Talk:Station numbering

Seoul Metro also has used station numbering at last since 1983
The assigned station numbers of Euljiro 1-ga station and Seoul National University station were 2 and 28 each, as seen in the photos from the linked articles. Since the numbering system is otherwise not mentioned, it is unknown whether the numbering system was actively used for navigation. D6283 (talk) 14:35, 14 May 2021 (UTC)

Found it, though it is still vague. According to Line 2 Construction magazine (p. 666 onward), the station numbering in Seoul Metro was implemented soon after the phase 2 of Line 2 opened in Dec 1982. D6283 (talk) 01:16, 29 May 2021 (UTC)
