K-ETA (Korea Electronic Travel Authorization) is South Korea's pre-departure electronic authorization for visa-exempt entry. The system was rolled out in stages from 2021 and made mandatory for most Western visa-exempt nationalities in 2024.
Practical rules (as of 2026): - **Most Western nationalities** (US, UK, EU, Australia, Canada, Japan, etc.) require K-ETA for visa-free entry into Korea, even for short tourist visits - **K-ETA must be applied for online** before departure at the official portal (k-eta.go.kr); paper applications are not accepted - **Approval is typically near-instant** for clean applications; some applications go to manual review and take 24-72 hours - **K-ETA is valid for 3 years** or until the holder's passport expires (whichever is earlier); multiple entries permitted - **Transit passengers staying airside under 24 hours** generally do not need K-ETA — the standard airside-transit exemption applies
Implications for premium-cabin connecting traffic via Incheon (ICN): - **Connecting through ICN** without leaving the airside transit area: K-ETA not required, standard airside-transit rules apply - **Stopover in Seoul** during a layover (leaving the airport landside): K-ETA required, must be obtained before departure - **First-time visitors** should expect to apply for K-ETA in the days before departure; not at the airport
Note that K-ETA requirements have been adjusted multiple times since 2021 — the K-ETA waiver list (countries temporarily exempted from K-ETA) has been added and removed at various times. Verify the current requirement for the specific passport before assuming exemption.
K-ETA replaces the historic Korea Tourist Card system and operates alongside (not in place of) standard tourist visa requirements for non-visa-exempt nationalities.
