Difference between accounts and IDs

A LINE account is defined as the phone number, name, photo, ID, and other information used on LINE. By deleting your account, all of the aforementioned information will be deleted.

An ID is a key used to identify LINE users. This is not configured by default when you first start using the service. You can configure one by going to the Home tab > Settings > Edit profile.

Important: LINE IDs cannot be changed once configured.

With a LINE ID, users who do not know your phone number can easily find and add you as a friend if you exchange IDs with them. If you do not want other users to find you using your ID, you can turn off Allow others to add me by ID under Edit profile.

Note: Publicizing LINE IDs on the internet for the purpose of meeting a person for sexual encounters is prohibited by our Terms and Conditions of Use.

I can't set the LINE ID I want to use

If you see the message "This ID is already in use" when trying to set your ID, or if another user shows up when you search the ID you want to use in Add Friends, it means that another user has already taken that ID.

As LINE does not allow duplicates of the same ID, please try setting a different one.
