I received an email that I created a new Facebook account, but I didn’t sign up for a new account.

Most likely, someone mistakenly tried to register using your email address. Do not click the link in the email. If you don’t click the link, the account will not be confirmed. An unconfirmed account can remain on the site for a maximum of three days, but it can’t be used to send messages, write on Walls, post in discussions, poke, tag friends in photos or notes, comment on content, join groups, or like pages. After three days without the email owner’s confirmation, the account will become inaccessible.

If someone created an account to impersonate or imitate you, go to the fake profile and click "Report/Block this person" at the bottom of the column on the left. Check the Report this Person box, choose Fake Profile as the reason, and add "Impersonating me or someone else" as the report type. Be sure to add the web address (URL) of the real profile so that we can review the information.
