Value can be added to the ORCA card anywhere ORCA is sold. You can add between $5 and $300 on the card's E-purse or a monthly pass.
Used like cash to pay bus or train fares, the fare for your ride is subtracted from the E-purse so you pay as you go.
Buy a pass
There are monthly regional pass options for Community Transit, Everett Transit, King County Metro Transit, Kitsap Transit, Pierce Transit buses and Sound Transit buses and trains. Buy a pass that has the per-trip value of the trip you usually take. Passes are good for trips with fares up to the per-trip value of your pass. If the fare of any trip is more than your pass, you can pay the difference with your E-purse.
Passes are good for one calendar month
For example: A July pass is good July 1-31. If you buy the July monthly pass on July 13, the monthly pass is only good until July 31. The 14th of July is the last day to buy a July pass. You may buy an August pass beginning July 1, but the pass will be good starting August 1.
