Apple Planning Switch to Randomized Serial Numbers for Future Products Starting in 'Early 2021'
Found on MacRumors on Sunday, 28 March 2021
Apple's current serial number format has long allowed both customers and service providers to determine the date and location that a product was manufactured, with the first three characters representing the manufacturing location and the following two indicating the year and week of manufacture. The last four characters currently serve as a "configuration code," revealing a device's model, color, and storage capacity.
So much for transparency. That's one way to cover up the bad reputation it has with problems related to Foxconn.
