The designated operator of the Rep. of Korea, Korea Post, wishes to inform Union member countries and their designated operators that a fire on 26 September 2025 at a major national server facility has disrupted the entire postal system. The damage from the fire is significant, and full recovery is not expected in the short term. Therefore, Korea Post is facing limitations in meeting quality of service standards for all items (letter post, parcel post and EMS). Owing to the inability to verify the status of items, CN 17 requests may not be possible until further notice. All Korea Post service and call centres are affected.
