At what point a Macbook gets a serial number?

[tadziak]

Hi,
I was wondering if anybody knows, at what point a Macbook receives a serial number? Is it already during manufacturing or a bit after?

If have two almost identical serial numbers (one letter difference) on my two devices, does it mean they were built one after another - let's say within 15 minutes periond?

Or maybe the real serial numbers are given a bit later, before the computers are boxed?

theyre serialized during the final process of manufacturing. alot of them are very similar, but doesnt necessarily mean they were made right after each other. im sure theres a specific algorithm that creates the serial numbers.

Appleserial info claims that:
Mac nr 1 - This unit was number 1169 to be built that week.
Mac nr 2 - This unit was number 1168 to be built that week.

Wonder how accurate is that website about such things.
