Saw the number as a missed call on my cell phone. Called back and the woman asked my name, saying she was doing "research" for Publisher's Clearing House.
These people are scammers. This number along with 505-807-5870 "work" together to prey on the elderly. From what I've gathered they use Publisher's Clearing House mailers to get the names, addresses, and phone numbers of the elderly. Then use that to scam them for money, telling whoever mails one back that they've won but in order to collect the money they must first send them a check for x number of dollars.
