Can I use my credit card to pay for the subway?

Not directly at the turnstiles. You must use a T-money card or a WOWPASS, which functions as both a prepaid card and a currency exchange.

Is the subway open 24 hours?

No. The subway typically runs from 5:30 AM until midnight. Check the specific train schedule on your app for the last departure time.

Are there elevators in every station?

Most stations have elevators, but they can be slow and located at only one end of the station. Look for 'Elevator' signs if you have heavy luggage.

How to navigate the Seoul subway system like a local

Buy a T-money card at any convenience store or subway station kiosk immediately upon arrival. Use the 'Subway Korea' or 'Naver Map' app to track your route in real-time, as Google Maps does not provide accurate public transit directions in Seoul.

Get a T-money card. Go to any 7-Eleven, GS25, or CU convenience store and ask for a 'T-money card.' It costs 2,500 to 4,000 KRW for the card itself. Load it with at least 20,000 KRW to start.
Install the right navigation apps. Download 'Naver Map' or 'Subway Korea.' Set the language to English. These apps will show you which subway car is closest to the exit stairs or transfer platform, saving you time.
Master the platform gates. Check the station number (e.g., 202) and the direction of the final station on the line. Ensure you are entering the gate that leads to the correct direction, as some stations have separate entrances for each platform.
Tap in and out. Tap your T-money card on the circular sensor at the turnstile when entering and exiting. If you don't tap out, you will be charged a penalty the next time you try to use the card.
Transferring lines. Follow the colored floor lines that correspond to the subway line you are transferring to. If you transfer within 30 minutes, your journey is calculated as a single trip, saving you money.
