🚇 How to Use the Subway in South Korea: T-Money Card, Etiquette & Insider Tips for First-Time Travelers
If you're planning a trip to South Korea, mastering the subway system is one of the smartest things you can do. It’s fast, clean, affordable, and connects nearly every corner of major cities like Seoul and Busan. But if you’re new to Korea, figuring out how to buy a transportation card, navigate the stations, and follow local etiquette can feel overwhelming.
After spending a few weeks hopping between palaces, markets, and hidden cafés via subway, here’s everything I wish I knew before my first ride—plus a few funny stories and tips to help you travel like a local.
🎫 Buying a T-Money Card: Your Key to Korean Transit
The T-Money card is a rechargeable smart card used for subways, buses, and even some taxis. You can buy one at any convenience store (GS25, CU, 7-Eleven) for around ₩2,500. No registration needed—just load it with cash and tap away.
Pro tip: I bought mine at Incheon Airport right after landing. The cashier even helped me load ₩10,000 onto it. I used it daily and still had leftover credit when I left Korea.
🚉 How to Use the Subway: Step-by-Step
- Tap In & Out: At the turnstile, tap your T-Money card on the reader. You’ll hear a beep and see your remaining balance.
- Know Your Line: Seoul has 23 subway lines, each color-coded. Use Naver Map or KakaoMap for real-time directions.
- Platform Signs: Look for signs with the train’s final destination. Trains often run in both directions, so double-check before boarding.
- Exit Numbers Matter: Korean stations have multiple exits. If you're meeting someone or heading to a specific café, note the exit number—it's crucial.
My mistake: I once exited at Exit 1 instead of Exit 6 in Gangnam and ended up walking 20 minutes in the wrong direction. Lesson learned: exit numbers are everything.

🤫 Subway Etiquette: What Tourists Should Know
Korean subway culture is quiet and respectful. Here are a few rules to follow:
- No loud talking or phone calls. I got a few side-eyes for chatting with a friend too loudly.
- Priority seats are sacred. Even if the train is empty, don’t sit in the silver-marked seats unless you’re elderly, pregnant, or disabled.
- Stand on the right side of escalators. The left is for people in a hurry.
- Let people exit first. It’s polite and efficient.
Funny moment: I once blocked the subway door while checking my phone. A local gently nudged me aside without saying a word. It was subtle, but I got the message.

🗺️ Reading Subway Signs: Easier Than You Think
Most signs are in Korean and English, and station names are written in both Hangul and Roman letters. Transfer stations are clearly marked with colored circles, and exit signs are bright yellow.
Tips:
- Look for the “출구” (chulgu) sign—it means “exit.”
- Platform signs show the next few stops, so you can track your progress.
- Digital displays inside trains show the next station in Korean, English, and sometimes Chinese or Japanese.
Helpful app: Naver Map is more accurate than Google Maps in Korea. It shows subway routes, exit numbers, and even walking directions inside stations.
