What you're buying when you purchase a SunPass

A SunPass is a small electronic device that mounts on your windshield and automatically pays tolls as you drive through toll plazas on Florida's highways. When you buy a SunPass transponder, you're purchasing the device itself — not a prepaid account or a service plan. The transponder is a one-time purchase, though you'll need to set up a separate account and fund it with money to pay tolls.

The device works by communicating with toll readers at highway plazas. As you pass through, the reader identifies your transponder and deducts the toll amount from your account. You don't stop, don't hand over cash, and don't need to do anything — the system handles it all. If your account runs low on funds, you can add money online, by phone, or through the mail.

SunPass is operated by the Florida Department of Transportation and works on most of Florida's toll roads, including the Florida Turnpike, Sunshine Skyway Bridge, and Beachline Expressway. Some toll plazas also accept other transponders like E-Pass, but SunPass is the most widely accepted across the state.

Key Takeaways

  • You can buy a SunPass transponder directly from the official SunPass website, by phone at 1-888-865-7827, or at retail locations including Publix Super Markets and Winn-Dixie stores.
  • A new transponder costs between $25 and $35, depending on the type and where you purchase it; this fee includes the device but not the toll money you'll load into your account.
  • After purchasing the device, you must create an account online or by phone and add funds before you can use it on toll roads.
  • You can use the same transponder for multiple vehicles by switching it between windshields, though only one vehicle can use it at a time.
  • If your transponder stops working or is damaged, you can request a replacement through your account; some replacements are free, while others may have a small fee.

Where to buy a SunPass transponder

The official SunPass website (sunpass.com) is the most direct route. You can order online and choose to have the transponder mailed to you or pick it up at a SunPass customer service center. Shipping typically takes five to seven business days, so order ahead if you need it by a specific date.

You can also call SunPass customer service at 1-888-865-7827 to order by phone. A representative can answer questions about which transponder type suits your needs and process your order over the call. They can also arrange for pickup at a local center if you prefer not to wait for mail delivery.

Retail locations throughout Florida sell SunPass transponders without requiring an online order. Publix Super Markets, Winn-Dixie, and some Target stores stock them. Prices at retail locations may differ slightly from the official website, so compare before you buy. Retail purchases let you take the device home when ready and set up your account that same day.

Cost of a SunPass transponder and what's included

A standard SunPass transponder costs between $25 and $35 at most retailers and on the official website. The exact price depends on the type of transponder — basic models cost less than specialty versions designed for motorcycles or RVs. This purchase price covers only the physical device; it does not include any toll money.

When you buy the transponder, you receive the device itself, a windshield mounting bracket, and instructions for setting up your account. Some retailers bundle the transponder with a prepaid toll credit — for example, a $25 transponder might come with $10 in toll credit already loaded. Check the product description before you buy to see whether credit is included.

After you own the transponder, you'll need to fund your account separately. Most people start with $25 to $100 in toll credit, depending on how often they use toll roads. There is no monthly fee for maintaining a SunPass account, and you only pay when you use the tolls.

Setting up your account after purchase

Once you have the physical transponder, you must create an account to use it. Go to sunpass.com, click "Create Account," and enter your name, address, email, and phone number. You'll also provide your vehicle information — license plate, vehicle type, and VIN. This registration links your transponder to your account.

Next, add funds to your account. You can pay by credit card, debit card, or bank transfer. Most people set up automatic replenishment, which adds money to the account when the balance drops below a certain amount — for example, adding $50 when your balance falls below $10. Automatic replenishment ensures you never run out of toll credit while driving.

After your account is funded, your transponder is ready to use. It typically activates within 24 hours of account creation. Keep the transponder mounted on your windshield, and tolls will be deducted automatically as you pass through toll plazas.

Transponder types and which one to choose

SunPass offers several transponder types designed for different vehicles. The standard transponder works for most cars, SUVs, and light trucks. A motorcycle transponder is smaller and designed for two-wheeled vehicles. A Class 5/6 transponder is for larger vehicles like RVs, box trucks, or commercial vehicles and may have different toll rates.

Choose based on the vehicle you'll use most often on toll roads. If you own multiple vehicles and want to use tolls in each, you can buy multiple transponders and link them to the same account. Alternatively, you can move a single transponder between vehicles by remounting it on different windshields, though only one vehicle can use it at a time.

If you're unsure which type you need, call 1-888-865-7827 and describe your vehicle. A representative can recommend the right transponder and explain any differences in toll rates for your vehicle class.

Using your transponder on Florida toll roads

Once your transponder is mounted and your account is active, using it is automatic. As you approach a toll plaza, stay in any lane marked for electronic toll collection. Your transponder communicates with the reader, and the toll is deducted from your account. You'll see a green light or hear a beep confirming the transaction — no need to stop or interact with anything.

If you accidentally drive through a toll plaza without a working transponder, or if your account balance is too low, you'll receive a violation notice. The toll amount plus a violation fee will be charged to your account if you have one on file. If you don't have an account, the toll authority will send you a bill by mail.

Check your account online regularly to monitor your balance and transaction history. The SunPass website shows every toll you've paid, the date, location, and amount. This record is useful for tracking expenses or disputing a charge if something seems wrong.

Replacing or updating your transponder

If your transponder is damaged, lost, or stops working, you can request a replacement through your SunPass account. Log in, go to the device management section, and select "Request Replacement." Some replacements are free if the device failed due to a manufacturing defect. If you lost the transponder or damaged it through misuse, there may be a replacement fee of $5 to $10.

Replacement transponders are mailed to you within five to seven business days. Your account balance transfers to the new device automatically, so you don't lose any toll credit. If you need a replacement urgently, call customer service to ask about expedited shipping or local pickup options.

You can also update your account information — such as your address, email, or vehicle details — anytime through the website or by calling customer service. These changes take effect when ready and don't affect your transponder or account balance.

Frequently Asked Questions

Can I use a SunPass transponder in other states?

SunPass works on Florida toll roads only. If you travel to other states with toll roads, those states have their own systems — for example, Georgia uses Peach Pass, and the Northeast uses E-ZPass. Some rental car companies offer transponders for out-of-state travel, or you can pay tolls manually at those plazas.

What happens if my account balance runs out while I'm driving?

If your balance is too low to cover a toll, your transponder will still read at the plaza, but the transaction may be declined. You'll receive a violation notice by mail with instructions to pay the toll plus a fee. Set up automatic replenishment to avoid this — the system will add funds before your balance reaches zero.

Can I transfer my SunPass to someone else?

You can give the physical transponder to another person, but they'll need to create their own SunPass account and link the device to it. The transponder itself isn't tied to your name — only your account is. The new owner can register it in their name and use it when ready.

Do I need a SunPass if I only use tolls occasionally?

You don't need one, but it's often cheaper than paying cash at toll booths. Cash tolls are typically 25 to 50 percent higher than electronic tolls. If you use tolls more than a few times a year, the transponder pays for itself through the discount. If you rarely use tolls, paying cash at the booth may be simpler.

How long does a SunPass transponder last?

Most transponders last five to seven years with normal use. The battery inside the device eventually wears out, and the device stops communicating with toll readers. When that happens, request a replacement through your account. There's no need to replace it before it stops working — use it until it fails.
