According to the 2012 "National Do Not Call Registry Data Book", the number of actively registered phone numbers is up, but so too are the number of consumer complaints about unwanted telemarketing calls. The FTC has continued to receive large numbers of consumer complaints about robocalls even though most telemarketing robocalls have been illegal since September 2009. EPIC supported establishment of the Do Not Call Registry, and recommended to Congress in 2010 that an effective Do Not Track initiative would need to ensure that a consumer's decision is "enforceable, persistent, transparent, and simple."
