SunPass is Florida's electronic toll collection system, and you pay it through your prepaid account rather than at a booth

SunPass is the prepaid toll payment system used on Florida's toll roads, bridges, and expressways. Instead of stopping at a toll booth, you mount a small transponder in your vehicle, and tolls are deducted automatically from your account balance as you drive. You maintain that balance by adding money to your account before or as your balance runs low.

The system is operated by the Florida Department of Transportation. You can add funds online through the SunPass website, by phone, by mail, or at authorized retail locations. Most accounts are set up to allow automatic replenishment — the system adds money when your balance drops below a threshold you choose — but you can also make one-time payments whenever you want.

Key Takeaways

  • SunPass accounts require a prepaid balance that decreases each time you use a toll road; you add money back through several payment methods.
  • Online payment through the official SunPass website is the fastest option and lets you set up automatic replenishment or pay once.
  • Phone payment, mail payment, and retail location payment are available if you do not have internet access or prefer not to pay online.
  • Automatic replenishment can prevent your account from running empty, but you control the trigger amount and can turn it off at any time.
  • If you dispute a toll charge or believe your account was charged in error, SunPass has a formal dispute process separate from payment.

Paying online through the SunPass website

The SunPass website (sunpass.com) is the primary payment method. Log in with your account number and PIN, or create an account if you do not have one yet. Once logged in, you can see your current balance, recent toll history, and payment options.

To make a one-time payment, select "Add Funds" or "Make a Payment," enter the dollar amount you want to add, and choose your payment method — credit card, debit card, or bank account. The payment typically posts within one business day. You can also set up automatic replenishment, which charges your card or bank account whenever your balance falls below a level you set (for example, $10 or $25).

If you have multiple vehicles on one account, you can manage each transponder separately and see which vehicle used which toll. This is useful if you want to track spending or dispute a specific charge.

Paying by phone or mail

You can call the SunPass customer service line at 1-888-SUNPASS (1-888-786-7277) to make a payment by phone. Have your account number and a credit card, debit card, or bank account information ready. A representative will process your payment, and it typically posts within one business day.

To pay by mail, send a check or money order to the address listed on your SunPass bill or on the website. Include your account number on the check. Mail payments take longer — typically five to seven business days to post — so use this method only if you have time before your balance runs out.

Paying at retail locations

You can add funds to your SunPass account at authorized retail locations throughout Florida, including many grocery stores, gas stations, and convenience stores. Look for the SunPass logo in the window. The retailer will take your payment (cash or card) and provide a receipt with a confirmation number.

Retail payments typically post within 24 hours. This option is useful if you do not have internet access or prefer to pay in person, but it requires you to know which stores near you accept SunPass payments.

Setting up and managing automatic replenishment

Automatic replenishment is optional but can prevent your account from running empty unexpectedly. When you set it up, you choose a trigger amount — the balance at which the system will automatically charge your card or bank account — and a replenishment amount — how much money to add each time.

For example, you might set it to add $50 whenever your balance drops below $10. You can change these settings at any time through your online account, or by calling customer service. You can also pause or turn off automatic replenishment if you want to manage payments manually.

If a replenishment charge fails (for example, if your card has expired), SunPass will attempt to charge you again, but your account will not be suspended when ready. You will receive a notice and can update your payment method or make a manual payment to keep your account active.

What happens if your balance runs out

If your SunPass balance reaches zero, you cannot use toll roads without adding funds first. Some toll roads have alternative payment methods — you may be able to pay by mail or through a violation notice — but this is slower and may include a processing fee.

If you drive through a toll without a valid prepaid balance and without paying through an alternative method, you will receive a toll violation notice in the mail. This notice includes the toll amount plus a violation fee, and you must pay it within a set time frame to avoid additional penalties.

To avoid this, monitor your balance regularly through the SunPass website or set up automatic replenishment so your account stays active.

Disputing charges and account errors

If you believe you were charged incorrectly — for example, if you were charged twice for one toll or charged for a toll you did not use — you can file a dispute through your SunPass account or by calling customer service. SunPass will review your toll history and the transponder data to investigate.

Disputes are separate from payment. Filing a dispute does not stop your account from being charged for future tolls, and it does not reverse a charge when ready. SunPass typically investigates disputes within 30 to 60 days and will refund your account if the charge was found to be in error.

Frequently Asked Questions

Can I pay my SunPass bill with cash?

Yes, but only at authorized retail locations. Online, phone, and mail payments require a credit card, debit card, or bank account. Check the SunPass website to find retail locations near you that accept cash payments.

How long does it take for a payment to show up in my account?

Online and phone payments typically post within one business day. Retail payments usually post within 24 hours. Mail payments take five to seven business days. Plan ahead if your balance is low.

What if I set up automatic replenishment and then do not use the toll roads?

Your account will not be charged if your balance does not fall below the trigger amount you set. You can turn off automatic replenishment at any time through your online account or by calling customer service, and any unused balance remains in your account.

Can I transfer money from one SunPass account to another?

No, you cannot transfer funds between accounts. Each account is separate. If you have multiple vehicles, you can add them to one account and manage them together, which is simpler than maintaining separate accounts.

What should I do if my payment was declined?

Log into your SunPass account and check the payment status. If the payment failed, update your payment method (card expiration date, address, or bank account information) and try again. You can also call customer service to troubleshoot the issue.
