How to pay your SRP bill online, by phone, or in person
Salt River Project offers four main ways to pay your bill: online through their website or mobile app, by phone, by mail, or in person at a payment location. The fastest and most convenient method is online — you can pay immediately without waiting for mail delivery or phone queues. If you prefer not to use the internet, you can call SRP's automated payment line or visit a local payment center.
Each method has different timing. Online and phone payments post to your account the same day if made before 5 p.m. Arizona time on a business day. Mail payments take 7 to 10 business days to reach SRP and post to your account, so you need to send them well before your due date. In-person payments at SRP offices or authorized retailers post immediately.
You do not need to create an online account to pay once — you can make a one-time payment without logging in. However, setting up an account takes about five minutes and lets you see your bill details, set up automatic payments, and track your payment history.

Paying online through the SRP website or app
Go to srpnet.com and select "Pay My Bill" at the top of the page. You can pay as a guest without logging in — enter your account number (found on your bill), the amount you want to pay, and your payment method. SRP accepts debit cards, credit cards, and bank account transfers. Credit card payments may include a processing fee, which SRP will show you before you confirm.
If you create a free online account, you can save your payment methods, view your bill online, and set up automatic monthly payments. To create an account, select "Create Account" on the login page and provide your account number, service address, and email. SRP will send you a confirmation link — click it to activate your account.
The SRP mobile app (available on iOS and Android) offers the same payment options as the website. Download the app, tap "Pay My Bill," and follow the same steps. Payments made through the app post at the same speed as website payments.
Paying by phone or automatic payment
Call SRP's automated payment line at 1-602-371-6000 to pay by phone. You will need your account number and a debit card or bank account number. The system accepts payments 24 hours a day, 7 days a week. Payments made before 5 p.m. Arizona time on a business day post the same day.
To set up automatic monthly payments, log into your online account and select "Autopay" or "Automatic Payment." Choose the date you want the payment to come out each month (usually your due date) and your payment method. You can change or cancel automatic payments anytime through your account. If you prefer to set up autopay by phone, call SRP's customer service at 1-602-371-6000 during business hours and ask to speak with a representative.
Automatic payments remove the risk of forgetting a due date. If your bill amount varies month to month (which is common with SRP, since rates change with season), you can set up autopay to pay a fixed amount or to pay your full bill automatically each month.
Paying by mail or at a payment location
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. SRP's mailing address is typically listed on the back of your bill or in the "Pay Your Bill" section of their website. Mail payments take 7 to 10 business days to arrive and post, so send your payment at least 10 business days before your due date.
You can also pay in person at SRP payment centers located throughout the Phoenix area. Visit srpnet.com and select "Payment Locations" to find the office nearest you and its hours. In-person payments post immediately, and you receive a receipt on the spot. Some SRP payment centers accept cash, check, debit card, and credit card, though payment methods vary by location — call ahead if you want to confirm what forms of payment a specific office accepts.
Authorized retailers in Arizona also accept SRP payments. These include some grocery stores, pharmacies, and check-cashing services. Ask at the customer service desk whether they accept utility bill payments, and provide your account number and payment amount.
Understanding due dates and late fees
Your due date appears on your bill, typically 18 to 20 days after the bill is issued. SRP considers a payment late if it is not received by 5 p.m. Arizona time on the due date. This means a check mailed on the due date will almost certainly be late, since it takes 7 to 10 days to arrive. If you choose to pay by mail, plan to send your payment at least 10 business days early.
If your payment is not received by the due date, SRP adds a late fee to your next bill. The amount of the late fee depends on your bill amount and SRP's current rate — check your bill or contact SRP for the exact fee. Late payments can also affect your account status and may result in a service disconnection notice if payments continue to be missed.
If you are having trouble paying your bill on time, contact SRP's customer service to discuss payment arrangements or programs that may help. SRP offers budget billing (which spreads your annual costs evenly across 12 months) and other options for customers facing hardship.
What to do if your payment does not post
If you paid online or by phone and your account still shows the payment as unpaid after one business day, log into your account and check the payment status. Most online payments show a confirmation number immediately after you submit them — save this number in case you need to contact SRP.
If a payment you made by mail or in person does not appear on your bill within 10 business days, call SRP customer service at 1-602-371-6000 with your confirmation number or receipt. Have your account number ready. SRP can look up the payment and confirm when it posted. If there is a discrepancy, SRP can adjust your account or reissue a payment if it was lost.
Keep receipts or confirmation numbers for all payments for at least one billing cycle. If a dispute arises about whether a payment was received, these records protect you and make it easier for SRP to resolve the issue quickly.
Frequently Asked Questions
Can I pay my SRP bill with a credit card without a fee?
SRP does not charge a fee for debit card or bank account payments, but credit card payments include a processing fee. The fee amount varies and SRP shows it to you before you confirm the payment. If you want to avoid the fee, use a debit card or bank account transfer instead.
What happens if I pay after my due date?
SRP adds a late fee to your next bill if payment is not received by 5 p.m. Arizona time on your due date. Repeated late payments can result in a service disconnection notice. If you are unable to pay on time, contact SRP to discuss payment plans or hardship programs.
Can I set up automatic payments for a different amount each month?
No, automatic payments are set to a fixed amount. However, you can choose to pay your full bill automatically each month, and SRP will charge whatever the full amount is. Alternatively, you can set a fixed amount and manually pay any remaining balance after the automatic payment posts.
Is it safe to pay SRP online?
SRP's website and app use encryption to protect your payment information. You should never share your account number or payment details with anyone claiming to represent SRP unless you initiated the contact. If you are unsure whether a payment request is legitimate, call SRP directly at 1-602-371-6000.
How do I change my automatic payment date?
Log into your online account, go to the Autopay section, and select "Edit" or "Change Payment Date." Choose a new date and confirm. The change takes effect on your next billing cycle. If you need help, call SRP customer service at 1-602-371-6000.
