What is the name of the Instagram feature that allows users to add a location tag to a Story?

The Instagram Story feature for adding a location tag is the Location sticker.

To use it, a creator opens the Story camera, taps the sticker button, and selects a place from Instagram’s location search. The sticker can then be positioned and styled on a photo or video. It is different from simply adding typed text that names a place: the sticker is an interactive location label connected to Instagram’s location system.

Instagram introduced contextual stickers for details such as location, time, and weather in December 2016, expanding the editing tools available in Stories. Location stickers also became part of location-based discovery, allowing public Story content associated with a place to be surfaced in location-related features.

A common mix-up is “geosticker,” a term more strongly associated with Snapchat and sometimes used informally for Instagram’s location effects. Instagram’s standard name for the Story control is Location sticker. Tapping one may open a location page or map view, although the exact display can change with app updates and privacy settings.
