What should I do if I changed my KakaoTalk admin account phone number?

To prevent other people from using your Kakao Account, you must provide your previously verified phone number when logging into KakaoTalk from a device with a phone number that is different than the one associated with your Kakao Account.

Enter the phone number you previously verified for KakaoTalk. Note the following:

• If KakaoTalk is still installed on your previous device, you can find the previously verified phone number by navigating to Kakao Talk > More > Edit Profile.
• To protect your Kakao Account, you may attempt to enter your previous phone number up to five times. After five incorrect attempts, you will have to try again later.
