Platform Update: Facebook Lets Developers Ask a User for Their Address, Phone Number in the Graph API

In another part of its effort to become the main artery for social data, Facebook is now allowing developers to ask a given user for their physical address and phone number within the user object of the Graph API.


This information, announced as part of this week’s developer blog post update, helps anyone from game developers to mail and phone marketers reach directly to where users are at all times.


It’s especially valuable because it’s so sensitive, so Facebook requires developers to ask for a separate set of permissions within the main “Request for Permission” interface. Now developers can build applications that leverage this new access to user data, though note that developers can only be granted access to the address and mobile phone number of the user authenticating the application – not that user’s friends as well.

Given this new sharing option, users should be even more careful about what they see on the permissions page, rather than just clicking through. While quick sharing makes for a more seamless user experience, we could see Facebook itself providing an additional prompt asking users to confirm that they want to share this information, in order to help prevent accidental sharing.

Facebook also goes out of its way in the developer post to explain that users are only sharing information about themselves, not their friends.

The other piece of news from the post this week: Facebook has added a long-requested way to subscribe to the “edge.remove” to track when a user unlikes a page.
