Make sure you find out whether you can remain anonymous when you claim your prize, because laws governing lottery wins vary from state to state.
In some places, you can easily shield your identity protected from the public. In other states, it’s impossible. And in some states that require the winner to be announced, the law allows a trust or other legal entity to claim the prize on your behalf, thereby keeping your name out of the public eye.
Also, the standard advice is to sign the back of your winning ticket in case you are separated from it. However, if you end up having the option of claiming your prize through a trust to protect your identity, your signature could interfere with your ability to do that. This makes it important to know your claiming options first.
