For those who have been using LINE for a long time but suddenly get asked, “ What's your LINE ID?” and can't remember or aren't sure where to check in the app, you can actually see your LINE ID easily through your profile page in just a few steps.
LINE ID is a unique identifier used for LINE users. Once you set a LINE ID, others can use it to search for and add you as a friend, even if they don't know your phone number.
LINE IDs are not automatically created when registering an account; you must set one yourself. However, you can still use LINE normally without an ID, though having one makes it easier for friends tofindyour LINE account.
Therefore, LINE ID is different from your profile name (or the display name shown in LINE). The profile name is what others see on your account, while the LINE ID is a code to identify you and can be used to search and add you as a friend.
If you can't remember your LINE ID, you can check it through the LINE app by following these steps:
Open the LINE app on your phone.
Select the “Home” tab.
Tap the “Settings” icon shaped like a gear.
Choose the “Profile” menu.
Look for the “LINE ID” section.
If you have set a LINE ID before, it will be displayed there.
You can also choosewhetherto allow others to add you by searching your LINE ID.
If after following these steps you find no LINE ID, don’t worry. LINE does not require every account to have one. Users can register and use LINE without setting an ID. You can set your LINE ID yourself.
Once you have set your LINE ID, you cannot change or delete it. Therefore, before deciding on your LINE ID, double-check the spelling and choose the name you want to use carefully to avoid mistakes or ending up with an unwanted ID later.
Also, be cautious about sharing your LINE ID in public spaces such as websites, social media, or posts accessible by everyone. This may allow strangers to find and add you easily and could expose you to scammers who might use your information to contact you with deceptive messages or cause annoyance.
