The only way to be sure that what you are buying is “official” is to purchase your tickets from a company that has agents that will purchase in the real world the Powerball tickets online that you have selected. If you are a more trustworthy person and don’t need a scanned copy of your Powerball tickets online then by all means go for an online lottery ticket provider that follows the insurance model. 
Reflecting common practice among American lotteries, the jackpot is advertised as a nominal value of annual installments. A cash value option (the usual choice), when chosen by a jackpot winner, pays the approximate present value of the installments. Mega Millions' previous format began on October 19, 2013; its first drawing was three days later. The current version of Mega Millions uses a 5/70 (for the white balls) plus 1/25 (for the "Mega Ball") double matrix to select its winning numbers.
Every jurisdiction has its own law on winners remaining anonymous. Some jurisdictions are required by law to provide the winner's name, city of residence, game won and prize amount to any third party that requests the information. Other jurisdictions allow winners to create trusts to shield their names from the public, or otherwise claim prizes anonymously. Check with your lottery to see if taking a photo of the winner is required and what its rules are on prize claims. Even if you keep your identity secret from the media and the public, you will have to be known to the lottery so officials can confirm you are eligible to play and win, as well as other legal requirements.

Mega Millions' second-largest jackpot, $648 million, was for the December 17, 2013 drawing. Two winning tickets, one each from California and Georgia, were sold.

The holder of the California ticket claimed on January 3, 2014. (The California ticket holder received an equal share, but potentially a larger cash-option amount, as California lottery winnings are exempt from state income tax)."[3][4][5][15] [16]
