Pay your Illinois tollway bill through the Illinois Tollway's official website or by mail

The Illinois Tollway operates I-Pass, the electronic toll collection system used on tollways in the Chicago area and across Illinois. If you have an I-Pass account, you can pay your bill online through the I-Pass customer service portal at www.illinoistollway.com. You'll need your account number and the payment method on file — typically a credit card, debit card, or bank account.

If you don't have an I-Pass account but received a toll bill in the mail, you can pay that specific bill online using the bill number printed on the notice. The tollway also accepts payment by phone at 1-800-UC-IPASS (1-800-824-7277) or by mail if you prefer not to use the website.

Key Takeaways

  • I-Pass accounts can be managed and paid online at www.illinoistollway.com using your account number and a credit or debit card.
  • If you received a toll bill in the mail, you can pay it online using the bill number without creating an account.
  • The Illinois Tollway accepts payment by phone, mail, or in person at customer service centers if online payment is not an option for you.
  • Setting up automatic replenishment on your I-Pass account prevents your balance from dropping too low and triggering violation notices.

Logging into your I-Pass account online

To access your I-Pass account on the Illinois Tollway website, click "Sign In" on the homepage and enter your username and password. If you don't have a username yet, you'll need to create an account first by providing your I-Pass account number, email address, and a password. Your account number appears on your I-Pass transponder or on any toll bill you've received.

Once you're logged in, you can view your current balance, recent transactions, and any outstanding charges. The account dashboard also shows you when your balance is running low and lets you set up automatic replenishment so tolls are paid before your account empties.

Making a one-time payment online

From your I-Pass account dashboard, select "Make a Payment" or "Pay Now." You'll be asked to enter the amount you want to pay and choose your payment method. The Illinois Tollway accepts Visa, Mastercard, American Express, and Discover cards, as well as electronic bank transfers (ACH) from a checking or savings account.

After you submit your payment, you'll receive a confirmation number on screen and via email. Most online payments process when ready, though bank transfers may take one to two business days to appear in your account. Keep your confirmation number for your records.

Setting up automatic payments

Automatic replenishment is the easiest way to keep your I-Pass account active without thinking about it. From your account settings, select "Manage Auto Replenishment" and choose a target balance — for example, you can set it to automatically add $25 when your balance drops below $10. You'll specify which payment method to use and confirm the setup.

Once automatic replenishment is active, the Illinois Tollway will charge your card or bank account whenever your balance falls below your chosen threshold. You can change or turn off automatic replenishment at any time through your account settings. This prevents your account from going negative and triggering violation notices.

Paying a toll bill received by mail

If you received a bill in the mail for tolls you didn't pay with an active I-Pass account, you can pay it online without logging into an account. Go to www.illinoistollway.com and look for "Pay a Bill" or "Pay Toll Violation." Enter the bill number from your notice and the amount due, then select your payment method.

The bill number is printed at the top of your toll notice. If you can't locate it, you can also call 1-800-UC-IPASS to look up your bill by license plate number. Paying online is faster than mailing a check, and you'll receive a receipt when ready.

Other ways to pay if you can't use the website

If you prefer not to pay online, the Illinois Tollway offers several alternatives. You can call 1-800-UC-IPASS (1-800-824-7277) to pay by phone using a credit card or bank account. Customer service representatives are available Monday through Friday, 7 a.m. to 7 p.m. Central Time, and Saturday 9 a.m. to 5 p.m.

You can also mail a check or money order to the Illinois Tollway at the address printed on your bill. Include your account number or bill number with your payment so it's credited correctly. Payment by mail typically takes 7 to 10 business days to process. Some Illinois Tollway customer service centers also accept in-person payments, though locations and hours vary — call ahead to confirm.

Frequently Asked Questions

What if I don't have an I-Pass account but drive on Illinois tollways?

If you drive on tollways without an I-Pass transponder, the tollway photographs your license plate and sends you a bill by mail. You can pay that bill online using the bill number, or you can open an I-Pass account to avoid future bills. Opening an account and getting a transponder lets you pay tolls electronically at a discounted rate.

How long does it take for an online payment to show up in my account?

Credit and debit card payments usually appear in your I-Pass account within minutes. Bank account transfers (ACH) typically take one to two business days. You'll receive a confirmation email with your transaction details either way, so you can track the payment if it doesn't show when ready.

Can I pay someone else's I-Pass bill online?

You can pay a toll bill received by mail using the bill number, even if it's not your account. However, to access and pay an I-Pass account directly, you'll need the account holder's username and password. If you need to manage someone else's account regularly, ask them to add you as an authorized user through their account settings.

What happens if my online payment fails?

If your payment is declined, you'll see an error message on the website explaining why — usually an expired card, insufficient funds, or a mismatch in your billing address. Try again with a different payment method, or call 1-800-UC-IPASS to troubleshoot. If your account balance goes negative, you'll receive a violation notice by mail.

Is it safe to pay my I-Pass bill online?

The Illinois Tollway website uses encryption to protect your payment information. Never share your account username or password with anyone, and only enter your payment details on the official Illinois Tollway website — not through links in emails or texts, which may be fraudulent.
