How to change your TikTok username, step by step
Username changes happen inside the TikTok mobile app, on the Edit profile screen. The whole process takes under a minute once you have a new name in mind.
- Open TikTok and tap Profile in the bottom-right corner.
- Tap Edit profile.
- Tap Username.
- Delete the old username and type your new one.TikTok shows a green check if it is available and valid, or a message if it is taken or breaks a rule.
- Tap Save (or Confirm) to apply the change.
TikTok username rules
Before you pick a name, know the constraints so the save does not fail. A TikTok username must be 2–24 characters and can contain only lowercase letters, numbers, underscores, and periods — and it cannot end in a period. It also has to be unique, so a name another account already uses is not available.
TikTok shows your username in lowercase, and it is the handle people use to @mention you and to find you in search, so legibility matters. If a green check appears next to the field, the name is valid and free; if you see a warning, the name is either taken, too short or long, or uses a character that is not allowed. Because you are committing to the name for at least 30 days, it is worth getting it right rather than saving the first thing that fits.
How often can you change it?
You can change your TikTok username only once every 30 days. If you try again before 30 days have passed, TikTok shows an error and blocks the change — there is no exception, including for verified accounts. Note that your nickname (the display name shown above your handle) is separate and can be changed more often, roughly once every 7 days, so if you only want a cosmetic change, edit the nickname instead.
What changes when you rename
Your username is part of your profile URL (tiktok.com/@yourname), so changing it changes that link. Any place you have shared the old link — your Instagram bio, a website, a YouTube description — will need updating, or it will break. Your followers, videos, and likes all stay with the account; only the handle and link change. If you give up a username, TikTok locks it for a short period before anyone else can take it.
It is worth doing a quick sweep after the change: update your link-in-bio, your other social profiles, any business cards or email signatures, and anywhere creators have tagged your old handle. The change itself is instant, but the cleanup is what keeps people from hitting a dead link when they look for you.
How to choose a TikTok username worth keeping
Because TikTok limits you to one change per 30 days, treat this like a decision you will live with, not an experiment. The strongest handles are short, easy to say out loud, and free of stray numbers or doubled-up periods that are hard to remember. If you are building a brand or a creator presence, the single most useful thing you can do is pick a name that is also available on the other platforms your audience uses — Instagram, YouTube, a website domain — so people find the same you everywhere. Checking that before you commit saves you from claiming a TikTok handle you cannot match elsewhere.
