Your X username is the unique handle after @; your display name is a separate profile field. If you only want a different visible name, you may not need to change the handle or profile URL.
Check the current handle rules
X’s username guide specifies more than four characters and a maximum of 15, using letters, numbers and underscores. That means a new handle should meet the service’s current 5–15 character rule, rather than the four-character minimum in older advice.
Change the username
- Open X’s Settings and privacy.
- Find the account/username controls. The web and mobile navigation can differ.
- Complete any required account verification in the genuine app/site.
- Enter an available handle and save using the offered control.
- Open your profile and confirm the new username and URL.
Follow the current help page and prompts if the interface differs. Do not assume every account can make unlimited changes without additional checks.
What changes?
| Item | What to expect |
|---|---|
| Handle/profile URL | The new username changes the address people use to find your profile. |
| Existing account connections | X says existing followers, Direct Messages and replies are not affected by the username change. |
| Previous username | X says it becomes available for someone else to use. |
| Display name | A separate field; choose it independently. |
Update the places where people find you
- Replace the profile link on your website, email signature and other profiles.
- Check printed or saved QR codes that point to the old address.
- Tell followers about the new handle if it could be confusing.
- Confirm any account-specific verification restrictions before changing a business-critical identity.
Do not expect a username change to erase old posts or start a new account. Likewise, old links should not be assumed to redirect permanently to you once someone else can take the old handle.
