Amazon vs USPS tracking. Which one to believe?

[special]

Just tracked a recent Amazon order. Amazon says it's coming in a few days. USPS says it was delivered a few weeks ago, and I do not live in South Carolina.

Same tracking number.

Neither.

I'd believe my eyes when the package appears on the front porch. Other than that, it's a crap shoot with either of them.

And if it is sent UPS Smartpost, just plan for it to never arrive.

Sometimes you get a delivered message when it reaches a distribution point. I've had that happen thinking it went to a wrong address. Very confusing, but now I ignore them, and take it as it's on the way.

Or.. if it's UPS smartpost, the tracking number won't track it until it's in USPS possession.

Package was delivered today.

Amazon show tracking that makes sense. Informed Delivery tells me this package is coming today. It came in. Tracking number is correct.

USPS.com tells me the packaged was delivered on Fab 1 in South Carolina.

I assume Amazon had another way to query the USPS database, and informed delivery emails are correct, but the Web Interface for USPS Tracking is probably broken and query a corrupt database.

I haven't seen anything like this before.
