How to Find Your iPhone Model Number (and Why It Matters for Parts)

“iPhone 13” isn't one phone. Apple sells each model in several regional versions, each with its own model number — an “A” followed by four digits, such as A2633. For most owners that never matters. For anyone ordering a replacement part, it's the most reliable way to be sure what's on the bench.

This guide covers where to find the model number, what the other numbers in Settings mean, and a full table of model numbers from iPhone 8 to the current range.

Model name, part number and model number

Settings › General › About shows three things that are easy to mix up:

• Model Name — “iPhone 15 Pro”. Fine for a conversation, not precise enough for parts.
• Part number — something like MTUX3X/A. This is what Settings shows first next to Model Number. It encodes colour, storage and the market the phone was sold in.
• Model number — the A-number, e.g. A3102. Tap the part number once and it switches to this.

Two quick reads from the part number are handy when you're buying or repairing a second-hand phone:

• A part number ending in X/A means the phone was sold for the Australian market.
• The first letter hints at the phone's history: M is a normal retail unit, F is Apple-refurbished, N is a replacement unit issued by Apple, and P is a personalised (engraved) unit.

Where to find the model number

If the phone turns on: Settings › General › About, then tap the part number next to Model Number.

If it doesn't turn on:

• iPhone 8 and later with a SIM tray: pull the tray and look inside the slot, on the upper side (the display side). You'll need good light overhead.
• iPhones with no SIM tray: look inside the USB-C or Lightning port, on the upper side.
• iPhone 7 and earlier: it's printed on the back of the phone.

Why the region matters in a repair

Most repairs — screens, batteries, charge ports — use the same part across every regional version of a model. The model number still earns its place on the job ticket for two reasons.

US iPhones are physically different. From the iPhone 14 onwards, US models have no SIM tray and use eSIM only. So housings, frames and SIM-related parts for a US phone don't match an Australian one. Grey-import US iPhones are common here, and the model number is the fastest way to spot one before you order a back housing.

Same screen size doesn't mean the same screen. Apple's own figures put the iPhone XR, 11, 12, 12 Pro, 13, 13 Pro, 14 and 16e all at the same 6.06-inch diagonal. They aren't interchangeable: the XR and 11 use an LCD, the others OLED, and connectors and mounting differ between generations. Match parts by model, never by screen size.

Australian iPhone model numbers

Apple lists Australia under “other countries and regions”, so that's the number an Australian-market iPhone carries. The right-hand column lists the other regional versions, useful for identifying an import.

For older models Apple doesn't split the list by region, so check against all numbers:

A tip for repair shops

Write the model number on every job ticket and every parts order. It takes ten seconds with the SIM tray out, and it catches the two costly mistakes: ordering an Australian housing for a US import, and ordering by screen size.
