Your LINE ID is a unique key that lets other users find you on LINE. Your LINE ID isn't set when you sign up for a LINE account, so you need to set it yourself.
Setting a LINE ID is optional, and you can still use LINE without one. Setting a LINE ID makes it easier to add friends. You can search for someone else's ID, or exchange IDs to add each other even if you don't know their phone number.
Be advised
As stated in our Terms of Use, making your LINE ID public on the internet for the purpose of meeting other people is not allowed. Please refrain from such activity.
Setting a LINE ID
Be advised
- LINE IDs can only contain lowercase half-width alphanumeric characters, periods (.), hyphens (-), and underscores (_).
- Once you set a LINE ID, it cannot be changed or deleted.
1. From the Home tab, tap Settings > Profile > ID or LINE ID.
Note:Tap here to go to your profile settings from your smartphone.
2. Enter your preferred ID and tap Check.
3. If you see the "This ID is available" message, tap Save or Use.
If you see a message saying "This ID is unavailable" in step 3, it means that someone is already using that ID. In this case, please register a different ID.
If you see a different error message, or if the LINE ID field doesn't change and remains blank, your device information may not be synced with the information on LINE's servers. In that case, try syncing your profile and settings data. Changing your LINE ID
Once a LINE ID is set, it cannot be changed.
If you want to change your current LINE ID, you need to delete the LINE account first. You can set a new LINE ID after creating a new LINE account.
Note: When you delete your account, all data, including purchased items, your registered phone number, friends and groups, chat history, and registration with other authorized apps (e.g. LINE Games, LINE PLAY), is deleted. Checking and sharing your LINE ID
To check your LINE ID:
1. From the Home tab, tap Settings > Profile.
Note:Tap here to go to the LINE ID screen from your smartphone.
2. Check what LINE ID is displayed in the ID or LINE ID field.
If you want to copy and share your LINE ID, tap Copy to the right of it. You can paste the copied LINE ID by tapping a message text box, note, or other place to enter text > Paste. Preventing others from searching for your LINE ID
1. From the Home tab, tap Settings > Profile.
Note:Tap here to go to your profile settings from your smartphone.
2. Turn Allow others to add me by ID OFF.
