Set up your ID for NumberSync

Heads up: Each wireless number on your account that uses NumberSync should have its own ID. This ensures that all calls sent to and from a synced device are linked to the right number.

• You already have a user ID if you manage your wireless account online. For NumberSync, use the ID listed on your online profile. NumberSync isn’t available for AT&T PREPAID^SM.
• Have an ID that isn’t linked to your wireless number yet? Learn how to assign your wireless number to your ID.
• Not sure what your ID is? Go to the Forgot ID page and follow the prompts.
