There are still some "Forever" stamps (those with pictures on or Christmas Stamps) but the old non-QR code non-forever stamps stopped being legal a while back (but you can always swap them for the new ones for free).
I've had people try and reuse a QR-coded stamp, you just get a postcard saying there's an item of mail with invalid postage for you to collect (and pay for). You get to look at it before you decide whether to pay the fine or not and then your argument is with the sender to reimburse you or not.
This was almost my thought for mitigating USA stamp fraud. Exchange Forever stamps for $currentValue stamps, but show your ID so you’ll be subject to extra scrutiny if you try to trade in a million of them. (QR code’s better and more fair.)
What about the marginalized communities who don't have IDs, or are you saying USPS needs more security than federal elections?
The basic split between what has barcodes and what doesn’t it that the everyday “definitive” stamps (both 1st/2nd etc. and those with a direct monetary value) were withdrawn and reissued with barcodes, but commemorative and special stamps weren’t. Basically, stuff sold to stamp collectors to be put in a box and never used on postage doesn’t have them.
Reminds me of our monetary stamps. They were the old fashioned monetary value stamps which had a fixed value on it, so when the price hiked you could get 5ct/1ct stamps to add to get to the new rate, fixed value of the stamps stayed the same. People added real money to it since they were not going to buy a full sheet of 5ct stamps for one older one to compensate. And since the mail usually didn't care you sometimes got a free 5ct coin as recipient! (As a kid this was always fun to receive).
Fun thing is that those coins are way heavier than the paper so adding them might get you onto the next cost bracket making the whole excersize pointless.
Also if you mail stuff this way you’ll have mail inspected for bombs or anthrax.
Numbers for demonstration only
They've been underfunded for a long time. Meanwhile they still have the legal requirement to deliver everywhere in the US. So the big guys like Amazon will happily deliver their own packages in densely populated areas where it's easily profitable. The areas where it's not can be done by USPS...
So basically the taxpayer is paying for Amazon to not have to deliver where it would be costly for them.
Just as a datapoint, the USPIS has a >= 98% conviction rate for cases that go to trial
The USPS is also, ahem, rather incompetent, and their own report [1] shows that "mitigation efforts are limited, with no substantive approach to identify counterfeit stamps in the Postal Service network. While the Postal Service and the Postal Inspection Service have increased prevention-related efforts, the quantity of counterfeit stamps in the network remains unknown."
So the increased value of the stamps, the inability to change old Forever stamps, and the lack of enforcement have created a perfect storm for the counterfeiters.
