Can I add my wife's phone on my Find My app?

Need help finding wife’s phone

Yes you can.

Start out by ”joining yourselves” into a “Family Sharing Group”

Set up Family Sharing - Apple Support

Then both of you configure your phones to allow location sharing in Settings -> Family. (right underneath your names)

This is a VERY useful feature; it not only allows you to easily Locate each other’s devices, but also “Play a Sound” and “Mark as Lost” all right from your own FindMy.

Here is some additional “just found” info on the matter which might also help:

Share your location with your family – Apple Support (AU)

Open any browser to www.icloud.com/find

Enter your wife's Apple ID and Apple ID Password

If her phone was set up with Find My, it might appear if the battery has not run down, the phone has not been powered off and the phone has an Internet connection where it is currently located

You don’t “add” any device.

Go to Settings -> Family -> Location Sharing.

You select “her” … and She selects “you”
