When you submit an order using the AT&T eOrder tool, you will receive an e-mail acknowledging that AT&T has received the order; you should retain this e-mail for future reference. This e-mail acknowledgement will contain an order number, which always begins with ISR followed by the date in YYMMDD format and five more numbers (e.g., ISR06040139586). This is the project number for your order.

In addition, the project number is displayed when you go through the checkout process. You may wish to jot down the project number for future reference, since you will need it when checking the status of your order.
