What makes you ask?

Contact the seller, seeing what they have to say on this.

Verify if this is a Genuine Device:

One important thing it seems to perform here, is to confirm that the iPhone is genuine. Here is how to do so:

1. Obtain the Serial Number: Find the Serial Number or IMEI on your iPhone, iPad, or iPod touch - Apple Support
2. Enter the Serial Number here: Check Your Service and Support Coverage - Apple Support
3. View the Results: If all shows up as an iPhone, then you have a genuine iPhone. If not, then it is fake, and you should return this to the seller.
