If you want to make a new page with no name or if you already have a page and would like to have no name on it then follow the steps : -
Create a Facebook Page with any name of your choice and category. You can use the Code now also but its better to use it later on. If you want to apply this trick on any of your existing page then simply follow the steps from hereby.
After you have created the page all you have to do is open the page as admin and go to the Page settings.
Now all you have to do is rename the page.
Then remove all the character present in rename box of page name and copy the rest code
"Code=remove all the character and copy the rest code"
Copy the rest code again from rename section after removing the character. Now you have the code to have a page without name. See the picture if you have any doubt.
- Just Click on Change page name and paste the code youv'e copied earlier.
Done.
