The Amazon Project 2022-2025
This project is to monitor what percentage of on-time deliveries Amazon achieves on
my orders for home, organizations I volunteer at & work* in the
four years of 2022, 2023, 2024 & 2025. I was motivated years ago when Amazon
started shifting Prime deliveries to my home & work between various distribution
centers, and the delivery issues seemed to have taken a huge jump up.
Ironically, they often pass from an Amazon center close to my house to
another farther away before being placed on a delivery vehicle.
This web page is tracking all of my business and
personal Amazon orders, Prime & non-Prime. An on-time delivery is when Amazon delivers
all items in a given order on or before the date promised at the time the order
is placed†.
I am only tracking Amazon’s delivery date accuracy here, which tends to be about
90% year-after-year, and not the intraday accuracy, as they rarely hit their
initial delivery windows (< a few %). Unless the delivery was paid to have a specific delivery time-window at the time
of the order, a delivery is counted as "on time" if it arrives on the original
promised calendar date regardless of the time it arrives that day.
If an item was lost in transit ("Never Delivered") and
Amazon automatically reordered it, that reorder appears as a separate order in
the list and is held to the new order's original promised delivery date.
Note that when Amazon uses an "Amazon Flex" driver, they mark the package as "Shipped" when the
delivery appointment has been scheduled, not when it's actually is given to the
courier.
What is NOT included:
Starting in March 2025, Amazon started listing walk-in in-store Whole Foods
Purchases (normal in-person grocery shopping) under my Amazon Prime orders in my
Amazon account. Those are not included below. Only online orders where Amazon
was responsible for delivery to my house or place of work are included below.
As of the last update on
January 3, 2026, 2025, covering 1713 orders for work & personal use over
those four years, Amazon's on time delivery rate
on my orders was
approximately 91.6%.
* An attempted delivery on or before the promise date but when the
business is closed counts as an on-time delivery. So does a USPS attempted
delivery on or before the promise date but when mail delivery is on a hold.
† Unless the delivery was
paid to have a specific delivery time-window at the time of the order, a
delivery is counted as "on time" if it arrives on the original promised calendar
date. If Amazon changed the promise
date after the order is submitted, the original promise date at the time of
order submission is used as that original promise date is, like price, part of
the bargain they proposed to entice me to submit the order with them as opposed
to one of their competitors like Walmart.
