Where can I locate the Model Number for my iPod, iPhone, or iPad? Are Model Numbers unique? What are the limitations identifying a specific device using Model Numbers?
Apple Model Numbers -- which are available on the back of all iPod, iPhone and iPad models -- look like A1203 or M8541. As a bit of trivia, only the Original "Scroll Wheel" iPod has a Model Number that starts with an "M" and all other models start with an "A" followed by four digits. On some vintage G3 and G4-powered Macs, a Model Number that starts with an "M" is identified as a "Family Number," so it is possible to hear an "old school" Mac user refer to these numbers as Family Numbers for newer products as well.
For identification purposes, the advantage of Model Numbers is that they are on the hardware itself and are easy to locate on iPod, iPhone and iPad models -- on the back of the device near the bottom (or under the "clip" for applicable iPod shuffle and iPod nano models) -- and are also almost always unique to a particular model (some older "full-size" iPod models that are similar do share Model Numbers, however).

The disadvantages are that the print is so small it can be difficult for many to read and the Model Number is not available within software or in other documentation. More confusingly, even -- on iPod touch, iPhone and iPad models, which all run the iOS -- Apple refers to a different identifier as the "Model" as well. Elsewhere, the "Model" identifier listed in software is more commonly referred to as an Order Number.
For example, the 8 GB configuration of the iPod touch 4th Gen is identified as "Model No" A1367 on the back and "Model" MC540LL within the iOS. To make your life easier, though, Everyi.com's Ultimate iLookup is "smart enough" to track down this model using either identifier.
If you cannot find an iPod, iPhone or iPad using its Model Number, but are able to track it down using another identifier, please share any missing information with Everyi.com. Thank you.
