How to Update License Plate on SunPass, E-PASS & LeeWay 2026: Step-by-Step Florida Guide

You can replace your Florida license plate, update your registration, and still receive a toll invoice. The missing step is often your toll account.

SunPass, E PASS, and LeeWay do not automatically know that the state issued you a new plate. Until you add it yourself, a toll camera may photograph a plate that has no connection to your prepaid account.

Sometimes your transponder still reads and nothing goes wrong. But if it does not, the trip may be billed at a higher plate rate. You could also receive administrative fees.

The fix is usually quick. The right steps depend on your account, your transponder, and whether you have already traveled.

Find the Instructions for Your Situation

You do not need to follow every step in this guide. Start with the situation that sounds like yours.

Before you make the change, it helps to understand why the plate matters.

Why Your Toll Account Still Needs the Correct Plate

Your transponder is normally the first way a toll system identifies your account. Your license plate provides another way to match the vehicle when the transponder does not read.

That backup can fail if the plate in your account is outdated. A transponder may not read because it is damaged, mounted incorrectly, or blocked by certain windshield materials.

When neither the transponder nor the plate produces a valid match, the trip may move into plate based billing.

The potential costs vary by agency:

• SunPass: A Toll by Plate invoice includes a $2.50 administrative fee per invoice, according to the official SunPass frequently asked questions.
• E PASS: Pay By Plate uses a higher rate than the electronic E PASS rate.
• LeeWay: Pay By Plate transactions include a $3 administrative fee per toll. Current rates are listed on the official Lee County toll information page.

For a two axle vehicle, that LeeWay fee can turn a $2 Cape Coral or Midpoint bridge toll into a $5 charge. A $6 Sanibel Causeway toll can become $9.

Updating your registration with the state does not complete this step. The SunPass Customer Agreement tells account holders to update vehicle and plate information before using a toll facility.

Gather These Details Before You Log In

Take a photo of the new plate before you start. It is easier to check the characters against a photo than to keep walking back to your car.

You may need:

• Your account login information
• The new plate number and issuing state
• The old plate number
• The vehicle make, model, year, and color
• The number of axles
• The transponder number
• The date the new plate became effective
• Your rental agreement, if the vehicle is a rental

Check similar looking characters carefully. The letter O and number 0 are easy to confuse. So are the letter I and number 1.

For SunPass, enter the plate characters without spaces or special symbols. Select the issuing state separately.

How to Update a License Plate on SunPass

SunPass lets you update vehicle information through its website or mobile app. Start with the standard edit option if you are correcting an existing record.

Make a Standard SunPass Update

These steps follow the current instructions in the SunPass frequently asked questions.

1. Sign in at SunPass.com or open the mobile app.
2. Select Transponders and Vehicles.
3. Find the correct vehicle.
4. Select Edit in the Vehicle section.
5. Enter the new plate number.
6. Confirm the issuing state and plate type.
7. Review the vehicle make, model, year, and color.
8. Save the change.
9. Confirm that the correct transponder is still linked to the vehicle.

Save a screenshot of the updated record. It can help if you later need to question a transaction.

Remove and Add the Vehicle If a Full Replacement Is Needed

A completely new plate or vehicle may need a new record. This is also the approach SunPass recommends for an existing customer who receives an invoice because the plate was missing from the account.

1. Open Transponders and Vehicles.
2. Remove or deactivate the outdated vehicle record.
3. Select Add Another Vehicle.
4. Enter the new plate and vehicle details.
5. Mark the vehicle as a rental or trailer if applicable.
6. Select the effective start date and time.
7. Link the vehicle to the correct transponder.
8. Save and review the record.

A license plate can be actively subscribed to only one SunPass account at a time. If the system says the plate belongs to another account, resolve that conflict before traveling.

What to Do If You Already Drove or Received an Invoice

Do not simply choose today’s date if you are trying to resolve earlier toll activity.

SunPass tells existing customers with an invoice to add the vehicle and use the earliest transaction date on the invoice as the effective start date. That is different from the date the invoice was printed or delivered.

The agency’s vehicle upload guidance also states that an effective start date can be backdated by up to 45 days.

Make sure your account has enough money to cover the charges. SunPass says eligible invoice amounts are deducted from the account within 48 hours after the correct steps are completed.

If the debt has already moved to collections or produced a registration stop, follow the instructions on that notice. You may need to work with both SunPass and the assigned collection agency.

How to Update a License Plate on E PASS

E PASS lets you change vehicle information through its online dashboard or mobile app. The process is straightforward, but you should also check the transponder connected to the vehicle.

Update Your Plate Online

Use these steps in a browser:

1. Sign in through the Central Florida Expressway Authority website.
2. Open your E PASS account dashboard.
3. Find the vehicle information area.
4. Select the edit icon beside the license plate.
5. Enter the new plate number and issuing state.
6. Review the vehicle make, model, year, color, and axle count.
7. Save the record.
8. Check the transponder section to confirm the correct device is assigned.

The agency shows this process in its official guide to managing an E PASS account.

Update Your Plate in the Mobile App

The app is useful if you are already sitting in the vehicle and have the plate details with you.

1. Open the E PASS Toll App and sign in.
2. Go to Vehicles.
3. Select the vehicle or transponder you want to change.
4. Choose Update Vehicle.
5. Enter the requested information.
6. Save the change.
7. Return to the vehicle list and verify the new plate.

If you move a portable Uni transponder, update the vehicle before driving. CFX also says the Uni should be moved only to a vehicle of the same class, such as another two axle vehicle.

A newly issued E PASS transponder can take up to 24 hours to be read on expressways operated by other agencies. Plan ahead if your first trip will be outside the CFX network.

How to Update a License Plate on LeeWay

LeeWay needs a different approach when a plate is already assigned to an active transponder. Its account system tells customers to contact LeeWay for directions in that situation. The Vehicle Change Form is the clearest way to request the update.

Start with the official LeeWay Vehicle Change Form.

Then complete these steps:

1. Enter your name and contact information.
2. Add your LeeWay account number if you know it.
3. Complete the old vehicle information section.
4. Enter the new plate and vehicle details.
5. Confirm that the vehicle matches the transponder’s axle classification.
6. Select the correct transponder option.
7. Sign and date the form.
8. Include any documents required for your account or discount program.

The form also tells LeeWay what you need for the replacement vehicle.

• If you use a LeeWay Mini sticker, request a replacement sticker for installation in the new vehicle.
• If you use a reusable hard case transponder, follow the form’s instructions for mounting supplies.

Drivers enrolled in discount programs should check whether current vehicle registrations are required. This is especially important when changing vehicles in a multiple vehicle discount arrangement.

Email the completed form to [email protected]. You can also fax it to 239 278 7854 or deliver it to:

LeeWay Service Center
1366 Colonial Blvd.
Fort Myers, FL 33907

For help before submitting the form, call 239 533 9297.

Check Whether Your Transponder Can Move to the New Vehicle

Changing the plate does not always mean you can keep the same transponder. Some devices are portable, while others stop working when removed.

If you are choosing a new SunPass device, this guide explains the difference between SunPass Mini and SunPass PRO.

Once you know how your device works, the remaining special cases are much easier to handle.

How to Handle a Rental Car

Wait until pickup to get the rental plate number. Take a clear photo of the rear plate and confirm the issuing state.

For SunPass:

1. Select Add Another Vehicle.
2. Enter the rental plate and vehicle information.
3. Check the Rental Vehicle box.
4. Add the start and end dates and times.
5. Save the record.
6. Remove your portable transponder when returning the car.

The end time matters. It defines when the rental plate should stop being connected to your account.

For E PASS, update the vehicle information before using a portable Uni on toll roads. Remove the rental from your account after returning it.

Also read the toll section of your rental agreement. The rental company may have its own billing program and service fees. Using your personal account does not automatically cancel that arrangement.

What to Do About Temporary Tags

A newly purchased vehicle may have a temporary tag before its permanent plate arrives. If you plan to use your personal transponder, add the temporary vehicle information as soon as your account allows it.

Keep the transponder properly mounted. This gives the toll system a working account identifier even if the temporary plate is difficult to match by camera.

When the permanent plate arrives, update the record immediately. Do not leave the temporary tag active indefinitely.

If the portal will not accept the temporary number, contact the agency before relying on plate based backup billing.

Avoid Carrying Two Active Transponders

Using several toll accounts does not mean you should carry all of their devices in one vehicle.

Two active transponders can be read during the same trip. That can produce duplicate charges.

Choose the transponder you want to use. Remove portable devices you do not need, or place them in a proper radio frequency shield bag. SunPass specifically warns customers about this issue in its official frequently asked questions.

If you rely on a local discount, also confirm that your chosen transponder qualifies for it.

What to Check Before Your Next Toll Trip

A final review takes less than a minute and can catch an incomplete update.

Open your account and confirm:

• The new plate appears correctly
• The issuing state is correct
• The old vehicle or plate is no longer active
• The right transponder is linked
• The transponder is mounted properly
• Rental dates and times match your agreement
• Your payment method and balance are current

If you changed your plate today, update the toll account before your next trip. If you already traveled, check the transaction dates now. The sooner you correct the record, the more options you are likely to have for resolving any missed tolls.
