It is a scam:
http://info.pch.com/consumer-information/fraud-protection

Publishers Clearing House never requires any money, purchases, taxes, fees, or deposits of any kind to get your prize.

Publishers Clearing House DOES NOT call, email, FAX, mail, any advanced notice that you have won.

"If you are ever contacted by someone claiming to represent PCH, or claiming to be one of our employees,  and asked to send or wire money (for any reason whatsoever, including taxes); or send a pre-paid gift card or Green Dot Moneypak card in order to claim a sweepstakes prize – DON’T!  It’s a SCAM. If you are sent a check, told it’s a partial prize award, and asked to cash it and send a portion back to claim the full prize award, DON’T.  The check is fake, but the SCAM is real!

Publishers Clearing House does not operate this way and would NEVER ask for money to claim a prize award.  PCH employees would never contact you personally or in advance to notify you of a prize award.  Our prize awards are presented just the way you see in our popular TV commercials, ‘live and in person’ by our Prize Patrol, with balloons, champagne and check in hand - - and with no advance notification!"

Thanks for the heads up. I got this call a few minutes ago. It went unanswered because I did not know the number.
