Cash, Tokens, Transfers & Zone Charges
When riding on a City or Suburban Transit service, exact fare must be used.
Cash
The base cash fare for bus, trackless trolley, subway, and trolley service is $2.00. Cash is accepted for travel on all services. Exact fare must be used.
Regional Rail fares are based on zones. Knowing the zone of the station you are boarding and traveling to will help you determine the correct fare.
The base cash fare for Paratransit and Shared Ride service is $4.00.
Tokens
Tokens provide a discount off our base cash fare and cost $1.55 each.
Tokens may only be purchased in packs of 2 of two or more. Two cost $3.10; five are $7.75, and a ten pack costs $15.50. They are also available for bulk purchase.
Tokens may not be returned at any time for a refund.
Purchase anytime at shop.SEPTA.org
Transfers
A transfer may be purchased for an additional $1.00 when a trip requires more than one transit service in the same direction of travel. A re-transfer may also be purchased for an additional $1.00. The purchase of a transfer must occur when a customer boards the first service used; a re-transfer is purchased on the second service.
Transfers are sold on a bus, trolley, trackless trolley or Norristown High Speed Line onboard; and from a cashier booth attendant on the Market-Frankford Line and Broad Street Line.
