Use public_transport=platform to identify the places where passengers board or alight from public transport of any type, including boarding facilities at airports, bus stations, ports, railway stations, as well as for ski lifts and at roadside bus stops, taxi ranks. This tag was introduced by tagging proposal Public Transport in 2011.
Historically, a variety of tags have been used, each for a different mode, including highway=bus_stop (for bus stops), railway=platform (for railway, tram and subway platforms), aeroway=gate (at airports), amenity=taxi etc. These original tags are still more commonly used and were not invalidated by the new tag, and should be kept in order to ensure compatibility with legacy software. Additionally, at least some prefer more specific tags rather than single tag supposed to cover objects as diverse as railway platforms, bus stops and airport infrastructure.
How to map
The platform can be mapped as a 
or 
. Nodes are used for locations where there is no physical infrastructure (for example a customary bus stop without infrastructure or with a pole), a way is used for a location where a linear area is allocated for people using public transport, and an area is used when a more expansive size is allocated or where different platforms adjoin, such as at in a railway station. When the platform is mapped as an area, the tag area=yes is not required (round linear platforms part of a single route do not exist).
Platforms can be grouped, together with other associated elements, in a public_transport=stop_area relation. This relation may include public_transport=stop_position (where the vehicle stops), benches, separate shelters and even station buildings.

| railway | platform | A train, tram, subway, or light rail platform | ‽ Important |
| highway | bus_stop | A bus, trolley_bus or share_taxi stop/platform | ‽ Important, on at most one of any public_transport=stop_position and public_transport=platform pair. Note though that highway=bus_stop is only specified for nodes, not for ways! |
| highway | platform | If there is a raised platform at a bus stop | ? Optional |
| highway | footway | May break some GPS routers, when used. Only use this tag in combination with a platform is mapped as a way which connects to another highway=*. | Care should be exercised |
| name | Individual name | The name of the station/stop. Platform numbers are given using ref=*. | ‽ Important, except with subsuming public_transport=stop_area |
| ref | Reference | The reference by which the platform is known. This tag is often used for numbers of platforms/platform edges in train stations or bus stations. Use a semicolon (;) to separate multiple references (e.g. platforms with two edges along a railway track and therefore a different number for each edge.
