Username availability checker

Stop ending up as name_123

It is a familiar story. You grab a great handle on Instagram, then go to sign up on TikTok and it is taken, so you add an underscore. On X it is gone too, so you add a number. A few apps later you have five slightly different usernames, and people can never find you. Checking every platform before you commit avoids all of that.

One handle everywhere

A matching username across platforms is easier to remember, easier to search for, and harder to impersonate. Creators, small businesses, and anyone building a personal brand benefit from being @samename on every app, so followers on one platform can find you on the others without guessing.

How the checker works

Enter one username and IdSnoop checks the public profile address for it on each platform at the same time. If a profile exists, the name is taken and you can open it to see who has it. If there is no profile, the name shows as available. The check takes a few seconds and does not create anything or contact any account.

Each platform has its own rules

Usernames are not allowed to be the same shape everywhere. X and Snapchat cap names at 15 characters, X needs at least 5, Snapchat names must start with a letter, and GitHub does not allow periods or underscores. The checker flags names a platform would reject, so you can pick one that works on all of them. A short name made of letters and numbers is the safest choice.

When your favourite name is taken

If the name you want is taken somewhere, try a short variation that still reads well, such as adding hq, the, or get, rather than a string of numbers. The checker suggests a few variations under your results, and you can check each one with a single click. Once you find a name that is free everywhere, claim it on every platform the same day.

Frequently asked questions

How do I check if a username is available on all social media?

Type the username above and IdSnoop checks Instagram, TikTok, Snapchat, X, YouTube, Pinterest, Twitch and GitHub at once, and shows whether it is available, taken, or not allowed on each one.

Is "available" a guarantee I can register the name?

It means no public account uses the name right now. Some platforms hold back names from deleted, banned, or reserved accounts, so the sign-up page has the final say. Claim the name soon after checking.

Why does a platform say "Not allowed"?

The name breaks that platform's username rules, for example it is too long for X or Snapchat, too short for X, or uses a character the platform does not allow.

Does checking a username tell anyone?

No. The checker only looks at public profile addresses. It does not sign up, message, or notify anyone.

Is the username availability checker free?

Yes. You can check usernames on IdSnoop for free, without an account.
