You can also mail expired transponders to the Illinois Tollway to be replaced. The mailed transponder will become active and ready to use in Illinois within 24 hours and in other states that accept IPASS within 48 hours. Your transponder should be wrapped in foil and sent by certified mail with a copy the replacement program letter that you received from Illinois Tollway, to I-PASS Fulfillment Center. P.O. Chicago, IL 60680. After receiving your old transponder, they will ship you a new transponder.
An iPass transponder has a life expectancy of around 10 years.
However, if you are an existing user on, you don’t have to wait to use your new transponder. You can activate the IPass online and use the transponder immediately, but just activating it on the IPass activate page. You can view my step by step guide on how to do that on my activate IPass transponder post.

To calculate your unpaid taxes to predict your charges, open the Trip Calculator and right-click on the map to see where your trip began (within Illinois), and where it ends (within Illinois). The calculator will then chart your route and identify your tax.

IPass Pay By Plate

Customers without an IPASS Account or EZPass transponder can pay unpaid tolls through the Pay By Plate system. Do know that using an E-ZPass or I-PASS transponder is still the cheaper way to pay tolls. Pay By Plate, however, is built on the I-PASS payment system and it allows you to choose from a variety of payment options and avoids costly fines and fees.  How the Pay By Plate system works is that when a vehicle goes through an Illinois tollway and does not have a transponder registered to that vehicle’s license plate, a picture is taken of that vehicle’s license plate and a toll fee is added to that license plate owner’s debt. 

What are the options for Pay by Plate?

  • You can enter your vehicle information and payment information in the Pay By Plate unpaid tolls system for up to 14 days to pay for an unpaid toll. This will ensure that you don’t pay any additional fees or fines. TIP: If you have already traveled, make sure that your plate information is up-to-date to reflect your travel date.
  • Pay by Plate is a great option if you are in a rented or borrowed vehicle but do not have or want an E-ZPass or I-PASS transponder. You can simply enter your plate, payment, and travel dates within 14 days from the date of your first travel. Paying this one toll would be cheaper than buying an IPass transponder for $30.
  • Managing multiple vehicles? Pay By Plate allows you to do this too. I-PASS is the best way to manage your vehicles. However, you can also add multiple vehicles and manage payment methods through the Pay By Plate system. You can also add an I-PASS transponder to a pay by plate account.
