Korea e-Arrival Card & Q-Code: Do You Still Need Them for Entry?

A lot of travelers arriving in South Korea in 2026 are working off outdated information — blog posts from 2023 saying you don’t need K-ETA, or forum threads asking about Q-Code like it’s still 2021. The entry rules genuinely shifted at the start of 2025, and if you flew to Korea during the waiver period and are planning to return, your last experience no longer reflects what’s required. Here’s exactly what you need, what you can skip, and what to do in what order.

What Changed on January 1, 2025 (and Why It Matters for Your 2026 Trip)

From April 1, 2023 to December 31, 2024, South Korea ran a temporary K-ETA waiver for nationals from 22 countries and territories. That waiver ended. As of January 1, 2025 — and throughout all of 2026 — those nationalities need K-ETA again before boarding a flight to Korea.

The 22 countries and territories where the waiver has expired are: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Italy, Japan, Macau, Netherlands, New Zealand, Norway, Poland, Singapore, Spain, Sweden, Taiwan, the United Kingdom, and the United States (including Guam, Saipan, and American Samoa).

If you traveled to Korea in 2024 from any of those places without applying for K-ETA, that experience will not repeat itself in 2026. Airlines check K-ETA authorization before boarding. Showing up at the gate without one means you do not get on the plane.

All other visa-waiver nationalities that were already subject to K-ETA before the temporary waiver — and were never part of the 22-country exemption — continue to require it as well. The reinstatement of K-ETA for the 22 countries is simply the biggest change affecting the most travelers right now.

K-ETA: Who Needs It, Who Doesn’t, and How to Apply

K-ETA is South Korea’s electronic travel authorization — similar to the US ESTA or Canada’s eTA. It is required for nationals of visa-waiver countries entering Korea for short stays (tourism, business visits, transit with exit from the airport). It is not a visa, and it does not replace a visa if you need one.

Who is exempt from K-ETA

• Holders of a valid Republic of Korea visa
• Korean nationals
• APEC Business Travel Card holders with “KOR” printed on the back
• Flight and ship crew members
• Transit passengers who remain in the international transit area without clearing immigration
• UN passport holders
• Certain diplomatic and official passport holders

How to apply for K-ETA

1. Go to www.k-eta.go.kr or download the official K-ETA mobile app (iOS and Android). Use only the official site — there are third-party services charging inflated fees for the same application.
2. Select your language and agree to the terms.
3. Enter your passport details: nationality, passport number, expiry date.
4. Fill in personal information: name, date of birth, gender, occupation, contact details, purpose of visit.
5. Upload a passport-style photo with a plain background.
6. Provide your intended address in Korea — a hotel name and address is fine.
7. Answer the declaration questions about criminal history and previous immigration violations.
8. Review everything carefully, then pay the fee.

The fee is KRW 10,000 per person (approximately USD 7–8 at 2026 exchange rates). It is non-refundable regardless of outcome. Processing typically takes 24 to 72 hours, but apply at least 72 hours before your flight — preferably several days earlier. Approval comes by email. Once approved, your K-ETA is valid for three years from the approval date and covers multiple entries, as long as your passport remains valid. The maximum stay per entry depends on your nationality, usually 30, 60, or 90 days.

Q-Code in 2026: The Short Answer Is No — But Here’s the Full Picture

Q-Code was South Korea’s pandemic-era health pre-registration system. Travelers would enter health information and travel history before arrival at cov19ent.kdca.go.kr, receive a QR code, and present it to health officials at the airport.

Since July 15, 2023, all COVID-19 entry restrictions have been lifted. Q-Code is not required in 2026. There are no health declaration forms, no temperature checks on arrival, and no quarantine requirements for any traveler entering Korea regardless of vaccination status.

The Q-Code system technically still exists online. Some travelers voluntarily use it, and the government has kept the infrastructure in place in case of future health events. But for a standard 2026 trip to Korea, it adds no benefit and is not part of your entry process. You do not need to think about it.

The Paper Immigration Arrival Card: Still a Thing in 2026

Despite how digitized Korea’s systems have become in many areas, the paper immigration arrival card is still the standard requirement for most foreign nationals arriving in 2026. Korea has expanded its Smart Entry Service — automated immigration gates using fingerprints and facial recognition — but this system is currently open only to Korean citizens and registered foreign residents who have pre-enrolled their biometric data.

For everyone else, the process at the general immigration counter involves presenting your passport, your completed paper arrival card, and your K-ETA approval (or visa). The arrival card asks for your full name, date of birth, gender, nationality, passport number, flight number, intended address in Korea, purpose of visit, and duration of stay.

You will usually find these cards distributed on the plane during the flight, or you can pick one up in the immigration hall before joining the queue. Keep a pen in your carry-on bag — it sounds obvious, but the lines at the card-filling station are always longer than they look. Fill it out completely. Immigration officers at Incheon have seen every variation of “I’ll finish it when I get there” and they will send you back to complete it.

Wait times at general immigration counters at Incheon International Airport can range from 15 to 60 minutes depending on the time of day and incoming flight volume. Early morning arrivals from long-haul routes from Europe and North America tend to be the busiest windows.

Customs Declaration: Skip the Paper Form and Use the App

A customs declaration is mandatory for all travelers entering South Korea. But unlike the immigration arrival card, there is a genuinely faster electronic alternative that most travelers are not using.

The Korea Customs Service mobile app (available on iOS and Android) lets you complete your declaration before you land. Once submitted, you receive a QR code. At the airport, you scan it at a dedicated e-Customs gate and walk through — assuming you have nothing unusual to declare. It is noticeably quicker than the paper lane.

How to use the Korea Customs Service app

1. Download the Korea Customs Service app before your trip.
2. Select your language and start a new declaration.
3. Enter your passport number, flight number, date of birth, and nationality.
4. If traveling with family, add their details under accompanying passengers.
5. Answer the declaration questions honestly: currency over USD 10,000, dutiable goods, prohibited or restricted items.
6. Review, submit, and save the QR code to your phone’s photo library as a backup.
7. At the airport, proceed to the e-Customs gate and scan your code.

Airport kiosks in the customs area at major international airports serve the same purpose if you did not complete it in advance. Either way, the paper form remains available as a fallback — but between the kiosk queue and the paper counter, the app completed before arrival is the fastest option by a clear margin. General customs information is available at www.customs.go.kr.

What Happens Step by Step at the Airport

Incheon International Airport is large and well-signposted in English, but knowing the sequence helps — especially after a long-haul flight when the smell of the airport coffee shops and the hum of the baggage carousels start blending together into a tired blur.

1. Disembarkation: Follow signs toward immigration. In 2026, there are no mandatory health screening stops for general arrivals.
2. Immigration: Join the general immigration counter queue. Have your passport, completed paper arrival card, and K-ETA approval ready. Officers may ask brief questions about your visit.
3. Baggage claim: Collect your luggage from the carousel indicated on the screens.
4. Customs: If you used the Korea Customs Service app or an airport kiosk, head to the e-Customs lane and scan your QR code. If you are using the paper form, go to the standard customs lane. Customs officers conduct random checks — if selected, your bags may be inspected regardless of which lane you used.
5. Exit to arrivals hall: Once through customs, you are in the public arrivals area. The T-Money card vending machines, AREX train ticket counters, and taxi booking desks are all within a short walk.

2026 Budget Reality: What Entry Formalities Actually Cost

Most of the entry process costs nothing beyond the K-ETA fee, but here is a clear breakdown so there are no surprises.

• K-ETA application fee: KRW 10,000 (~USD 7–8). Non-refundable. One fee per person. Valid for three years.
• Q-Code: Free. Also not required.
• Paper immigration arrival card: Free.
• Customs declaration (paper form): Free.
• Korea Customs Service app submission: Free.
• Third-party K-ETA services: Avoid. These charge KRW 30,000–80,000 (~USD 22–59) to submit the same application you can complete yourself in under 15 minutes on the official site.

The only mandatory cost for entry formalities in 2026 is the K-ETA fee — and only if your nationality requires it. Budget travelers and comfortable travelers pay exactly the same amount for this step.

Common Mistakes That Slow You Down at Immigration

• Applying for K-ETA through a third-party site. These are not official. You pay more, you hand over your passport data unnecessarily, and if something goes wrong, you have no recourse through the Korean government.
• Leaving K-ETA until 24 hours before departure. The stated processing time is 24–72 hours, but some applications take longer. Apply at least a week out.
• Assuming the 2024 waiver still applies. It ended December 31, 2024. Full stop.
• Not having your Korean address ready. Both the K-ETA application and the arrival card ask for your address in Korea. Have your hotel name and address saved on your phone before you start filling anything out.
• Forgetting to complete the customs declaration before landing. If you do not have the app QR code and the kiosks are busy, you join the paper form queue. Not a disaster, but avoidable.
• Leaving the arrival card blank or incomplete. Officers will send you back. The line does not pause while you find a pen.

Frequently Asked Questions

Do I need K-ETA if I already have a valid Korean visa?

No. If you hold a valid Republic of Korea visa, you are exempt from the K-ETA requirement. Present your visa at the immigration counter as usual. K-ETA is only relevant for travelers entering under visa-waiver arrangements for short stays.

Is Q-Code still required to enter South Korea in 2026?

No. Q-Code has been optional since July 15, 2023, and it remains optional throughout 2026. There are no COVID-19-related entry requirements — no health declarations, no vaccination proof, and no quarantine for any traveler entering South Korea under normal conditions.

How long does K-ETA approval take, and what if it is still pending when I fly?

Standard processing is 24 to 72 hours. If your application is still pending when you try to board, airlines will typically not allow you to fly. Apply at least 72 hours before departure — ideally a week ahead. You will receive your approval status by email and can also check at www.k-eta.go.kr.

Can I complete my customs declaration on my phone before landing in Korea?

Yes. Download the Korea Customs Service app on iOS or Android, complete your declaration in-flight or before your trip, and save the generated QR code. At the airport, use the e-Customs lane to scan your code. It is faster than both the kiosk queue and the paper form lane.

Do children need their own K-ETA application?

Yes. Every individual traveler, including children and infants, who is from a K-ETA-required nationality must have their own K-ETA authorization. Each application costs KRW 10,000 (~USD 7–8) per person. There are no family bundle applications on the official platform.
