COEX Event Venue Guide

Plan an event at COEX with its spaces, location, source-backed operating rules, and official contacts in view. Grand Ballroom capacities were checked against the current official table. Existing catering, telecom, parking-pass and filing rules rely on older official documents whose original links now redirect; reconfirm current terms.

We handle venue sourcing, event planning, and on-site operations together. zzzarit’s venue support is included in full event management. We do not accept inquiries for venue rental or booking alone. Contact the venue directly about rental fees and availability.

  • The exhibition-hall regulations prohibit food sales and require advance notice for tasting samples.
  • Hall D requires advance notice of the food-providing entity for parties or mixed events.
04

Setup & teardown

Advance submission

Exhibition halls require a technical-support request, floor plan, and participant list at least 14 days before opening.

  • Meeting rooms use a pre-conference meeting 15 days before the event to finalize the operation plan, seating, and equipment.
  • A 10% deposit is required before space reservation, followed by staged mid and final payments.
05

Power & cabling

Designated contractor

Electrical work in the exhibition halls follows designated-contractor rules, and local lighting may not exceed 100W per square meter.

  • Booth wiring, lighting, and heating equipment are installed by COEX-designated contractors.
  • The regulations spell out main-breaker, grounding, and distribution requirements.

Waste & cleaning

Organizer responsibility

Non-recyclable waste may not be piled on the loading dock, and the organizer is responsible for cleanup and disposal.

  • After the event, food waste, decorations, and debris should be removed on schedule.
  • Waste left at the loading dock can be treated as a rule violation.

Unknowns stay explicitly unknown.
