Currently, lists of Foursquare users checked in at any given location will show their surnames as initials - "John Smith" would appear as "John S.", for example.
However from January 28 the app will remove that privacy measure to publicly display users' full names next to all their check-ins.
When a user checks in using the app, their physical location is viewable by their Foursquare friends as well as by strangers who have checked in at the same location.
In its official announcement Foursquare said the change aimed to make the app less confusing, by ensuring all users' were listed in the same way.
"Currently, Foursquare sometimes shows your full name and sometimes shows your first name and last initial," the announcement read.
"In the original versions of Foursquare, these distinctions made sense. But we get emails every day saying that it's now confusing. So, with this change, full names are going to be public."
Foursquare reminded users they can alter their full name and control who sees their check-ins by changing their account settings.
Last month Facebook announced it was scrapping users' ability to hide their name from search results to prevent strangers from looking them up, part of a raft of new privacy settings introduced by the network.
