Public transportation in Korea is generally easy to use once you understand the basic system.
Subways and buses cover most places visitors are likely to go, and transportation cards such as Tmoney and EZL make paying for rides much simpler.
For most visitors, the easiest setup is to get a transportation card, add some Korean won to it, and use the same card for both subways and buses.
The main things you need to know are how to get a transportation card, how to use it correctly, and how transfers work.
What Do You Need to Use Public Transportation in Korea?
For most travelers, the easiest option is to use a reloadable transportation card.
Tmoney and EZL are two of the most common choices. You can purchase and reload them at convenience stores across Korea and use them on subways, city buses, and many other forms of public transportation.
You can also buy a single-journey ticket when using the subway, but this is less convenient if you plan to take public transportation regularly.
In most cases, getting a transportation card soon after you arrive will make getting around much easier.
How to Use the Subway
Using the subway is straightforward once you have a transportation card.
When entering a station, tap your card on the reader at the ticket gate. The fare is automatically deducted from your card balance.
Follow the signs for the correct subway line and direction, then tap your card again at the gate when you leave your destination station.
Most major subway systems provide station signs and announcements in English, making them relatively easy to navigate even if you do not speak Korean.
If you do not have a transportation card, you can also purchase a single-journey ticket at a subway station. These tickets are for subway travel only, so a reloadable transportation card is usually more convenient if you plan to use buses as well.
How to Use Buses
Buses can seem a little more complicated than the subway at first, but the basic process is simple.
When you board, tap your transportation card on the card reader. In Seoul, passengers normally board through the front door.
When your stop is approaching, press one of the stop buttons inside the bus. Before getting off, tap your transportation card again on the reader near the exit.
Tapping your card when you get off is especially important if you plan to transfer to another bus or the subway, because it allows the transportation system to calculate your transfer correctly.
Bus routes and boarding locations can sometimes be confusing, so checking your route in a navigation app before you board can make the trip much easier.
How Do Transfers Work?
One of the advantages of using a transportation card in Korea is that transfers between buses and subways can be automatically discounted.
In Seoul, you normally need to transfer within 30 minutes after tapping out of your previous ride. Between 9 PM and 7 AM, the transfer window is extended to 60 minutes.
To receive the transfer discount, make sure you use the same transportation card throughout your trip and tap your card when getting off a bus.
The system automatically calculates the fare based on your journey, so you do not need to buy a separate transfer ticket.
Transfer rules can vary slightly between cities, so the exact conditions may be different outside Seoul.
Which Transportation Card Should You Get?
For most visitors, either Tmoney or EZL is a practical choice.
Both cards can be used on subways and buses across much of Korea, so you do not need a different transportation card every time you visit another city.
Tmoney is especially familiar to many visitors and is easy to find, but EZL works in many of the same situations. Unless you have a specific reason to choose one over the other, either card will work well for everyday travel.
Transportation cards can be purchased and reloaded at convenience stores and other authorized locations.
The most important thing is simply to have a card with enough balance before you travel.
What About the Climate Card?
If you are staying mainly in Seoul and expect to use public transportation frequently, the Climate Card may be worth considering.
Short-term Climate Card passes are available for 1, 2, 3, 5, or 7 days and allow unlimited rides within the card’s designated service area during the valid period.
The Climate Card mainly covers Seoul subway lines and Seoul-licensed buses, so it is important to check the service area if you plan to travel outside Seoul.
Short-term passes are particularly useful for visitors who expect to take several subway or bus rides each day.
Since March 2026, international credit and debit cards such as Visa and Mastercard can also be used at new ticket machines on Seoul Metro Lines 1–8 to purchase or recharge short-term Climate Cards.
How to Find the Right Route
A navigation app can make using public transportation in Korea much easier.
NAVER Map is a useful option for finding subway and bus routes, checking estimated travel times, and locating the correct station or bus stop.
The app supports English, so you can search for destinations and follow public transportation directions without needing to read Korean.
Before starting your trip, check the recommended route, the direction of the subway line or bus, and where you need to transfer.
For buses in particular, checking the bus number and boarding location before you arrive at the stop can help avoid confusion.
The Easiest Setup
For most visitors, there is no need to make public transportation complicated.
A simple setup will cover most everyday trips:
- Get a Tmoney or EZL transportation card after you arrive.
- Add enough balance for your trips.
- Use the same card when riding subways and buses.
- Remember to tap your card when getting off a bus, especially when transferring.
- Use a navigation app such as NAVER Map to check your route before you travel.
Transportation cards can be purchased and reloaded at convenience stores across Korea, making them easy to use even if you are visiting for only a short time.
Once you have a card and know how to tap in and out, using public transportation in Korea becomes much easier.
The Bottom Line
Public transportation in Korea is easy to use once you understand the basics.
For most visitors, a Tmoney or EZL transportation card is the simplest way to travel by subway and bus. Use the same card throughout your trip, remember to tap when entering and exiting where required, and check your route with a navigation app before you travel.
If you are staying mainly in Seoul and plan to use public transportation frequently, a short-term Climate Card may also be worth considering.
With a transportation card and a little familiarity with the system, you can get around Korea comfortably without needing a car.
