A geonotice is a notice on Special:Watchlist that is displayed only to users who are physically located in some subset of the Earth. The configuration page of geonotices is on Wikipedia:Geonotice/list.json. View the active geonotices and the regions they cover on Wikipedia:Geonotice/Map.
The purpose of geonotices is to announce events that would be of great interest to people in a specific region, but that would not be interesting to most of our readers. The use of targeted messages allows us to scale our communication better; rather than flooding people with multiple messages or avoiding messages entirely, we can display messages only to the people who are most likely to find them useful.
Example uses for targeted messages are: to announce upcoming Wikipedia meetups and local events, for local chapter activities and to advertise mailing lists focused on geographical areas.
Geonotices requested here are only displayed on the watchlist on the English Wikipedia. If you want to target users of all Wikimedia Foundation wikis in a particular geographical area, you can go to meta:CentralNotice to request a geotargeted banner.
No data or personal information is gathered from users to make this notice possible, nor does this notice share any user's personal information with outsiders.
