like that. I understand that the seller most likely wants to understand as much as possible what I need, and not what I want to buy, but still ...
Q: Is there any data that should not be reported? laptop serial numbers? Phone IMEI? or something else?

Answer 1

Part numbers and serials and model names are available. But the serial number is usually of no help, and for some devices the serial number is a password. So if you are paranoid, then do not send anything except the name and model.

Answer 2

IMEI is definitely not worth it. Serials - only in support.
