LINE Users Must Add Phone Numbers by Year-End or Risk Losing Their Accounts

LINE users in Taiwan are being urged to check their account settings before the end of the year. The company says accounts linked only to Facebook and lacking a registered phone number will be deleted after 11:59 p.m. on December 31, 2026.

Deletion would mean more than losing Facebook login access. Stickers, coins, purchased items and important chat records stored in the account could also become unavailable and unrecoverable.

LINE said the phone-number requirement aims to strengthen account security and reduce fake-account and fraud risks. Users who registered or logged in through Facebook in the past are especially encouraged to check whether their accounts have a phone number attached.

The check can be completed in the LINE app by opening Home, Settings and My Account, then reviewing the phone-number field. If it is blank, users can enter a number and complete verification without using a separate website.

LINE also recommends setting an email address and password, and linking at least one Apple or Google account. It warns that every phone number must be unique to one LINE account. Reusing a number, email address or linked account already assigned elsewhere could disconnect the original account’s association and potentially prevent it from working.
