How to Use KakaoTalk in Korea: A Complete Guide for Foreigners
If you're traveling to Korea or planning to live here for a while, there is one app you'll probably hear about almost immediately: KakaoTalk.
In Korea, KakaoTalk is much more than a messaging app. People use it to stay in touch with friends and family, communicate with coworkers and classmates, contact businesses, receive reservation updates, ask questions, share locations, and join group chats.
For international visitors, KakaoTalk can be especially useful if making phone calls in Korean feels intimidating. Instead of calling a restaurant, hotel, clinic, or other business, you may be able to send a message and communicate at your own pace.
Kakao also introduces KakaoTalk as a useful tool for travelers in Korea, including features such as messaging, Open Chat, voice calls, video calls, and communication with businesses.
If you have never used KakaoTalk before, the setup process and some of its features may feel unfamiliar at first. This guide walks you through how to install KakaoTalk, create an account, add friends, send messages, use KakaoTalk Channels and Open Chat, and keep your account secure while traveling or living in Korea.
1. How to Install and Set Up KakaoTalk
KakaoTalk is available for both Android and iPhone. Android users can download it from Google Play, while iPhone users can find it in the App Store by searching for KakaoTalk.
How to Sign Up for KakaoTalk
The basic setup process is fairly straightforward.
- Download and install the KakaoTalk app on your smartphone.
- Open the app and review the terms of service.
- Enter the mobile phone number you want to use.
- Enter the verification code sent to you by SMS.
- Create a display name or nickname for your profile.
- Create or connect a Kakao Account if needed.
KakaoTalk uses SMS verification during the registration process. Your verification code should be treated like a password, so never share it with anyone, even if they claim to be helping you set up your account.
Can You Use KakaoTalk Without a Korean Phone Number?
In many cases, KakaoTalk can also be used with an overseas mobile number. Kakao's official safety information includes guidance for users registered with overseas mobile carriers, so having a Korean number is not necessarily required just to use basic KakaoTalk messaging features.
However, there is an important distinction to understand.
- Using KakaoTalk for messaging, friends, and chats
- Using Korean identity verification and certain connected services
These are not always the same thing.
Some Kakao services and other Korean online services require identity verification connected to a Korean mobile phone number. Certain verification features may therefore be unavailable or more limited if you only have an overseas number.
If you are visiting Korea for a short trip, using KakaoTalk with your existing international phone number may be enough for your needs.
If you're staying in Korea long term, however, having a Korean mobile number registered in your own name can make it much easier to use various local services and verification systems.

2. How to Add Friends and Send Messages
Once KakaoTalk is set up, the next step is adding people to your friend list. In Korea, people commonly connect through phone numbers, KakaoTalk IDs, or QR codes.
Adding Friends by Phone Number
If you allow KakaoTalk to access your phone contacts and enable the relevant friend settings, people saved in your phone's address book may appear in your KakaoTalk friend list.
However, knowing someone's phone number does not always mean you will automatically be able to add them.
KakaoTalk allows users to control whether other people can add them as friends using their phone number. This setting can be managed under the Friends section of the app.
So if you save someone's number but they do not appear in KakaoTalk, it does not necessarily mean you entered the number incorrectly. Their privacy settings may simply prevent phone-number-based friend requests.
Using a QR Code
If you would rather not share your phone number, exchanging KakaoTalk QR codes is one of the easiest options.
Open the Add Friends menu in KakaoTalk and either show your own QR code or scan someone else's code.
This can be particularly convenient when meeting someone while traveling, joining a local activity, communicating with guesthouse staff, or exchanging contact information with new friends in Korea.
The exact location of the QR code menu can change slightly depending on your phone and app version, so look for the QR code icon in the friend-addition section if the interface looks different.
Sending Messages
Once someone is on your friend list, KakaoTalk works much like other popular messaging apps.
You can use it to:
- Send text messages
- Share photos and videos
- Send files
- Share locations
- Use stickers and Kakao emoticons
- Create group chats
- Make voice calls
- Make video calls
If you are not confident speaking Korean, messaging can actually be easier than making a phone call. It gives you time to translate a sentence, check what the other person wrote, and make sure important information such as addresses, reservation times, and directions is recorded in the chat.
3. Useful KakaoTalk Features for Traveling and Living in Korea
KakaoTalk may look like a simple messenger at first, but in Korea it is connected to many aspects of everyday life.
Two features that international visitors may find particularly useful are KakaoTalk Channels and Open Chat.
KakaoTalk Channels
A KakaoTalk Channel is similar to an official business account. Restaurants, hotels, clinics, beauty salons, shops, online stores, brands, and other organizations can operate their own channels.
Depending on the business, adding its KakaoTalk Channel may allow you to:
- Check store or business information
- Receive announcements and promotional updates
- Get coupons
- Send one-on-one inquiries
- Ask about reservations
- Receive order or delivery information
Some verified business channels may also display an official verification indicator, which can help users identify legitimate accounts.
For travelers who are uncomfortable making phone calls in Korean, this can be particularly helpful.
For example, you might send a short message such as:
- “Can I make a reservation for tonight?”
- “Do you have an English menu?”
- “Is parking available?”
- “I'd like to change my reservation time.”
Keep in mind that not every restaurant or business offers customer service through KakaoTalk. If you cannot find a channel or chat option, check the business listing on Naver Map, KakaoMap, or the company's official website for other contact methods.
Open Chat
KakaoTalk Open Chat lets people join conversations based on shared interests without having to be regular KakaoTalk friends first.
You may find Open Chat rooms related to topics such as:
- Travel in Korea
- Life in Korea
- Language exchange
- Local communities
- Hobbies
- Study groups
- Events and activities
Kakao also introduces Open Chat as one way travelers can connect with locals and other visitors and exchange useful information.
However, remember that Open Chat may involve people you have never met before. Treat it like any other public or semi-public online community and avoid sharing sensitive personal information.
- Do not send photos of your passport.
- Do not share credit card or bank information.
- Never give anyone your SMS verification code.
- Be cautious with payment links sent by strangers.
- Be skeptical of unusually attractive investment or job offers.
4. KakaoTalk Tips Foreign Visitors Should Know
Update Your Phone Number If It Changes
Some visitors initially use KakaoTalk with an overseas phone number and later switch to a Korean SIM or mobile plan.
The opposite can also happen: someone living in Korea may return home and stop using their Korean number.
If your phone number changes, check the phone number registered with KakaoTalk and update your account information when necessary.
Before changing numbers or phones, it is also a good idea to make sure you know the email address and password connected to your Kakao Account. This can make account recovery much easier if you reinstall the app or switch devices.
Avoid Adding Too Many People at Once
If you have just created a new KakaoTalk account, avoid adding a very large number of friends or creating many chat rooms within a short period.
Kakao operates automated systems designed to detect unusual or potentially abusive activity. Behaviors such as rapidly adding many users, repeatedly creating chat rooms, or using unreliable virtual overseas phone numbers may sometimes trigger temporary protection measures.
Depending on the situation, certain features such as adding friends, creating new chats, using Open Chat, making free calls, or using KakaoTalk on a PC may be temporarily restricted.
Most ordinary travelers do not need to worry about this. Simply use the app normally and avoid unusually high levels of activity immediately after creating a new account.
Turn Off Notifications for Busy Group Chats
If you study, work, or live in Korea, you may eventually find yourself in several KakaoTalk group chats.
Some can become very active.
Fortunately, you can mute notifications for individual chat rooms without leaving them. This is useful when you still need to check announcements or updates but do not want your phone buzzing throughout the day.
KakaoTalk Is Also Available on PC
If you spend a lot of time studying or working on a computer, KakaoTalk's desktop version can be very convenient.
Instead of constantly checking your phone, you can read and reply to messages directly from your computer.
When connecting your Kakao Account to another device such as a PC or Mac, Kakao may require additional security verification. Treat any verification code you receive as sensitive information and never share it with another person.
5. How to Use KakaoTalk Safely
KakaoTalk is convenient and widely used, but its popularity also means scammers may try to use it for phishing or account theft.
Never Share Your Verification Code
This is one of the most important rules to remember.
Never give anyone your SMS verification code or Kakao Account password.
Be especially careful if someone claiming to be a friend, acquaintance, employee, or customer service representative suddenly asks you to:
- Send them a verification code
- Transfer money urgently
- Buy gift cards on their behalf
- Log in through an unfamiliar website
- Send banking or credit card information
If a message seems unusual, contact the person through another method before doing anything.
Enable Two-Step Verification
If you plan to keep using your Kakao Account, enabling two-step verification can provide an extra layer of security.
You can check the available security options under Settings → Kakao Account → Two-Step Verification.
With two-step verification enabled, knowing your password alone may not be enough for someone else to access your account.
Control Who Can Add You by Phone Number
If you are uncomfortable with people being able to add you simply because they know your phone number, check your friend privacy settings.
In KakaoTalk, you can manage the option under Settings → Friends → Allow Adding Friends by Phone Number.
Turning this setting off can give you more control over who appears on your friend list.
KakaoTalk FAQ
Q1. Can I Use KakaoTalk Without a Korean Phone Number?
Yes, basic KakaoTalk use may be possible with an overseas mobile number. Kakao provides information for users of overseas mobile carriers as well.
However, using KakaoTalk as a messenger and completing Korean mobile identity verification are two different things. Some verification features and services connected to Korean websites or apps may require a Korean mobile number registered under your identity.
For a short trip, an international number may be perfectly adequate. For long-term life in Korea, having your own Korean phone number is generally more convenient.
Q2. Can I Contact Korean Restaurants or Businesses Through KakaoTalk?
Yes, if the business operates a KakaoTalk Channel or offers one-on-one chat support.
Depending on the business, you may be able to ask questions, check reservation information, receive coupons, or get updates about orders and deliveries.
However, KakaoTalk customer support is not available at every business, so always check the company's official contact information first.
Q3. Are KakaoTalk Messages and Calls Free?
KakaoTalk messaging, voice calls, and video calls use an internet connection rather than traditional international calling.
The KakaoTalk service itself does not charge a separate fee for sending ordinary messages or making KakaoTalk voice and video calls.
However, mobile data charges may still apply depending on your carrier and mobile plan. This is especially important if you are using international roaming.
Whenever possible, using Wi-Fi can help you avoid unnecessary roaming data charges while traveling in Korea.
Final Thoughts
KakaoTalk is much more than a messaging app in Korea. It is part of everyday communication and can be useful for everything from talking with friends to joining group chats, contacting businesses, receiving reservation information, and finding local communities.
If you are visiting Korea for the first time, you do not need to learn every KakaoTalk feature immediately. Start with the basics: install the app, set up your account, learn how to add friends, and become comfortable sending messages.
If you do not want to share your phone number with someone you just met, exchanging QR codes can be a convenient alternative. And when you need to contact a restaurant, hotel, or other business, check whether it has an official KakaoTalk Channel.
If you plan to live in Korea long term, managing your Kakao Account and Korean phone number carefully becomes more important. Keep your account information up to date, use two-step verification when possible, and never share passwords or SMS verification codes.
KakaoTalk may feel unfamiliar at first, but once you learn the basic features, it can make traveling and everyday life in Korea much easier.
