Diamond Cab
Book a ride

Seattle · 24 hours a day

The fare you are quoted is the fare you pay.

Diamond Cab publishes flat rates across Seattle. Not an estimate that moves with traffic, and never a surge multiplier. You see the price before you confirm, and that is the price on your receipt.

How it works

Five steps, and no surprises at the end.

Book on the website or in the app. Either way the fare is settled before a driver is on the way, and you can watch the cab approach once one accepts.

  2. Now or later

    Ride right away, or schedule it for a set time.

  3. Pick your cab

    Standard, XL, or wheelchair accessible.

  4. See the fare

    Your flat fare appears before you confirm anything.

  5. Confirm and track

    Watch your cab approach, with the driver and cab number.

Accessibility

Wheelchair-accessible vans are part of the core fleet.

Accessible transport is a ride type in our system, matched to the riders who need it, not a special request handled off to one side. Vehicles carry a ramp or lift and secure restraints, and drivers are trained in boarding assistance.
