SECRET NUMBER

SECRET NUMBER is a four-member South Korean girl group under VINE Entertainment, consisting of Dinda, Min C, Ebin, and Navi. The group originally debuted as a five-member act on May 19, 2020 with their first single album Who Dis?, after their initial debut plans were postponed due to the COVID-19 outbreak.

They first gained attention with releases such as "Who Dis?" and "Got That Boom", later expanding their lineup in 2021 with the addition of Zuu and Minji during the era of "Fire Saturday". The group continued their momentum with multiple releases including "Doomchita", "Tap", and "Doxa", as well as their Japanese debut "Like It Like It", followed by "Starlight" and "Love Bye", highlighting their growing versatility and international activities.

Over time, the group underwent several lineup changes. Denise departed in February 2022, while in 2025, Léa, Dita, Jinny, and Minji left the group, prompting a temporary hiatus. The group later reorganized with new members and returned with "New Number", followed by the digital single "Bitter Sweet", though Soodam also departed in December of that year.

On April 14, 2026, VINE Entertainment officially announced that Zuu had left the group following the expiration of her contract on April 8, finalizing SECRET NUMBER as a four-member group moving forward.
