Why doesn't my iPhone 7 Plus have Face ID?

In that model, Face ID recognition wasn't available. It was introduced starting from iPhone X or later (except the new SE 2020, wich still has fingerprint recognition).

FaceID was introduced with the iPhone X. Your phone has TouchID, Apple's fingerprint technology.

Hello waris66,

Thank you for using Apple Support Communities! I understand from the information you've provided that you'd like to know if your iPhone 7 Plus has Face ID; I'd like to help.

The iPhone 7 Plus is not a model that is capable of supporting Face ID. The following support article specifies which iPhone and iPad models do support Face ID:

Best Regards.

The Face ID technology was introduced with the iPhone X in September 2017.

The iPhone 7 Plus is from September 2016. Your phone is too old to have Face ID.
