01Checking the part number
- Open Settings. Go to General › About.
- Tap Model Number. One tap turns the value into the part number (e.g. a code starting with M).
- Look at the first letter. It is generally read as follows:
| First letter | Meaning |
|---|---|
| M | New (retail) device |
| F | Refurbished device |
| N | Replacement device |
| P | Personalised (engraved) device |
02Parts and Service History
On recent iOS versions, Settings › General › About includes a Parts and Service History section. If a part such as the screen, battery or camera has been replaced, it appears here and may be marked “Genuine Apple Part” or “Unknown Part”. If the section does not appear, there is no replacement record to list.
03Box, screws and appearance
- Box. Replacement devices usually come in plain white boxes without a picture of the model.
- Screws. Scratches or wear on the screws next to the charging port can mean the phone has been opened.
- Screen edge. A gap or adhesive marks between the screen and frame can mean the screen was removed.
