First Time in Korea? 20 Things to Know Before You Go (2026 Guide)

Your flight to South Korea is booked.

You're imagining the neon lights of Seoul, the smell of Korean BBQ, beautiful royal palaces, and cafés you've seen online.

You're excited.

But somewhere between booking your hotel and packing your suitcase, the questions begin.

Will your credit card work? Do you need a visa? Can you use Google Maps? What happens if you can't read Korean?

And what if you accidentally break a local rule you didn't even know existed?

If this is your first trip to Korea, this guide is for you.

These 20 practical tips focus on the small details that can make a big difference between a stressful arrival and a smooth adventure.

Quick Answer: What Should You Know Before Visiting Korea?

Before your first trip, check your passport and entry requirements, confirm whether you need an e-Arrival Card, prepare mobile internet access, save your hotel address in Korean, and arrange a reliable payment method.

Download a Korea-friendly navigation app, learn a few polite expressions, and save local emergency numbers.

Most importantly: don't assume the systems you use at home work exactly the same way in South Korea.

Before You Fly: The First 5 Things to Check

01 · Entry documents

1. Check Your Passport and Entry Eligibility

Before you worry about restaurants or sightseeing, confirm that you can enter South Korea with your passport.

For eligible US passport holders traveling for short-term tourism, visa-free entry may be available. But the rules depend on your nationality, purpose of visit, and personal circumstances.

Check passport validity, any applicable visa requirements, and the permitted length of stay using official government sources.

Common mistake: Assuming every passport holder has the same entry rules.

Do this: Check official entry requirements before booking nonrefundable travel.

02 · K-ETA

2. Don't Pay for K-ETA Without Checking the 2026 Exemption

This is especially important for American visitors.

As of October 2026, US citizens are among the nationalities covered by the temporary K-ETA exemption.

The announced exemption runs through December 31, 2026.

That does not mean every traveler is exempt from all entry documentation.

K-ETA and the arrival card are different requirements.

2026 travel alert

If you're traveling in 2027 or later, do not assume the 2026 exemption still applies.

Check the official K-ETA website before departure.

Common mistake: Paying an unofficial website for authorization you may not need.

Do this: Check your exemption status on the government website.

03 · Arrival declaration

3. Know Whether You Need the Free e-Arrival Card

South Korea operates an electronic arrival declaration system.

Travelers who are required to submit an arrival card can complete the e-Arrival Card online within three days before arriving in Korea.

The official service is free.

Some travelers, including holders of valid K-ETA, are exempt from the arrival-card requirement.

A temporary K-ETA exemption, by itself, does not automatically remove the arrival-card requirement.

Common mistake: Using a fake website that asks for a payment.

Do this: Use only www.e-arrivalcard.go.kr and check whether submission is required for your situation.

04 · Medication

4. Check Medication Rules Before Packing

Some medicines that are legal in the United States may be restricted when brought into Korea.

This is especially important for certain controlled or psychotropic medications.

Depending on the medicine, you may need advance permission from the relevant Korean authority.

Do not assume a US prescription automatically authorizes importation.

Common mistake: Packing restricted medication without checking Korean rules.

Do this: Review the Ministry of Food and Drug Safety guidance well before departure.

05 · Hotel details

5. Save Your Hotel Address in Korean

Imagine arriving after a long international flight.

You're tired, your phone battery is low, and a taxi driver asks where you want to go.

Having only the hotel's English marketing name may not be enough.

Save the full Korean address, phone number, and booking confirmation.

Common mistake: Relying on a single screenshot with no Korean address.

Do this: Save your hotel details offline and keep a second copy.

A little preparation before departure can prevent stressful moments after arriving in Korea.

Your Phone, Money and Everyday Travel

06 · Internet

6. Arrange Mobile Data Before You Need It

Your smartphone may become your most important travel tool.

You'll use it for directions, translation, reservations, transportation and messaging.

Possible options include an international roaming plan, a Korean SIM card, an eSIM or portable Wi-Fi.

Check that your phone supports the option you choose.

Common mistake: Landing without internet access and discovering your phone cannot use the eSIM you purchased.

Do this: Confirm device compatibility and save your installation instructions.

07 · Navigation

7. Don't Rely on Google Maps Alone

Google Maps may not provide the same complete navigation experience in Korea that you're used to in the US.

Many travelers also use Naver Map or KakaoMap for local navigation.

Download an alternative before your trip, and practice searching for your hotel.

Common mistake: Assuming one familiar map app will handle every walking and transit route.

Do this: Install Naver Map or KakaoMap and test it before departure.

08 · Translation

8. Keep a Translation App Ready

You don't need to speak fluent Korean to enjoy your first visit.

But translation tools can help with menus, instructions and unexpected situations.

Papago and other translation apps may be useful.

Remember that automated translations can make mistakes.

Common mistake: Assuming every restaurant and small business has an English menu.

Do this: Save essential phrases and test camera translation.

09 · Payments

9. Bring a Payment Card, but Keep Some Korean Won

Many businesses in Seoul accept payment cards.

Still, some markets, small vendors or payment systems may work differently.

Your foreign card may also incur international transaction fees.

Carry a modest amount of Korean won as a backup.

Common mistake: Depending on one credit card for every purchase.

Do this: Carry a backup payment method and check card fees.

10 · Transit cards

10. Understand That a Transportation Card Is Different From Your Bank Card

You may use a transportation card such as T-money for eligible subway and bus journeys.

Buying or recharging a transit card can involve payment rules different from ordinary shopping.

Do not assume every international credit card can reload every card at every machine.

Common mistake: Arriving at a station without a usable payment method for transportation.

Do this: Learn how to buy and recharge your chosen transportation card.

Getting Around Without Common Tourist Mistakes

11 · Airport arrival

11. Choose Your Airport Transfer Before Landing

After a long flight, you may not want to compare unfamiliar routes while standing in an airport.

Your best transfer depends on your hotel, arrival time and luggage.

An airport train, limousine bus or taxi may make sense in different circumstances.

Common mistake: Choosing the fastest-looking train without checking its stops.

Do this: Save your hotel-specific route before boarding the plane.

For a detailed comparison, read our Incheon Airport to Hongdae guide .

12 · Last train

12. Don't Assume Public Transportation Runs All Night

Seoul has extensive public transportation, but subway service does not run continuously through the night.

Late arrivals, long dinners or nightlife can change your return options.

Common mistake: Staying out late without checking the last train.

Do this: Check your actual route and last departure time on the day you travel.

13 · Addresses

13. Double-Check the Exact Destination

Seoul has many businesses with similar names, multiple branches and entrances on different streets.

The restaurant or café you saw online might not be the branch closest to your hotel.

Common mistake: Following the name of a business without verifying the address.

Do this: Confirm the Korean address, branch and entrance before leaving.

14 · Walking

14. Wear Comfortable Shoes and Plan for Hills

A day in Seoul can involve substantial walking, stairs and sloped streets.

Some subway stations have long passageways between exits and platforms.

The shortest-looking route may not be the easiest one with luggage or mobility needs.

Common mistake: Planning too many distant stops without considering walking time.

Do this: Group nearby attractions and check accessible exits when needed.

Korean Culture: Small Details That Matter

Understanding a few local customs can make your first Korea trip more comfortable and respectful.

15 · Etiquette

15. Learn a Few Polite Korean Expressions

Even a few Korean words can make everyday interactions feel warmer.

• Annyeonghaseyo: Hello.
• Gamsahamnida: Thank you.
• Joesonghamnida: I'm sorry.
• Juseyo: Please give me / please.

You don't need perfect pronunciation.

A respectful attitude matters more than memorizing dozens of phrases.

Common mistake: Feeling embarrassed and avoiding all communication.

Do this: Practice a few polite expressions and keep a translation app handy.

16 · Indoor customs

16. Know When to Remove Your Shoes

Shoes are commonly removed inside Korean homes and some traditional accommodations, restaurants and cultural spaces.

Look for shoe racks, raised flooring or posted instructions.

Not every indoor space requires removing shoes.

Common mistake: Walking into a shoes-off area without noticing the entrance.

Do this: Pause at the entrance and follow the local signs.

17 · Restaurant habits

17. Understand That Restaurant Service Can Work Differently

At some restaurants, you order at a counter or use a table-side device.

Water and side dishes may be self-service.

Tipping is not generally expected in ordinary Korean restaurant service.

Always follow any specific payment or service instructions at the business.

Common mistake: Waiting for table service at a self-service restaurant.

Do this: Look for ordering screens, call buttons and posted instructions.

18 · Photography

18. Respect People, Private Spaces and Cultural Sites

South Korea offers wonderful photography opportunities.

But not every street, shop or cultural location is an unrestricted photo zone.

Bukchon Hanok Village, for example, includes residential areas where visitor behavior and access restrictions matter.

Rules can change, so check current signs.

Common mistake: Treating residential streets like a film set or photographing strangers without consideration.

Do this: Respect quiet hours, private property and photography restrictions.

Safety and the Final Details

19 · Emergency help

19. Save Korean Emergency Numbers Before Your Trip

You may never need them, but it's important to know where to turn if something goes wrong.

112 — Police

119 — Fire and emergency rescue

1330 — Korea Travel Helpline

For urgent medical emergencies, 119 is an emergency response number.

The 1330 tourism helpline can help with travel questions and interpretation support.

Common mistake: Not knowing whom to contact when your phone, passport or belongings are lost.

Do this: Save emergency contacts and your embassy's details offline.

20 · Final preparation

20. Make a Backup Plan for Your First 24 Hours

Imagine arriving in Seoul and discovering your phone has no mobile data.

Or your card doesn't work.

Or your hotel can't find your reservation immediately.

None of these problems has to ruin your trip.

Prepare a small offline arrival kit.

• Passport and travel documents
• Hotel address in Korean
• Booking confirmation
• Airport transfer instructions
• Backup payment method
• Emergency phone numbers
• Offline copies of essential details

Common mistake: Keeping every important document inside one app that requires internet access.

Do this: Save offline copies and keep critical details in a second location.
