What a FasTrak one-time payment is and when you need it
A FasTrak one-time payment is a single charge you make to your FasTrak account to cover tolls without setting up automatic monthly billing. You pay once, the balance sits in your account, and tolls are deducted as you use the road. This is different from a subscription plan where money is drawn automatically each month.
You would use a one-time payment if you drive the toll roads occasionally, want to avoid automatic charges, or need to add funds before a specific trip. The payment stays in your account until it runs out — there is no expiration date on the balance itself, though FasTrak accounts can be closed if unused for a long period.
One-time payments work on all FasTrak toll roads in California: the Bay Area bridges, I-680 and I-880 in the East Bay, I-25 in San Diego, and the 91 Express Lanes in Orange County. The payment method and speed depend on whether you already have a FasTrak account.

How to make a one-time payment online
Go to the FasTrak website at www.bayareafastrak.org (for Bay Area) or the regional site for your toll road. Log into your account with your username and password. If you do not have an account, you will need to create one first, which takes about 10 minutes and requires your vehicle information and a valid payment method.
Once logged in, look for "Add Funds" or "Make a Payment" — the exact wording depends on which regional FasTrak site you are using. Enter the amount you want to add. Most regions require a minimum of $20 to $50 per transaction. Select your payment method: debit card, credit card, or bank account. Review the details and confirm the payment.
The charge will appear on your statement when ready, but the funds may take one to two business days to show in your FasTrak account. You will receive a confirmation email with a transaction number. If you are driving before the funds post, tolls will still be charged to your account — FasTrak allows a negative balance temporarily, though you will receive a notice to add funds.
Paying by phone or through the FasTrak customer service line
Call 1-888-FASTRAK (1-888-327-8725) to speak with a representative. Have your FasTrak account number ready, or your license plate number if you do not know your account number. The representative will confirm your account details and ask how much you want to add.
You can pay with a debit card, credit card, or bank account over the phone. The representative will walk you through the process and provide a confirmation number. Processing takes one to two business days, the same as online payments. Phone lines are open Monday through Friday, 6 a.m. to 10 p.m., and Saturday and Sunday, 8 a.m. to 8 p.m. Pacific Time.
This method is useful if you do not have internet access, prefer speaking to a person, or need to verify your account details before paying. There is no additional fee for paying by phone.
Paying at a retail location if you do not have an account
If you do not have a FasTrak account yet, you can open one and add funds at a retail location in one visit. Locations include AAA offices, Costco, and various grocery stores and gas stations throughout California. Search for "FasTrak retail locations" on the FasTrak website to find one near you.
Bring your vehicle registration and a valid ID. Tell the cashier you want to open a FasTrak account and make a one-time payment. They will take your vehicle information, assign you an account number on the spot, and process your payment. Funds are available when ready — you can use the toll roads the same day.
Retail payments are typically cash or debit card only; credit cards may not be accepted at all locations. Minimum payment amounts at retail are usually $20 to $50, depending on the location. You will receive a receipt with your new account number and instructions for managing your account online.
What happens after your payment posts
Once your payment is in your account, tolls are automatically deducted each time you use a FasTrak toll road. You do not need to do anything else — your transponder or license plate is linked to your account, and the system charges you as you drive.
You can check your balance and transaction history anytime by logging into your FasTrak account online. Most accounts show recent charges within 24 hours. When your balance gets low, you will receive an email or text reminder (if you have opted in), though you are not required to add funds when ready — FasTrak will let your balance go negative temporarily.
If your balance stays negative for more than 30 days, you may receive a bill in the mail. If you do not pay within 60 days, FasTrak may suspend your account or refer the debt to a collection agency. Adding funds before your balance goes negative avoids these complications.
Minimum amounts and payment limits
Minimum one-time payment amounts typically range from $20 to $50, depending on your region and payment method. Online and phone payments often have a $20 minimum, while retail locations may require $25 or $50. Check your regional FasTrak website for the exact minimum in your area.
There is usually no maximum limit on a single payment, though some payment methods (like certain bank accounts) may have their own caps. If you want to add a very large amount, call FasTrak customer service to confirm the payment will go through.
Some regions offer discounts for prepaying larger amounts — for example, adding $100 or more might give you a small percentage back in toll credits. These promotions change seasonally, so check the FasTrak website before making a large payment to see if a discount is currently running.
What to do if your payment does not post
If you made a payment and it does not appear in your account after two business days, log into your FasTrak account and check your transaction history. The payment should show as "pending" or "posted." If it shows as posted but the balance has not updated, wait another 24 hours — the balance and transaction history sometimes update at different times.
If the payment does not appear at all, check your bank or credit card statement to confirm the charge went through. If your bank shows the charge but FasTrak does not, contact FasTrak customer service at 1-888-FASTRAK with your transaction number or confirmation email. Have your account number and the payment amount ready.
If your bank did not charge you, the payment may have been declined. Common reasons include an expired card, incorrect billing address, or insufficient funds. Try adding the payment again with a different payment method, or call customer service to troubleshoot the issue.
Frequently Asked Questions
How long does a one-time payment stay in my account?
Your balance never expires as long as your account is active. However, FasTrak may close accounts that have no activity (no tolls charged and no payments made) for 18 months or longer. If your account is closed, you can reopen it and the remaining balance will still be there, but you will need to register again.
Can I get a refund if I add too much money?
Yes. Contact FasTrak customer service and request a refund of the excess balance. Refunds are processed to your original payment method and typically take five to seven business days. Some regions may charge a small refund fee, so ask about that when you call.
What if I lose my transponder after I add funds?
Your balance is tied to your account, not the transponder. If you lose your transponder, contact FasTrak to report it and request a replacement. Your balance will transfer to the new transponder automatically. There may be a replacement fee for the transponder itself, but your toll balance is safe.
Can I use a one-time payment on someone else's vehicle?
No. Each FasTrak account is registered to a specific vehicle or license plate. If you want to pay tolls for a different vehicle, you need a separate FasTrak account for that vehicle. You can have multiple accounts under your name, each with its own balance.
What if I drive a toll road before my payment posts?
FasTrak allows your account to go negative temporarily. Tolls will be charged even if you have no balance, and your account will show a negative amount. You will receive a notice to add funds, but there is no penalty or late fee as long as you add funds within 30 days.
