You can change your last name on Facebook through your settings, and the change takes effect immediately

Open Facebook and click the downward arrow in the top right corner, then select Settings and privacy followed by Settings. On the left side, click Personal information, then find the Name field. Click Edit next to your current name. Type your new last name in the appropriate field, then click Review change. Facebook will show you how your name will appear across the platform. Click Save changes when you're ready.

The change appears on your profile and in comments, posts, and messages within minutes. People who already know you won't receive a notification that your name changed, but your friends can see the update on your profile if they visit it. If you change your name frequently, Facebook may restrict how often you can make changes — typically you can change it once every 60 days, though this limit sometimes varies.

Key Takeaways

  • Access your name settings through the downward arrow menu, then Settings and privacy, then Settings, then Personal information.
  • Facebook shows you a preview of how your new name will appear before you confirm the change.
  • The change takes effect immediately across your profile, comments, and messages.
  • You can typically change your name once every 60 days, and Facebook may temporarily block changes if you modify it too frequently.
  • Your friends won't receive a notification about the name change, but they'll see it if they visit your profile.

What happens to your old name after you change it

Your previous name doesn't stay visible on your profile or in your activity. When you change your last name, Facebook replaces it everywhere — in your profile header, on your posts, in comments, and in messages you've already sent. People viewing your old posts will see your new name, not the name you had when you posted.

Facebook keeps a record of name changes for security purposes, but only you and Facebook can see this history. Your friends cannot view a log of your past names. If you want to revert to a previous name, you can change it back at any time, subject to the 60-day restriction between changes.

Reasons Facebook might block a name change

If you've changed your name multiple times in a short period, Facebook will prevent you from making another change for about 60 days. This limit exists to prevent account abuse and impersonation. The restriction applies even if you're trying to correct a typo or change back to your original name.

Facebook also has rules about what names are allowed. You cannot use numbers, symbols, or characters that don't appear in standard names. Titles like "Dr." or "Jr." are sometimes permitted but not always. If Facebook rejects your name change, the system will explain which characters or words are not allowed. You can then edit your entry and try again.

Changing your name on mobile versus desktop

The process is nearly identical on both mobile and desktop. On a phone or tablet, tap the three horizontal lines (menu) in the bottom right corner of the Facebook app, scroll down to Settings and privacy, tap Settings, then tap Personal information. Find Name and tap Edit. The rest of the steps match the desktop version.

Mobile sometimes loads the settings page more slowly, especially on older devices or slower connections. If the page doesn't load fully, try closing the app completely and reopening it. Desktop is often faster if you're making multiple changes to your account at once.

How to change your name if you've hit the 60-day limit

If you see a message saying you cannot change your name right now, you've hit Facebook's rate limit. The only solution is to wait. The 60-day timer resets from the date of your last name change, not from when you first tried to change it. If you changed your name on March 15, you can change it again on May 14.

If you believe the restriction is an error — for example, if you changed your name long ago and the system is still blocking you — you can contact Facebook through the Help Center. Go to Settings, scroll to the bottom, and click Help Center. Search for "name change" and look for the option to report a problem. Explain your situation, and Facebook's support team will review it, though responses can take several days.

Changing your display name versus your legal name

Facebook uses one name field for both your display name and your legal name. When you change your name in settings, you're changing what appears everywhere on the platform. There is no separate "display name" option like some other social media platforms offer.

If you want your profile to show a nickname or shortened version of your name, you can use that in the name field — Facebook allows this as long as it follows their naming rules. For example, you could use "James R." or "Jamie Rodriguez" instead of your full legal name. Just remember that whatever you enter will appear on all your activity across Facebook.

What to do if someone else's name appears on your account

If your profile shows a name you didn't set, your account may have been compromised. Change your password immediately by going to Settings, clicking Security and login, and selecting Change password. Then go to Personal information and correct your name back to what it should be.

After you've secured your account, check your login activity. In Settings, click Security and login and scroll to Where you're logged in. If you see logins from places you don't recognize, click the three dots next to each one and select Log out. Consider enabling two-factor authentication for extra security: in Settings, go to Security and login and turn on Two-factor authentication.

Frequently Asked Questions

Can I change my first name and last name at the same time?

Yes. When you click Edit next to your name in Personal information, you can modify both your first and last name in the same action. Facebook treats this as a single name change, so it counts as one change toward your 60-day limit.

Will my friends get a notification when I change my last name?

No. Facebook does not send notifications when you change your name. Your friends will only see the new name if they visit your profile or see your activity after the change. Some friends may not notice the change at all.

Can I use a fake last name on Facebook?

Facebook's rules say you must use the name you go by in everyday life, but enforcement is inconsistent. You can use a nickname, shortened version, or name you commonly use, as long as it doesn't contain numbers or symbols. If Facebook flags your name as fake, you'll receive a notification asking you to change it to a "authentic name."

What if I want to change my name back to what it was before?

You can change your name back to a previous name at any time, but you still have to wait 60 days between changes. If you changed your name on March 1 and want to revert on March 15, you'll have to wait until May 1 to make the change.

Does changing my name on Facebook change it anywhere else?

No. Changing your name on Facebook only affects your Facebook profile and activity. It does not change your name on Instagram, Messenger, or any other platform, even if those accounts are linked to your Facebook account. You would need to change your name separately on each platform.
