Step 1: Check Your iPhone Model Number

The easiest way to identify your iPhone model is by locating the model number.

  1. Go to Settings
    • Open the Settings app on your iPhone.
    • Navigate to General > About.
    • Look for Model Name and Model Number
  2. Decode the Model Number
    The model number typically starts with "A" (e.g., A2342) and can be cross-referenced with the official list of Apple iPhone models in Step 5.

Step 2: Check the Back of Your iPhone

Older iPhones (up to iPhone 8 and 8 Plus) have the model number printed on the back cover near the bottom. If your iPhone doesn’t display it there, proceed to the next steps.

Step 3: Compare Physical Features

Each iPhone model has unique physical characteristics:

  • Camera Layout: Number of lenses and their placement. One rear camera on older models (iPhone 7 or 8), newer minimalist models (iPhone 16e, iPhone Air). Two rear cameras on standard (non-Pro) iPhones that are diagonal (iPhone 13, iPhone 14, iPhone 15) or vertical (iPhone 16, 17, iPhone 18). Three rear cameras on Pro models. The newest iPhone 18 Pro/Pro Max or iPhone 17 Pro/Pro Max models have a rectangular, extended camera plateau that protrudes across the entire back.
  • Screen Size: Measured diagonally.
  • Notch or Home Button: Modern iPhones have Face ID with a notch, while older models use Touch ID (integrated into a large, circular Home button on the front chin of the phone, surrounded by a distinct steel ring used to detect the touch of your finger) and a Home button. On the iPhone Duo, the TouchID is integrated directly into the elongated Side/Power button on the right edge of the device as a narrow, capacitive strip built into the lock button rather than a front-facing button
  • Ring/Silent Toggle Switch: Every standard, Pro, Plus, and mini model in these generations (e.g. iPhone 14 Pro, iPhone 13, iPhone 11, iPhone X, iPhone 8, etc.) has the physical sliding switch above the volume buttons to mute or unmute.
  • Action Button: iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16 lineup (all models: 16, 16 Plus, 16 Pro, 16 Pro Max) and  the iPhone 17 series and iPhone 18 Pro and iPhone 18 Pro Max
    have a customizable physical button, positioned directly above the volume buttons where the ring/silent switch used to be. The button allows you to press and hold to instantly launch a specific feature, app, or automation or toggle between ring and silent.
  • Camera Control Button: This is a flush, force-sensitive mechanical button located on the lower right side of the phone, designed to make capturing photos and videos faster and more intuitive. This is available on the iPhone 16 lineup, iPhone 17 series, iPhone 18 Pro, iPhone 18 Pro Max and Apple iPhone Duo. Unlike standard physical buttons, the Camera Control blends a mechanical click with a capacitive touch sensor and a high-precision force sensor to support multiple gestures.
  • USB-C port: Newer models from the iPhone 15 series or later use USB-C, while older models from the iPhone 14 series or earlier use a Lightning port.

Use these features to visually compare your iPhone to Apple’s official images.

Step 4: Use Your iPhone’s IMEI Number

You can find the IMEI number:

  • In Settings under General > About.
  • Printed inside the Charging Port (USB-C or Lightning). The physical hardware model number is laser-printed on U.S. models of the iPhone 14 series, iPhone 15 series, iPhone 16 series, iPhone Duo, and newer devices that rely entirely on eSIM and lack a SIM tray. Look directly inside the bottom charging port connector. It is laser-printed in incredibly tiny text along the upper inner lip. You will need bright lighting and a magnifying glass or your phone's camera zoom to read it cleanly.
  • Printed on the SIM tray. On iPhone 8 through iPhone 13 series in all regions, and global/international versions of the iPhone 14 and newer models that still feature a physical SIM tray. Remove your SIM card tray using a pin tool. Look inside the empty SIM slot cavity. The model number is printed along the upper side of the slot (the side closest to the display panel)
  • Laser-Printed on the External Back Glass. On iPhone 7, iPhone 7 Plus and and all older generations. Flip the phone over. The model number is printed right on the lower back housing under the "iPhone" branding, starting with an "A" followed by four digits (e.g., A1660).

You can use the IMEI to get detailed information about your iPhone by visiting Apple's IMEI lookup.

Step 5: Reference Apple’s Model Number List

Here’s a quick look at popular iPhone models and their model numbers:

  • iPhone 4S: A1431, A1387
  • iPhone 4: A1349, A1332

Why Knowing Your iPhone Model Matters

Understanding your iPhone model can help you:

  • Ensure compatibility with apps, accessories, and updates.
  • Get the correct troubleshooting support.
  • Buy the right replacement parts or protective cases.
