GS25

GS25, then known as LG25, opened their first store in Dongdaemun-gu, Seoul, in 1990. However, in 2005, GS Group split from the LG Corporation, the name of LG25 was correspondingly changed to GS25. In March 2019, GS25 changed their brand identity for the first time since changing their name to GS25. With the new identity, a new slogan of "Lifestyle Platform" began to be applied to all new store signage. However, as of August 2019, most stores still use the former identity.

In the late 2010s and early 2020s, services such as delivery, apps, and membership were expanded.
