The main EZPassMD customer service number is 1-888-321-6388

This is the primary phone line for EZPassMD account holders in Maryland. The number works for questions about your transponder, toll charges, account balance, and payment methods. Call this number during business hours — typically Monday through Friday, 8 a.m. to 5 p.m. Eastern time — to speak with a representative or navigate their automated system.

If you are calling from outside Maryland or from an international number, you can also reach EZPassMD at their main office line. The automated system will route you to the right department based on your account type and the reason for your call.

Key Takeaways

  • The main EZPassMD customer service number is 1-888-321-6388, available Monday through Friday during business hours.
  • You can also contact EZPassMD through their website at www.ezpassmd.com, which has a contact form and live chat during operating hours.
  • Have your transponder number or license plate ready when you call, as representatives will need it to look up your account.
  • If you need to report a lost or stolen transponder, you can do this by phone or through your online account portal.

What information to have ready before you call

When you contact EZPassMD, have your transponder number on hand — it is printed on the device itself and also appears on your monthly statement. If you do not have the transponder number, your license plate number works as a backup identifier. Representatives can pull up your account using either one.

If your call is about a specific toll charge or account issue, have your recent statement or the date of the transaction ready. This speeds up the process and helps the representative locate the exact charge you are asking about. If you are calling about a payment problem, know which payment method you used (credit card, bank account, or prepaid account).

Online contact options and hours

EZPassMD also offers contact through their website at www.ezpassmd.com. You can submit a contact form with your question, and a representative will respond within one to two business days. During business hours, the website often has a live chat option where you can type your question and get an when ready response without waiting on hold.

The live chat is typically available Monday through Friday, 8 a.m. to 5 p.m. Eastern time. If you contact them outside these hours, your message will be queued and answered the next business day. The website also has a searchable FAQ section that covers common questions about tolls, accounts, and transponders — you may find an answer without needing to call.

Handling common reasons for calling

If you are calling about a toll charge you do not recognize, have the date and location of the toll ready. EZPassMD can look up the specific transaction and explain what happened. Disputed charges can sometimes be reversed if there was an error, but the representative will need to investigate first.

If your transponder is not working or you are not receiving statements, tell the representative when you last used it and what problem you noticed. They may send you a replacement transponder by mail, which typically arrives within five to seven business days. If you need a transponder urgently, ask whether they have expedited shipping options.

If you are calling to add a vehicle to your account or change payment methods, the representative can often handle this over the phone. You will need the new vehicle's license plate number and the new payment information ready.

What to do if you cannot reach someone

If the phone line is busy or you are calling outside business hours, the automated system will offer to take a message or direct you to the website. Leaving a message is usually faster than waiting on hold, and a representative will call you back within one business day during the week.

If you have an urgent issue — such as a transponder that is not working and you need to cross a toll road when ready — explain this to the automated system. Some urgent requests are routed to a priority queue. If the automated system does not offer this option, hang up and call back; sometimes a live representative will pick up on the second attempt.

Mailing address and other contact methods

If you prefer to write instead of call, EZPassMD accepts mail at their office address. You can find the current mailing address on their website under "Contact Us." Mail typically takes one to two weeks to reach them and another week or two for a response, so this method is slower than calling or using the website contact form.

Some account changes — such as updating your address or adding a vehicle — can be done through your online account portal without calling at all. Log in to www.ezpassmd.com with your account number and password to see which changes you can make yourself. This is often faster than calling during busy times.

Frequently Asked Questions

Is there a fee to call EZPassMD customer service?

No. The 1-888-321-6388 number is toll-free. You will not be charged for the call, though standard phone plan rates may explore if you are using a cell phone with limited minutes.

Can I reach EZPassMD on weekends or holidays?

The phone line is not staffed on weekends or holidays. However, you can submit a contact form or message through their website at any time, and a representative will respond the next business day. The website FAQ and account portal are available 24/7.

What if I am calling from outside the United States?

The toll-free number may not work from outside the U.S. Use the contact form on www.ezpassmd.com instead, or call their main office line (which will be listed on the website). International calls may incur long-distance charges depending on your phone plan.

How long does it usually take to speak with someone?

Wait times vary depending on call volume. During peak hours (mid-morning and early afternoon on weekdays), you may wait 10 to 20 minutes. Early morning or late afternoon calls typically have shorter waits. Using the website contact form or live chat often has no wait at all.

What if my question is not answered by customer service?

Ask the representative to escalate your issue to a supervisor or specialist. Some questions — such as disputes over toll charges or account errors — may need to be reviewed by a different department. The representative can start this process and give you a reference number to track your case.
