Be specific: what is the number refering to? I remember seeing in several photos of the F40 assembly line, sequential numbers written on tape, applied to the door-jam. Obviously, when the car was finished, the number was removed.
I also know of some coachbuilders who numbered the bodies and related parts with a matching number. A number completely different than the chassis number.
