Use model number to identify your iPhone

It can be tough to know which iPhone model you own, especially since newer generations like the iPhone 13 and iPhone 15 look alike. Fortunately, each iPhone has a unique model number starting with A followed by four digits, such as A1865. In this blog, you’ll learn how to find your model number and see which model it refers to. We've provided a handy table to let you check it right away.

Why the model number matters

The model number provides exact details about your iPhone including model, production year and region. It’s useful when selling, choosing repairs or buying accessories. On newer iPhones, you can’t see the model externally, so this method is essential.

Where to find the model number

1. In Settings

Go to Settings > General > About. In the section “Model Number” you’ll first see an M or N number (sales number). Tap it to reveal the A‑number (model number).

2. On the back of the iPhone

For iPhone 7 and earlier models, the A‑number is printed under the Apple logo on the back.

3. In the SIM tray

Some models have the model number visible in the SIM tray, especially international variants.
