AutoPay Frequently Asked Questions

What is a routing number?

A routing number is a unique identifying number assigned to a bank or other financial institution by the American Bankers Association used to route check and transactions (see check example below). It is usually the first nine digits found at the lower left-hand corner of your personal check. If you can't find the routing number for your account, or need assistance, your bank can help you.

What if I don't know my water account number?

If you don't know your water account number, please speak to a representative from our PHX Customer Services Division at (602) 262-6251.

Will I still receive a City Services bill from the city of Phoenix?

 Yes, you will continue to receive a bill showing the total amount due. There will be a message on the bottom portion of the bill if an automatic payment will be made.

When will the funds be withdrawn from my checking or savings account?

In most cases the funds will be withdrawn on or after the due date on the bill; however, in some rare cases it is possible that the funds could be withdrawn up to one week before the due date on the bill. A specific date cannot be determined.

Can I request the funds to be withdrawn on a certain date?

No. If you must have funds withdrawn on a certain date, you will not be able to participate in the AutoPay program.

Can I still donate each month to Project Assist when I am enrolled in the AutoPay program?

Your AutoPay enrollment form allows you to specify a monthly donation amount.  You may also pay a one-time donation by sending it to:

City of Phoenix Human Services Department
