How iPass payment works on Illinois tollways
iPass is an electronic toll collection system used on Illinois tollways. When you drive through a toll plaza with an iPass transponder mounted on your vehicle, the toll is deducted automatically from your prepaid account. You do not stop at a booth — the system reads your transponder and charges you electronically.
The Illinois Tollway Authority operates the system and sends you a bill each month if your prepaid balance runs low. You can pay that bill online, by phone, by mail, or in person at a payment location. The method you choose depends on how quickly you need the payment processed and whether you prefer to set up automatic payments.
Understanding how to pay keeps your account active and prevents toll violations or service interruptions. If your balance drops below a certain threshold, your transponder may be flagged, and you could receive a violation notice for tolls you drove through without sufficient funds.

Paying online through your iPass account
The fastest and most direct way to pay is through the Illinois Tollway website. Go to illinoistollway.com and log into your iPass account using your account number and PIN. If you do not have an online account yet, you can create one by entering your account number and the last four digits of the phone number associated with your account.
Once logged in, you will see your current balance, recent toll transactions, and an option to add funds. Click the payment or "Add Funds" button and choose your payment amount. You can pay with a debit card, credit card, or bank account. The system will confirm your payment when ready, and the funds are usually available in your account within one business day.
Paying online also lets you review your toll history and check whether any violations have been recorded against your account. This is useful if you want to confirm that tolls were charged correctly or if you need documentation for your records.
Paying by phone
You can call the Illinois Tollway customer service line at 1-800-UC-IPASS (1-800-824-7277) to pay by phone. Have your account number and a debit card, credit card, or bank account information ready. A representative will process your payment over the phone and give you a confirmation number.
Phone payments are processed within one business day, the same as online payments. This method is useful if you prefer speaking to someone or if you have questions about your account balance or recent charges. Customer service is available during business hours, typically Monday through Friday.
Paying by mail
You can send a check or money order by mail to the address printed on your monthly bill statement. Write your account number on the check or money order so the payment is credited to the correct account. Mail payments take longer to process — allow at least 10 business days for your payment to arrive and post to your account.
Mailing a payment is slower than other methods and is not recommended if your balance is low or if you need the funds available quickly. However, it is an option if you do not have internet access or prefer not to use a card over the phone.
Setting up automatic payments
The most reliable way to keep your iPass account funded is to set up automatic payments. Log into your account at illinoistollway.com, go to your account settings, and select the automatic payment option. You can choose to have a fixed amount deducted from your bank account or credit card on a schedule you set — for example, every month or whenever your balance drops below a certain amount.
Automatic payments prevent your account from running out of funds and eliminate the need to remember to pay manually. They also help you avoid toll violation notices, which occur when you drive through a toll plaza without sufficient funds in your account. Once set up, automatic payments continue until you cancel them through your online account.
What happens if your balance runs low
If your iPass balance drops below the toll amount for the next plaza you pass through, your transponder will be flagged. The Illinois Tollway Authority will send you a violation notice in the mail, which includes the toll amount plus a violation fee. You will have a important date to pay the violation, which is usually 30 days from the date of the notice.
Paying the violation promptly prevents additional penalties and keeps your account in good standing. If you do not pay within the important date, the Tollway Authority may suspend your transponder or refer the debt to a collection agency. This is why maintaining a positive balance or setting up automatic payments is important.

Frequently Asked Questions
Can I pay my iPass bill at a gas station or convenience store?
No, iPass payments cannot be made at retail locations. You must pay through the Illinois Tollway website, by phone, by mail, or at an official Tollway payment location. Some Tollway plazas have payment kiosks, but the online and phone methods are more widely available.
What if I lost my iPass transponder and need to pay for tolls I already drove?
Contact the Illinois Tollway at 1-800-824-7277 to report your lost transponder and ask about your account balance. You can pay any outstanding tolls using the same methods as a regular payment. You will need to order a replacement transponder, which typically costs around $25 to $35.
Do I get a receipt when I pay online or by phone?
Yes. Online payments show a confirmation number when ready on your screen, and you can print or save it. Phone payments also provide a confirmation number during the call. Keep these for your records in case you need to dispute a charge or verify payment.
Can I pay someone else's iPass bill?
You can pay if you have the account number and access to the account. If the account is not in your name, you may need to contact the Tollway to arrange payment or ask the account holder to add you as an authorized user.
