Facebook has taken a step further to create transparency for its users particularly in the United States. Its users in the United States who want to run certain advertisements on the platform will need to hand over the last four digits of their social security number and a picture of a government-issued ID. This according to CNN, reports that the social network now requires anyone who wants to run ads related to political campaigns, civil rights, immigration, guns, economy, and other issues, to prove they’re in the United States. Part of the proof required is the last four digits of your Social Security number. The move is part of a series of initiatives by Facebook to increase transparency on the platform after a Russian government-linked troll group spent thousands of rules on Facebook ads targeting Americans ahead of the 2016 presidential election. In addition to a Social Security number, users wishing to buy ads will need to provide a picture of a government-issued ID and a US mailing address. Once Facebook verifies the information submitted, the company will mail a code to the provided address to authorize the user’s Facebook account to buy ads. Facebook declined to share what services it uses to verify Social Security numbers and other personal details. The company said it will delete the information after verification.” This normally happens within six weeks,” the company says on its website.
