Does calling 112 provide a direct link to 'state trooper info' in all 50 states?

The official local and nationwide emergency number in the United States is 911, while 112 is a global emergency number primarily used in European countries.

The claim in a social media post that calling 112 brings help in the U.S. and is a way to verify if an unmarked police car is legitimate is false on both counts. The 9-1-1 Association (the National Emergency Number Association, or NENA) debunked the claim as long ago as 2013, with that organization calling it "bad advice."

The post lays out a dramatic purported scenario of a woman being followed by what could be an unmarked police car, she calls 112, help arrives and it turns out the car following her was being driven by a criminal. But the scenario lacks any details of date, location or police involved.

The post simply urges readers to share its bogus information.
