I'd think there is probably some scam going on where people somehow scam Apple by providing serial numbers for devices that they don't own. With this change, it should be impossible to figure out the serial number of an existing device unless you have that device in your hands. So a repair shop cannot charge Apple for replacing a motherboard under warranty for a device that was never in the repair shop.
I brought this to Apple’s attention a few years ago.
When I suggested it, I also asked for a free lookup tool and API, but more importantly, getting rid of at least some of the redundant identifiers Apple uses. Let’s see if they do that too.
The point is that when it comes to identifying assets of a company, school or for insurance, the Apple Model Number (A-Number) was/is absolutely useless.
Instead, I suggested something similar to what Boeing does when they build an airplane. For example, they have a 787, and the next 3 digits are an “Effectivity number”; signifying what changes are made to the airframe, such as type of engine, fuel capacity on wings, space dedicated to passengers (vs luggage/freight) and changes required at
the factory.
A 737-800 is different than a 737-500 for example, but both airplanes share a good deal of technology related to the the airframe.
To identify “as flying” condition, the airplane also gets a “Tail-Number” which is what is used to lookupmanage maintainence logs, ownership/leasing information for things like recalls, and other maintainence items which are often electronic now.
I then pointed to Dell and their “Service Number” option. A Dell 4300 with Service Number FYX2482 is also easier to read (and say) over the telephone. Dell often omits 0s, 5s and 1s as they can be mistaken as letters O S, and L as labels fade and laptops are scratched, causing rework on the phone during lookup.
The point is customers get confused all the time and the process involved with multiple models, sometimes defined by free form text field is terrible.
The A-Number was really a joke. It should’ve been rendered useless years ago when Apple started making laptops that even varied on chipsets, much less 32/64 bit processors.
That said however, the process of creating a completely new serial number should replace the useless A-Number which just adds overhead to companies who manage it. The free form text field of “MacBook Pro late 2025” is freaking nuts.
I also asked Apple to make the IMEI on an iphone a scannable barcode when you dial *#06#, something they implemented already.
If SN remained alphanumeric, had an online lookup tool, a short 4-digit A-Number could identify millions of devices uniquely, but I also suggested extending it to 8 characters for a check digit and randomization.
