Deactivation puts your account in a queue for permanent deletion from Twitter. Deactivation is not available on mobile devices and must be done by accessing Twitter.com on the web.
To use a username or email address on another account, you must first change them and then confirm the change prior to deactivation. (See below for instructions.)
We do not control content indexed by search engines like Google or Bing.
After deactivation, your account should be removed within a few minutes, however some content may be viewable on Twitter.com for a few days.
To make your username or email address available for re-use before deactivating your account:
On the web, go to your Settings page from the drop-down menu under the person icon.
In the username field, choose a new username.
In the email address field, change your email address to a new address you own.
Confirm the new email address via a link we send to you (very important!)
Your email and username will now be available to use on a new account if you choose to sign up again during the 30 day deactivation period.
Proceed with deactivation as listed above.
Note: Twitter changes your settings immediately. However, old links may appear on Google and other search engines because they have cached old content in their search index. Twitter has no control over this, but you can send search engines a request to take down your information.
