E‑ZPass Maryland — Comprehensive Customer Service Guide

Overview and who runs it

E‑ZPass Maryland is the electronic toll collection system managed by the Maryland Transportation Authority (MDTA). MDTA operates the toll facilities and the customer service program that supports transponder issuance, account maintenance, billing, and violations processing. The program has served commuters and commercial fleets since statewide interoperability began in the 1990s and currently supports millions of transponder accounts across the region.

This guide focuses on practical customer service procedures: how to contact MDTA/E‑ZPass Maryland, typical fees and timelines, the options available to resolve account or billing problems, and best practices for personal and business customers. Where precise numbers are cited, they are referenced to the program’s published resources and common operational practice as of 2025; always validate a specific fee or deadline via the official site before acting.

Primary contact channels, hours, and address

The central customer service hub for E‑ZPass Maryland is accessible by phone, web, and mail. The main telephone number most commonly published for customer assistance is 1‑888‑321‑6824; you can also find program details on the official portal at https://www.ezpassmd.com and on the MDTA site at https://mdta.maryland.gov. Online services (account login, payments, dispute submissions) are available 24/7; live agents have fixed business hours.

Typical in‑office business hours for MDTA customer service are Monday through Friday, roughly 8:30 AM–4:30 PM Eastern; these hours can vary by season or agency schedule. The MDTA administrative address commonly used for mailed correspondence and returned transponders is 2310 Broening Highway, Baltimore, MD 21224. For time‑sensitive issues (appeals, title holds, business account setup) use phone or the secure online portal for faster processing.

Opening accounts, transponder types, and fees

Individual and business accounts are both available. Personal accounts are often set up online in under 10 minutes with a valid driver’s license, a vehicle plate number, and a credit/debit card or bank account for replenishment. Business accounts allow multi‑vehicle management, consolidated invoicing, and delegated user access; expect additional documentation such as a federal EIN or Maryland business registration when applying.

Maryland issues sticker tags and portable/transponder devices. The common practice has been an initial transponder deposit (frequently $10) and a required minimum prepaid balance (commonly $25) to activate an account — amounts that have been posted historically on MDTA/E‑ZPass pages. Replacement transponders, account upgrades, and expedited shipping incur separate charges; verify current prices on the portal before ordering. If you need a specific model for a commercial vehicle or motorcycle, request it explicitly during setup to avoid incompatible toll reads.

Payments, replenishment methods, and receipts

E‑ZPass Maryland accepts automatic replenishment via credit/debit card and ACH (bank draft), plus one‑time online payments. Accepted cards typically include Visa, MasterCard, Discover, and American Express. Customers can configure automatic reload thresholds (for example, reload $25 when balance drops below $20) to prevent account-negative tolls; setting auto‑replenish is the fastest way to avoid violations caused by low balances.

Payment processing: online payments post to your account immediately; phone payments are usually processed the same business day if placed during business hours. Paper invoice payments (mailed checks) require extra lead time — mail processing may take 7–14 business days, so use electronic payment methods for urgent balance issues. The portal provides downloadable receipts and transaction history for accounting and expense reconciliation; businesses should download monthly reports (CSV/PDF) for fleet bookkeeping.

Unpaid tolls, violations, and dispute resolution

If a toll cannot be collected from an E‑ZPass account (for example, low balance or unread transponder), the MDTA issues an invoice or violation notice to the registered vehicle owner. Timeframes vary, but initial invoices commonly arrive within 30 days of the toll event. Unpaid invoices can escalate to civil penalties, additional administrative fees, and, for long‑outstanding accounts, vehicle registration holds imposed in coordination with the Maryland Motor Vehicle Administration (MVA).

Dispute procedures: you should gather date/time of travel, location (bridge or toll plaza), transponder serial number, and any supporting evidence (photo, proof of travel on a different device) and file the dispute through the online portal or by certified mail. Expect a documented response within 30–45 days; complex disputes (cross‑agency or inter‑state reads) can take longer. Always preserve receipts and communication logs — these are the primary evidence when contesting assessments or preventing escalation to collections.

• How to dispute: 1) Log into your account, 2) select the transaction and choose “Dispute,” 3) upload evidence (photos, toll receipts), 4) note the transponder serial and vehicle plate. Keep reference numbers for all submissions.
• Escalation timeline: initial invoice ~30 days, first late notice ~45–60 days, registration hold or collections after ~90+ days if unresolved (timelines approximate; verify current policy online).

Best practices, fleet management, and accessibility

Practical tips to minimize customer service interactions: keep at least a two‑trip buffer in your balance (e.g., $25 for daily commuters), register license plates for vehicles that sometimes travel without the transponder, and authorize multiple payment methods on file for redundancy. For fleets, use the business portal to assign tags to vehicle IDs, set per‑vehicle thresholds, and export reconciliation reports — this reduces audit time and lowers accidental toll charges.

MDTA offers customer accommodations for non‑English speakers and accessibility services for customers with disabilities; request these services when you call or through the online help center. For escalations beyond standard customer service — such as billing errors over $100, account freezes, or policy clarifications — ask for a supervisory review and obtain a case number for follow‑up. If you need legal or legislative assistance with a systemic problem, the MDTA has an Ombudsman or Executive Office contact accessible via the main MDTA website.
