Before, once you have setup a Username for your Facebook Page, you cannot change it. Now, Facebook has introduced a new feature which will allow you to change the username of your Facebook Page once again for the last no matter how big the page is. To do this,
- Go to www.facebook.com/username.
- Select your desired Facebook Page.
- Enter the new username in the field box.
- Click on “Check Availability” and it will show you whether the new username is available or not.
This feature is pretty useful when you want to change your organization name, website name and you also want to change the branding username for your Facebook Page. But remember,you will only be allowed to change once.
