Model Name, not Model Number. The line underneath shows something like MTQE3X/A – that's a manufacturing code and won't help you choose a case.
Same year doesn't mean same size. An iPhone 17, 17 Pro, Air and 17 Pro Max are four different bodies with different camera layouts. A case made for one won't fit the others, even though the names look almost identical.
Buying for someone else? If you can't get to their phone, the model is printed on the original box, or on the receipt from their carrier or the Apple Store.
And if you do get it wrong, we'll sort it out.
