A subaccount is a member ID email address set up under the account owner’s member ID. Only the account owner can create and manage subaccounts. For example, the account owner would have a primary member ID, and their spouse or children would have subaccount member ID.

• You can have up to 20 subaccounts under your primary member ID. Only 10 can be active at one time.
• You can't delete subaccounts, but you can disable them.
• Subaccount users can manage phone features, get product support, and chat with an agent.
• The member ID email for a subaccount won’t appear on the bill.
• You’re required to complete a few extra steps if you create a subaccount for a child under the age of 13.

Heads up: Free AT&T email accounts that aren't associated with a home internet service from AT&T can't create subaccounts.
