KakaoTalk in Korea: why new teachers need it in week one
KakaoTalk is Korea's default messaging app. Your school, your co-teachers, your landlord and many shops will reach you there, not by text or WhatsApp. Install it before you fly with your home number, then switch to your Korean number once you have one.

Ask a Korean colleague for their number and they'll often give you their KakaoTalk ID instead. That tells you most of what you need to know.
Why it matters from day one
- Work. Most hagwons run staff group chats on KakaoTalk: schedules, cover requests, notices about parents and events. If you're not in the chat, you miss things.
- Daily life. Landlords, delivery drivers, clinics and hair salons often send KakaoTalk messages rather than texts.
- One account, several apps. The same Kakao account signs you in to Kakao T for taxis and KakaoMap.
Setting it up
- Install it before you fly and register with your home number, so you land already reachable.
- Switch to your Korean number later. When you get a Korean phone line, change the number in the app's settings. Your account and chats stay.
- Use the name your school knows you by on your profile, so your co-teachers can find you in the group.
Simple authentication, later on
Korean websites often ask you to confirm who you are. Once you have your Residence Card and a phone line in your own name, apps like Kakao, Naver and PASS can do that for you in a couple of taps. Not every service accepts every app for foreign residents yet, so if one fails, try another.
What people get wrong
- Waiting until arrival to install it. Your first message from the school may arrive before your first Korean SIM.
- Trying to run school chat on WhatsApp. Fine with one friend. The staff group will still be on KakaoTalk.
Your school will add you to its group once you're hired. If you're still looking, browse our job board or register with Park English and we'll match you with a school.
