What characters are allowed in Twitter/X usernames?

Twitter/X usernames (handles) can contain letters (A-Z, a-z), numbers (0-9), and underscores (_). Usernames must be between 4 and 15 characters long. Spaces, periods, and special characters like @, #, !, etc. are not allowed in the handle itself.

How do I know if a Twitter/X username is available?

Use our Twitter/X username checker to instantly verify availability. Simply enter your desired username and click check. The tool will tell you if it's available or taken. Note: This tool may require Twitter/X API access or manual verification for full functionality.

Can I reserve a Twitter/X username?

Twitter/X doesn't have a username reservation system. If you find an available username you like, create your account immediately to claim it. Usernames are assigned on a first-come, first-served basis.

What makes a good Twitter/X username?

A good Twitter/X username is memorable, easy to type, consistent across platforms, professional (avoid excessive numbers or underscores), and reflects your brand or identity. Shorter is often better - aim for 10 characters or less if possible.

Can I change my Twitter/X username later?

Yes, you can change your Twitter/X username at any time through your account settings. However, changing your username may confuse followers and break existing mentions. Your old username becomes available for others to claim immediately after you change it.

Why is my desired Twitter/X username taken but the account appears inactive?

Twitter/X reserves certain usernames (like brand names or prohibited words), suspended accounts may keep usernames locked, or the account might be private or inactive. Twitter/X has a policy for reclaiming inactive usernames, but this process is not automatic.

What's the difference between Twitter and X usernames?

There's no difference - Twitter rebranded to X in 2023, but the username system remains the same. Usernames still start with @ and follow the same rules (4-15 characters, letters, numbers, and underscores only).

Twitter/X Username Best Practices

Keep It Short

Shorter usernames are easier to remember, type, and mention. Aim for 10 characters or less.

Make It Memorable

Choose something unique and easy to remember. Avoid generic names that blend in.

Match Other Platforms

Use the same username across all social media for consistent branding and easy discovery.

Be Professional

If using Twitter/X for business, choose a professional username that reflects your brand.

Avoid Random Numbers

Adding random numbers like "user12345" looks unprofessional and is hard to remember.

Don't Use Multiple Underscores

Excessive underscores make usernames difficult to type and share verbally.

Avoid Confusing Characters

Don't mix lowercase "L" and uppercase "i" or numbers that look like letters (0/O, 1/l).

Don't Impersonate

Never choose usernames that impersonate brands, celebrities, or other users. It violates X policies.
