It looks like Caller ID as we know it is about to change in a major way.

It appears that Facebook may have found a way to solve our awkward problems when unknown numbers try to call us.

Usually, we either just answer these calls or send them a message to ask them who they are.

Either way, we know subconsciously that there’s a degree of risk involved in answering phone calls from unknown callers.

Thanks to Facebook, however, that predicament we sometimes find ourselves in is likely about to be gone forever.

The social media giant just recently launched the Facebook Hello app, which aims to change Caller ID as we know it. The app, which is currently on beta testing for Android users in the U.S., gives users more control over the calls they receive.

The Facebook Hello app works like the built-in Caller ID feature in most (if not all) mobile phones that people use today, but with a huge twist: it will tell you who is calling you even when the caller isn’t on your contacts list.

Unknown numbers who try to contact Facebook Hello app users will be identified through their publicly available details on Facebook’s social networking site.

But that’s not all.

Facebook Hello app also lets its users block unwanted callers, and it also tells them how many users have already blocked these callers.

In a blog post, Facebook Product Manager Andrea Vaccari told:

“Billions of calls are made everyday on mobile phones and people often have very little information about who’s calling them.

“Today we are starting to test Hello, a new app built by the Messenger team.

“Hello connects with Facebook so you can see who’s calling, block unwanted calls and search for people and places.”

Facebook’s Hello app will only be able to share information that the caller has already made available on Facebook.

Callers who have chosen not to link their phone numbers to their Facebook accounts will still remain unidentified— and this, some say, could be the biggest hurdle that the app will have to face.

But the app does have features that could come in handy. Aside from being able to identify callers whose phone numbers are associated with their Facebook accounts, Facebook Hello also gives users the option to automatically block users who have already been blocked by many others— like spam callers.

If Facebook’s Hello app proves itself successful during its beta testing stage, the app may soon be available on other mobile platforms in all other regions.
