Do you have so many friends on Facebook that sometimes you forget who they are? Me neither, but some people are super popular and need a reminder about whether they're talking to Matt from work, Matt from college, or Matt from the bar last weekend.

For those folks, Facebook is adding "caller ID" for Facebook Messenger. Now, when someone contacts you on the chat app, Facebook will display a larger photo and identifying information.

In a screen shot posted by Facebook's David Marcus, Messenger displayed info like hometowns ("Also from Myrtle Beach, SC"), occupation, and current location.

As TechCrunch noted, the move hints at Facebook's effort to connect you with people beyond your existing circle of friends. "The younger generation seems less dedicated to LinkedIn, which feels like it's lagging behind when it comes to mobile and messaging. Facebook might be happy to fill in," the blog said.

This is not to be confused with Facebook's standalone "Hello" caller ID app, which connects with Facebook to tell you who's calling on the phone—even if you don't have their number saved in your phone.

When someone calls your phone, the Hello app will show you their name and photo along with other information like their work title, birthday, and whether you have any mutual friends—to help you decide whether to pick up or press ignore.

For now, however, Hello is only available on Android.

Everyone else can busy themselves with Messenger, which Facebook pulled out of the main Facebook app last year. Anyone who wants to chat on their phones now has to have Messenger installed. It's still available on the desktop and via the standalone Messenger site, though.
