K-ETA vs Arrival Card
The K-ETA (Korea Electronic Travel Authorization) is a pre-approval for visa-exempt travelers, while the Arrival Card is a declaration of health/entry info.If your nationality requires the K-ETA (small fee required), you are exempt from the Arrival Card. If you are exempt from the K-ETA, you must fill out the Arrival Card.
Citizens of many countries such as the USA and the UK, are exempt from filling out the K-ETA and only need to fill out the FREE Arrival Card. This has been marked as temporary, but they keep pushing out the temporary exemption period. Currently it's set to end late 2026.
For either form, if your travel plans change, you should update the information before arrival. You can go so on either of the links provided below, or via the link they will send you in an email after you submit the form initially.
Check which form you are required to submit.
E-Arrival Card
Only submit this form if you are exempt from the K-ETA.You can fill in the paper form once you arrive at the airport, or fill it out online up to 72 hours before landing, to avoid filling out a paper card on the plane or at the airport.
There is no fee! It's easy to accidentally click on a third party link disguised as the official government link. If you see a fee, use the link I have provided here. Or possibly if you see a fee of 10,000 South Korean won, you might be on the K-ETA form.
South Korea E-Arrival Card official government page
Choose your language in the top right corner. On the first page, you must agree to all in order to proceed.
Enter all the information they ask for. Select your airline first and it will automatically add the first two letters of the flight number.
When it comes to the address where you are staying, unless you are writing in Korean, choose English. I usually just Google the address of my hotel and put the first part of it in, minus Incheon, South Korea. Click the find button and if you entered it correctly, and address or more will come up in a drop down for you to select from.
If you are just transiting but have to exit security, I enter the address of the airport.
That's pretty much it. Once you submit it it will likely approve it on the spot with a link to download or print it. You did not however have to bring it with you to immigration. They have it on electronic file.
You will be emailed a link to it in case you need to make changes before your arrival.
