CAN I BUY POWERBALL TICKETS THROUGH THE INTERNET?
Some state lotteries do sell TO THEIR RESIDENTS through the Internet but not across their state line. Powerball tickets can only legally be purchased at a state lottery sales terminal in the lottery jurisdictions that sells the Powerball game. A lottery can also legally sell tickets on the Internet, but only to persons within its own state. No one can sell lottery tickets by mail or over the Internet across state lines or the U.S. national border. No one except the lottery or their licensed retailers can sell a lottery ticket. No one.
Law prevents the SALE (exchange of consideration) of any interest in the outcome of a gambling event. If you are not buying from a licensed retailer in the state or from the state lottery site (within the borders of that state), then you should not expect to be able to collect your prize. There are no regulations of websites that claim to sell tickets or to sell you a "service" to buy and hold tickets for you. Many lotteries believe that they would violated state and federal laws is they paid on those tickets purchased (if actually purchased) by an unlicensed reseller.
