LINE Official Account

A LINE Official Account is the business identity that every LINE ad is served from and reports back to.

You create the Official Account first, then link it to Ads Manager. It holds your friends, your broadcast messages, your one-to-one chat, and the LINE Tag you use for tracking. Paid ads and organic messaging both run through this same account, so acquisition and follow-up sit in one place.

A dental clinic runs a Gain Friends campaign, and each new friend lands in the same Official Account it later uses to broadcast appointment reminders and promotions.

The account is the asset, not the ad. People pour budget into acquisition and then never message the friends they paid for, so the follow-up revenue that justifies LINE in the first place never shows up.

The ad buys the friend; the account keeps them.
