Every product Apple sells carries three different codes, and they answer three different questions. The model number says which device this is, in the regulatory sense. It is an A followed by four digits, printed on the device itself, and shared by every unit of that model sold in a given set of countries. The part number says which exact configuration this is, down to the finish, the storage and the region it was sold in. The model identifier is the name the operating system uses for the hardware, and it is the one that software, support documents and the tables on this wiki tend to key on.
Apple uses these three terms itself, and this wiki follows them. Other references call the part number a "model", which is understandable but collides with the first term, so the distinction is worth holding onto. A iPhone 17 Pro bought in the United States is model A3287, identifier iPhone18,1, and one of a dozen part numbers depending on the color and capacity chosen.
The tables themselves are split by product family, one page each, because the full list runs to thousands of rows. This page explains how to read any of the codes and how to find them on a device; the family pages hold the data.
1 Model number✎
The model number is the one Apple prints on the product and registers with regulators. It has the form A plus four digits, and the same device usually has several. There is one for the United States, one for China, one for Japan and one for everywhere else, because the cellular radios differ by market. The iPhone 17 Pro is A3287 in the United States and Puerto Rico, A3525 across Canada, Japan and the Gulf states, A3527 in mainland China and A3526 elsewhere. Wi-Fi-only products, such as most iPads and every Mac, generally have a single model number worldwide.
Where it is printed has moved over the years. Early iPhones and most iPads carry it on the back, in the small text below the Apple logo. From the iPhone 8 onward the back is glass and the number moved into the SIM tray slot, on the side facing the display. On devices without a SIM tray it is etched inside the USB-C or Lightning connector, readable only under bright light. Macs carry it on the underside near the regulatory marks, and Apple Watch has it engraved on the back of the case.
The number is also available without a magnifying glass. On an iPhone or iPad, Settings → General → About shows a field labeled Model Number that actually contains the part number; tapping it toggles to the model number. On a Mac, About This Mac shows the model name, and the serial number entered at checkcoverage.apple.com returns the exact configuration.
2 Part number✎
The part number identifies a single stock-keeping unit: this model, in this finish, with this storage, for this region. It is the code on the box and in Apple's order system, and it is what a carrier, a reseller or a refurbisher means by "the SKU". A part number reads in three pieces.
| Piece | Example | Meaning |
|---|---|---|
| Prefix | MYX13LL/A | One character that says where the unit came from; see the table below. |
| Product code | MYX13LL/A | Four characters, letters and digits, that encode the model, the finish and the storage together. Two colors of the same phone have different codes, and so do two capacities. |
| Region and revision | MYX13LL/A | The market the unit was packaged for, then a revision letter. LL/A is the United States, J/A Japan, B/A the United Kingdom, X/A Australia, CH/A mainland China, KH/A South Korea, ZP/A Hong Kong. The letter after the slash advances when the bundle changes without the product changing. |
The prefix is the part most people never notice, and it is the most useful when buying second-hand. The meanings below are consistent across every product line.
| Prefix | Meaning |
|---|---|
| M | A new retail unit, the ordinary case. |
| F | A certified refurbished unit, as sold in Apple's own refurbished store. |
| G | Also refurbished, used on some newer products alongside F. |
| N | A replacement unit, supplied by Apple service in exchange for a faulty one. These are sold without retail packaging. |
| P | A personalized unit, ordered with engraving. |
| 3 | A demonstration unit, built for display in stores and not meant for sale. Demo units often carry product codes of their own. |
| 4, 5 | Units sold "as is" or without the standard Apple warranty. |
A part number therefore tells a buyer more than a listing usually does. An N unit is a service replacement that never came in a retail box, and a 3 unit spent its life on a store table.
3 Model identifier✎
The model identifier is the name the operating system gives the hardware, and it follows a fixed pattern. A family name is followed by a generation number, a comma and a variant number. The iPhone 17 Pro is iPhone18,1 and the iPhone 17 Pro Max is iPhone18,2. The 14-inch MacBook Pro with M4 Pro is Mac16,7. The generation number counts internal hardware platforms rather than marketing names, so it does not match the number on the box. The iPhone 17 family is generation 18 in this scheme, and the first iPhone was iPhone1,1.
This is the identifier that matters most for software. Firmware files, support databases and compatibility lists key on it, and it is what a device reports to Apple's servers. On a Mac, System Information shows it as "Model Identifier"; on an iPhone or iPad it is not displayed, but the tables on this wiki list it beside each model number.
Beneath the identifier sits a further internal name for the circuit board, such as V53AP for the iPhone 17 Pro. It appears in firmware and diagnostic output and almost nowhere else. The family pages record it for completeness, but it is not something an owner will ever need.
4 Finding a device in the tables✎
Start from whichever code is to hand. A part number from a box or a Settings screen is matched by its product code. Drop the prefix and everything from the region onward, so MYX13LL/A becomes YX13, and search the relevant family page for it. A model number from the device's case is listed directly, one or more per model. An identifier from a firmware file or a diagnostic report is listed beside each model as well.
Each family page is a single table sorted by release, one row per model, giving the model numbers, the identifier, the board name and the range of part numbers. The full grid of part numbers by finish and storage lives on the individual product page, where it sits beside the rest of that model's specifications.
