Federal investigators say these allegedly sham charities are praying on people's generosity.
The crackdown involved 48 states, including California.
"In these difficult economic times, Americans want to make every contribution count," said FTC Chairman Jon Leibowitz. "The good news is they're still being generous and donating to charitable organizations, including those that support our police officers, firefighters, military families, and veterans. The bad news is that some unscrupulous operators have seized on this goodwill to make a quick buck. The actions we're announcing today demonstrate that federal and state partners will find charity scammers and we will stop them."
