Short answer. If your Instagram account was disabled for impersonation, the notice says the profile was pretending to be someone else. Appeal from that screen, say you are the person behind the account, and complete the video selfie in the app. Do not send the ID to us.
Instagram account disabled for impersonation is a specific disable message: the account was flagged for pretending to be someone else. You will see it at login. The appeal is the button on that notice, plus a check that you are the person the profile represents.
Say who you are, then do the check in the app
Screenshot the exact sentence. Request a review. In the note, lead with the fact that you are the real owner. Add the username, the date, and whether this is your personal profile, creator page, or shop. If someone else took the account and changed the name, say when you lost it.
Instagram can ask for a video selfie or an ID. Do that inside the app. One face, clear light. Instagram selfie video verification is the clip. We do not want the file sent to our inbox.
Send the username and the impersonation screenshot. We file through Meta’s own official channels, open support chats, send follow-up emails, and push the case hard until it gets looked at. It takes a few days. Start a case on the contact page. How it works is the three steps. We never ask for your password.
