E‑ZPass Maryland — Customer Service: expert guide

Overview of E‑ZPass Maryland customer service

E‑ZPass Maryland is administered by the Maryland Transportation Authority (MDTA). For customers this means one centralized program that handles account enrollment, transponder issuance, billing, violations and refunds across Maryland toll facilities and interoperable systems in 18 other states. As of June 2024 the official portal for account management is https://www.ezpassmd.com and general MDTA corporate contact is at 2310 Broening Highway, Baltimore, MD 21224.

This guide focuses on practical steps, exact contact points and timelines you will use when you call, mail or use the online portal. It explains how to open or close accounts, replace or move transponders, set up replenishment, dispute tolls and obtain refunds — the transactions most customers contact customer service about. Always verify any fee amount or schedule change on the official website or by phone before you act.

Primary contact points and hours

Most routine tasks can be completed online 24/7 at https://www.ezpassmd.com. For live assistance, the MDTA E‑ZPass Maryland customer service phone number (customer-service line) is 1-888-321-6824. MDTA’s main office phone is 410-537-5000 for corporate inquiries. Use the customer‑service line for account, billing and violation questions; it routes to specialists trained on tolling, payments and interstate interoperability.

Phone support hours vary by department; typical customer-service telephone hours are weekday business hours (approximately 8:30 AM–5:00 PM ET). Online chat and the account portal handle balance checks, statements and many updates outside those hours. If you need to visit in person, check the website for walk‑in locations and hours because physical office service windows and addresses can change seasonally.

How to open, update or close an account

Opening an account: create an account online at ezpassmd.com. You will need: full name, mailing address, primary email, one or more vehicle license plate numbers, vehicle make/model/year, and a valid payment method (credit/debit card or bank account for ACH). The online enrollment wizard typically shows any initial prepay requirement and estimated transponder shipping times; have a clear photo of the vehicle registration if the system requests verification. For fleet or commercial accounts, select the business/fleet enrollment option and prepare IRS or business paperwork.

Updating or closing: to change plates, add vehicles, or change payment methods, log into the account and use the “Manage Vehicles” or “Account Settings” screens. To close an account and request a refund, submit the closure request online or by phone; MDTA typically issues refund checks or electronic refunds within several weeks after final reconciliation. Keep records of confirmation numbers and expect the account closure to trigger a final statement showing unused balance and any outstanding violations.

Transponders, installation and replacement

E‑ZPass Maryland supports several transponder types (hard‑case portable tags and sticker-style tags depending on vehicle class). When you enroll you select the tag type appropriate for your vehicle; portable tags are convenient for moving between vehicles while sticker tags are permanently affixed. The online portal will display the expected shipping method and tracking number when the tag ships.

If a transponder is lost, damaged or not working, report it immediately via the online portal or by calling 1-888-321-6824 to deactivate the old tag and order a replacement. Expect replacement fees to vary; the portal shows current replacement costs before you confirm an order. If incorrect reads occur (toll charges that don’t match tag location), save photos of the tag/installation and your vehicle and submit them with the dispute form — customer service will audit toll reads using lane camera records and transponder read logs.

Payments, replenishment and refunds

Payment methods accepted include major credit and debit cards and ACH bank transfers for automatic replenishment. You can set a low‑balance threshold (commonly used thresholds are $10–$25) that triggers automatic replenishment. For predictable cash flow, enroll in auto-replenish and link a backup payment method; this prevents account suspension and reduces the risk of violation notices for unpaid tolls.

Refunds are issued after account closure or when an advertised credit is due after an audit. Typical turnaround for a mailed refund is 2–6 weeks; electronic refunds tied to the original payment method (when available) are often faster. Always request a written confirmation number and expect a final account reconciliation showing exact tolls, fees and the refunded amount.

Violations, disputes and escalation

Violations occur when a toll is unpaid or your transponder didn’t read. If you receive a violation notice, it will include a violation number, date/time/location of the incident and the toll assessed. Common first steps: log into your account, verify the corresponding vehicle and plate, then check transaction history for the toll event. If the toll appears in your account, it may be a processing lag — allow 48–72 hours for online transactions.

• To dispute: gather your account number, violation number, vehicle registration, photos and any supporting evidence. Submit an electronic dispute through ezpassmd.com or mail the documentation to the address on the violation notice. Typical investigative response times are 30–60 days.
• Escalation: if you disagree with the initial determination, follow the appeal instructions on the violation notice; appeals often require notarized affidavits or in‑person hearings for more complex cases.

Tips for frequent users, businesses and interoperability

If you commute across state lines, verify that your E‑ZPass Maryland transponder is compatible with the lanes you use; E‑ZPass is interoperable across 18 states but special facilities (express lanes or HOT lanes) may require specific transponder programming or an account grant. For business or fleet accounts, use dedicated fleet portals or account numbers to consolidate reporting; MDTA offers specialized billing and CSV export options for monthly reconciliation.

Document best practices: maintain at least one month of transaction statements, schedule quarterly account audits to reconcile plates versus transponders, and store confirmation numbers for every service call or online change. When in doubt about fees, schedules or enforcement procedures, call 1-888-321-6824 or verify the latest policies at https://www.ezpassmd.com to avoid surprises.
