Amazon has the ability to record the serial number. I have not SEd iPhone however I did an Apple Watch S5 and in my case whoever put the SN information got it wrong. The SN that was listed in my order details was different to what was on the product/box.

Same experience. The S/N of my AirPods were different form the S/N of the invoice on the amazon page.

What's the precise weight of the phone?

The weight of the package should be around 250g.
