Check whether a TikTok username is available, see exactly which rules it breaks, and get brandable alternatives when it's already taken.

Grabbing the same handle everywhere? Instagram, YouTube, X (Twitter) · all free tools
Type a handle above and this tool validates it against TikTok's actual username rules, so you find out immediately if it's too long, uses a character TikTok rejects, or ends in a period. That check is instant and always works.
It then attempts a live lookup of the public profile. Worth knowing up front: TikTok frequently serves a bot challenge to automated requests rather than the real page. When that happens the tool says it couldn't confirm and gives you a one-click verification link, instead of guessing. Telling you a handle is free when it isn't would be the worst possible failure for a tool like this.
When a handle is gone, or can't be confirmed, you get a list of alternatives that still read like a real brand rather than a string of random numbers. Click any suggestion to check it without retyping.
Type the username you want, with or without the @. The tool strips the @ and checks the rest against TikTok's rules as you type.
Before any lookup happens, you'll see whether the handle is the right length and uses only letters, numbers, underscores and periods.
The lookup reads the public TikTok profile URL for that handle and reports available, taken, or couldn't confirm.
Open the verification link to confirm on TikTok itself, then claim the handle in the app. Good handles disappear fast.
TikTok handles can be up to 24 characters long and may contain letters, numbers, underscores and periods. Spaces, hyphens, emoji and other symbols are rejected. A handle also can't end with a period, which is the rule that trips up most people trying to use a name like "studio." or "daily.".
Handles are not case sensitive. Typing YourBrand and yourbrand gets you the same profile, and TikTok displays the lowercase form. That means capitalisation is not a way around a name being taken, though you can still set your display name with capitals, spaces and emoji, since the display name is separate from the handle.
One more constraint people miss: TikTok limits how often you can change your username, typically to once every 30 days. Pick something you can live with, because you won't be able to iterate on it week to week.
The instinct is to bolt numbers onto the end. Resist it. A handle like yourbrand2847 signals a throwaway account, is impossible to say out loud, and gets misremembered every time someone tries to find you. If you're building something you intend to monetise, the handle is part of the brand.
Better patterns keep the name readable. Prefixes like the, real, its and go work well. Suffixes like hq, studio, media, daily, tv and co read as intentional rather than desperate. If the core word is short, adding a category word (yourbrandfinance, yourbrandfitness) both frees up the handle and tells a new visitor what the account is about.
There's also the option most people skip: change the core word. A handle that's memorable and available beats a handle that's your first choice with junk appended. The suggestion list above is built to only return handles that pass TikTok's rules, so anything you see there is at least claimable in principle.
If you're posting the same short-form content to TikTok, Instagram Reels and YouTube Shorts, a matching handle everywhere is worth real effort. It makes cross-promotion trivial, it makes you findable when someone remembers your name but not the platform, and it protects you from someone else taking your name on a platform you haven't launched on yet.
Check the handle on every platform before committing to it on any of them. It's common to find a name that's free on TikTok but long gone on Instagram, and discovering that after you've built an audience is an expensive mistake.
Rules differ more than people expect. X caps handles at 15 characters and allows only letters, numbers and underscores, so any name with a period in it is off the table there. YouTube requires at least three characters and at least one letter. A name that works everywhere has to satisfy the strictest platform on your list, which is usually X.
Short wins. Every extra character is another chance for someone to typo it, and handles get read aloud in videos, printed in bios, and typed from memory far more often than founders expect. Under twelve characters is a good target.
Say it out loud before you commit. If you have to spell it, or if it contains a word people routinely misspell, that friction compounds across every video you ever post. Periods and underscores are especially bad for this, since nobody hears them in speech.
For a faceless or niche channel, a descriptive handle does double duty. Something like dailystoicclips or aitoolsdaily tells a new viewer what they're subscribing to before they read a single word of your bio, and it surfaces in TikTok's search when people look for that topic rather than for you by name.
Avoid tying the handle to something you'll outgrow. Year numbers date instantly. A single platform's name in your handle (yourbrandtiktok) looks wrong the moment you cross-post to Reels and Shorts, which is exactly what most growing accounts end up doing.
