Suppose I receive a piece of mail addressed to my house with my last name, but with a first name I have never heard of. (I don’t know anyone with that name.)
It's from an organization I do have a relationship with, and I believe it is most likely a mistake; and it was meant for me.
The letter itself is not very important, but opening or destroying someone else’s mail is such a serious offense (18 USC 1708 and 18 USC 1702), and I don’t want to risk mishandling it.
I am wondering what should I do with the letter. I’m unsure if it would be appropriate to write "not at this address", because if it was meant for me that might confuse the post office.
Can I open it to check if it really was for me? (Or would that be illegal?)
If I can not open it, can I just bin it?
