If there is a space in your Kakao Account email or password, the login button will not be activated (i.e. turn yellow).
Make sure there is no space in your Kakao Account email or password, and your password is at least 4 characters.
If your password includes special characters, change your keyboard setting to the default setting provided by your OS and try again.
Previous phone number is the phone number of the device used to log in with the Kakao Account recently.
To prevent other people from using your Kakao Account, you must provide your previous phone number if you want to log into Kakao Talk from a device different from the one whose number is associated with your Kakao Account.
Please enter the phone number you previously verified for KakaoTalk.
* If Kakao Talk is still installed on your previous device, you can find the previously verified phone number in Kakao Talk > More > Edit Profile.
* To protect your Kakao Account, you may attempt to enter your previous phone number up to 5 times. After 5 incorrect attempts, you will have to try again later.
You must remember your previous phone number because Kakao can't tell you.
If you don't remember your previous phone number, please check the instructions below and try again.
1. Is Kakao Talk still installed on your previous device?
Open Kakao Talk and you can find the previously verified phone number in More > Edit Profile.
2. Has your phone number changed?
If your phone number has changed, try to recall the previous phone number and enter that number. If you can't remember the number, ask your family or friends if they have your old phone number.
If that still doesn't work, contact your mobile service carrier or mobile phone agent.
3. Have you switched to a new phone or a new carrier?
When you switched to a new carrier, or re-subscribed to the mobile phone service with the same carrier, a temporary number may have been issued and changed without your knowledge. Contact your mobile service carrier or mobile phone dealer and ask if your phone number has been changed or if any temporary number has been issued.
4. Have you used a no-contract phone which had been owned by someone else, or have you logged in from a shared device?
It is possible that the device you used to log in may already have a Kakao Account with a different phone number. Please ask the previous owner of the device about the phone number.
5. Has your family or friend logged in with your Kakao Account?
If your family member or friend has logged in with your Kakao Account to access Kakao games or other services, try entering that person's phone number as the previous phone number.
(To protect your personal information, please do not log in using someone else's phone number or device.)

Someone with a malicious intent may try to compromise your Kakao Account by stealing your Kakao ID and password. Kakao has protection measures to prevent such account compromise.
If you get a message after changing a phone number, "The account is currently active under another phone number. Please do not use Kakao Talk on your previous device for 72 hours and try logging in again," and can't log in, please wait 72 hours and try logging in again.
If you keep experiencing login failure, check the status of your previous phone number (active, deactivated, etc) and contact our Customer Service.
If you get a message that the email address and password provided do not match even though you provided correct information, your Kakao Account email or password may have been saved inaccurately.
Click "Forgot your email address or password?" and try resetting your password by tapping on the link.
If you still get the same message after you have completed password reset and attempted to log in with a new password, it is possible that your account has been suspended. Please contact our Customer Service with your Kakao Account email, and we will be able to check the status of your account.
If the Kakao Account email and password do not match multiple times, login attempts can be restricted to protect the user.
For security reasons, Kakao do not provide the maximum number of attemtps or how long you have to wait. Please try again after some time based on the message appearing on the login screen.
