  • Participating transit agencies

  • Downtown San Francisco Muni fare machines
  • BART ticket machines
  • Add Value Machines at San Francisco or Palo Alto Caltrain stations

Clipper also offers Autoload where your card is reloaded each month automatically. For more information, visit or call the Clipper Customer Service Bureau at 1-877-878-8883.

How does Clipper know what fare to deduct?
A customer who qualifies for one of the discount categories (youth, senior, disabled) must apply for the appropriate Clipper card. When they travel using cash, the onboard Card Interface Device recognizes the type of card and deducts the appropriate cash value.

I have a Youth Clipper card, what happens when I turn 19?
On your 19th birthday, your Youth Clipper card will automatically change to an Adult Clipper card. This means youth discounts will no longer be granted and adult fares will be required. Note: If you have a Youth Monthly Pass on your card, it will be cancelled. This will happen even if it is the beginning or middle of the month. If you have cash value on your card, the Clipper system will automatically start deducting adult fare.

If your card is set up for autoload and your 19th birthday is coming up, follow these steps: 1) Disable Autoload before the new pass is loaded. This will prevent a product from being loaded that you will not be able to fully use. 2) After your birthday has passed, set up Autoload to load an adult pass.

Do I need to tag my card every time I ride, even if I have a Monthly Pass?
Yes. Regardless of whether you use cash or a Monthly Pass, you must tag your card to a card reader every time you board. Your tag is your proof of payment.

I have a Local Pass, but need to take an Out of SF route. How do I pay the difference?
The Local Monthly Pass will provide a local fare credit. The additional fare required for the out of San Francisco routes will be paid with cash from the Clipper card. [Please see the question below regarding specifics with Route KX.] If you do not have enough cash value on your Clipper card to pay the difference for the upgrade, your pass will not be accepted and you will need to pay full cash fare for the ride.

Can I combine my Clipper card and another form of payment to pay for my ride?
When using Clipper, you must pay your entire fare with the pass and/or cash on your Clipper card. You cannot combine cash, tickets or tokens with a portion from your Clipper card.

Will the same fare credit privileges apply for VTA, AC Transit, Caltrain?

Can I use my card to pay the fare of someone traveling with me?
Clipper cards are for individual use. Each rider 5 years of age or older must have his/her own card. The Clipper cards also have a feature that stops you from tagging more than once on the same bus within a 5-minute time frame. This feature was built in to protect you from accidentally tagging and being charged twice.
