Username availability checker
See whether a username is free on 98 sites before you commit to it. Wherever the name is taken, you see the account that holds it.
Reading the results
Taken
The site has an account with exactly this handle, and the result shows it. The check reads the profile rather than trusting that a page loaded, so a listed account is a real one.
Not found
The site answered that no such account exists. The name is very likely free there, but a site can still reserve it, hold it for a deleted account, or refuse it under its own rules.
No answer
The site was slow or refused the request this time. The summary says how many; search again in a few minutes, or check those by hand.
Picking a handle you can hold everywhere
The handles that travel furthest are short and plain. Every site accepts letters and numbers, but some reject dots, dashes or a leading digit, and length limits vary.
- Keep it to 15 characters.X allows no more than that, the tightest limit among the large networks.
- Use letters, numbers and underscores.Dots and dashes are refused on enough sites to split your name.
- Register soon after you check.Free names are taken every day, and a check only tells you about now.
- Look at who holds it.If one site’s copy belongs to an abandoned account, its support team may release it.

Questions
How do I check if a username is available?
Enter it above. Sites where an account already uses the handle show that account as a card; everywhere else, the name was not found and is very likely free.
Why check availability on 98 sites at once?
A handle is only useful as a brand if you can hold it everywhere you need it. Checking every site together shows straight away whether the name is clear or already split between strangers.
Can a username show as free and still be taken?
Yes. Some sites reserve names, hold handles from deleted accounts, or only show profiles to members. The check reports what each site shows the public.
Is the availability checker free?
Yes, with no sign-up. Your allowance of searches refills every few minutes.
