Learn how you can manage multiple accounts with a single AT&T ID.
You can link these account types to an AT&T ID:
Linking accounts won’t combine your bills or bundle your services. It just gives you easy access to view your accounts with a single ID and password.
You can’t unlink combined accounts (multiple services on the same account number), U-verse TV, AT&T Internet, or AT&T Internet Air if you have primary online access. You also can’t unlink FirstNet or suspended accounts.
