I have a iPad and iPhone with the same Apple ID, but on Game Center I have used the same id for both devices and they are two different profiles and I was wondering how to have one of the accounts on both devices.

Hi Jamesdwills,

Welcome to the Support Communities!

If you are using the same Apple ID on both devices, the Game Center profile should be the same.

Check out this information from the iPad User Guide. Try signing out of the Game Center on both devices and then sign back in with the correct Apple ID:

Game Center settings - iPad User Guide

Game Center settings

Go to Settings > Game Center, where you can:

Sign out (tap your Apple ID)

Allow invites

Let nearby players find you

Edit your Game Center profile (tap your nickname)

Get friend recommendations from Contacts or Facebook

Specify which notifications you want for Game Center. Go to Settings > Notifications > Game Center. If Game Center doesn’t appear, turn on Notifications.

Change restrictions for Game Center. Go to Settings > General > Restrictions.

Cheers,

- Judy
