Seoul Subway Guide for Tourists: First Ride Checklist
You only need four pieces of information before walking through the gate: your line, the direction of travel, any transfer station, and your destination exit number. A route-planning app can calculate the journey, but you should still read the station signs as you move through the system.
- Line: confirm the line number, name, and color.
- Direction: check which terminal or next stations are shown for your platform.
- Transfer: note the station where you need to change lines.
- Exit: check the numbered exit closest to your destination.
If you remember one rule, make it this: confirm the platform direction before boarding.
Enter the Subway With T-money or a Ticket
For most tourists, a rechargeable transportation card is the easiest option. Tap the card on the reader at the entry gate and use the same card again when you leave at your destination. If you do not have a transportation card, every station has machines for single journey tickets.
Seoul currently lists the adult base fare at ₩1,550 with a transportation card. A single journey ticket is ₩1,650 for the same base fare and also requires a refundable ₩500 deposit.

Choose the Correct Platform Direction
The most common first-ride mistake is entering the right line but taking the train in the wrong direction. Before boarding, compare your destination with the station names or terminal direction shown on the platform signs.
- Match the line color and number first.
- Check the next station or terminal direction on the platform sign.
- If you are unsure, compare the next one or two station names with your route before boarding.
How to Transfer Between Subway Lines
At a transfer station, stay inside the paid area and follow the signs for the line you need next. Transfer signs use line numbers, colors, arrows, and station names. You normally do not tap out just to change subway lines.
Some major transfer stations involve a long walk even though you stay inside the paid area. Allow extra time if you have luggage or limited mobility.
Check the Exit Number Before Leaving
Large Seoul subway stations can have many exits, so treat the exit number as part of the route. The wrong exit can leave you on the opposite side of a large road or several blocks from your destination.
- Check the exit number before you reach the turnstile.
- Follow the numbered exit signs through the station.
- Tap out at the gate, then continue following the same exit number.
Using a Single Journey Ticket
If you do not want to buy a transportation card, use a single journey ticket machine. Seoul says these machines support foreign-language settings. You pay the fare plus a ₩500 deposit. After reaching your destination, insert the ticket into a deposit refund device to get the deposit back.
For repeated rides, a transportation card is usually easier than buying a single journey ticket each time. The single journey ticket costs ₩100 more than the equivalent transportation-card base fare.
6 Mistakes First-Time Riders Should Avoid
- Entering before confirming the direction. The correct line can still have two opposite platforms.
- Using a different transportation card when exiting. Use the same card you tapped at entry.
- Following an exit sign too early during a transfer. Follow the next line sign, not the station exit.
- Ignoring the exit number. Large stations can put exits far apart.
- Buying single journey tickets for every ride when you plan to travel all day. A transportation card is usually easier.
- Assuming every transfer is short. Major transfer stations can involve long underground walks.
