In the USA, due to 'sunshine' laws, one cannot hide their name or hometown from public access.
In order if I won big, after recovering from the shock:
Not tell anyone - even my mom - until I contact a lawyer.
Contact a lawyer experienced with those whom had won big lottery prizes and make a will, financial arrangments to make sure the taxes got paid, and how I would handle my payment in a secure and proper way and how to gift money to family members.
Contact all of credit agencies and notify them that I need to be notified before anyone accesses my info.
Change my home phone number.
Make reservations in a higher level hotel in a nearby area for a couple of weeks.
Then tell family - Go claim my prize - Process the check.
Give some gift monies to parents, brothers
Tell my employer I quit, and to make arrangements to buy into health insurance via them (under laws allowing up to 2 years) and for my retirement/401(k) monies transfers
After a month or 2, then travel for a month and spend several months in the 1st year all around the USA and the world.
Maybe buy a modest new car (had my eyes on a Mazda 6 a few months ago)
Buy a modest house or condo/townhome near where I live, spend some time fixing it up.
After a year or 2, maybe buy a small business to keep me out of trouble.
By the way, the recent winning ticket in the Big Game with a Annunity prize of $250 Million, was sold at a store in a town about 2 miles from me, in Rutherford, NJ
. Of course, it wasn't me.
