For cell/wireless service, it's your wireless phone number.

For Uverse, it's your att.net email address.

At least that's how mine is.

My email address is *** in reference to the above account.

I do not have multiple accounts so I do not see the need to have an access ID to register on the main att.com site.  I am simply trying to pay an online bill for $46.33 which I forgot to pay by mail.

I own a EL51200/EL51210/E51250 DET 6.0 cordless telephone with caller ID. I would like to eliminate two numbers which I have entered. Can I do that, please?

I do not need an account. I only need the solution to my question.
