Everything you need to know about Seoul's subway system — buying tickets, using T-money cards, reading maps, and navigating transfers. The easiest way to get around Seoul.
Seoul's subway system is one of the best in the world — clean, affordable, on time, and surprisingly easy to navigate as a foreigner. With 23 lines covering over 1,000 stations across the Seoul Metropolitan Area, it reaches virtually every major attraction, shopping district, and neighborhood.
All stations have signage in Korean, English, Chinese, and Japanese. Announcements are bilingual (Korean + English). You can get almost anywhere in central Seoul for under 2,000 KRW — making the metro the fastest and cheapest way to explore the city.

Buy a T-money card at any convenience store (CU, GS25, 7-Eleven) near the airport or subway station for 3,000 KRW (character designs 4,000–5,000 KRW). Charge it at the top-up machines inside stations — they have English menus. T-money works on all subways, buses, and even some taxis. You can also use a mobile T-money via Samsung Pay or Apple Pay (Korea-issued cards only).
Use Naver Map or KakaoMap (Google Maps is limited in Korea). Type your destination and the app shows exact subway routes, transfer stations, exit numbers, and real-time arrival info. Subway lines are color-coded: Line 1 (dark blue), Line 2 (green circle line), Line 3 (orange), Line 4 (sky blue), and so on.
Hold your T-money card to the reader at the turnstile until you hear the beep. The screen shows your remaining balance. If using a single-use ticket, insert it into the slot. The gates clearly show arrows for entry and exit — follow the flow.
Look for your line number and direction signs. Platforms show the next station name and the terminal station (final destination) so you know you're heading the right way. LED displays above the platform show arrival times.
At transfer stations, follow the color-coded signs for your connecting line. Transfers are free within the system — just walk through the connecting corridors without tapping out. Some transfer walks are long (Dongdaemun History & Culture Park is notorious) so allow a few extra minutes.
Tap your T-money card at the exit gate. The fare is calculated by distance. Check which exit number you need — major stations have 10+ exits and the wrong one can put you 500m away from your destination.
