Where can I find my account number to use for billpay?
Your account name is your username - but I'd advise against using bank-based billpay, as the for most services the billing amount varies due to changes in tax rates. And, most bank bill pay systems simply print and mail checks, we we don't accept for most of our services. There can also be substantial delay between issuance and mailing of the check and processing, which can result in late fees or suspension of services.
Instead, check out the payment options in the member tools: we now support both bank debit or payment via a credit or debit card. You can make any changes you need to at any time online.
