Factors Affecting USPS Weekend Deliveries

Several factors can impact whether or not a seller’s package reaches your customer on a Saturday or Sunday. You can be a seller using USPS for FBM (Fulfilled by Merchant) for Amazon business, or use FBA, where Amazon signs a contract for weekend delivery. Still, the factors causing the delay are commonalities. 

Let’s take a look. 

1. Weather disruptions: Adverse weather can cause delays in fulfillment, particularly in remote areas where the effects can be worse.
   
2. Prioritization of Amazon and express delivery: Sometimes local post offices prioritize express or Amazon FBA deliveries, potentially pushing other parcels, including your FBM delivery, to Monday.
   
3. Package volume during peak season: During peak seasons like Q4 or Prime Days, USPS prioritizes high-volume contracts like Amazon over standard FBM shipments.
   
4. Incorrect addresses: Typos in the shipping address, missing apartment numbers, or wrong ZIP codes can delay weekend delivery attempts.
   
5. Access issues: Gated communities or buildings without weekend access can result in missed or rescheduled deliveries.
   
6. Mail class: Only Priority Mail Express and Amazon-partnered deliveries are eligible for Sunday delivery. If you’re using standard Priority Mail for your FBM, your package may not go out until Monday, even if it’s scanned “In Transit” on Sunday.
   
7. Amazon warehouse routing (FBA-specific): If you’re shipping inventory to Amazon’s fulfillment centers via USPS, internal delays at intake docks or misrouted packages can also cause hiccups, regardless of USPS performance.
   

So if you’re a seller, always use USPS Priority Mail Express for urgent deliveries and double-check address formatting before purchasing your label.

Why is USPS beneficial for FBA or FBM sellers?

If you’re an Amazon FBA seller, it may think what’s the point of USPS in our selling journey as Amazon takes care of the fulfillment process. Amazon may have an elaborate network of infrastructure scattered across the world but USPS is an essential piece of Amazon’s last-mile delivery infrastructure. Especially for rural and suburban areas as USPS helps Amazon reach where they can’t— with added speed and efficiency. Here’s what USPS brings to the table. 

1. Reliable last-mile delivery for Amazon FBA with weekend fulfillment

Amazon often uses USPS to complete last-mile deliveries, particularly in suburban and rural areas where USPS already has existing routes. This reduces the cost and complexity for Amazon and benefits sellers with faster, more reliable customer delivery—even on weekends.

If a customer orders on Thursday night, USPS can deliver by Saturday in most cases which reduces lead times. Sellers offering weekend shipping experience better sales during high-demand seasons like Q4, or Prime Day.

2. Affordable delivery rates for FBM (Fulfilled by Merchant) sellers

For Amazon sellers handling their own fulfillment, USPS offers competitively priced shipping options like: Ground advantage(day-definite ground service for lightweight to midweight packages), first-class package (budget option for shipping lightweight parcels under 16 oz with delivery in 2–5 business days) and priority mail (superior service with 1–3 business day shipping and tracking plus $100 insurance).

3. Better inventory turnover

FBA sellers use Amazon’s “Just-in-Time” restocking approach, and the quicker USPS can deliver, the faster inventory levels adjust and replenish. This method works excellently for preventing stockouts and overstocking issues.

5. Competitive edge

In 2025, customer expectations have evolved. With express delivery being practiced all across, if your delivery system is efficient enough to spare you from wondering “does USPS deliver mail on Saturday” or even on a Sunday, you’re on the right track. 

Sometimes, ensuring a Sunday delivery can become a differentiator for your business. USPS helps Amazon sellers meet their deadlines without paying for FedEx pricing.

Final thoughts

Whether you’re an Amazon seller aiming to meet Prime shipping expectations or an everyday consumer waiting for a weekend delivery, knowing USPS’s weekend schedule is crucial. In Los Angeles, USPS provides consistent Saturday deliveries and limited but vital Sunday services—primarily for Amazon packages and Priority Mail Express. 

This expanded delivery schedule reflects USPS’s commitment to adapting to the evolving demands of ecommerce and modern shipping expectations. By understanding these options, businesses and consumers alike can plan better, ship smarter, and deliver faster—even on the weekend.
