TikTok username rules: characters, changes and links

Characters are limited

A username can contain letters, numbers, underscores and periods. A period cannot be at the end.

One change every 30 days

TikTok says a username can be changed once every 30 days. Decide before you change, because the old link stops pointing to your profile.

Giving up a username

TikTok says that if you give up a username, you cannot add it to an account for a short period. It does not publish how long.

Deleting an account

TikTok says a deleted account is deactivated for 30 days and then erased permanently. See what happens after deletion.

A taken username is a different question

See the TikTok claim page for the routes TikTok publishes.
