Quick Look at the Highlights
Let me give you the quick answer: Amazon makes more money, but USPS touches more addresses. "Bigger" depends entirely on the yardstick you pick. After digging through financial statements, delivery data, and years of hands-on shipping experience, I'm here to break down every angle.
Defining "Bigger" for Amazon and USPS
When someone asks "Who is bigger, Amazon or USPS?", they usually mean one of three things: revenue, headcount, or package volume. But there's a fourth dimension that rarely gets attention—physical network size. The truth is, both companies are massive, but their bigness shows up in completely different ways.
I've spent over a decade in the logistics space, and I've seen e-commerce sellers obsess over choosing between these two. They're not really competitors in the traditional sense—Amazon is a retail monster, while USPS is a government-appointed postal service. But they do intersect in package delivery, which makes the comparison fascinating.
Amazon vs USPS: Who Has More Revenue?
No surprises here. Amazon's annual revenue blows USPS out of the water. Based on Amazon's latest 10-K filing, the company pulls in well over $500 billion a year. USPS, on the other hand, generates around $80 billion in revenue. That's a massive gap—roughly six times bigger.
But hold on. Revenue alone doesn't tell the full story. USPS operates under a strict mandate to serve every American address at affordable prices. Amazon doesn't have that obligation. So while Amazon's revenue is higher, USPS's revenue model is fundamentally different—it's not designed to maximize profits.
I've had clients ask me whether it's fair to compare these two side by side. My honest take: it's not apples-to-apples. But that doesn't make the comparison useless. It highlights how two organizations can be "big" in completely divergent ways.
Employee Count: Who Has More Workers?
If you count total employees, Amazon is the clear winner. Amazon employs over 1.5 million people globally, making it one of the largest private employers on the planet. USPS employs roughly 640,000 career employees, though that number swells with seasonal staff.
Here's a surprising twist: USPS actually has more delivery drivers and processors in the United States than Amazon. That's because USPS has to cover every zip code, while Amazon can centralize its workforce in high-density areas. I remember touring a USPS sorting facility—the sheer number of workers focusing on last-mile delivery was staggering.
Who Delivers More Packages: Amazon or USPS?
This is where USPS shines. According to the latest parcel shipping index, USPS delivered roughly 7.6 billion packages in a year, while Amazon Logistics handled about 6 billion. So USPS still takes the crown when it comes to pure package volume.
But here's the nuance: Amazon Logistics mostly handles its own e-commerce packages, while USPS delivers for everyone—including Amazon. In fact, Amazon still relies on USPS for final-mile delivery in many rural and remote areas. That reliance is a dirty little secret in the industry.
I've seen this firsthand. A friend runs a small specialty shop in Montana. He ships via USPS because Amazon's delivery network simply doesn't reach his customers' cabins. For him, USPS isn't just "bigger"—it's the only option.
Infrastructure Reach: Why USPS Has the Widest Net
If we're talking about physical footprint, USPS is unrivaled. It operates around 34,000 post offices and retail locations, and more than 230,000 vehicles—including those iconic mail trucks. Amazon has an impressive network of fulfillment centers and vans, but it doesn't get close to USPS's universal coverage.
Consider this: USPS delivers to every address in the United States, including remote islands and mountain cabins. Amazon can't legally do that, nor would it be profitable. That's why USPS is indispensable despite its financial challenges.
A common rookie mistake is assuming Amazon's huge warehouses make it "bigger" in delivery infrastructure. But when it comes to sheer reach, USPS wins easily. Amazon might have the bigger buildings, but USPS has the broader map.
Why Should You Care Which One Is Bigger?
For e-commerce sellers, casual shoppers, and investors, the size comparison has direct implications:
For shipping decisions: If you're sending products to customers, USPS often offers cheaper rates for lightweight parcels, especially to residential addresses. Amazon's delivery network is faster in metro areas but less reliable in rural zones. Knowing this can save you money and heartaches.
For investors: Amazon's size translates into massive market valuation and growth potential. USPS, as a federal agency, doesn't have stock you can trade, but its health affects the broader economy. Investors sometimes overlook that when they analyze shipping-related stocks.
For consumers: Understanding the difference helps you set expectations. If you're buying from Amazon, you might get package-level tracking through Amazon Logistics. If the seller ships via USPS, you may see classic USPS tracking updates. It's a minor thing, but it helps to know who's handling your stuff.
I always tell people: "Bigger" isn't always better. Amazon is financially powerful, but USPS has a monopoly on universal service. The next time you complain about USPS delays, remember they're carrying a burden no private company would accept.
Frequently Asked Questions
This comparison isn't about picking a winner. It's about appreciating scale. Amazon's bigness is measured in dollars and influence. USPS's bigness is measured in coverage and obligation. For anyone working in e-commerce or investing in shipping infrastructure, that distinction matters more than you think.
