I tried signing up for this 3 months ago, and was shocked to receive images for the mail of literally <i>everyone</i> in my building (I'm one of seven apartments).<p><i>Huuuge</i> privacy violation. (It's just images of the envelopes, but that still tells you a lot.)<p>I unsubscribed and then went to file feedback, and got an immediate reply explaining this was <i>by design</i>:<p>> <i>Thank you for participating in Informed Delivery®. You recently reported that you are receiving images for other units in your apartment complex. This is due to the fact that your unit/complex is not coded down to a unique delivery point barcode, which is a requirement for this service.</i><p>> <i>In order for the feature to provide mail images to the appropriate recipient(s), each multi-unit building on each carrier route must be individually identified and coded to the unit level. While most addresses are coded at this level, this coding process, especially in high density areas, is a work in progress. If you live in multi-unit building and you have successfully registered on usps.com ®, but the sign up process indicates that you do not have an eligible address, we are unable to offer you the feature until the coding is complete. Please check back at a later date.</i><p>It seems insane that if my building isn't "coded" I see <i>everyone's</i> mail instead of nobody's.<p>And it's not like I'm in the middle of nowhere -- I'm in Brooklyn, half a block away from an express train stop. And the post office knows about our different addresses -- I mean, they deliver mail directly into our individual locked mailboxes.
