How and where lottery results are announced varies by state, but most state lotteries post drawing results on their official websites. As of 2015, LotteryUSA.com posts up to the minute lottery results from a variety of states.
Some of the major lotteries in the United States covered by LotteryUSA.com include Powerball, Mega Millions, Hot Lotto, NY Lottery and CA Lottery.
Although going online is a great way to check lottery results, customers need to remember that posted numbers are not necessarily official. In the event of an error, the winning numbers and prize amounts are determined from the official lottery records, not the online site.
