A station code is a brief, standardised abbreviation, or alphanumeric code, used by railways to identify a railway station uniquely (within a country or region). Codes are mostly used internally but can be seen on railway traffic signs and on some timetables.
In most countries, station codes are purely alphabetic, usually compromising a few capital letters for ease of identification, in some countries one capital and one or some lowercase letters.
See main article: List of Amtrak station codes. Amtrak encodes a few stations in Canada which it serves.
See main article: List of MTR station codes.
A three-letter code system is in use in the MTR to identify stations. For example, Whampoa station of the MTR has the code of WHA.[1]

In Japan, alphabetic station codes are not used. Japanese railways use station numbering, a sign system which assigns station codes consisting of a few letters and numbers to train stations.

In South Korea, station codes are purely numeric, to reduce the problem of language and writing system barriers. For example, Seoul Metropolitan Subway's Singeumho station has the code of 538.[7]
See also: List of railway stations in Denmark. In Sweden and Denmark, railway stations are assigned a capital letter followed by a sequence of lowercase letters that represent the station's name. For example, Stockholm commuter rail's Stockholm City Station has the station code Sci.[8] In Sweden the code is in a few cases a single capital letter, such as M for Malmö Central Station.
See also: List of Deutsche Bahn station abbreviations. Deutsche Bahn in Germany uses an alphabetic station code system called the DS 100 code, for example, Luckenwalde station in Brandenburg has the station code BLD.[9]
Stations normally have a code of three capital letters, sometimes two letters. They are called "stedskoder" (location codes). Examples: OSL=Oslo Central Station, GAR=Oslo Airport Station, TND=Trondheim Central Station and BO=Bodø Station.[10]
