How to Check Your Facebook ID
Websites often identify users by user IDs. When you join Facebook, the site assigns you a specific user ID. This ID becomes part of your profile along with your username and other information you provide when you join Facebook. You may never have to use your Facebook ID, but if you wish to check it, you can do so from your Profile page.
Find ID for Normal Accounts
Log in to your Facebook account, and examine the URL that appears in your browser's address bar at the top of the page. The beginning of the URL appears as follows:http://www.facebook.com/A name may appear at the end of that URL after the final "/" character. For instance, the URL may appear as shown below:http://www.facebook.com/jsmithIf your URL has a name at the end of the URL as shown above, write that name down, and proceed to the next section to learn how to check your Facebook ID. Otherwise, continue to the next step.
Click the "Profile" link in the page's upper-right corner. Your Profile page appears.
Examine the URL in your browser's address bar. It changes after you click the "Profile" link. Locate the string, "profile.php?id=" in the URL. Your Facebook ID, a number, appears after the word "id=." Write that value down for future reference. You do not need to review the next section.
Find ID for Personalized Accounts
Type the following text in your browser's address bar:https://graph.facebook.com/xyzReplace "xyz" with the name you wrote down in the previous section.
Press "Enter." Your browser navigates to a special Facebook Web page that displays information about your account.
Locate the number next to the word "id." Write that value down. It is your Facebook ID.
Tips & Warnings
- The methods for checking a Facebook ID differ according to the type of account you have. If you see a name in your Facebook URL, you have a personalized account that allows your Facebook URL to contain a name of your choice. You can then use that name -- as shown in the previous section -- to query a special Facebook service that returns your numerical Facebook ID. Users without personalized accounts can simply view their IDs in their browser's URL bars after clicking the "Profile" link as described in Section 1.
