About E-ZPass

E-ZPass is an automated toll collection system that allows individuals and businesses to pay tolls in Maryland and other states where E-ZPass is accepted.

E-ZPass has two components:

  • An electronic transponder mounted on your vehicle’s windshield or license plate
  • An overhead antenna at the toll facility

Each time you travel through a participating toll facility, the overhead antenna reads the transponder attached to your vehicle and deducts the toll from your prepaid E-ZPass account.

Maryland drivers with an E-ZPass pay less each time they use a toll facility. To calculate tolls for your trip, visit the Toll Rate Calculator.

In addition, you may be eligible for one or more of our E-ZPass Discount Plans, which could save you even more.

In Maryland, windshield-mounted E-ZPass transponders are free. License plate mounts are available for a modest fee.

There are no monthly or annual fees for Maryland residents. Out-of-state residents who have fewer than three trips at Maryland toll facilities per month may be assessed a monthly maintenance fee.

Each transponder is connected to an E-ZPass account. When you sign up, you will be required to deposit $25 into your E-ZPass account. The entire amount is available to pay tolls as you use our facilities and will only be deducted from your account based on toll usage.

Sign up on this website and an E-ZPass transponder will be mailed to you in 5-7 business days with no cost for shipping.

Or, you can buy a prepackaged E-ZPass On the Go transponder at participating retailers. On the Go transponders come pre-loaded with $25. The pre-loaded $25 will be applied to toll usage. Register your transponder on this website within 7 days of first use. Once registered, E-ZPass On the Go works just like a traditional E-ZPass.

E-ZPass On the Go is a packaged transponder with a pre-paid toll balance of $25 that’s available to use immediately.

You must register your transponder within 7 days of its first use. If you fail to register your transponder within 7 days, a Notice of Toll Due will be sent to the address associated with the vehicle’s registration at the time the transaction occurred. You will be responsible for paying any tolls you have accrued at the Video Toll rate.

Access instructions on how to mount your transponder.

You must install your windshield or license plate mounted transponder exactly as shown in the instructions.

Placing the transponder on the sun visor, rear-view mirror, in your glovebox, on your dashboard, seat, or in your hand may work occasionally, but doing so could result in toll-evasion violations, administrative fees, or higher tolls.

Customers should check with their vehicle manufacturer for instructions on mounting transponders on specialty windshields. Please be mindful not to install your transponder in the tinted portion of your windshield.

You can log in to your account or call 1-888-321-6824 to access our automated phone system and check your account balance.

You can make convenient, automatic payments to your account by credit card, or you can replenish your account by check, money order or cash.

Automatic credit card payments process when the balance in your account dips below a certain threshold. This means you’ll never have to worry about having insufficient funds in your account.

  • If you are a private account holder who pays by credit card, your account will be replenished whenever your balance falls below your account’s re-billing threshold.
  • Business accounts are replenished when the account balance reaches approximately 25 percent of your advance payment amount.

As a convenience for our credit card customers, we automatically adjust your replenishment amounts to reflect your average monthly usage. This helps to ensure that your replenishments are sufficient to cover your toll usage for an entire month and minimizes the need to charge your account multiple times in one month.

To pay by check or money order, visit one of our Customer Service Center locations during hours of operation or use one of the convenient, 24/7 drop boxes available at the front of each center at MDTA toll facilities. Payments received after normal business hours will be processed on the next business day. All check or money order payments must include account number, license plate number, name and contact number.

Customers may also send payment to:

Maryland Service Center
P.O. Box 5060
Middle River, MD 21220-5060

To pay with cash, please visit one of our customer service centers.

Please note that replenishment funds are not automatic. It takes 24 hours for the replenishment funds to be available for in-state toll usage or 48 hours for out-of-state toll usage.

From time to time, you may need to update the credit card or bank account information that’s associated with your E-ZPass account:

  • Updated credit card expiration date
  • New credit card
  • Lost credit card
  • New address associated with your credit card or bank account
  • Updated bank account

Log in to your account to update your payment information. You may also visit one of our Customer Service Centers or call the E-ZPass Maryland Customer Information Center at 1-888-321-6824.

Do not use your E-ZPass until your account has been replenished. Remove the E-ZPass transponder from your vehicle or place it in the “read prevention” bag.

Auto Replenishment-Private Accounts: If you are a private account holder and are a credit card or ACH customer, your account will be replenished when your balance falls below your low balance account threshold. You many need to update your auto replenishment method, credit card (number or expiration date) or ACH.

Auto Replenishment-Business Accounts: If you are a business account holder and are a credit card or ACH customer, your account will be replenished whenever your account balance is approximately 25 percent of your advanced payment amount (low balance threshold).

As an additional convenience for our valid credit card customers, we will automatically adjust your replenishment amounts to reflect your average monthly usage. This helps to ensure that your account balance has sufficient funds to cover your toll usage.

In order to avoid running out of money in your account, call the Customer Information Center at 1-888-321-6824 to inquire about switching to automatic credit card replenishment.

Your E-ZPass statement is your receipt. Refer to your statement for the amount, date, time and location of each toll transaction. You can also access this information by logging in to your account or by calling 1-888-321-6824 and accessing our automated phone system.

You may access your account and reset your PIN on the login page.  If you do not have access to your account, please call 1-888-321-6824 and have your personal information ready to provide to a Customer Service Representative.

Vehicles and Transponders

If your transponder is not working but your account is in good standing, first check to see that your transponder is properly affixed to your vehicle. If so, please contact us for assistance.

You may log in to your account and report the transponder lost or stolen.

During regular business hours, you may contact customer service to report the transponder lost or stolen. If outside of regular business hours, please make sure to report the lost or stolen transponder to your local police department and follow up with E-ZPass Maryland customer service during regular business hours.

Please note customers will be responsible for tolls incurred prior to reporting the transponder lost or stolen.

DO NOT STOP OR ATTEMPT TO BACK UP. Your license plate will be recorded using the Video Tolling system and the registered owner of the vehicle will receive a Notice of Toll Due (NOTD) in the mail.

Note that you will be responsible for paying the Video Toll rate for this transaction.

Don’t use your transponder if:

  • You have reported your transponder as lost or stolen but later find it, call our Customer Information Center for further instructions. It may be possible to return your transponder to “active status”.
  • You know that you do not have sufficient funds in your 
    E-ZPass account.
  • You are using a vehicle that requires a special load permit.

You may request up to 10 transponders as long as you have 10 vehicles listed in your Private Account.

There is no limit to the number of transponders or vehicles you can request for a Business Account.

An E-ZPass transponder will be mailed to you in 5-7 business days with no cost for shipping.

If you need a transponder sooner, consider picking up an
E-ZPass On the Go from one of our participating retailers.

If you’re pulling a camper or trailer, you may use your vehicle on Maryland toll roads. However, you will be charged the Video Toll rate for the actual number of axles.

Please add the license plate of your camper or trailer to your account.
