Facebook Page names should accurately reflect the Page’s topic. You’ll need to be an admin to request a change to your Page’s name. Changing your Page’s name won’t affect its username.
To request a change to your Page name:
- Review facebook’s page name standards
- Click on Page Settings on the left side of the Page.
- Then click on Page Info
- Under General and Name, click to Edit
- Enter a new Page name.
- Review your request and click Request Change
If you don’t see the option to edit your Page’s name:
- You don’t have a Page role that allows you to change your Page’s name. Learn how to see your Page role.
- You or another admin recently changed your Page’s name.
- There may be limits on your Page.
If you are able to submit a name change request, keep in mind that it may take up to 3 days to review your request and we may require additional information before you receive a final decision. If your name change is approved, you won’t be able to unpublish the Page or change the name again for 7 days. During this 7 day period, we may also let the people who like your Page know the name’s been updated.
