Ahead of the 2020 elections, Facebook today announced it’s tightening requirements for groups buying political ads on the social network. The company last year began requiring advertisers get authorized to run ads about social issues, elections, or politics, which involves advertisers providing identification to confirm who they are and where they’re located — including a U.S. street address, phone number, business email and website matching the email. Starting in mid-September, Facebook says advertisers will now need to submit more information about their organization in order to run political ads.

Failure to submit this information will see their ads paused, the company says.
