No matter when it was originally purchased, it's an old phone that cannot update past iOS 15.
If you are asking about checking coverage using serial numbers because you are thinking of purchasing a used iPhone 7 Plus, you might want to set your sights on something newer that can run iOS 18. And you also should read The All Too Common SAD Reality of Buying a Used iPad/iPhone – Apple Community .
Coverage expired for the iPhone 7 Plus long ago. After the initial extended optional period, it was not possible to add continued coverage.
Apple discontinued that phone in September 2019 in the U.S. market. Even if they sold it a bit longer elsewhere, it must have been years since they discontinued it – and the standard warranty is only 1 year.
I'm guessing that the coverage expired on your iPhone 7 Plus years ago.
I just wanna check when it was purchased
