How to Pay E-470 Tolls and Manage Your Account

E-470 is a toll road in the Denver metro area, and you can pay tolls by setting up an account, using a transponder, or paying by mail after you receive an invoice

E-470 is a 47-mile highway loop around the Denver and Boulder metro areas. If you drive it without a payment method in place, the road authority photographs your license plate and mails you an invoice weeks later. You have three ways to pay: set up a prepaid account online, get a transponder (a small device that sticks to your windshield and charges your account automatically), or wait for the invoice and pay by mail or phone.

The fastest and cheapest route is a prepaid account with a transponder, because you lock in a discount on every toll. Without a transponder, you pay the full toll rate when you get the invoice. Setting up an account takes about 10 minutes online, and a transponder arrives by mail in 5 to 7 business days.

Key Takeaways

• A prepaid E-470 account with a transponder gives you a discount on every toll and charges automatically when you drive.
• If you drive without a transponder, E-470 photographs your plate and mails you an invoice at the full toll rate, which costs more than the discounted rate.
• You can set up an account and order a transponder at e-470.com, or call 303-537-3470 to do it by phone.
• Transponders take 5 to 7 business days to arrive; if you need to drive E-470 before yours arrives, you can add your vehicle to your account and pay the invoice later.
• If you receive an invoice you did not expect, you can dispute it or set up an account within 30 days to avoid a late fee.

How to set up a prepaid account and order a transponder

Go to e-470.com and click "Create Account" or "Manage Account." You will need your email address, a password, and a valid payment method (credit card, debit card, or bank account). Enter your vehicle information: license plate number, state, vehicle type, and year. E-470 uses this to match tolls to your account.

Once your account is open, order a transponder. The transponder is free, but you must fund your account with at least $25 before you can use it. You can add money by credit card, debit card, or automatic bank transfer. Choose how much to prepay—many drivers add $50 to $100 to avoid running low. The transponder will arrive in 5 to 7 business days. When it arrives, stick it to the inside of your windshield (upper driver's side is standard) and activate it in your account.

If you need to drive E-470 before your transponder arrives, add your vehicle to your account anyway. E-470 will photograph your plate, match it to your account, and charge your prepaid balance instead of mailing an invoice. This works only if your account is already open and funded.

What happens if you drive without a transponder or account

E-470 has cameras at every toll point. If you drive without a transponder and your vehicle is not linked to a prepaid account, the camera photographs your license plate. E-470 looks up your plate in the state motor vehicle database, finds your address, and mails you an invoice 2 to 4 weeks later. The invoice includes the full toll rate (not the discounted rate), plus a $2.50 processing fee per toll.

You can pay the invoice by mail, phone, or online. The invoice will have a due date, usually 30 days from the date it was mailed. If you do not pay by that date, E-470 may add a late fee and report the debt to a collection agency. If you receive an invoice and want to avoid future invoices, you can set up an account within 30 days and link it to the plate on the invoice. E-470 will credit any overpayment to your new account.

Transponder discounts and how prepaid rates work

E-470 charges different rates depending on the time of day and how you pay. With a transponder, you get the lowest rate—typically 25 to 40 percent less than the invoice rate. The exact discount varies by toll point and time of day. Peak hours (roughly 6 a.m. to 10 a.m. and 3 p.m. to 7 p.m. on weekdays) have higher tolls than off-peak hours, but the transponder discount applies to both.

Your prepaid balance is charged each time you pass a toll point. You can check your balance and recent charges anytime in your online account. When your balance drops below $10, E-470 sends you an email reminder. You can set up automatic reloads so your account refunds itself when the balance falls below a certain amount—this way you never have to think about it.

Managing your account online and by phone

Log into your account at e-470.com to view your balance, add money, see your toll history, update your payment method, or add or remove vehicles. You can also download a statement for your records. If you lose your password, click "Forgot Password" on the login page and E-470 will send you a reset link by email.

If you prefer to handle things by phone, call E-470 Customer Service at 303-537-3470. They are open Monday through Friday, 7 a.m. to 6 p.m. Mountain Time, and Saturday 8 a.m. to 4 p.m. You can set up an account, add money, dispute a charge, or ask about your transponder status. Have your license plate number and email address ready.

What to do if you received an unexpected invoice or charge

If you received an invoice for a toll you do not remember taking, or if you think you were charged twice for one trip, contact E-470 within 30 days of the invoice date. Call 303-537-3470 or log into your account and use the "Dispute a Charge" form. You will need to describe what happened and provide the date, time, and toll point if you can. E-470 will review the camera footage and respond within 10 business days.

Common reasons for unexpected charges: driving a rental car (the rental company's plate is registered, not yours), a family member driving your car, or a transponder that fell off or was not activated. If you were charged for a trip you did not take, E-470 can refund the toll and the processing fee. If your transponder malfunctioned, they may replace it at no cost.

Transponder replacement and troubleshooting

If your transponder stops working, falls off, or is damaged, contact E-470 and request a replacement. Replacements are free and arrive in 5 to 7 business days. While you wait, your account will still work—E-470 will photograph your plate and charge your prepaid balance. You do not have to pay an invoice rate.

If you move to a different state or sell your vehicle, remove it from your account online or by phone. This prevents future tolls from being charged to your account. If you keep the transponder and move it to a new vehicle, update your vehicle information in your account so tolls are matched correctly.

Frequently Asked Questions

Can I use my E-470 transponder on other toll roads?

No. E-470 transponders work only on E-470. Other Colorado toll roads (I-25 Express Lanes, US 36 Express Lanes, and T-Rex) use different systems and require separate accounts or payment methods. If you use multiple toll roads, you will need separate accounts for each.

What if I do not have a credit card or bank account?

You can pay E-470 invoices by mail with a check or money order. Write your invoice number on the check and mail it to the address on the invoice. You can also pay by phone using a debit card. However, to set up a prepaid account online, you will need a valid payment method. Call 303-537-3470 to ask about other options.

How long does it take to get a refund if I overpaid?

If your prepaid account has a balance over $100, you can request a refund online or by phone. E-470 processes refunds within 5 to 10 business days and sends the money back to the payment method you used to fund the account. If you set up an account to pay off an invoice, any overpayment stays in your account as a credit for future tolls.

What happens if my transponder is stolen or lost?

Contact E-470 immediately at 303-537-3470 and report it. They will deactivate the old transponder so no one else can use it, and send you a replacement free of charge. In the meantime, your account will still work—tolls will be charged to your prepaid balance when your plate is photographed.

Can I get a refund if I paid an invoice but then set up a transponder account?

Yes. If you paid an invoice within 30 days of receiving it and then set up a prepaid account, contact E-470 and explain what happened. They can review your account and may credit the overpayment to your new account or issue a refund, depending on the timing and amount.
