Refer-A-Friend Promotion

Refer-A-Friend: $10 for You, $10 for Them

Are you a South Bay Expressway FasTrak customer? You could earn $10 in toll credits for every new account opened with your referral code. Click here to login to your FasTrak account to view your referral code.

Send an email, call, or Facebook your friends and family to take advantage of the Refer-A-Friend offer. Refer as many friends as you like and get $10 in toll credits for every account opened with your referral code!

When your friend opens a new FasTrak account and uses your referral code, they will receive $10 in toll credits to use on South Bay Expressway. After your friend’s account is open for 90 days, you’ll receive a $10 toll credit too.

New customers can receive an extra $5.01 in free toll credits by combining the Refer-A-Friend offer with a FasTrak transponder purchased at Costco for $34.99.

Important Information about our Customer Service Center

In observance of Labor Day, the Customer Service Center will be closed on Monday, September 7, 2015. We will resume normal business hours on our next business day.

Also note there will be no Toll Attendants on duty at the Otay Mesa Toll Plaza on Labor Day. Cash-paying travelers should plan accordingly as Automated Cash Machines take exact change only. Payment may also be made by credit card at the machines. We apologize for any inconvenience.


In July, the Interactive Voice Response (IVR) and telephone prompts changed. Please listen and choose carefully when you call the Customer Service Center.
