You can change your name on Facebook through your settings, and Facebook allows you to do this once every 60 days

To change your last name on Facebook, go to the menu icon (three horizontal lines) in the bottom right corner on mobile, or the downward arrow in the top right on desktop. Select "Settings & Privacy," then "Settings." Scroll to "Personal Information" and tap or click "Name." Edit your last name in the field that appears, then tap or click "Review Change." Facebook will show you how your new name will appear across the platform. Confirm by tapping or clicking "Save Changes."

The entire process takes about two minutes. Your new name becomes visible to your friends and the public (depending on your privacy settings) when ready after you save it. Facebook tracks when you change your name and will not let you change it again for 60 days, even if you want to revert to your old name.

Key Takeaways

  • You can change your last name through Settings > Personal Information > Name on both mobile and desktop versions of Facebook.
  • Facebook enforces a 60-day waiting period between name changes, so you cannot change it back when ready if you make a mistake.
  • Your new name appears to everyone on your profile unless you have restricted who can see your personal information in your privacy settings.
  • If you change your name frequently or use a name Facebook flags as unusual, your account may be temporarily restricted until you confirm your identity.

What happens to your old name and profile history

When you change your last name, your old name does not disappear from Facebook's records. Facebook keeps a log of all your name changes for security purposes. If someone searches for your old name, they will not find your profile — search results show only your current name. However, any posts, comments, or messages you made under your old name will still show your old name attached to them.

Your friends will see the name change notification in their activity feed. The notification says "[Your Name] changed their name" and appears for a few days. This is useful if you are making a deliberate, public change (like after marriage or divorce), but it also means the change is not private.

Why Facebook might block your name change

Facebook has automated systems that flag names it considers unusual, offensive, or potentially fake. If your new last name contains numbers, special characters, or words Facebook's system does not recognize as a real surname, you may see an error message saying "Please enter a valid name." Common triggers include names with apostrophes in unexpected places, names that are very long, or names that look like they contain a username or email address.

If Facebook blocks your change, you have two options. You can try a different spelling or format — for example, using "O'Brien" instead of "Obrien" if that is your actual name. Or you can use Facebook's "Report a Problem" feature to appeal the block. Select the same Settings menu, go to "Help & Support," and choose "Report a Problem." Explain that the name you entered is your real name. Facebook's support team reviews these reports and usually responds within a few days, though they may ask you to provide identification.

Changing your name for privacy or safety reasons

If you are changing your name because of safety concerns — such as escaping harassment, stalking, or domestic violence — a name change alone is not enough protection. Changing your last name makes you harder to find through search, but anyone who already knows your profile link can still access it, and your friends list may still reveal your connections to people you want to avoid.

For stronger privacy, consider changing your profile to "Friends Only" so only people you have accepted can see your posts and information. You can also limit who can search for you by going to Settings > Privacy > Who can look you up using the email address or phone number you provided. If you are in danger, contact a local domestic violence organization or law enforcement before relying on Facebook settings alone. Organizations like the National Domestic Violence Hotline (1-800-799-7233) can help you create a safety plan that includes social media.

How your name change affects your other Facebook features

Changing your last name does not affect your Facebook username (the custom URL you may have set up, like facebook.com/yourname). Your username stays the same unless you change it separately through Settings > Personal Information > Username. This means people can still reach your profile using your old username even after your name changes.

Your name change also does not affect your Messenger account, your Facebook Pages (if you manage any), or your Instagram profile (if your Instagram is linked to Facebook). Each of these has its own name settings. If you want your name consistent across all platforms, you will need to change it in each place separately.

What to do if you change your name by mistake

If you entered the wrong name or changed your mind, you have to wait 60 days before you can change it again. There is no way around this waiting period — Facebook enforces it for all accounts. You cannot contact Facebook support to remove the waiting period or speed up the process.

If you made a typo (for example, you meant "Smith" but typed "Smyth"), your best option is to wait out the 60 days. During that time, you can update your profile photo, bio, and other information to make sure people recognize you. After 60 days have passed, you can go back to Settings > Personal Information > Name and correct it.

Frequently Asked Questions

Can I use a nickname or stage name as my last name on Facebook?

Facebook's rules say you must use the name you go by in everyday life. A stage name or nickname is allowed if it is actually what people call you. However, Facebook's automated system may flag it as unusual. If that happens, you can appeal through the "Report a Problem" feature and explain that it is your real name or the name you commonly use.

Will my friends be notified when I change my last name?

Yes. A notification appears in your friends' activity feeds saying you changed your name. The notification stays visible for a few days. There is no way to hide this notification or change your name privately on Facebook.

Can I change my last name on Facebook if I do not have a phone number or email on file?

You can change your name without a phone number or email. However, if Facebook flags your name as unusual and asks you to verify your identity, you will need one of these to complete the verification. Adding a phone number or email to your account before you change your name can prevent delays.

What if someone else is using my real last name and I cannot change mine?

Facebook does not prevent multiple people from having the same name. If you are getting an error message, it is because Facebook's system flagged the name format as unusual, not because someone else has it. Try appealing through "Report a Problem" with your ID, or try a slightly different spelling if your name has common variations.

Does changing my last name on Facebook change it on Instagram?

No. Instagram has its own separate name settings. If your Instagram is linked to your Facebook account, changing your Facebook name does not automatically update Instagram. You need to change your Instagram name separately through Instagram's settings.
