USPS handles an estimated 1.5 to 2 billion Amazon packages annually, representing about 30% of USPS total package revenue. Losing this volume is a structural blow to USPS finances
The USPS 8% surcharge announced days later is partly a response to losing Amazon's massive volume. FBM sellers using USPS effectively subsidize the gap Amazon left behind

What's Happening

Amazon is pulling at least two-thirds of its parcel volume from USPS before the current delivery contract expires in October 2026. The Wall Street Journal first reported the volume cut on March 17, and Reuters, CNBC, and The Hill all confirmed the move within 48 hours.

We treat this category of update as priority intake because it propagates into seller-level dashboards immediately.

This isn't a negotiation tactic. Amazon has already started rerouting packages through its own delivery network (AMZL) and contracted carriers like UPS. USPS Postmaster General Louis DeJoy told Congress that Amazon "walked away at the eleventh hour" from contract renewal talks. The USPS considers Amazon its single largest package customer, handling an estimated 1.5 to 2 billion Amazon parcels annually.

For Amazon sellers, this shift has real consequences. Delivery routes, transit times, and last-mile coverage are changing. Rural customers who relied on USPS as the primary delivery carrier may see longer delivery windows. And the USPS 8% surcharge Announced days later is partly a response to losing Amazon's volume and the revenue it generated.

Current USPS-Amazon delivery contract

To put this in perspective, Amazon accounted for roughly 30% of USPS's total package revenue According to Digital Commerce 360's analysis. Losing two-thirds of that volume means USPS is about to lose approximately 20% of its package business from a single decision.

Amazon's internal delivery network (AMZL) now covers over 72% of US last-mile deliveries. The company has invested $100+ billion in logistics infrastructure since 2019. Cutting USPS volume is the natural next step in Amazon's push to control the entire fulfillment chain from warehouse to doorstep.

How This Affects Amazon Sellers

Rural Delivery Times May Increase

USPS has the most extensive rural delivery network in the US, reaching every address six days a week. Amazon's own network (AMZL) is strong in metro areas but thinner in rural zones. Customers in rural areas may see delivery windows stretch from 2-3 days to 4-5 days. This could affect your seller metrics if you sell products popular in rural markets.

FBM Sellers Face Higher USPS Rates

The 8% USPS surcharge is a direct consequence of Amazon pulling volume. With less revenue from Amazon, USPS raises prices for everyone else. FBM sellers who ship via USPS are subsidizing the gap Amazon left behind. This makes the FBA vs FBM cost comparison shift toward FBA for many product categories.

FBA Gets Relatively More Competitive

As USPS rates go up and Amazon's own delivery network expands, FBA's cost-per-delivery improves relative to FBM. Amazon is building an ecosystem where using its own fulfillment becomes the most economical option. Even with the 3.5% FBA fuel surcharge, FBA will be cheaper than FBM + USPS for most standard-size products.

Multi-Channel Fulfillment (MCF) Implications

Amazon's MCF service, which fulfills non-Amazon orders using FBA inventory, becomes more attractive as USPS costs rise. If you sell on Shopify, eBay, or your own store, MCF's preferred pricing may now undercut USPS-based fulfillment for many product sizes. The tradeoff: you're deeper into Amazon's ecosystem.

What You Should Do Now

1.
Run an FBA vs FBM cost comparison with updated rates
The math has changed. With USPS rates up 8% and Amazon's fuel surcharge at 3.5%, recalculate which fulfillment method is cheaper for each product. Use Nova's P&L Dashboard to compare per-unit contribution margins across fulfillment channels.
2.
Monitor delivery performance metrics closely
As Amazon transitions away from USPS for last-mile delivery, watch your Buy Box eligibility and delivery promise accuracy. Late deliveries during the transition period could trigger seller metrics issues. Track your daily performance for any delivery-related complaints.
3.
Consider consolidating into FBA for your core catalog
Amazon is building an ecosystem where FBA is the most cost-effective and reliable fulfillment option. If you're split between FBA and FBM, April 2026 might be the inflection point to shift more SKUs into FBA. Identify your top-revenue FBM products and model the cost of switching them.
4.
Diversify carrier options for non-Amazon channels
If you sell on Shopify, eBay, or your own store, explore UPS, FedEx, and regional carriers. The USPS surcharge makes UPS Ground more competitive for packages over 1 lb. Also evaluate Amazon MCF as an alternative fulfillment option for non-Amazon orders.
5.
Assess your rural customer exposure
If a significant portion of your sales go to rural ZIP codes, monitor delivery times closely over the next few months. Consider adjusting delivery promises or listing strategies for products heavily bought in rural areas. Use Custom Breakdowns to segment performance by geography if your data supports it.
