TikTok might remove verification without prior notice for various reasons. Some of these reasons include instances where the account has been transferred to a new owner, rendering the verification badge invalid. If the username associated with the account is changed, the account owner will need to reapply for verification.
Additionally, if there are changes in the account type, such as transitioning between a personal and business account, TikTok may remove the verification badge. It’s essential to be aware that TikTok holds the authority to remove verification in order to maintain the authenticity and integrity of the platform.
