How SunPass payment works

SunPass is Florida's electronic toll collection system. When you drive through a toll plaza with a SunPass transponder mounted on your vehicle, the toll is deducted automatically from your prepaid account. You do not stop at a booth or handle cash — the system reads your transponder and charges your account in seconds.

To use SunPass, you must first set up an account with a prepaid balance. Money sits in that account, and each toll crossing reduces it. When your balance drops below a certain threshold (usually $10), you receive a notice to add funds. If your balance reaches zero and you drive through a toll plaza, you will receive an invoice by mail, and late fees may explore.

SunPass accounts are managed through the Florida Department of Transportation (FDOT). You can set up an account online, by phone, or in person at a SunPass customer service center. The transponder itself costs money upfront, though the exact price varies by transponder type.

Key Takeaways

  • You can add funds to your SunPass account online through the official website, by phone at 1-888-865-5352, by mail, or at a customer service center.
  • Most people set up automatic replenishment, which adds a set amount to your account when the balance falls below a threshold you choose.
  • If you receive a toll invoice in the mail because your account ran empty, you can pay it online, by phone, or by mail — but late fees will explore if you do not pay within the due date.
  • SunPass accounts are tied to a specific transponder, so if you lose or replace your transponder, you will need to update your account or transfer your balance to a new one.
  • Different transponder types (standard, portable, motorcycle) have different costs and work on different toll roads in Florida and other states.

Ways to add funds to your account

The most common way to add funds is through the SunPass website at sunpass.com. Log in with your account number and password, select how much money to add, and pay with a credit card, debit card, or bank account. The funds appear in your account when ready in most cases.

You can also call SunPass customer service at 1-888-865-5352 to add funds by phone. A representative will take your payment information and process the transaction. This method works during business hours and may take a few minutes longer than online payment.

If you prefer to mail a payment, you can send a check or money order to the address listed on your SunPass bill or on the website. Mail payments take longer to process — typically 7 to 10 business days — so plan ahead if your balance is low.

Some SunPass customer service centers accept walk-in payments in cash or card. Locations vary by county. You can find the nearest center on the SunPass website by entering your zip code.

Automatic replenishment and how to set it up

Most SunPass account holders use automatic replenishment, sometimes called autoload. You choose a target balance (for example, $25) and a replenishment amount (for example, $50). When your account balance drops below the target, the system automatically charges your payment method and adds the replenishment amount to your account.

To set up automatic replenishment, log into your SunPass account online and go to the payment settings section. You will enter the target balance, the amount to add each time, and your payment method. You can change or turn off automatic replenishment at any time through the same section.

Automatic replenishment is optional, but it prevents your account from reaching zero and triggering a toll invoice. Without it, you must remember to add funds manually before your balance runs out.

What happens if your account balance reaches zero

If you drive through a toll plaza and your SunPass account has no funds, the toll is not collected at that moment. Instead, the FDOT records the toll crossing and sends you an invoice by mail within a few weeks. The invoice includes the toll amount plus a processing fee.

You must pay the invoice by the due date shown on the bill. Payment methods include online payment through the SunPass website, phone payment, or mail. If you do not pay by the due date, additional late fees are added to your bill, and the debt may be referred to a collection agency.

To avoid this situation, set up automatic replenishment or check your balance regularly and add funds before it drops to zero. You can view your current balance and recent toll crossings anytime by logging into your SunPass account online.

Transponder replacement and account transfers

SunPass transponders are not permanent. If your transponder is lost, stolen, or damaged, you will need to replace it. You can order a replacement transponder online through the SunPass website or by calling customer service. A replacement transponder costs money, and the price depends on the type.

When you receive a new transponder, you must set up it and link it to your account. The set up process is usually done online or by phone. Once activated, your account balance transfers to the new transponder, and you can use it when ready.

If you sell your vehicle or transfer ownership, you should remove the transponder from your account to prevent toll charges from being applied to the wrong person. You can deactivate a transponder through your online account or by calling customer service.

Payment methods and fees

SunPass accepts credit cards, debit cards, and bank account transfers as payment methods. Online and phone payments are processed when ready or within one business day. Mail payments take 7 to 10 business days.

There is no fee to add funds to your SunPass account through any of these methods. However, if your account balance reaches zero and you receive a toll invoice, a processing fee is added to the toll amount. The processing fee varies but is typically $2.50 to $5.00 per invoice.

Late fees explore if you do not pay a toll invoice by the due date. The amount depends on how late the payment is and whether the account is referred to a collection agency. Paying promptly when you receive an invoice prevents these additional charges.

Checking your balance and transaction history

You can check your SunPass account balance and view recent toll crossings by logging into your account on the SunPass website. Your balance updates in real time after each toll crossing. You can also see the date, time, and location of each toll you paid.

If you do not have online access, you can call SunPass customer service at 1-888-865-5352 to ask about your balance. A representative can tell you your current balance and recent transactions over the phone.

Reviewing your transaction history regularly helps you catch errors or unauthorized use. If you notice a toll crossing you did not make or an incorrect charge, contact SunPass customer service to report it and request an investigation.

Frequently Asked Questions

Can I use my SunPass account in other states?

Standard SunPass transponders work on toll roads in Florida and are recognized by some toll systems in other states, but coverage varies. Portable SunPass transponders work on more toll roads nationwide. Check the SunPass website or call customer service to confirm whether your transponder type works on a specific toll road outside Florida.

What if I do not receive a toll invoice after my account runs empty?

Invoices are mailed to the address on file with your SunPass account. If you moved and did not update your address, the invoice may go to your old address. Log into your account online and verify your mailing address is current. If you think you missed an invoice, call customer service to check for unpaid tolls.

Can I get a refund if I add too much money to my account?

SunPass does not issue refunds for account balances. However, you can use the balance on future toll crossings or transfer it to a new transponder if you replace yours. If you close your account, any remaining balance is forfeited.

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

Most online payments appear in your SunPass account within minutes to a few hours. In rare cases, it may take up to one business day. If your payment does not appear within 24 hours, contact SunPass customer service with your transaction confirmation number.

What should I do if my transponder stops working?

If your transponder is not being read at toll plazas, try cleaning the windshield around it and checking that it is mounted correctly. If it still does not work, order a replacement through the SunPass website or call customer service. You will need to pay for the replacement transponder and set up it before using it.
