Why is my wife's phone number associated with my name on iPhone?

Lobsterghost1: Yes, we both share the same Apple I.D. Are you suggesting that could be the issue? If so, how can I delete my wife from our shared Apple I.D. & then assign a separate I.D. for her? Thank you for your input.

See these instructions:

How to “unshare” an Apple ID - Apple Community

Do both phones share the same Apple ID?

That is absolutely the issue. You should NOT share an Apple ID. Each person needs their own.

It could be because you’re using the same Apple ID.

I recently restored both my iPhone 13 & my wife's iPhone 13 Max from iCloud back-ups. For some reason, when my wife composes a text message to me, her phone number is associated with my name. I checked our entries in Contacts, where each of us have our own entry, and the phone numbers for each of us are correct.

Could someone please help me sort this out? Thank you so much.

Restored why, what was the original issue?

Having separate Apple IDs seems to be the solution. Once I delete my wife from our shared ID & then create an ID of her own, will my individual Apple Music subscription sync with her iPhone once Family Sharing is turned on? Or must I get a family Apple Music subscription? Thank you.

You'll need a Family subscription in order to share.
