Do You Need a K-ETA for a Layover in Korea? (2026 Transit Rules)
If Korea is just a stop on the way, you probably don't need to do the full K-ETA dance — but it depends on one thing: do you leave the airport or not? Stay airside and you usually need nothing. Step out into the city and the normal entry rules kick in. Here's the clean version for 2026, plus where to confirm your exact case.

The short answer
Pure airside transit usually needs nothing — not a K-ETA, not a visa, not the e-Arrival Card. You travel on your passport and onward boarding pass. The moment you leave the airport and clear immigration, you've entered Korea, so the standard rules apply: you'd need a K-ETA unless your nationality is on the temporary exemption list. Confirm your exact case on the official site and with your airline at check-in.
Two situations, two answers
| Your layover | What you typically need |
|---|---|
| Stay airside, connect to your next flight | Usually nothing — passport and onward boarding pass |
| Leave the airport to enter Korea | Treated as a normal arrival: K-ETA unless exempt, plus any arrival paperwork |
A general framework, not a personal ruling. The deciding factor is whether you pass through immigration. Confirm on the official K-ETA site for your nationality and route.

Where to confirm (official only)
Transit rules depend on nationality, layover length, and whether you leave the airport — and they can change. The reliable sources are the official K-ETA portal and your airline at check-in.
Staying online during a layover
Even airside, a long layover is easier with data — to check gate changes, message family, or look up your onward connection. A prepaid travel eSIM installs before your trip and activates when you connect to a Korean network, so you're online the moment you land without buying anything at the airport.
Frequently asked questions
Do I need a K-ETA for a layover in Korea?
If you stay airside and don't pass through immigration, generally no — just your passport and onward boarding pass. If you leave the airport to enter Korea, normal entry rules apply and you may need a K-ETA unless exempt.
What if I want to leave the airport on a long layover?
That means clearing immigration and entering Korea, so you'd be treated as a regular arrival: a K-ETA unless your nationality is exempt, plus any arrival paperwork. Confirm on the official site first.
Do I need a K-ETA to change terminals at Incheon?
Moving between terminals as a transit passenger without entering Korea normally doesn't require a K-ETA on its own. Confirm the transit procedure with your airline at check-in.
Does the exemption apply to transit passengers?
For airside transit you typically need nothing regardless of nationality. The exemption matters when you actually enter Korea, so if you exit the airport, your nationality's status decides whether a K-ETA is required.
How do I confirm my exact transit requirement?
Check the official K-ETA website and confirm with your airline at check-in, since rules depend on nationality, layover length, and whether you leave the airport, and the airline applies current rules for your route.
