There are several ways to locate your APS account number:
On Your Bill - The upper right corner on page one of your statement will list your account number.
Online - Log in and navigate to the 'my account' page. If you have given your account a nickname, your account number is not going to show in the blue 'my account' section. Instead, pull up a copy of your bill by clicking on 'view bill'.
App - Select the 'my bill' tab and view the 'account number' field. If you have given your account a nickname, your account number is not going to show.
By Phone - Call us at 602-371-7171 (metro Phoenix) or (800) 253-9405 (other areas) from the phone number associated with your APS account and confirm the house number you are calling about. The automated phone system will then provide your account number, balance, and due date.
