I started thinking about permutations of the idea.Let's assume I am preparing a bulk shipment and I wish to be as certain as possible that a buyer's address is valid and they will almost certainly receive the product, thereby minimizing my risk of a credible claim of non-delivery.DCNs only verify delivery to an address, not receipt by my intended recipient. So what if (for bulk, not worth it for small things) there was a 2 part shipping process. The first package is a dummy, but it contains a small piece of paper with a code in it. This code must be emailed/PM'ed back to me to confirm full receipt. I can then ship confident that the bulk shipment is likely to go through. Between this and a DCN on the second package it is extremely likely any claim of non-receipt can be confidently disregarded.Is there a security risk or hazard with this idea I'm not seeing?Hi Philter3,An excellent idea - I say this quite modestly as I used to use a similar system when selling diamonds in my time before S.R i.e sending a special code to an address in order to confirm it's valid for new buyers. I got the idea from a legitimate home based business I had as a kid selling books via Amazon (they used to do this to verify the address you provided). Having said that, I would like to point out that if it came down to it, all you would be able to prove if you sent a code to an address was just that - to put it another way if you failed to receive a package in the mail, just because it's the first time this has happened would not mean it could never have happened!A far better way would be to send the package itself via Registered Mail - sad to say most buyers won't go for this as it's a common technique for LEO to use to prove a person intended to take possession of goods.V.
