How to check the MacBook Pro for authenticity?

Question

macbook

Hello dear!) I buy my first MacBook Pro 16 through an online store. I wanted to check for authenticity by the serial number that I was told in the store, but for some reason it does not work. I check on the website of Apple itself https://checkcoverage.apple.com/ru/ru/ , but he writes to me "Unfortunately, this serial number is invalid. Please check the available data and try again." The store explained that since the MacBook has not yet been activated, the serial number cannot be checked either. But on different sites they say that in this case information should have been displayed that the macbook has not yet been purchased. Are there those who bought a poppy and can tell the truth if they say in the store?

Answer 1

They write to you - invalid .
The store is giving you bullshit.

Answer 2

Of course, nonsense, he must find a photo of a MacBook, a model and write at least "Purchase date not confirmed."
