Practical Tips for Exhibition Visitors
- Registration: Most COEX exhibitions offer pre-registration online. Do it — badge pickup lines for walk-ins can be 30–45 min long.
- Wi-Fi: Free COEX Wi-Fi throughout halls, but it gets congested. A Korean SIM card or pocket Wi-Fi is worth it for reliable connectivity. Buy at Incheon Airport on arrival.
- Currency: Korea is increasingly cashless. Visa/Mastercard accepted almost everywhere in COEX and the mall. Still keep ₩50,000–100,000 cash for small vendors on the exhibition floor.
- Language: COEX staff at information desks speak functional English. Exhibition booth staff vary — major international shows have English speakers; domestic B2B shows may not. Google Translate camera mode is your friend.
- Luggage storage: Coin lockers at Samseong Station exits and inside COEX mall. ₩2,000–4,000 for small to large. Useful if you’re arriving or departing the same day as the exhibition.
- Dress code: Business casual is standard for trade shows. Consumer expos are more relaxed. Check the specific event guidelines.
- Best time to visit halls: First 30 min after opening (less crowded) and 1.5 hrs before closing (exhibitors more relaxed, better conversations).
