Can I use my Clipper card on all Sonoma County Transit routes?

Yes, Clipper is accepted on all Sonoma County Transit buses. Card readers are located at the front of each bus.

Why do I need to tag again at the end of my trip?

Sonoma County Transit fares are based on the number of zones through which you travel. When you ride Sonoma County Transit, Clipper deducts the maximum fare when you tag on and then refunds any difference when you tag off as you exit the bus. This means you must tag your card to the card reader upon boarding AND exiting the bus to ensure you're only charged for the distance you travel and that Clipper applies any appropriate discounted fares and transfers. Note that each bus only has one card reader, located at the front of the vehicle. Clipper customers will need to exit at the front of the bus to tag off.

How long is my transfer good?

In order to receive a transfer discount, your entire journey must be completed within the 180-minute transfer period. On Sonoma County Transit and Golden Gate Transit buses, the transfer period begins when you tag off. On Santa Rosa CityBus and VINE Route 25, the transfer period begins when you tag upon boarding.

Do I need to ask for a paper transfer?

Clipper keeps track of your rides and automatically grants you appropriate transfer discounts when transferring to another agency that accepts Clipper. If you are transferring to a transit service that does not accept Clipper, you should request a paper transfer.

If I have a 31-Day Pass on my Clipper card, do I need to tag my card every time?

Yes. Whether you are paying your fare with cash value or a 31-Day Pass, you must tag your card to a Clipper card reader every time you board and exit the bus.

If I add a new 31-Day Pass on my Clipper card before my current 31-Day Pass expires, when does the new 31-Day Pass become active?

It depends on how you add your pass. If you add a new 31-Day Pass in person while the previous pass is still active on your card, Clipper will simply extend the expiration date of your current pass by 31 days, with no gap in between. If you want a gap in between your old pass expiring and the new one becoming active, purchase your new pass only after the old one expires, and the new pass will be activated the first time you use it.

If you are signed up for Autoload or you order your pass online or by phone, Clipper will automatically load the new pass to your Clipper card the next time you tag your card after the original pass has expired. For example, if you have a 31-Day Pass that expires on May 12, the new pass will not become active until the first time the card is tagged AFTER May 12. If you do not tag your card again until May 21, the new pass will be activated with a start date of May 21 and an expiration date 31 days from the start date. This happens automatically, with no disruption in your ability to use Clipper.
