Bangkok does not have one complete public list of every taxi stand. The clearest official pickup points are managed airport queues, designated transport-hub areas and some signed street stands.
Suvarnabhumi Airport directs passengers to its public-taxi service and ticket system. Don Mueang Airport also publishes designated taxi-counter information. Follow the airport's current signs rather than accepting an unsolicited offer inside the terminal.

Major stations and bus terminals may provide a signed waiting or feeder area, while some Bangkok districts mark street stands for local traffic management. Look for an on-site sign or staff direction; the exact loading point can move during construction or traffic changes.

A map pin, a line of parked taxis or repeated pickups can show demand without proving that the place is a designated rank. At a hotel, mall or attraction, ask staff for the current pickup point. Before entering, check the vehicle and agree on the lawful fare method for the trip.
