Every iPhone comes with a unique model number that reveals key details about the device, such as whether it’s new or refurbished, the region it was sold in, and even its specific variant. Understanding the iPhone model numbers and what the letters and numbers mean will help you to make better informed decision on your next iPhone purchase. So, if you’ve ever wondered what your iPhone’s model number means, this guide will break it down for you.
Where to Find Your iPhone Model Number
You can find your iPhone’s model number in two ways:
- In Settings:
- Go to Settings > General > About.
- Tap on Model Number to switch between the part number and model number.
- On the Device:
- If you have an older iPhone (iPhone 7 and earlier), the model number is printed on the back.
- For newer models, check the SIM tray for the model number.
Now, let’s break down what the letters and numbers in the model number mean.
Understanding iPhone Model Numbers
An iPhone model number follows a format like MTU63LL/A. Each letter and number in this sequence has a specific meaning.
1. The First Letter: Device Condition
The first letter of the model number tells you whether the iPhone is new, refurbished, or a replacement.
| First Letter | Meaning |
|---|---|
| M | Brand-new retail unit |
| F | Refurbished unit from Apple |
| N | Replacement unit (usually provided under warranty) |
| P | Personalized unit (engraved by Apple) |
For example, in MTU63LL/A, the M means the iPhone was sold as a brand-new device.
2. The Middle Characters: Model and Variant
The next set of letters and numbers (e.g., TU63) represents the specific model, configuration, and storage size of the iPhone. Apple assigns these codes internally, and they can change based on color, carrier, and storage capacity.
3. The Region Code (Before the Slash)
The next two letters before the slash indicate the region where the iPhone was intended to be sold.
| Code | Region |
|---|---|
| LL | United States |
| J | Japan |
| CH | China |
| B | United Kingdom, Ireland |
| X | Australia, New Zealand |
| KH | South Korea |
| ZP | Hong Kong, Macau |
| TA | Taiwan |
| RS | Russia |
| TU | Turkey |
| CZ | Czech Republic |
For example, MTU63LL/A has LL, meaning it was intended for sale in the United States.
4. The Final Letter After the Slash
The last letter after the slash (/A) doesn’t have a major impact on the device itself but can sometimes indicate minor hardware or software revisions.
Why Do Model Numbers Matter?
Understanding your iPhone’s model number is useful for several reasons:
- Checking if Your iPhone is New or Refurbished – If you bought a second-hand iPhone, the first letter can help you verify if it was new, refurbished, or a replacement.
- Ensuring Regional Compatibility – Some iPhones have region-specific features, such as Japan requiring a shutter sound or certain models supporting dual SIM in China.
- Warranty and Repairs – Apple may require your model number when checking warranty coverage or repairing your device.
Note: The model number on your iPhone isn’t just a random string of characters—it provides valuable insights into your device’s origin and status. Now that you know how to decode it, you can easily check if your iPhone is brand new, refurbished, or a regional variant.
Next time you’re buying an iPhone, especially a second-hand one, be sure to check the model number to ensure you’re getting exactly what you expect!
