What are Instagram's username rules?

Up to 30 characters, using only letters, numbers, periods and underscores. No spaces, no two periods in a row, and it cannot start or end with a period. Instagram stores every username in lower case. Each name this tool shows is checked against those rules before you see it.

What are TikTok's username rules?

Up to 24 characters, using letters, numbers, underscores and periods, and it cannot end with a period. You can change your TikTok username once every 30 days, so it is worth picking one you can keep.

Should my username match on every app?

Yes, if you can get it. The same handle on Instagram, TikTok and YouTube means a viewer who finds you on one app can find you on the others by typing what they remember. Keep it under 24 characters with no hyphens, no two periods in a row and no period or underscore at either end, and the same name is valid on all three.

Can I use a fancy font in my username?

No. Usernames only accept plain letters, numbers and a few symbols. Fancy fonts work in your display name and bio instead; the font generator turns any text into bold, cursive or aesthetic letters you can paste there.

Is the username generator free?

Yes, with no login. It allows 15 generations an hour per person, so you can try every style and platform.

A username is typed from memory

Someone sees your video, wants more, and types your name into search. Every underscore they forget, every swapped letter and every birth year at the end is a chance to land on somebody else. That is why the names here avoid number padding and creative spelling.

Short and sayable wins. If you can tell someone your username out loud once and they find you, it works. If you have to spell it, it is costing you followers every time it is mentioned in a video or a comment.

Then match it everywhere you post. Pick the name, check it on each app, and use the same one. Your display name and bio can carry the personality; the username only has to be findable.

Frequently asked questions

Everything about choosing a username

Generate a list here, then tap the arrow next to a name: it opens that profile address on Instagram, TikTok or YouTube. A page that does not exist means the name is very likely free. Instagram and TikTok also tell you straight away in the Edit profile screen, so try your top three there before you settle.
