Most people find out about K-ETA at check-in. The airline agent asks for it, you’ve never heard of it, and your flight leaves in three hours.
Don’t be that person.
K-ETA — Korea’s Electronic Travel Authorization — is a mandatory pre-entry requirement for citizens of 112 visa-free countries. It’s not a visa. It doesn’t go in your passport. But without it, you can’t board a plane to South Korea.
Here’s everything you need to know.
What K-ETA Actually Is
K-ETA is South Korea’s version of the US ESTA or Australia’s ETA. You apply online before your trip, get approved, and that approval is linked to your passport. No sticker. No stamp. The airline and immigration officers check it electronically.
If your country doesn’t require a visa for Korea, you almost certainly need a K-ETA instead. The two are mutually exclusive — you need one or the other, not both.
It costs $10 USD, takes roughly 72 hours to process (often faster), and stays valid for two years or until your passport expires, whichever comes first. During that window, you can enter Korea multiple times without reapplying.
Who Needs It — and Who Doesn’t
K-ETA applies to citizens of 112 countries that have visa-free agreements with South Korea. That includes the US, UK, Canada, Australia, most EU countries, Japan, and many others.
You do not need K-ETA if you already have a valid Korean visa — the visa covers entry. K-ETA is only for those entering under visa-free arrangements. You also don’t need it if you’re transiting without going through immigration, though this depends on your nationality and layover length.
How to Apply
Apply only through the official government site: eta.go.kr. There are dozens of third-party sites that charge $40–$80 for the same thing. They are unnecessary. The official site costs $10 and works fine.
The process takes about 10 minutes: go to eta.go.kr → create an account → fill in your personal details, passport information, and travel plan → upload a passport photo → pay $10 → submit.
Apply at least 72 hours before departure. In practice, apply the moment you book your flight.
What the Application Asks For
Passport photo requirements are strict: plain white background, no glasses, face centered, taken within the last six months. Phone photos against a white wall work fine if the lighting is even. Blurry or off-center photos are the most common reason for delays.
Planning a trip to Korea?
Check our guides on where to go, getting a SIM card, and K-ETA requirements before you fly.
Accommodation address: You need a Korean address for your first night — hotel, Airbnb, or a friend’s place. Use the address from your booking confirmation.
Travel purpose: Most applicants select “Tourism.” Be accurate. Selecting the wrong purpose can cause problems at immigration.
K-ETA Approval and What It Looks Like
Once approved, you’ll get an email with your authorization. Save this email and download the PDF. Having it on your phone is enough — no need to print.
Your K-ETA is tied to your passport number. If you renew your passport before your trip, your K-ETA becomes invalid and you’ll need to reapply.
If Your Application Gets Rejected
Rejections happen. Common reasons: incomplete information, a photo that didn’t meet requirements, or prior immigration issues in Korea. You’ll receive a notice explaining why, with guidance on next steps.
At the Airport and Immigration
Korean immigration officers verify K-ETA electronically. You don’t need to hand over any paperwork — it’s already in the system. Just present your passport as normal.
Immigration officers can ask questions and have discretion over entry. Having your accommodation address, return ticket, and travel documents ready answers most questions before they’re asked.
