Facebook is a community where people use their authentic identities. We require people to provide the name they use in real life; that way, you always know who you're connecting with. This helps keep our community safe.
You may be having trouble changing your name if:
Your name doesn't follow our name policy
You changed your name in the last 60 days
You were previously asked to verify your name on Facebook
You can also add another name (ex: maiden name, nickname) to your profile. If your first and last name isn’t listed on your account and you’re unable to change it, let us know.
