When you sign up for a Facebook account for the first time, the service will assign you a numerical ID for your homepage. Needless to say, sharing your Facebook page with others using said numerical ID isn’t exactly what anyone would consider convenient, so why not replace it with a custom URL instead?
Before you start thinking of the URL you would use for your Facebook page, you might want to look at the guidelines below before to make sure that your URL would be accepted:
Now that you know the limitations of the system, here’s how you can change the URL of your Facebook Profile.
In the event that you’re unhappy with your current custom URL, or maybe you think it’s time for a change, all you have to do is access the General Account Settings page and edit the “Username” option once again.
While there are no limits as to how many times you’re allowed to change your URL, do keep in mind that every time you update your profile or page’s URL, it would cause any old links to be invalid.
If someone were to try and access your older links, they would be greeted with the “Page Not Found” error. As such, it is highly inadvisable to change the URL frequently, lest it invites confusion.
