New Jersey does not have laws in place that allows lottery
winners to remain anonymous. You will have to identify yourself
when you go forward to collect your winnings.
Most probably it is a Lottery Scam. Victims never receive this
money but are tricked into sending money to the criminals, who
remain anonymous. They hide their real identity and location by
using fake names and postal addresses as well as communicating via
anonymous free email accounts and mobile phones.
It allows you to remain anonymous as some websites or computer
systems will not allow you to access a select amount of websites,
or if you would like all of your search history to remain anonymous
in case of theft or hacking of files.
