Who Are ATEEZ? Members, ATINY and the Album Series

This guide answers the question “who are ATEEZ” from the beginning, for a reader who knows none of the vocabulary that usually comes with it. By the end you will know the eight member names and the source that lists them in that order, what the group’s name is short for and what ATINY means. It also sets out where the album series starts and how it runs to 2026, how many times a release has reached number one on the United States album chart and which channel the group itself uses to post schedule notices.

Each step below names one thing to look up and the dated source that states it. The guide was checked on 27 August 2026 against those sources: press reports dated between 1 January 2023 and 6 July 2026, and the group’s official YouTube channel as it stood that day. Nothing here asks you to do anything with the information.

1. Read the eight member names in the order KQ Entertainment’s renewal statement gives them

On 10 July 2025, KQ Entertainment said it had completed contract renewals with all eight members for a further seven years, Soompi reported. An agency is the company that manages a group and releases its music. The agency’s own statement, carried in Korean by iMBC, names the eight in this order: 홍중 (Hongjoong), 성화 (Seonghwa), 윤호 (Yunho), 여상 (Yeosang), 산 (San), 민기 (Mingi), 우영 (Wooyoung), 종호 (Jongho). Korea JoongAng Daily lists the same eight names.

This is the sequence the agency used in its statement, and nothing more than that. The agency said it was pleased to continue the relationship on the trust built over the previous seven years. It added that it would not hold back on supporting each member to express their potential and move on to bigger stages.

2. Look up what the name ATEEZ stands for

Korea JoongAng Daily states that the group’s name stands for “A TEEnager Z”, and explains it as a group of teenagers who can do everything from A to Z. That is the whole of the sourced explanation: the letters A and Z stand for the two ends of the alphabet, and the name places the group between them.

3. Look up what ATINY means

ATINY is the fandom name — the official name a K-pop group gives to its listeners as a group, so that press and the group itself have one word for them. Korea JoongAng Daily states that ATEEZ’s fandom is called ATINY, and that the word is a portmanteau, meaning two words fused into one: ATEEZ and Destiny.

4. Start the album series at TREASURE EP.1: All To Zero in October 2018

Korea JoongAng Daily writes that ATEEZ debuted in October 2018 with its first mini album, TREASURE EP.1: All To Zero, under KQ Entertainment. Soompi gives the same debut: October 2018 with TREASURE EP.1 : All To Zero.

EP is short for extended play, a release that carries fewer tracks than a full-length album; in the Korean industry the same short format is often called a mini album, and press reports use both words for the same numbered releases in this group’s catalogue. The numbering in the album titles — EP.1 and onward — belongs to the series the release sits in, and is separate from the running count of how many mini albums the group has put out in total.

5. Follow THE WORLD trilogy to its end in December 2023

THE WORLD is the album series that follows the TREASURE releases, and it runs in three parts:

• THE WORLD EP.1 : MOVEMENT, released in 2022, reached number three on the Billboard 200, according to Korea JoongAng Daily. The Billboard 200 is the weekly United States album chart published by Billboard magazine, and it ranks the best-performing albums in that country.
• THE WORLD EP.2 : OUTLAW reached number two on that chart in July 2023, Korea Herald reported.
• THE WORLD EP.FIN : WILL reached number one on the Billboard 200, the group’s first chart-topper there, Korea Herald reported on 11 December 2023. The same report notes the album also reached number two on the United Kingdom’s Official Albums Chart, the weekly album ranking for that country.

The “FIN” in the third title marks the end of that series.

6. Track the GOLDEN HOUR series from Part.1 in May 2024 to Part.5 in June 2026

Korea Herald writes that the GOLDEN HOUR series is built around the group’s brightest moments. Five parts have been released, each with its place in the running count of the group’s mini albums:

• GOLDEN HOUR : Part.1, the tenth mini album, released on 31 May 2024, Korea Herald reported. The same paper reported that the group teased the album during its Coachella set on 19 April 2024, with the title “Golden Hour” printed on the folding fans used on stage, and that ATEEZ was the first K-pop boy group to perform at that festival.
• GOLDEN HOUR : Part.2, the eleventh mini album, which entered the Billboard 200 at number one on the chart for the week ending 21 November 2024, Korea Herald reported.
• GOLDEN HOUR : Part.3, the twelfth mini album, released on 13 June 2025, Korea Herald reported.
• GOLDEN HOUR : Part.4, the thirteenth mini album, carrying five tracks and released on 6 February 2026, Sports Kyunghyang reported. Its title track is “Adrenaline”, which the paper describes as an intense EDM sound, and it was the group’s first release after the July 2025 contract renewal. A title track is the lead song a group promotes from a release, the one that gets the music video and the stage performances.
• GOLDEN HOUR : Part.5, the fourteenth mini album, released on 26 June 2026 through KQ Entertainment, Korea Herald reported. Its title track “Bad” is described there as a Brazilian funk-inspired dance track with an addictive chorus and a groove-driven beat, and Hongjoong and Mingi are credited with writing lyrics on every track of the album.

7. Count the Billboard 200 number ones: three as of July 2026

As of July 2026 there are three ATEEZ releases that have reached number one on the Billboard 200:

• THE WORLD EP.FIN : WILL, reported by Korea Herald on 11 December 2023 as the group’s first chart-topper there.
• GOLDEN HOUR : Part.2, which entered at number one on the chart for the week ending 21 November 2024, Korea Herald reported, noting it was the second time the group had reached that position.
• GOLDEN HOUR : Part.5, which entered at number one on the chart dated 5 July 2026 and was reported by Star News as the group’s third number one there; the figures behind that entry are covered in a separate article on this site.

A release can chart high without reaching number one, so the count of number ones is smaller than the count of charting albums: THE WORLD EP.1 : MOVEMENT reached number three and THE WORLD EP.2 : OUTLAW reached number two, and neither is part of the three above.

8. Check the group’s own channels when a date changes

Release dates and schedules move, and the sources above are dated press reports rather than live listings. The group’s official YouTube channel, @ateezofficial, is where the group posts its own videos and schedule notices, and KQ Entertainment’s channel, @kqent, is where the official music videos are posted. If a date in this guide no longer matches what you see elsewhere, those two channels are the official places the group and its agency publish to — not a fan account, a fan cafe or a community thread, none of which speak for the agency.
