And the only plausible way they got around is likely recycle previously used real tracking numbers because USPS is inept (the thing USPS has been constant and consistent is raising prices).

We would never know how since that's the part USPS redacted heavily.

I wish Anthropic/OpenAI FDE take over USPS IT altogether.

> how are they showing up in USPS and UPS databases?

Are you overestimating their validation capabilities? Maybe the validation just isn't that accurate or isn't always done, for efficiency.

I once desperately needed a (FedEx or UPS) package that was delayed. Tracking showed it in a facility about an hour away so I asked if I could pick it up there. I was told: 'It's not really there; our (customer-facing) tracking shows where packages should be.'

Their image of super-efficiency is for selling themselves. (If you are deep in e-commerce, you probably already know.)
