iPhone 13 Pro Max - Express Replacement Service

Whether it is brand new or re-manufactured you will honestly not know the difference apart from the model number. They aren't cleaned-up used phones.

There can't be many remanufactured 13's just yet anyway.

I did the same thing last month (within the 14 day period) and my phone came in a white box and the model number starts with “N” which I just learned means replacement. I spoke with an Apple Care support supervisor when I received it a couple of weeks ago, to ask if I was getting a new or used phone, and she told me that Apple doesn’t send out used phones. So, I’m not really sure if mine is new or not. It’s also a 13 ProMax.

Since they just came out, I’m hoping it was actually new, but from what I’ve been reading, there’s no way to know for sure.

The replacement could still be brand new. It is so that Apple have some warranty history if the init is subsequently brought it.

If a unit is remanufactured it is mostly new parts anyway. They are neither "used" nor "refurbished" in the normal usage of the words.
