On September 17, 2026, EDAM’s official Instagram @edam.official posted “HAPPY IU 18th Anniversary☁️💜” to celebrate IU’s 18th debut anniversary.
The post used tags including #아이유, #IU and #IU_18th_Anniversary as part of EDAM’s official anniversary greeting.
EDAM’s official X account shared the same anniversary theme. IU NOW combines the two official sources to avoid publishing the same event twice.
