Where to Go: Physical Service Centers and 24/7 Hubs
While digital tools handle most tasks, certain situations, like returning a deactivated transponder, require a physical visit. Delaware offers both a central administrative hub and several 24-hour service terminals at major toll plazas to keep you moving.
The Dover Customer Service Center
The administrative heart of the system sits at 22-24 West Loockerman Street, Dover, DE 19904. This facility handles high-level tasks, including commercial fleet management and complex hardware logistics.
Operating hours at the Dover center match the phone support schedule. Its central location in downtown Dover makes it accessible for residents across Kent County and beyond.
24/7 Toll Plaza Locations
Realizing an account is empty at midnight does not have to be a disaster. Three major plazas feature administrative offices that remain open 24 hours a day, 7 days a week for account info and assistance.
- Dover Toll Plaza: SR-1, 200 Plaza Drive, Dover, DE 19901 (Handles Smyrna and Denney’s Road ramp inquiries)
- Biddles Corner Toll Plaza: SR-1, 2111 Dupont Parkway, Middletown, DE 19709 (Handles Boyd’s Corner facility inquiries)
- Newark Toll Plaza: I-95, 1200 Whittaker Road, Newark, DE 19702
These locations assist with account inquiries and basic troubleshooting at any hour. This ensures travelers are never stranded without support.
E-ZPass On-The-Go and Retail Partners
For those who need a transponder immediately rather than waiting for the mail, several retail partners offer “On-The-Go” tags. These units come pre-loaded with a starting balance for instant use.
Key distribution points include:
- AAA Offices:
- Wilmington: One River Place
- Newark: 1201 Churchman’s Road
- Dover: 124 Greentree Drive
- DMV Hubs:
- Wilmington: Hessler Blvd.
- Delaware City: Mid County Drive
- Georgetown: South Bedford Street Ext.
- Delaware House Welcome Center: Located at 530 JFK Memorial Highway in Newark.
Mailing Addresses: Ensuring Correct Routing
Sending a payment or an appeal to the wrong box can cause significant delays. Delaware utilizes a specific sorting system in Dover to manage different types of correspondence through the Delaware Department of Transportation.
Recommended Mailing Pathways
| Purpose of Mail | Address |
| Account Support and Commercial Apps | PO Box 777, Dover, DE 19903-0777 |
| Violation Payments and Appeals | PO Box 697, Dover, DE 19903-0697 |
| General DelDOT Admin | PO Box 778, Dover, DE 19903 |
| Toll Plaza Specific Correspondence | PO Box 1043, Dover, DE 19903 |
When returning a transponder, it should be sent to the physical Loockerman Street address in Dover. To prevent the unit from being read by toll antennas during transit, use the original silver shielding bag or wrap it securely in aluminum foil.
New for 2026: The Toll-By-Plate Revolution
The Delaware Division of Motor Vehicles has significantly improved the experience for occasional travelers. Delaware now utilizes a consolidated monthly invoice for “Toll-By-Plate” users, replacing the old system of individual notices.
This means drivers receive one statement at the end of the month covering all transactions. The system also includes a 60-day grace period to pay the net toll before administrative fees apply.
The End of Cash Ramps
As of 2026, cash is no longer accepted at any exit ramps. Motorists without a transponder are automatically billed via the “Toll-By-Plate” system. However, cash remains a valid payment method at the primary mainline toll booths on SR-1 and I-95 for those who prefer traditional methods.
Saving Money: The 30/30 Rule and Discounts
Regular commuters can significantly reduce their travel costs by utilizing the Delaware Frequent User Plan. This plan rewards drivers who travel frequently on specific corridors.
By recording 30 or more qualifying trips on SR-1 or US-301 within a rolling 30-day period using a single transponder, users receive a 50% discount. Keep in mind that trips on SR-1 cannot be combined with US-301 trips to meet this requirement.
Commercial fleets also benefit from specialized incentives. Vehicles with three or more axles receive an automatic 15% discount on the SR-1 corridor. This encourages heavy traffic to utilize the primary highway infrastructure.
Security Alert: SMS Smishing Scam Mitigation
With the rise of digital services, E-ZPass Text Scams have become more common. These messages often claim there is an outstanding balance and provide a link to a fraudulent website.
The Delaware News Portal confirms that E-ZPass Delaware does not send text messages for toll collection unless a customer has specifically opted into a notification system.
For secure account management, users should always verify their balance through the Official MyDMV Portal or ezpassde.com. Utilizing a unique 4-digit security PIN is the best way to keep an account protected.
2026 Holiday Closures
The main Customer Service Center and live telephone lines follow the state’s legal holiday calendar. On the following dates in 2026, administrative support will be unavailable according to the State Office Closings schedule.

During these closures, the 24-hour automated phone system and the official website remain the primary tools for account management.
Maintaining Hardware Reliability
Most “non-read” errors at toll plazas result from improper transponder placement. Following the Official Installation Guide ensures that your device works every time you pass through a lane.
For optimal performance, mount the unit two inches below the top of the windshield. Place it either behind or to the right of the rearview mirror.
Vehicles with metallic windshield tints or heated glass may require an external transponder. The Dover Customer Service Center provides these specialized units upon request to ensure seamless travel.
Streamlining Your Delaware Transit
Navigating Delaware’s tolling system in 2026 is more straightforward than ever, thanks to modernized invoicing and 24/7 plaza support. By keeping an account replenished and hardware correctly mounted, most common issues can be avoided entirely.
If a complex problem does arise, dialing 1-888-397-2773 remains the fastest way to find a resolution. Safe travels!
