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. 
Note: As indicated in the instructions, for the purposes of eligibility some countries include components and dependent areas overseas.  If you are a native of a dependency or overseas territory, please select the appropriate country of eligibility.  For example, natives of Macau S.A.R should select Portugal, and natives of Martinique should select France.

The conditions for Florida joining Powerball included a move of the live drawings from Iowa to Universal Studios in Orlando. The three hosts rotating announcing duties from Universal Studios were Tracy Wiu, Elizabeth Hart and Scott Adams (MUSL headquarters remained in Iowa, where its other draws are held). The wheel that was used to determine the Power Play multiplier was retired when the drawings moved to Florida; a random number generator (RNG) was used until the 2012 format change.
Powerball winnings in California and Pennsylvania are subject to Federal income tax only. There is no state income tax in Florida, South Dakota, Texas, Washington and Wyoming, and only on interest and dividends in Tennessee and New Hampshire. Winnings from tickets purchased outside of one's home state may be subject to the income tax laws of both states (with possible credit based on the two jurisdictions.)

If you fail to list all of your eligible children and/or your spouse, it will result in the disqualification of the entire case and the immigration visa will be rejected at the time of visa interview. Of course, if you had any children born after you made the application and before the visa was issued, you could obviously not include those children in the original application and they would still get the immigrant visa.

These changes were made to increase the frequency of nine-figure jackpots; a Powerball spokesperson believed a $500 million jackpot was feasible (it became a reality within the year,[15]) and that the 1st $1 billion jackpot in US history would occur by 2012[16] Less than three months after the Powerball changes, Mega Millions' jackpot reached $656,000,000 despite remaining a $1-per-play game.[17] The random Power Play multiplier was retired for a set, fixed dollar amount payout.[18] The $25 million rollover "cap" (creating larger 5+0 prizes) was eliminated.

In spite of the huge popularity of this lottery draw game it is still an unknown to many that you can buy Powerball tickets online, whether you are in the US or not. To be clear, this doesn’t even mean that you have to be a citizen of the US either. No citizenship & not based in the US? You can still play powerball online and buy lottery tickets online for a number of different lottery draw games.
