For you Illinois Tollway I-PASS holders...
How do I cancel my I-PASS account?
To cancel your account, you must return your I-PASS transponder. For your convenience, this may be done either in person or through the mail.
If a transponder has been painted, designed or tampered with, the deposit will be forfeited.
If a customer does not want to return their transponder(s), they need to notify the cutsomer service center. Their deposit will be forfeited.
If canceling your account through the mail:
Via certified mail, send your transponder, wrapped in foil, with a letter requesting the I-PASS account be closed that also includes your return address. Your balance and deposit will be refunded within 45 days of receipt of the transponder and request. If you opened your account with cash or check, a check will be mailed to the address indicated in the letter. If you opened your account with a credit or debit card, the card registered on the account will be credited.
Send transponder to:
I-PASS Fulfillment Center
P.O. Box 806518
Chicago, IL 60680
If canceling your account in person:
You can return your transponder to an
I-PASS Customer Service Center.
Upon receipt of the transponder, a customer service representative will be able to return your deposit and any remaining balance to your credit card.
You cannot close an account and return your transponder to a Jewel-Osco or a Road Ranger (I checked). It must be returned to a real Customer Service Center (Weekdays only, 7AM to 6PM). The Tollway's Central Administration Building at 2700 Ogden Avenue in Downers Grove, IL is the main one, but you can also return it Southland Chicago Lincoln Oasis, Belvidere Oasis (I-90), Lake Forest Oasis, and O'Hare Oasis.
Also where you can return the transponder are the Hinsdale Oasis, only open on Mondays 10AM - 3PM), and the Dekalb Oasis (I-88) is only open on Fridays 10AM - 2PM.
The Des Plaines Oasis (I-90) north of O'Hare does not have a Customer Service Center.
BTW, if you still have your I-PASS (or EZ-PASS) in your vehicle and aren't able to get it returned while having the BESTPASS installed, make sure you wrap the old transponder in aluminum foil (I place mine in the fridge, which is metal, when I don't want it used).
