Google has been under investigation by the FCC for blocking calls to specific rural carriers. Google claims these numbers are costly to connect to because of agreements these numbers have will 900 number operators. In a letter filed with the FCC, Google has decided to scale back the blocking of calls to fewer than 100 numbers in the United States. The 100 numbers Google is still blocking stem from information Google has that leads them to believe that these numbers are involved in various scams. Google will continue to block these numbers to protect their users.
