Question #90134 posted on 07/24/2017 3:08 p.m.

'Sup 100 Hour Board,

I saw this USPS blue box. It gives a warning about seeing anonymous mail. I'm just wondering, what counts as anonymous mail? Those that are sent without a return address, packages sent without any destination or return address, or is it simply Anonymous mail?

Dear Soaring High,

It seems as though it really is just mail that's supposed to be anonymous. Apparently there are even services to send mail anonymously. My guess is that the sign is specifically referring to mail sent by such services.

A reader emailed me the following information pertaining to the question after it posted, and I thought it would be good to include in a correction:

"Regarding board question 90134, I would refer you to the Postal Service handbook, for example, http://about.usps.com/postal-bulletin/2012/pb22353/html/updt_011.htm.

So any package weighing more than 13 ounces or requires a customs declaration or has a handwritten customs declaration must be presented at the counter; otherwise it is considered anonymous and will not be delivered.

http://about.usps.com/handbooks/sp1/sp1_c3_022.htm also discusses packages that are found in unattended locations."
