Accounts and user IDs

If you manage your accounts online at AT&T, you already have a user ID. If you have more than one account, you might have more than one user ID. Make sure to sign in with the ID for the account you want to manage.

You can access these accounts and apps with a single user ID:

  • AT&T WirelessSM, AT&T Mobile Services (like AT&T Messages), and AT&T NumberSync®
  • AT&T Internet, Internet Air, Fixed Wireless Internet, and DSL
  • Digital Phone and Landline - Home phone
  • U-verse® TV
  • AT&T Mail
  • AT&T app
  • AT&T Smart Home Manager app

FYI: If you have a DIRECTV® account, you can manage it on directv.com.
