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

When you drive on Florida's toll roads—including the Florida Turnpike, Sunshine Skyway Bridge, and most highways in the state—you need either a SunPass transponder or a valid payment method on file. SunPass reads your transponder as you pass through a toll plaza and deducts the toll amount from your account balance. If you don't have a transponder, the system photographs your license plate and bills you by mail, though this method costs more per toll.

You can set up a SunPass account online, by phone, or in person. The account itself is free to open. You load money into it in advance, and tolls are deducted automatically as you use the roads. The system works across Florida and is also accepted on toll roads in Georgia, North Carolina, and other states that participate in the interoperability network.

Key Takeaways

  • You can pay tolls through SunPass by setting up a prepaid account online at sunpass.com, by calling 1-888-865-5352, or at a Customer Service Center.
  • A SunPass transponder costs between $10 and $25 depending on the type, and this cost is credited toward your first toll payments.
  • You can add money to your account using a credit card, debit card, or bank account, and the system will alert you when your balance runs low.
  • If you don't have a transponder, the system will bill you by mail at a higher per-toll rate, so getting a transponder saves money over time.
  • Your account balance and toll history are visible online anytime, and you can set up automatic replenishment so you never run out of funds.

Setting up a new SunPass account online

Go to sunpass.com and click "Open an Account." You'll enter your vehicle information (license plate, vehicle type, and VIN), your name and address, and your payment method. The site will ask whether you want a transponder mailed to you or whether you plan to use Pay-by-Plate (the license plate billing option). If you choose a transponder, you'll select the type: a standard transponder, a mini transponder that fits on a motorcycle, or a sticker transponder for rental cars or vehicles you don't own.

After you complete the form, you'll be asked to load an initial balance onto the account. Most people add $25 to $100, depending on how often they expect to use toll roads. The transponder will arrive by mail within 7 to 10 business days. Once it arrives, you'll mount it on your windshield or dashboard according to the instructions included in the package. The system will recognize it the next time you pass through a toll plaza.

Adding money to your account

Log into your SunPass account at sunpass.com using your username and password. Click "Add Funds" or "Replenish Account." You can pay with a Visa, Mastercard, American Express, or Discover card, or you can link a bank account for direct debit. Enter the amount you want to add—there is no minimum, though most people add at least $25 at a time.

The money is available in your account when ready. You can also set up automatic replenishment, which adds a set amount to your account whenever the balance drops below a threshold you choose. For example, you could set it to automatically add $50 whenever your balance falls below $10. This prevents your account from running empty while you're on the road.

Paying tolls without a transponder

If you don't have a SunPass transponder, the toll plaza cameras will photograph your license plate as you pass through. The system will match your plate to your vehicle registration and send you a bill by mail. This method is called Pay-by-Plate, and it works, but it costs more: tolls are typically 25 to 50 percent higher when paid by plate than when paid with a transponder.

You can still set up a SunPass account and choose Pay-by-Plate as your payment method. Go to sunpass.com, open an account, and select "Pay-by-Plate" instead of ordering a transponder. You'll load money onto the account the same way, and tolls will be deducted from that balance instead of being billed separately. This is cheaper than receiving individual bills by mail, though it's still more expensive than using a transponder.

Checking your balance and toll history

Log into your account at sunpass.com anytime to see your current balance, recent toll charges, and account details. The site shows the date, time, location, and amount of each toll you've paid. You can also read statements for your records or for reimbursement if your employer covers tolls.

If your balance is low, you'll receive an email or text alert (depending on your notification settings). You can change your alert threshold in your account settings so you're notified before your balance gets too low. This gives you time to add funds before you run out.

Updating your payment method or account information

If your credit card expires, is lost, or you want to switch to a different card, log into sunpass.com and go to "Account Settings" or "Payment Method." You can update your card information, change your billing address, or add a backup payment method. Changes take effect when ready.

If you move to a new address, update it in your account settings so your statements and transponder shipments go to the correct location. If you sell your vehicle, you can remove it from your account and add a new one. If you're no longer using SunPass, you can close your account online, though any remaining balance will be refunded to your original payment method within 30 days.

What to do if your transponder stops working

If tolls are being charged to your Pay-by-Plate account even though you have a transponder mounted, the transponder may not be reading correctly. Check that it's mounted in the correct location on your windshield (usually the upper right corner, away from tinted areas). Make sure it's not blocked by a sunshade, sticker, or dirt.

If the transponder still isn't working, contact SunPass Customer Service at 1-888-865-5352 or visit a Customer Service Center in person. They can test your transponder and replace it if it's defective. Replacement transponders are usually free if the original was faulty. While you wait for a replacement, your account will continue to work on Pay-by-Plate, though you'll pay the higher rate until the new transponder is active.

Frequently Asked Questions

Can I use someone else's SunPass account to pay my tolls?

No. A SunPass account is tied to a specific vehicle registration. If you're driving a vehicle registered to someone else, you'll need to use their transponder or pay by plate. You can't transfer a transponder between vehicles unless you update the account with the new vehicle's information first.

What happens if my account balance reaches zero while I'm driving?

If you have a transponder, the system will still read it and charge the toll, but your account will go negative. You'll receive a notice to replenish your account. If you're using Pay-by-Plate, you'll be billed by mail at the higher rate. Either way, add funds as soon as you can to avoid late fees or service interruption.

Can I get a refund if I overpay my SunPass account?

Yes. If your account has a credit balance when you close it, SunPass will refund the remaining balance to your original payment method within 30 days. If you straightforward want to reduce your balance without closing the account, contact Customer Service to request a refund.

Do I need a separate SunPass account for each vehicle I own?

No. You can add multiple vehicles to a single account, each with its own transponder. This is useful if you have a household with several cars. Each transponder is linked to a specific vehicle registration, but they all draw from the same account balance.

Is there a customer service phone number if I have questions?

Yes. Call SunPass Customer Service at 1-888-865-5352. They're available Monday through Friday, 8 a.m. to 6 p.m. Eastern time, and Saturday 9 a.m. to 5 p.m. You can also visit a Customer Service Center in person if you prefer to handle your account face-to-face.
