I have received comments about my blog post on @[4:0] = Mark Zuck. Sorry folks, I have not posted replies or explained about that.
Well. I managed to find out the reason, information and the history for it. :)
1.) Each of our FB account is tagged to a number. That’s the profile number. Note that not too long ago, FB allowed users to change their profile page (the page where visitors first view your information) to a ‘vanity’ name. That is- a customized name. For example, www.facebook.com/Zuck.
2.) With this changes, it does not mean that your profile number goes away. It is still there.
3.) So when we type @[4:0], we get Mark Zuckerberg. Why is that so? This is because Mark’s FB profile ID is 4.
Now you must be wondering why did the FB creator chose 4 instead of 1? Haha. This is because he used numbers 1-3 initially to test FB; and the profiles no longer existed.
Now we come to the question- can we type @[our profile number:0] to get our names? Yes, you can. But this begets the question- you have changed your profile page to a vanity name, how do you get the profile number?
Finding your FB profile number
There are 2 ways:
1.) https://graph.facebook.com/ method.
Go to https://graph.facebook.com/(type your FB vanity name in the “username” here, without the brackets). For example, https://graph.facebook.com/zuck is where “zuck” is the profile name for Mark Zuckerberg’s profile page http://www.facebook.com/zuck.
You should see something similar to the following:
"name": "Mark Zuckerberg",
The "id": "4"- 4 is the ID number .
2.) FB Profile Method
Go to your profile page and move your mouse over your profile image. You should see a link url that comes out at the status bar of your browser.
For example: https://www.facebook.com/media/set/?set=a.11111111111.11111.123456&type=1
The number behind the third dot is your profile ID. In this case, “123456” is the profile ID.
The @[your profile number: 0] “formula”
So if you type @[profile number: 0], you will get the person’s name. J
