How do you report an account or Page that’s pretending to be you or someone else?

Accounts and Pages that impersonate other people aren’t allowed on Facebook. If you see an account that’s pretending to be you, someone you know, or a public figure (example: celebrity, politician), we encourage you to let Facebook know. You can report potentially impersonating accounts to Facebook whether or not you have a Facebook account.
If you want to report an account for impersonation, first determine if you’re reporting a profile or a Page.

If you have a Facebook account and want to report a profile:

  1. Go to the profile of the impersonating account.
    o If you can’t find it, try searching for the name used on the profile or asking your friends if they can send you a link to it.
  2. Click on the cover photo and select Give feedback or report this profile.
  3. Follow the on-screen instructions for impersonation to file a report.
    If you don’t have a Facebook account and want to report someone that’s pretending to be you or someone you know, please fill out this form.

Note: the steps above are for reporting a Facebook profile. To report a Facebook Page that’s impersonating a public figure, please fill out this form.
If the impersonating account is only on Messenger, learn how to report it to Facebook.

To report impersonation on Instagram, please visit the Instagram Help Center.
