Google is preparing to roll out a feature that will help cut down spam calls by verifying calls before they’re placed.

In a support document, Google outlines how Verified Calls will work. Participating businesses will send information to Google’s Verified Calls server, including the name of the business, who they’re calling and the purpose of the call.

Google then sends this information to the Android Phone app. Once the business actually places the call, Android compares the call with the information Google previously sent. If everything matches up, the Phone app displays a “Verified Call” badge.

While certainly an intriguing feature, and one with a lot of potential, it remains to be seen how many users want Google knowing exactly why a business is calling them. For those who want to keep Google from knowing too much about their business, the feature can be turned off.
