Log in to your City of Phoenix water account through the online portal
The City of Phoenix water billing system uses a portal called AZCities Online Services. To log in, go to the City of Phoenix website, find the Utilities section, and look for the "Pay My Bill" or "Online Services" link. You will need your account number (found on your water bill) and either a PIN you created during registration or your Social Security number to verify your identity.
If you do not have an online account yet, you can create one directly on the portal. The registration process takes a few minutes and requires your account number, service address, and a valid email address. Once registered, you can log in anytime to view your balance, payment history, and usage details.
The portal works on desktop computers, tablets, and mobile phones. You can access it 24 hours a day, 7 days a week. If you forget your password, use the "Forgot Password" link on the login page to reset it through your email.

What information you need before you log in
Have your water bill in front of you when you attempt to log in for the first time. You will need your account number, which appears near the top of your bill. You will also need your service address — the address where the water meter is located, which may differ from your mailing address if you have a P.O. box.
If you are registering a new account, you will create a PIN or password during setup. Write this down in a safe place. If you are logging into an existing account, use the PIN you created when you first registered, or use your Social Security number if you do not remember the PIN.
How to pay your bill once you are logged in
After logging in, look for a button or menu option labeled "Pay Now," "Make a Payment," or "Pay My Bill." The portal will show your current balance and the due date. You can pay the full amount or a partial payment if you prefer.
Select your payment method: bank account (ACH transfer), debit card, or credit card. Bank account payments typically have no fee and process within one to two business days. Debit and credit card payments may include a processing fee, which the portal will show you before you confirm the payment.
Enter your payment information and review the amount one more time before submitting. You will receive a confirmation number immediately, and the City of Phoenix will send a receipt to your email address. Keep the confirmation number for your records.
Setting up automatic payments to avoid late bills
The online portal lets you set up automatic recurring payments so you do not have to log in each billing cycle. This is useful if your bill amount stays roughly the same month to month. To set this up, log in and look for "Autopay," "Automatic Payments," or "Recurring Payments" in the menu.
You will choose a payment date (usually a few days before your bill is due), select your payment method, and confirm the amount. The system will deduct that amount from your bank account or card on the date you choose, every billing period. You can change or cancel the automatic payment anytime by logging back in.
If your bill varies significantly from month to month, you may prefer to pay manually each time so you can adjust the amount. The portal makes both options equally simple.
What to do if you cannot log in or forget your password
If you see an error message when you try to log in, first check that you are using the correct account number and that you have entered your PIN or Social Security number exactly as it appears on file. Account numbers are case-sensitive in some systems, so verify capitalization and spacing.
If you forget your password or PIN, click "Forgot Password" on the login page. The system will send a reset link to the email address on file. Follow the link to create a new password, then try logging in again. This usually takes a few minutes.
If you still cannot log in after resetting your password, or if you do not remember the email address you used to register, contact the City of Phoenix Water Services customer service line. They can verify your identity and either reset your account or help you pay over the phone.
Paying by phone or mail if you prefer not to use the online portal
You do not have to use the online portal to pay your bill. The City of Phoenix accepts payments by phone, mail, and in person at payment centers. To pay by phone, call the Water Services customer service line with your account number and payment method ready. A representative will process your payment and give you a confirmation number.
To pay by mail, write a check or money order, include your account number on the payment, and mail it to the address shown on your bill. Mail payments take longer to process — typically 7 to 10 business days — so send them early if your due date is approaching.
Some City of Phoenix locations also accept in-person payments at designated payment centers during business hours. Check the City of Phoenix website for the nearest location and hours.
Understanding your bill and usage after you log in
Once you are logged into the portal, you can view more than just your balance. The system shows your usage history — how many gallons of water you used in the current billing period and in previous months. This helps you spot unusual spikes that might indicate a leak.
The bill also breaks down charges: the base service charge (a fixed monthly fee), the volume charge (based on how much water you used), and any taxes or fees. If you have questions about a specific charge, the portal often includes a detailed breakdown you can review before paying.
You can also view your payment history in the portal, showing every payment you have made and when it was processed. This is useful for your records and for confirming that a payment went through.
Frequently Asked Questions
