About model A3289

The model number A3289 belongs to the iPhone 16 Plus (device identifier iPhone17,4). Apple assigns multiple model numbers to each device for regional and connectivity variants, so one device usually carries several of them.

How do I find the model number on my device?

Open Settings > General > About and read the Model Number field. The number is also printed in the fine print on the back of the device and, on some models, on the SIM tray. Our model identification guide walks through every method.

What is the difference between A3082, A3290, A3291 and A3289?

Nothing software-related. These model numbers all refer to the same iPhone 16 Plus; Apple uses them for regional and connectivity variants, and firmware support is identical across all of them.
