How to Buy a Seoul Subway Ticket: Step-by-Step Guide for Foreigners (2026)

Series: K-Travel | Post #3 | Previously: Seoul Subway Decoded — Rush Hour, Signage & What to Expect

If you want to buy a Seoul subway ticket without the fuss, this guide is for you.

It’s 6:00 AM. The alarm goes off. Somewhere in Ilsan, a man puts on his shoes, walks to Juyeop station, and taps his phone at 6:32 — mobile transit card, no fumbling, no ticket machine, no deposit to remember. He hasn’t touched a ticket machine in years.

This post is not for him. This post is for you.

The complete, no-panic, step-by-step guide to buy a Seoul subway ticket — single-use, from machine to platform, with everything in between.

Seoul Metro Ticket Machine: Two Types, One Logic

Seoul Metro ticket machines come in two flavours. There’s the vertical screen model — tall, slightly older, more common on Lines 3 and 4. And there’s the wide horizontal screen model — sleeker, newer, more common on Line 2.

They look different enough to cause a moment of doubt. Don’t let them. The logic inside is identical. The buttons are in the same order. The screens ask the same questions. The machine on Line 3 at Juyeop at 6:30 AM and the machine on Line 2 at Euljiro during lunch hour will take you to the same destination through the same steps.

Both accept cash (bills and coins), credit cards, and debit cards. Both give change. Both speak English. Pick whichever one has the shorter queue and proceed with confidence.

How to Buy a Seoul Subway Ticket: Everything You Need to Know

Step 1 — Switch to English and Select Single Journey Ticket

The first screen you’ll see is the service selection screen — in Korean. Don’t panic. Look for the language options at the bottom: 한국어 / ENGLISH / 日本語 / 中文. Tap ENGLISH and everything switches. From this point forward, the machine is yours.

Once in English, you’ll see five service options laid out as buttons:

Tap Single Journey Ticket and you’re on your way.

Good to know: See that “Free Ticket (Special status)” button? Seniors aged 65 and over ride Seoul Metro completely free — they just need their Korean ID or welfare card. The machine walks them through it separately. If you’re travelling with an older family member who qualifies, this is the button for them.

Step 2 — Search for Your Destination Station

The machine asks how you’d like to search. Three options:

• Station Name — type the name, or browse alphabetically
• Station Number — every station has a number (e.g., Euljiro 3(sam)-ga is 329 on Line 3)
• Route Map — browse visually

Station Name is the easiest for most people. Tap it, start typing your destination, and the machine will suggest matching stations.

Pro tip: Seoul station names are romanised consistently across maps, apps, and machines. What you see on Naver Map is exactly what you type here.

Step 3 — Choose Number of Tickets and Check the Seoul Metro Fare

Here’s where the machine shows you the full breakdown:

Select 1 Ticket for adult (or however many you need). If you’re travelling with children aged 6–12, the child fare is roughly one-third of the adult fare. Under 6 rides free.

The fare varies by distance — Seoul Metro uses a distance-based system. The base fare (first 10km) is ₩1,550 for adults. Beyond that, it adds ₩100 for every additional 5km. My morning commute from Juyeop to Euljiro 3(sam)-ga — about 30km — comes out to ₩1,950 per adult before the deposit. Less than a cup of coffee. Seoul Metro is generous like that.

Not sure why your total looks higher than expected? Here’s the full breakdown:

Real example — Juyeop to Euljiro 3(sam)-ga (approx. 30km):

• Adult: ₩1,550 base + ₩400 extra distance = ₩1,950
• Child: ₩550 base + ₩300 extra distance = ₩850
• Total for 1 adult + 1 child (with 2 deposits): ₩1,950 + ₩850 + ₩1,000 = ₩3,800

Which is exactly what the screen in the photo shows. The machine isn’t overcharging you — Seoul is just bigger than it looks on the map.

Step 4 — Confirm Destination and Total Fare

The machine shows you a summary screen: destination, fare, deposit, total. This is your last chance to check everything before paying. If something looks off, hit Previous. If it’s all correct, tap Next Step.

Step 5 — Pay by Cash or Card (All Major Cards Accepted)

It’s time to buy a Seoul subway ticket using your preferred payment method.

Two options: Cash or Card.

• Card: Tap, insert, or wave — the machine handles contactless, chip, and swipe. International Visa and Mastercard work fine.
• Cash: Bills and coins accepted. Up to 15 bills and 20 coins per transaction. The machine gives change.

The ticket comes out of the slot at the bottom — small, flat, and easy to overlook. It looks like something you’d throw away. Don’t. It’s your key out of the system, and the ₩500 deposit inside it is quietly waiting to become street food.

Step 6 — Tap Your Ticket at the Gate and Head to the Platform

Tap the ticket on the reader at the gate — the same way you’d use a transit card anywhere. Green light, gate opens, you’re in. Head down to the platform, follow the signage for your line and direction, and you’re on your way.

If you’re not sure which platform to take, I covered this in detail in the previous post — the platform signage in Seoul is genuinely excellent and will tell you exactly which direction you need.

Seoul Metro Deposit Refund: How to Get Your ₩500 Back

The deposit is refundable. Every station has a Deposit Refund Device (보증금 환급기) — the machines with the bright blue sign, usually sitting right next to the exit gates. Hard to miss. Insert your used single journey ticket into the slot, and out comes a ₩500 coin.

Notice there are often two machines side by side: one for regular single-use tickets, one for the Climate Card. Check the label on the front panel before you insert — the “NOTICE” sticker shows you which card goes where with a simple O/X diagram.

It’s a small amount, but: street tteokbokki starts at ₩3,000, and three refunded deposits get you halfway there. More importantly — please don’t just throw the ticket away. The deposit system exists to keep single-use cards in circulation. Be the responsible tourist.

Seoul Subway Ticket Machine in Real Life: Euljiro at Noon

Every day around noon, I walk from Euljiro 4-ga to City Hall station through the underground arcade. It’s one of Seoul’s underrated pleasures — a long, quietly buzzing underground corridor that connects several stations and smells, inexplicably, like the 1990s.

And at the Line 2 ticket machine area, there is almost always a queue of foreign visitors. Couples with rolling luggage. Backpackers squinting at the screen. Someone’s grandmother being gently guided through the process by someone who clearly just figured it out themselves five minutes ago.

The Line 2 machines here are the wide horizontal screen variety — newer-looking, slightly more intimidating at first glance. But as I said: same logic, same steps, same result. The screen is bigger; the process is identical.

And if the machine itself feels like too much, there’s usually a large digital information kiosk nearby — touchscreen, multilingual, with a full route map and fare calculator built in. No queue. No pressure. Take your time with it, figure out your destination and Seoul Metro fare, then go to the machine already knowing what to do.

Vertical vs Horizontal: Both Seoul Metro Ticket Machines Work the Same Way

On my way home, I stopped to try the Line 2 horizontal machine properly — the kind I walk past every day but never actually use, being a mobile transit card person since approximately forever.

The interface is cleaner, the touch response is faster, and the payment section is more clearly laid out — Cash on one side, Card on the other, large enough to read without squinting. The coin slot and bill acceptor are clearly labelled with a diagram showing the maximum (15 bills, 20 coins).

Same destination search. Same fare calculation. Same deposit. Same ticket out the bottom.

The machines look different. They are not different. This is a comforting fact about Seoul Metro.

Seoul Metro Ticket Payment Options: Cash, Card, and More

Beyond the Single Journey Ticket: Smarter Options for Longer Stays

If you’re staying longer than a day — and honestly, you should be — the single journey ticket has done its job. Time to graduate.

T-money Card — Buy at any GS25, CU, or 7-Eleven for ₩3,000–5,000, then top up as needed. Slightly cheaper per ride than a single journey ticket, no deposit hassle, works on buses and taxis too. It’s a small piece of plastic that quietly makes Seoul feel a little more like home. This is the baseline recommendation for anyone staying two days or more. Official English guide: eng.tmoney.co.kr.

Climate Card (기후동행카드) — Visitor Pass — Unlimited subway and bus rides within Seoul for a flat fee. Available in 1, 2, 3, 5, and 7-day versions starting from ₩5,000 per day. If you’re the kind of traveller who moves through a city rather than sitting in it — multiple neighbourhoods, spontaneous detours, one more stop just to see — this card is built for you. More info: english.seoul.go.kr.

WOWPASS — An all-in-one card for foreign visitors combining currency exchange, transit, and general payments. One card, less pocket chaos. You’ll see the kiosks in Euljiro and at major stations. More at wowpass.io.

Contactless credit card at the gate — In 2026, most Seoul subway gates accept international contactless cards directly. Tap your Visa or Mastercard at the gate reader and skip the machine entirely. No ticket, no deposit, no queue. Just tap and go — the way the locals wish everyone could.

The Full Commute: From Juyeop Station to Seoul, Step by Step

Let me put the whole thing together the way it actually happened.

6:23 AM. Out the door in Ilsan, green canopy overhead, city not yet awake. Five-minute walk to Juyeop station — the first stop on Line 3, which means I always get a seat. Small luxury. Non-negotiable.

Down the escalator. Seoul Metro ticket machine on the right. Language set to English, destination Euljiro 3(sam)-ga, one adult single journey ticket, card tapped. Total: ₩2,150 (₩1,650 fare + ₩500 deposit). Ticket out the bottom. Gate open. Escalator down.

6:33 AM. Train in four minutes. Right on schedule.

This is the commute. This is the system. And now, so help me, it can be yours too.

Now that you know how to buy a Seoul subway ticket like a local, where will your first stop be?
