It is managed by the Washington Metropolitan Area Transit Authority (WMATA) and is operated by various companies that contract to provide the service.

The service provides daily trips throughout the Transit Zone in the Washington Metropolitan region.

Customers are required to pay the fare to the driver in cash prior to boarding the vehicle or by using Metro's EZ-Pay Program, the trip origin and destination must be within 3/4 mile of fixed-route service (a bus stop or rail station).

Eligibility for paratransit service is defined in the ADA as being based on an individual's "inability to use public transit" due to a disability, and in some cases, this inability is a result of either accessible services not being offered at the desired time of travel or the absence of an accessible pathway to a nearby bus stop or rail station.

In November 2016, MetroAccess replaced its photo ID access card with a personalized SmarTrip card, allowing MetroAccess users to ride buses for free, and use the faregates on Metrorail to take rides at no charge instead of entering via the emergency gate.
