USPS strives for 100% accuracy, but when you deliver 40% of the world's mail volume,
150+ billion pieces per year to 150+ million US addresses,
a small percentage of items are sometimes misdirected and therefore delayed.

Most people don't understand the scale of 150,000,000,000.
Consider that those pieces are delivered over 304 days = 493,421,052 pieces of mail a day average (accounting for the Sundays and holidays). I cannot recall a time when something was lost. I've had the odd package misdirected and then re-directed.
By comparison, I fly about 5 times a year. That's maybe 200 times in my life. My luggage has been lost thee times, once never to be found again. And many of those trips I only take carry-on luggage.
The two times my luggage was found, it was returned to me at the airport as I was departing for my return flight.
