Retrieve Facebook Page ID
You can use the following tool in order to retrieve your Facebook Page Numeric ID. First make sure that you have no active geographical or age restrictions set in place. The page also needs to be visible to the public and published. Also make sure to temporarily disable adblock if you have it enabled with a social list loaded.
After that, enter the full url to the Fanpage or Page (not your personal profile) in the input field below (copy it from your browser url bar).
