The 30-second answer
Before you fly: check whether your passport needs a K-ETA (electronic travel authorization) for your nationality, buy an eSIM or plan to pick up a SIM at the airport, and install Naver Map plus your bank's app. After you land at Incheon: clear immigration, withdraw some Korean won or confirm your card works, buy a T-money transit card, and take the AREX train or an airport bus into Seoul. Everything on this page links to a detailed guide, so treat it as your master checklist.
Three things trip up new visitors most: the map app you use at home may not work well here, an overseas card is not a safe way to pay bus fares, and some restaurant kiosks start in Korean. The fixes are Naver Map, a T-money card, and Papago’s camera translation.
Two weeks before you fly
- Check whether your passport needs a K-ETA. It costs KRW 10,000, review usually takes up to 72 hours, and you must hold it before boarding, so two weeks out is the right time. Travelers aged 17 or under or 65 or over, visa holders, and nationalities on the temporary exemption (through December 31, 2026) do not need one; the official site shows an exemption pop-up when you scan your passport.
- Decide how you will get online. An eSIM activated before landing is the least stressful option if your phone is unlocked and eSIM-capable. Physical SIMs and pocket Wi-Fi are available at the airport. See the connectivity guide.
- Tell your bank you are traveling and confirm your card has no regional block. Bring at least two cards on different networks if you can.
- Install a locally supported navigation app and a translation app. This guide uses Naver Map and Papago; map coverage and features change, so test a route near your accommodation before departure. Install a taxi app only after checking its current foreign-account and payment support.
- Book your first night near a subway or airport-bus stop. Arriving after a long flight is not the moment to attempt a three-transfer route with luggage.
K-ETA or e-Arrival card: which one applies to you
These are two separate Ministry of Justice systems, and most short-term visitors need one of them, not both. K-ETA is a pre-travel authorization for visa-free travelers. The e-Arrival card is the online version of the paper arrival form. The e-Arrival site lists travelers holding an approved K-ETA as excluded from filing an arrival card, while visa holders and people exempt from K-ETA are the ones who file it.
| Your situation | K-ETA | Arrival card |
|---|---|---|
| Visa-free nationality, aged 18 to 64 on your entry date, no visa | Required before boarding | Not needed once your K-ETA is approved |
| Nationality covered by the temporary K-ETA exemption | Not required through December 31, 2026 (KST) | File the e-Arrival card |
| Visa-free nationality, aged 17 or under or 65 or over on your entry date | Not required | File the e-Arrival card |
| Holding a valid Korean visa | Not required | File the e-Arrival card (also if you hold a K-ETA but enter on the visa) |
The numbers that matter, from the official K-ETA pages: the fee is KRW 10,000 plus a 3% online payment charge, and it is not refunded if the application is refused. Review usually finishes within 72 hours but can take longer, and there is no express service. An approval is valid for 3 years, or until your passport expires if that comes first, and it covers multiple entries. You need a new K-ETA if you renew or replace your passport. Apply only at k-eta.go.kr or the official K-ETA app; the site itself warns about look-alike agency sites charging high fees for fake express processing.
The Ministry of Justice extended the temporary exemption to December 31, 2026. The notice does not print a country list; instead, if your nationality qualifies, scanning your passport photo page in the K-ETA application brings up a ‘K-ETA exempt’ pop-up. Exempt travelers may still apply and pay the fee if they want the K-ETA benefits, such as skipping the arrival card.
The e-Arrival card is free and opens 3 days before your arrival date in Korea time. It lapses 72 hours after you submit it, or once you pass immigration, so file it close to landing rather than when you pack. On a long-haul flight that lands the next day, count the 3 days back from your arrival date, not your departure date. You can edit it before immigration, but the entry date can only be changed within 3 days of the original filing. A confirmation number is emailed to you; you do not need to print anything.
Three days before you fly
- If you do not have an approved K-ETA (for example, you are K-ETA exempt or you hold a visa), file the free e-Arrival card online. It opens 3 days before your arrival date in Korea time and lapses 72 hours after you submit it, so do it within that window.
- Screenshot your hotel name and address in Korean. You will show this to taxi drivers and use it in map searches.
- Download offline translation packs in Papago and save your embassy's contact details.
- Check the weather. Seoul summers are hot and humid with sudden heavy rain; winters regularly drop well below freezing.
The first 90 minutes after landing
| Step | Where | What you need | Detailed guide |
|---|---|---|---|
| Immigration + arrival card | Arrivals hall | Passport, e-Arrival confirmation if applicable | This page |
| Get online | Gate area (eSIM) or telecom counters | Unlocked phone, passport for physical SIM | eSIM / SIM guide |
| Get cash or confirm card | Global ATMs in arrivals | Debit card with Visa/Mastercard/UnionPay logo | ATM guide |
| Buy T-money card | Convenience store or station machine | Cash for the card and first top-up | T-money guide |
| Travel to Seoul | B1 station (AREX) or bus stops outside arrivals | T-money or a ticket | Airport to Seoul |
A rechargeable transit card such as T-money is the most predictable option for subways and buses. Where it can be bought, loaded, used, or refunded can change by operator and seller, so use the linked guide and current signage rather than treating every shop or payment method as universal.
Money: what actually gets accepted
Cards are widely used in Korean cities, but acceptance of an overseas-issued card is never guaranteed. Keep a second card on another network and a modest cash backup for transit-card top-ups, markets, small shops, or a terminal that rejects your card. The details, including what to do when your card is declined, are in the foreign card guide.
If you plan to shop, read the tax refund guide before your first purchase — refunds require your passport at the till.
When something goes wrong
- Phone has no signal after landing: connect to the free airport Wi-Fi first, then troubleshoot your eSIM or find a telecom counter. Do not leave the airport offline.
- Card declined at the ATM: try a different ATM brand (bank ATMs and convenience-store ATMs behave differently) before assuming your card is blocked.
- Lost luggage or lost items later in the trip: use the airline or transport operator first, then search the police-run Lost112 portal as appropriate. Steps are in the emergency guide.
- Immediate danger, crime, fire, or a medical emergency: call 112 for police or 119 for fire and ambulance. Do not route an emergency through a tourism helpline. For a non-emergency travel or language question, check the current VISITKOREA 1330 page first: KTO posted a January 20, 2026 notice that its helpline call/chat was temporarily unavailable until further notice, so this guide does not assume it will connect.
Korean phrases to show
| Korean | Romanization | When to show it |
|---|---|---|
| 이 주소로 가 주세요. | I jusoro ga juseyo. | Show a taxi driver with your hotel address |
| 영어 하실 수 있나요? | Yeongeo hasil su innayo? | Asking if someone speaks English |
| 티머니 카드 주세요. | Timeoni kadeu juseyo. | Buying a T-money card at a convenience store |
| 충전해 주세요. | Chungjeonhae juseyo. | Asking staff to top up your T-money |
| 도와주세요. | Dowajuseyo. | Asking for help |
When two things go wrong at once
- At check-in, the airline says you have no K-ETA. Apply on the official site right away, but plan for the worst case: review is usually within 72 hours and cannot be expedited, so ask the airline about rebooking rather than paying a site that promises express approval. Applying after boarding or from inside Korea can lead to refusal.
- You filed the e-Arrival card early and your flight was delayed. If more than 72 hours have passed since you submitted it, the card has lapsed. File a new one on e-arrivalcard.go.kr before you reach the immigration desk.
- Your eSIM will not connect and your card is declined at the first ATM. Get online on the free airport Wi-Fi shown on airport signage first, then open your bank app to check for a fraud or regional block before trying a different ATM brand. Try the second card you packed on another network next. Only then buy a physical SIM at a telecom counter, which needs your passport.
- Your K-ETA was approved under an old passport. The official FAQ says a renewed or replacement passport needs a new K-ETA application with the new passport details, so apply again before you fly.
FAQ
Is English widely spoken?
Enough to survive in tourist areas, hotels, and among younger people, but do not count on it in taxis, small restaurants, or markets. Papago plus the show-this-phrase tables in these guides cover the gap.
Should I get won before I fly?
It depends on your cards and arrival time. An airport ATM may accept an overseas card, but acceptance, fees, and exchange rates vary by card issuer and ATM operator. A small won backup can reduce arrival-day risk; compare the options in the ATM guide.
Is Korea safe for solo travelers?
Use the same precautions you would in any large city: stay aware of your surroundings, keep your accommodation address offline, and leave a place that feels unsafe. Call 112 for an immediate safety threat. For a non-emergency language or tourism question, confirm that 1330 call/chat is currently available on the official VISITKOREA page before relying on it.
How many days do I need for a first trip?
Most first-timers base themselves in Seoul for 4–7 days, with day trips. If you have 10 or more days, adding Busan by KTX train is the most popular extension.
