LINE

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, and you can use LINE without setting one.

Setting a LINE ID lets others search for you and add you as a friend even if they don't know your phone number.
Note:
- In Japan, you must be at least 18 years of age and have completed age verification on your main device.
- For more information about age verification, see About age verification. (only available in Japanese.)

Setting a LINE ID:
To set your LINE ID, follow the steps below. 1. Tap Settings > Profile > LINE ID.
2. Enter your preferred ID and tap Check.
3. If you see the "This ID is available" message, tap Use.
Note: 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 an 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. Please try repairing your profile and settings data from the main device you use LINE on.


Checking/sharing your LINE ID:
To check your LINE ID, follow the steps below. 1. Tap Settings > 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.

Also, you cannot check the LINE IDs of friends or acquaintances. If you want to know someone's LINE ID, have them share it with you using one of the above methods.
