Is it possible to check the serial number to see if the receiver and the controller are the original combination at factory?

Is it possible to check the serial number to see if the receiver and the controller are the original combination at factory?

because now im suspecting my herelink air unit is changed with someone else.

on my box SN : HX4-06071-9800372
on air unit SN : HX4-06074-9800283
on transmitter SN : HX4-06075-9800274

my local reseller said they couldn’t check it but i ask here again.

Just asking why does it bother you? They can pair anyway no matter they are original pair or not.
