Pro Tips

Tips for choosing a great username

Pick a username that works everywhere and stands the test of time.

1

Keep it short

Aim for 15 characters or less. Short usernames are easier to remember, type, and share across all platforms.

2

Be consistent

Use the exact same username on every platform. This makes it easier for followers to find you everywhere.

3

Avoid numbers

Unless they are part of your brand, numbers in usernames can look spammy and be harder to remember.

4

Check variations

If your ideal name is taken, try variations with "the", "real", "official", or your niche keyword.

5

Act quickly

Usernames get claimed fast. Once you find an available name, register it on all platforms immediately.

FAQ

Frequently asked questions

Everything you need to know about checking username availability.

How does the username availability checker work?
Enter your desired username and the tool checks whether it is available across multiple social media platforms including Instagram, TikTok, YouTube, X (Twitter), LinkedIn, and Facebook. Results are displayed instantly so you can see which platforms have your username available.
Which platforms are supported?
Currently we check username availability on Instagram, TikTok, YouTube, X (formerly Twitter), LinkedIn, and Facebook. We are continuously adding more platforms to give you a comprehensive view of your username availability.
Is the username checker free to use?
Yes, completely free with no limits. You can check as many usernames as you want, as many times as you want. No signup, no credit card, no hidden fees.
How accurate are the availability results?
Our checker queries each platform in real-time to determine if a username is taken or available. Results are highly accurate at the time of checking. However, usernames can be registered at any time, so we recommend claiming your username quickly if it is available.
Can I check usernames for private accounts?
Our tool checks whether a username is already in use, regardless of whether the account using it is public or private. If a username is taken by either a public or private account, it will show as unavailable.
What makes a good username?
A good username is short (under 15 characters), easy to remember, uses only letters and numbers, avoids special characters, is consistent across platforms, and reflects your brand or personality. Use our Username Generator tool for ideas.
What should I do if my username is taken?
If your preferred username is taken on some platforms, try adding a prefix or suffix (like "the", "real", or "official"), using underscores or periods, adding your niche, or trying a variation. Consistency across platforms is ideal but not always possible.
