On the left-hand side of the page, click the “About” link
Under the “General” heading, click the “Create Page @username” link
In the pop-up, enter a username for your page
A Few Things To Note:
You must have at least 25 followers to customize your URL, if you have less than this, you will not see the “Create Page @username” link
Your new custom name should be the name of your company
Instead of spaces, use dashes between words
If there is already a page with the name you want, the system will not let you select that name; in this case do not add a “2” at the end, just further customize the name
