You need to de-register a number only if you want to use the same number on non-iOS devices. If that is not the case, simply forget it.
Remove your phone number
- On your iPhone, go to Settings > Messages > Send & Receive. Select your Apple ID and tap Sign Out. ...
- If the phone number that you want to remove belongs to an iPhone that you can't access, change your Apple ID password. This removes all phone numbers from your iPad, iPod touch, and Mac.
