Macbook serial number beginning with an F

Please allow me to rephrase: Any reference to the letter “F” at the beginning of a serial does not denote refurbished status.

For the model numbers:

M = New

N = Replacement

P = Personalized

F = Refurbished

>>Any reference to the letter F at the beginning, would be for the model number, not the serial number. <<

That does not appear to be true. The serial number for my 13" MacBook Air M1 begins with FVF...

No, that is not an indication of a refurbished unit.

Any reference to the letter F at the beginning, would be for the model number, not the serial number.
