Get to know the NCT members: Everything to know about NCT 127
NCT still runs on the same ambitious idea of unlimited members that first caught fans off guard. The group keeps its subunits focused on different regions while letting the overall roster grow and shift. NCT 127 now works as a seven-member unit after several lineup changes since the original ten-member era.
The concept keeps every member technically part of NCT U while subunits handle specific markets. That approach has let the company add new acts without breaking the original structure, and it still gives listeners plenty of distinct personalities to follow.
NCT 127 debuted on July 7, 2016, taking its name from the longitude of Seoul. The unit added Johnny and Doyoung in 2017, and the core identity has stayed steady even as the roster evolved.
NCT 127 Lineup Evolution Since 2020
The group has moved from ten members to a current active lineup of seven. Taeil left in August 2024 after allegations. Mark concluded his contract on April 8, 2026 and stepped away from all NCT activities. Winwin shifted focus to long-term projects in China, leaving him listed among former NCT 127 members in updated profiles. These shifts have shaped how the remaining members handle schedules and creative direction.
Recent and Upcoming NCT 127 Activities
The unit released the album Fact Check in 2023 and followed with the Neo City – The Momentum world tour in 2025, though military service thinned the lineup for several legs. SM Entertainment has mapped out a new album and supporting tour for the third quarter of 2026 to mark the group’s tenth anniversary. Planning continues around the seven active members who remain available for full promotions.
Military Service Updates
Taeyong enlisted in the Navy in April 2024 and finished service on December 14, 2025. Jaehyun completed his own service term and returned in May 2026. These absences forced the group to adjust choreography and recording plans, yet the members kept momentum through subunit work and pre-recorded content while waiting for returns.
NCT's Expanding Subunit Structure
The original four-subunit model has grown. NCT Wish and NCT JNJM have joined the roster, bringing the overall membership to around twenty-four. The additions keep the regional strategy intact while giving newer trainees their own platforms. Existing subunits continue to operate with adjusted lineups after the departures noted above.
Taeyong’s given name is Lee Tae-yong. He’s a South Korean singer, rapper, dancer, and songwriter who leads NCT 127. Before joining SM Entertainment he wanted to be a firefighter. The other members still joke that they cannot picture him in any other role. Taeyong has said he hopes to stay onstage for at least another decade. He washes his hands often because of mysophobia, though he calls the habit manageable. He has admitted that time away from his family remains the hardest part of the job. He completed Navy service in December 2025 and is now back with the active lineup.
Taeil is no longer a member of NCT 127. He was removed on August 28, 2024 following allegations and does not appear in current group activities or profiles.
Yuta’s given name is Nakamoto Yuta. He remains one of the two Japanese members in the unit. He sings, raps, dances, and still enjoys football. Yuta grew up in Osaka, played soccer for seven years, and keeps a dog named Rapunzel. He has said he wants to spend retirement time in Okinawa.
Jaehyun’s official name is Jeong Yun-o, though he was born Jeong Jae-hyun. He sings, writes songs, raps, acts, and serves as lead vocalist and dancer. His pale complexion earned him the nickname Casper. He lived in Connecticut for four years and speaks fluent English. He joined SM Entertainment in eighth grade, likes Pokémon, horror films, and musicals, and finished military service in May 2026.
Jungwoo was born in Sanbon and later moved to Gimpo. He enjoys cleaning and stays tidy, which fits well with Taeyong’s habits. He gets nervous easily yet excels at impressions. He always carries snacks and shares them during practice. He still cites Taemin from SHINee as the senior artist he respects most.
Johnny was born in Chicago as John Suh. He raps, dances, plays piano, DJs, and keeps the mood light. SM Entertainment scouted him at a global audition in Chicago in 2007. He switches between Korean and English with ease, though friends note his tone changes with each language. He remains an only child, loves cute things, and drinks plenty of coffee. His favorite films include Begin Again, Tangled, and The Pursuit of Happiness.
Doyoung was born Kim Dong-young in Guri. He serves as one of the main vocalists for both NCT U and NCT 127. He plays flute and performs trot songs. SM Entertainment cast him in 2013. He won first place at the Gyeongju Youth Arts Festival that same year and once played in a school band called Heart Attack. Members voted him most reliable during NCT Night Night broadcasts.
Mark’s contract with SM Entertainment ended on April 8, 2026. He is no longer part of NCT 127, NCT Dream, or any NCT subunit.
Haechan’s given name is Lee Dong-hyuck. He grew up between Seoul and Jeju Island. He has played piano since age five and keeps a mischievous streak. He listens to Michael Jackson and still hopes to write and produce his own songs.
Winwin stays primarily active with WayV and China-based projects. He is listed as a former NCT 127 member in updated profiles and does not appear in current unit schedules.
