Hello @semiology,

We'd be more than happy to take a closer look into why you're unable to create an account.

We'll need some additional details in order for us to better assist you:

• Do you have a postpaid wireless account with AT&T, or an AT&T PREPAID account?
• When exactly do you get this error message while you're trying to set up your account?
• Does this occur when you enter your phone number and zip code?

Please let us know.

In the meantime, we recommend following the steps at this link to Create your User ID.

Hope this helps!

Sean, AT&T Community Specialist
