How to Change Your Business Page Name on Facebook
You've created a Facebook fan page for your business, but you want to tweak the title. The good news is, if you've just created the page, it can still be done. The bad news -- if you've had your fan page for a while and already have more than 100 fans, you won't be able to change the page name. If you have fewer than that, you can change the fan page name, but the username -- or the URL for that page -- will stay the same. If you're determined to change the page name, in that case, you'll have to create a completely new fan page.
Log in to your Facebook account with your username and password. Navigate to the fan page you would like to change.
Click "Edit Info" near the top of the fan page. You can also click "Edit Profile" and then choose "Basic Information" from the right-hand menu.
Click on "Name" and enter in the new name for the page. If your page already has more than 100 fans, you won't be able to use this option.
Click "Save Changes" at the bottom of the page. Your Facebook fan page name should update automatically across the platform.
