Important: If you are using LINE in a country or region outside of Hong Kong, Japan, Korea, Taiwan, or Thailand, the phone number-related information in this Help article only applies to LINE accounts created with LINE versions earlier than 13.11.0.
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.
Useful info (for users in Japan)
To protect minors who are using the service, LINE has in cooperation with various mobile service providers partially restricted some features, such as setting a LINE ID, searching for IDs, and searching for friends using their phone numbers for users under 18. To verify your age and gain full functionality, see About age verification and verify your age on the smartphone version of LINE.
Note: The Help article above is only available in Japanese.
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. Tap > Profile > LINE ID.
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 is deleted, including purchased items, your registered phone number, friends and groups, chat history, and registration with other authorized apps such as LINE Games. Checking and sharing your LINE ID
1. Tap > Profile.
2. Check what LINE ID is displayed in the 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
Be advised
Please do the following steps on the smartphone version of LINE.
