Spot fake, refurbished or replaced iPhones. Check the model number, serial, parts history and Find My status before you buy.

The model number's first letter tells you the iPhone's origin.
Short answer

In Settings › General › About, look at the Model Number: M means brand new, F means refurbished, N means a replacement and P means personalised. Then check serial number, parts history and Find My status.

The model number is a quick tell for a phone's history. Combine it with other checks for a confident decision.
