The serial number on the cover is different from the one under "about this Mac". should I be worried? At one point on my iphone under Apple ID it showed two MacBook Air's logged onto my ID. I removed the one that didn't match the cover and that was before I noticed the different numbers.
MacBook Air 13″, macOS 12.4
Another possibility is that the logic board was replaced at some point. The replacement would have a different serial number and the tech is supposed to register the new one with Apple. I had that happen once; Apple had the technician come back (this was a repair at home) and register it properly. So, I would contact Apple and check on it.

Where did you buy the Mac? I'd be worried it was stolen, but then I'm a naturally suspicious sort of guy.
I bought it from Istore over 5 years ago and I just noticed it today after I suspected a possible hack on my device.
That old I'd not worry about it.
Is it possible for 1 macbook air to have two different serial number?
