Please Note the Elderly and Pregnant Reserved Seats in the Korean Subway


Elderly Reserved Seats:
At both ends of each subway car in Korea, there are about six seats reserved for elderly passengers or those with mobility issues. These seats are typically dark-colored.
Pregnant Reserved Seats:
Pregnant reserved seats are located in the same row as regular seats and are differentiated by pink cushions. These seats are specifically for women in the early stages of pregnancy.
In Korea, you will often see people standing rather than sitting in these reserved seats. Koreans will actively give up their elderly and pregnant reserved seats for those in need.
Foreigners, be sure to pay attention when riding the subway!!!
Subway Signboards: Master the Most Direct Arrival Information
In-car Signboards
Each subway car is equipped with an electronic signboard,
allowing you to check the station name and the direction to disembark at any time.


Station Signboards
In addition to the in-car signboards, each subway station also has signboards displaying the current station name, usually with both English and Chinese.



Transfer Information Signboards
Inside the subway stations, there are also transfer information signboards,
which display numbers in different colors, the station names you can reach, and directional arrows.
Different colored numbers represent different subway lines,
for example: Blue 1 represents Line 1
Purple 5 represents Line 5
Yellow 3 represents Line 3


By following the numbers corresponding to the subway lines you need to transfer to and the arrows next to the numbers, you can easily find the location to transfer to the new subway line.
Subway Exit Signboards
Subway exit signboards are marked with a prominent yellow color
and feature both "EXIT/出口" in English and Chinese.
The numbers on the subway exit signboards indicate the exit number,
helping you quickly locate the corresponding exit.


Pay close attention to the signboard information to avoid missing your destination.
Emergency Exit at Ticket Gates
The following two situations are likely to require using the emergency exit at the subway ticket gates:
- Entering the wrong ticket gate: Even locals familiar with the route might accidentally enter the wrong direction at the ticket gate. If you enter the wrong gate, you need to exit the gate and re-enter from the opposite direction gate.
- Urgent need to use the restroom: Restrooms are located outside the ticket gates in the subway station. If you've already entered the ticket gate and suddenly need to use the restroom, you will need to exit the gate and then use the restroom.
Alternatively, if you need assistance from the subway staff, look for the emergency exit shown in the image below.

Then, press the green help button.
At this point, a staff member will proactively contact you through the help exit microphone.
Inform the staff that you need the door to be opened or other assistance (simple English: "Help please." / "Open the door please"), and the staff will open the door or provide help.
Luggage Storage Lockers at Subway Stations
Currently, most subway stations in Seoul have luggage storage lockers in various sizes, and the usage fees are quite reasonable (small luggage around 3,000 KRW/4 hours, large luggage around 5,500 KRW/4 hours, for reference). So, storing your shopping items or luggage that is inconvenient to carry while you explore will make your journey much easier!

Lost Items on the Subway
First, confirm the time you got off, the station, train number, and car number.
After getting off the subway, pay attention to the ground near the door, where you'll see a number like "5-2". This number corresponds to the car number.

Remembering the time of your ride and the car number will be very helpful when applying for lost and found. Contact the subway station’s lost and found center in a timely manner.
