Maryland E-ZPass customer service helps drivers solve toll account issues, fix transponder problems, and resolve billing disputes across the state. The Maryland Transportation Authority operates the E-ZPass system in Maryland and runs the support line, online portal, and walk-in service centers.
Drivers on Maryland toll roads, including the I-95 Express Toll Lanes, the Fort McHenry Tunnel, the Baltimore Harbor Tunnel, and the Bay Bridge, can reach support by phone, online, or in person. Support covers balance checks, payment updates, transponder replacements, and violation appeals.
Maryland E-ZPass Phone Number and Support Hours
Call 1-888-321-6824 to speak with a Maryland EZ Pass representative. This toll-free number routes callers to the Maryland Transportation Authority customer service center in Baltimore. The line handles account changes, billing questions, transponder replacements, and violation disputes in one call.
Call volume peaks on Monday mornings and the days after major holidays. Early morning calls on weekdays connect faster than afternoon calls. Hold times run under five minutes during off-peak hours and stretch past twenty minutes on busy days.

Maryland E-ZPass Account Login Help
Sign in to your Maryland E-ZPass account at ezpassmd.com to check balances, view statements, update vehicles, and change payment types. The login screen asks for a username and password set up during account registration.
login problems include:
- Forgotten username: Click “Forgot Username” on the login page. The system sends a recovery email to the address on file.
- Forgotten password: Click “Forgot Password” and reset it through the emailed link.

First-time users need an account number from a transponder, a recent toll statement, or a violation notice. New accounts require a license plate, payment type, and contact details. The portal walks new users through each step.
Maryland E-ZPass Payment Types and Balance Checks
Maryland EZ-Pass accounts accept major credit cards, debit cards, and ACH bank transfers. Prepaid accounts require a balance to cover tolls. The system deducts tolls automatically as vehicles pass through toll plazas.
Check your balance three ways:
- Log in to the online portal and view the dashboard
- Call 1-888-321-6824 and use the automated phone menu
- Use the Maryland E-ZPass mobile app for iOS and Android
Low balance alerts trigger when funds drop below a set threshold. Drivers set the threshold in account settings. Replenish prepaid accounts by linking a bank account or credit card for auto-replenish, or by making one-time payments online.
Failed payments result in toll violations and account suspension. Update expired cards right away to avoid missed tolls. The system sends email notices before each scheduled payment.
Transponder Troubleshooting and Replacement in Maryland
A working EZ-Pass transponder mounts on the windshield and signals the toll system as the car passes through plazas. transponder issues include a dead battery, a cracked case, or a device not reading at toll booths.
Troubleshoot a non-working transponder with these steps:
- Check the mounting position. Place the device behind the rearview mirror on the windshield.
- Inspect the battery. Most Maryland E-ZPass transponders have indicator lights that signal low battery.
- Clean the device. Dirt on the transponder face blocks the signal.
- Test at a different toll plaza to rule out a plaza-specific issue.
If the transponder still fails, call customer service or visit a service center for a replacement. Standard transponder replacements cost $25. Interior switchable transponders cost more. Lost or stolen transponders get deactivated to prevent unauthorized use.
Replacement transponders ship to the address on file within 5-7 business days. In-person pickup at a service center provides same-day replacement. Bring the old transponder and a photo ID for the swap.
Maryland Toll Violation Assistance and Dispute Resolution
Unpaid tolls in Maryland lead to violation notices with added fees. The first notice arrives by mail and includes the toll amount, the unpaid fee, and a deadline to respond. Ignoring the notice escalates the case to the Maryland District Court.
Dispute a violation through these channels:
- Online: Submit a dispute form through the Maryland EZPass portal under “Violations”
- Phone: Call 1-888-321-6824 and speak with a violation specialist
- Mail: Send a written dispute with supporting documents to the address on the notice
Dispute cases need evidence. Useful documents include toll receipts, transponder activity logs, vehicle registration records, and photos of the transponder mounted in the car. The Maryland Transportation Authority reviews disputes and sends a written decision within 30-45 days.
Pay outstanding tolls and fees right away to stop extra charges. Most disputes resolve faster when the toll amount gets paid during the review period. Refunds follow successful disputes through the original payment type within 30 days.
Maryland E-ZPass Service Center Locations
Maryland EZPass runs walk-in service centers across the state. Visit a center for transponder pickup, account changes, payment processing, and in-person dispute help. Centers also handle account closures and balance refunds.
Service center hours vary by location. Most centers open Monday through Friday from 8:30 AM to 4:30 PM. Some centers add Saturday hours from 9:00 AM to 1:00 PM. Check the website for current schedules at each location.
Major service center locations include:
- Baltimore area (4330 Broening Highway, near the Fort McHenry Tunnel)
- Anne Arundel County (near the Bay Bridge)
- Montgomery County (near the I-270 corridor)
- Other regional centers along major toll corridors
Bring a photo ID, the transponder, and a recent toll statement when visiting. Service center staff handle tasks that online account features cannot process, such as switching account types or resolving complex billing errors.
Maryland E-ZPass Email, Chat, and Social Media Support
Email support handles non-urgent account questions. The Maryland E-ZPass contact email appears on the official website under the “Contact Us” section. Expect a reply within 2-3 business days. Email works best for general account questions, documentation submissions, and follow-ups on existing cases.
For real-time help, the live chat feature on the Maryland EZPass website connects drivers to support agents during business hours. Chat covers the same topics as phone support but adds a written record of the conversation. Chat transcripts arrive by email after the session ends.
Social media accounts on Facebook and X (Twitter) post service alerts and outage notices. Direct messages on these platforms route to the customer service team. Expect slower replies on social media than on phone or chat, but the public posts help all drivers stay updated.

Maryland E-ZPass Customer Service FAQ
Drivers ask these questions most often when contacting Maryland EZPass customer service. The answers cover the most common account, billing, and transponder issues, plus the steps to fix each one. Each answer includes the direct contact method for faster help.
How do I check my Maryland E-ZPass balance without logging in?
Call 1-888-321-6824 and use the automated menu to check your balance. The system asks for your account number or transponder ID and reads the current balance aloud. Balance checks through the phone line work 24/7, even when agents are offline. The mobile app and online portal also show real-time balances after login. For prepaid accounts, the auto-replenish threshold appears in the same menu.
What happens if I drive through a Maryland toll without an E-ZPass?
The system photographs the license plate and mails a video toll bill to the registered owner. Video tolls cost more than EZPass rates because of the added processing fee. Unpaid video tolls turn into violations with extra fees after 30 days. Pay video tolls online or by mail within 30 days to avoid escalation. Setting up an EZ Pass account stops video toll bills for the registered vehicle.
How long does it take to get a replacement E-ZPass transponder in Maryland?
Mailed replacements arrive in 5-7 business days at the address on file. In-person pickups at a service center happen the same day, with most locations completing the swap in under 15 minutes. The $25 replacement fee applies to each new transponder. Report lost devices right away to deactivate them and prevent toll charges on the missing unit. Express shipping is not available for standard transponder orders.
Can I use my Maryland E-ZPass in other states?
Yes. EZ Pass works in 19 states across the Midwest and East Coast, plus parts of Canada. The same transponder and account cover tolls everywhere EZ-Pass is accepted. Out-of-state tolls post to your Maryland account at the local rate. Discounts vary by state, so check each toll authority’s rate sheet before long trips. Some out-of-state toll plazas still accept cash as a backup.
How do I dispute a toll violation in Maryland?
File a dispute online through the Maryland EZPass portal or call 1-888-321-6824 to start a violation case. Submit copies of any proof, such as transponder records, receipts, or registration documents. The Maryland Transportation Authority reviews disputes and sends a written response within 30-45 days. Pay the original toll amount during the dispute to show good faith and speed up the review. Successful disputes refund the fees within 30 days.
Why does my Maryland E-ZPass account show a negative balance?
A negative balance means recent tolls exceeded the prepaid amount. The system deducts tolls as the car passes through plazas, so timing differences can cause brief negative balances before auto-replenish kicks in. Auto-replenish adds funds from the linked payment type when the balance drops below a set amount. Update the linked payment type if auto-replenish fails repeatedly. Manual payments fix a negative balance right away.
How do I close my Maryland E-ZPass account?
Call 1-888-321-6824 or visit a service center to close the account. Bring a photo ID and the transponder. Remaining balances refund to the original payment type within 30 days of closure. Account closures stop future toll charges but do not erase past violations or unpaid fees. Settle all open violations before closing the account to avoid collection actions. The Maryland Transportation Authority keeps closed account records for seven years.
