How can I identify if an iPhone is fake or not with the model number?

It's an iPhone that has been refurbished, but the remanufacturing work was not performed by Apple.

So, there might be a question about whether the phone came with a "new" or "used" battery for example.

If you bought the phone from a store that claimed that this was a "new" iPhone, it wasn't new.

Model numbers and serial numbers are routinely copied, which means model numbers and serial numbers and warranty status checks are not a useful or reliable means for detecting counterfeits.

That model number is probably associated with a 256 GB purple iPhone 14 Pro eSIM model, based on some Paraguayan websites. If it’s real. I don’t see that model listed elsewhere, and most of the Apple model numbers start with M, N, F, or P, and AFAIK not 5, and MQ1D3 (MQ1D3LL/A) is real.
