NCT - 엔씨티

How Many Members Are In NCT? Let’s Find Out!

Who has never heard about NCT? It’s a really big group that was formed by Lee Soo-man, as the producer and the founder of SM Entertainment. NCT (엔시티), itself, stands for Neo Culture Technology. The name describes the group’s concept: that it will have an unlimited number of members. NCT consists of 21 members as of January 2019, and is divided into several subunits based on the concept, their ages, and their origins. The NCT sub-units consist of NCT U, NCT 127, NCT Dream, and the latest one is WayV.

Two years after SM introduced another three new members of NCT, in 2020, once again SM introduced another two new members that will join NCT. As we know the concept of NCT is having unlimited numbers of members, it is not a new thing anymore for the fans. The two new members were introduced to the public on September 20th, 2020, as they were preparing another new project that will combine all of the members for their second album, NCT 2020 Resonance Pt. 1 on October 12th, 2020, featuring all 4 units and the 2 new members, Shotaro and Sungchan, who are set to join a future NCT unit. So, right now NCT consists of 23 members as of October 2020.

Before their official debut, they were already known as part of SM Rookies, and everyone had been waiting and very much anticipating their debut as NCT. But from their debut until now, many people are still confused about their concept and their member distribution. So now, Channel-Korea will discuss the overall picture of NCT.

Stay tuned, and let’s get started!
