In Korea, a surprising amount of daily life runs through apps that most people outside the country have never heard of. Directions come from Naver rather than Google. Group projects are organised on KakaoTalk rather than WhatsApp. Dinner arrives through Baemin, and parcels through Coupang. Arriving without these apps is like arriving without a map, and sometimes that’s literally the problem.
The harder question isn’t which apps, though, but when each one will let you in. Korean apps ask for different things before you can use them, and in your first weeks you may not have all of them yet. This guide sorts the essentials by when you can realistically set them up. For where this fits in your first month, see Your First 30 Days in Korea.
The short answer
- Install before you fly: Naver Map (or Kakao Map), Papago, KakaoTalk.
- Worth trying in your first weeks: k.ride for taxis, which accepts overseas cards, and Baemin for delivery, which has English and accepts overseas cards. Check what its sign-up asks of you.
- After your Residence Card arrives and 본인인증 works: your bank’s app, a payment app (Toss, Kakao Pay, or Naver Pay), Coupang, and extra features in many other services.
- On campus: your university’s own app or portal, its learning-management system, and usually Everytime.
Four different things an app may ask for
Most app frustration in your first weeks comes from not knowing which of these an app actually needs. They’re separate, and having one doesn’t mean you have the others:
| Requirement | What it means |
|---|---|
| A Korean phone number | owning a Korean number at all, prepaid or contract |
| Text-message verification | receiving a sign-up code on that number |
| 본인인증 (identity verification) | the app confirming your identity through the personal details your carrier holds for you |
| A supported payment method | a card, account, or payment service that particular app accepts |
A prepaid SIM can give you a number and text codes without supporting 본인인증. An overseas card may be accepted for payment by an app whose sign-up still needs a Korean number. And 본인인증 generally works only once your phone line is registered with details that match your Residence Card. So when an app refuses you, work out which of the four it wants before giving up on it.
Before you fly
Naver Map (네이버 지도) or Kakao Map (카카오맵): directions. Google Maps has long offered limited walking and driving directions in Korea, a consequence of restrictions on exporting detailed map data. Google received a conditional approval in February 2026, but approval isn’t the same as new features in the app, so check how it performs on the routes you actually need. For now, most residents use Naver Map or Kakao Map for walking routes, bus and subway connections with live arrival times, and searching for places. Naver Map has an English setting, though some labels stay in Korean. Install one before you land, and save your housing address in it.
Papago (파파고): translation. Naver’s translator is strong on Korean. Use its camera mode for menus, notices, the Korean text beside the care symbols on clothing labels, and the paperwork in your mailbox. It can’t replace a human for contracts or immigration documents, but it handles daily life well.
KakaoTalk (카카오톡): messaging. This is the closest thing Korea has to a national messaging system. Class group chats, lab announcements, landlords, part-time employers, and new friends will all expect it. You can usually start with your existing phone number. Some features, such as Kakao Pay and gift-giving, need Korean verification later.
When you get a Korean number, keep your existing account rather than starting a new one:
- Before you change numbers, check that your account’s recovery details (such as your email) are up to date.
- Change the number inside the app, in your account settings, so the account moves to your new number.
- Backing up your chats is a separate step. If you’re also changing phones or reinstalling the app, follow KakaoTalk’s chat-backup instructions first.
Your first weeks: before your Residence Card arrives
These are worth setting up while your card and phone line are still in progress.
Getting around
- T-money card: a physical card rather than an app, sold at convenience stores and topped up with cash. It’s the simplest way to ride buses and subways before you have a Korean bank account.
- k.ride: Kakao Mobility’s taxi app for foreign visitors. It runs in English, Chinese, and Japanese, accepts registered overseas credit cards, and has built-in translation for talking to the driver.
- Kakao Metro, or your map app’s subway view: platforms, transfers, and last-train times.
Eating
- Baemin (배달의민족): Korea’s largest food-delivery app. Since February 2026 it has offered an English, Chinese, and Japanese interface for food delivery and accepts overseas cards and global payment services such as Alipay+ and WeChat Pay. Payment, in other words, needn’t be the obstacle. Sign-up and phone verification may still ask for a Korean number, and you’ll need to enter a Korean delivery address, so check those steps when you install it.
- Coupang Eats and Yogiyo: the main alternatives. Requirements differ by app and change often, so check each one.
Staying oriented
- Your university’s app or portal, plus the international office’s KakaoTalk channel if it has one. Orientation schedules, course registration (수강신청) notices, and dormitory updates often appear there first.
After your Residence Card arrives and 본인인증 works
Once your card has arrived and your phone line is registered with matching details, a second layer opens up.
Money
- Your bank’s app. Open the account at the branch, then register internet and mobile banking at the counter, where staff can help. That’s far easier than doing it alone in Korean later. If your account starts as a transaction-limited account, the app will show the same limits. See How to Open a Bank Account in Korea.
- A payment app: Toss (토스), Kakao Pay (카카오페이), or Naver Pay (네이버페이). These handle transfers to friends, splitting bills, online checkout, and sometimes in-store payment. You don’t need all three. Pick the one your friends and the shops you use accept most.
Shopping
- Coupang (쿠팡): Korea’s dominant online store, known for next-day and often early-morning delivery. Sign-up and payment generally go most smoothly with a Korean phone number and a Korean card. Its “Rocket” delivery makes it the default for bedding, kitchen basics, and anything you forgot to pack.
- Karrot / 당근 (Danggeun): the neighbourhood second-hand marketplace. It’s ideal for furnishing a room cheaply, and for selling everything when you leave. It verifies your neighbourhood by location, and buying usually means meeting the seller nearby. Meet in a public place and check the item before paying.
Taxis
- Kakao T (카카오 T): the main domestic taxi app. It’s easier to use than k.ride once you have a Korean number and card registered.
Government and ID
- Mobile Residence Card (모바일 외국인등록증), issued through the government’s Mobile ID app. Installing the app isn’t enough on its own; there’s a separate issuance step. If your Residence Card has an IC chip, you can generally issue the mobile version by tapping the card to your phone. If you hold an older card without a chip, you’ll generally need to visit an immigration office and complete issuance by QR code. Some banks and services accept the mobile card, but support varies, so carry the physical card too. See the ARC guide and the official Mobile ID site.
- Hi Korea (hikorea.go.kr): immigration reservations, extensions, and change-of-address reports. It works best in a browser. Bookmark it.
On campus
- Your university’s official app and portal: grades, notices, student ID, and often dormitory and library services.
- The learning-management system (LMS): where assignments, readings, and recorded lectures live. Your professors will tell you which one, and you’ll check it every week.
- Everytime (에브리타임): a student community app used at most Korean universities, with timetables, course reviews, and anonymous boards. It requires student verification. It’s mostly in Korean, but the timetable and course reviews are useful even with a translator, especially before course registration. Read the anonymous boards with the usual caution.
Housing apps, briefly
Korean property apps such as Zigbang (직방) and Dabang (다방) list one-rooms and officetels with photos, prices, and maps. They’re mostly in Korean and lead you to agents who may not speak English. Use them to get a sense of prices in an area, not as a substitute for seeing the room or checking the contract. Before you use them, read Dormitory vs Goshiwon vs One-Room vs Share House.

Requirements as of October 2026. Apps change their sign-up rules often, so check the current requirements in each app. Download apps only from the official app stores, and check the developer name.
When an app won’t let you in
- Work out which requirement failed: the number, the text code, 본인인증, or payment. The fix is different for each.
- 본인인증 fails. First check the details registered with your carrier, including how your name is recorded there, and ask the carrier to correct anything that doesn’t match your Residence Card. If the carrier’s records are right and it still fails, contact that app’s customer support.
- It wants a Korean number you don’t have yet. Use the visitor-friendly options above until your line is set up.
- It won’t accept your card. Foreign cards are hit and miss with Korean payment systems. A Korean debit card (체크카드) from your bank, or a payment app linked to your Korean account, usually solves it.
- Everything is in Korean. Papago’s camera translation works on app screens too. Take a screenshot and translate it.
FAQ
Do I need to stop using Google Maps? No, but before relying on it, check it on the routes you actually use. Most students make Naver Map or Kakao Map their main app.
Which payment app should I choose? Whichever your friends and the shops you use accept most. See above.
Can I use Korean apps in English? More of them than a few years ago: Naver Map, Baemin, and k.ride all have English options. Many others are still Korean-only, which is what Papago’s camera mode is for.
Is it safe to link my bank account to these apps? The major ones are mainstream services used by millions of Koreans. The usual precautions apply: download only from the official app stores, never share verification codes, and be suspicious of messages asking you to “verify” your account through a link.
Your phone will be the most-used tool of your first semester. Set it up in stages, and don’t take it personally when an app says no in week one. If an app saved you here and isn’t on this list, tell me and I’ll look at it for the next update.
