USPS Shipping Considerations

There is so much that goes into choosing a shipping carrier. For a smooth shipping process, you will want to make sure the carrier you choose for your business offers services that align with your business needs and make shipping accessible and efficient.

When it comes to shipping with USPS, we will break down these shipping considerations:

  • Shipping services
  • Speed of delivery
  • Size and weight requirements
  • International shipping options


No matter which carrier you decide to use as a shipping provider, these shipping considerations should be carefully weighed. Consider making a chart of the shipping offerings and services relevant to your business and then seeing how each carrier stacks against it. You can also rate which factors are most important to you to help narrow down the decision. With USPS, shipping services have expanded to suit small businesses and ecommerce companies better. USPS' Priority Mail services are on par with other big delivery services and are what we will focus on with this carrier. No matter the size of your business, there is a delivery service that is suited for you and your business. 


USPS Service Offerings

One of our ship tips is to reconsider your current shipping offerings to save money and provide your customers with a better shipping experience whenever they purchase your products. For your ecommerce business needs, USPS offers a variety of shipping services. With low costs and speed of delivery being top of mind for the customer, these are three excellent options to consider when shipping with USPS, all of which are Priority Mail:

  • Flat rate shipping
  • Priority mail regional rate
  • Priority Mail Express


Priority Mail flat rate boxes are excellent for packages that will consistently fit into the flat-rate packaging. Flat rate boxes are a less expensive option for small but more substantial items traveling farther distances. With flat rate boxes, your pricing will not fluctuate, regardless of the weight of your package. In contrast with flat rate boxes, USPS also offers Priority Mail regional rates determined by both the destination and package size. These options have varying but much smaller weight restrictions. Regional rate offerings are optimal for businesses that ship nearby instead of longer distances. 


Size and Weight Requirements

When it comes to calculating shipping costs, your packaged products' weight and size play a considerable role in determining the right shipping option. With USPS flat rate envelopes and boxes, varying shipping costs are not a concern. When shipping with flat rate boxes, you cannot exceed 70 pounds for the final package weight, and there must be a maximum combined length and girth of 108 inches. There are different packages for flat rate shipping, so you can choose an optimal option for the type of products that your business sells. The regional rate boxes must not exceed 15-20 pounds, depending on which type of box you use.

If flat rate boxes don't fit the bill, there are plenty of size options available with poly mailer bags from Shop4Mailers. These mailer bags are made of a lightweight and durable plastic material, yet will withstand any punctures, tears, and holes that may occur during transit. No matter your shipping needs, we can help you find the right mailer for your business. Regardless of what type of package you use, USPS can help you determine how to size your parcels with this guide to ensure you are getting the best value.


Speed of Delivery

With speedy delivery services, USPS can compete with big-name delivery services, especially when it comes to their Priority Mail options. The great thing about Priority Mail services is the speed of delivery, which we will dive into later. All of USPS’ Priority Mail services deliver within 1-3 days. A shipping tip we love is predetermining the cost and timing of your delivery before sending it off.

There are three USPS delivery options that we will cover here:

  • Retail Ground
  • First-Class Mail
  • Priority Mail Express


These three shipping services give excellent options depending on the urgency of your delivery needs. The retail ground offers shipping services within 2-8 days, which is the slowest option but an excellent offering for larger packages. First-class mail offers services within 1-3 days, which is similar to priority mail shipping except for pack size and weight requirements are much smaller. This option is ideal for small, lightweight shipments in which products can fit in envelopes or small packages. Lastly, Priority Mail Express shipping offers guaranteed overnight delivery and is the fastest shipping service offered by USPS. No matter which option you choose, all packages come with USPS tracking for you and your customers. These options are great for domestic shipping, but in the case of international shipping, USPS has services that cover that too.


Delivery Destination

USPS offers international shipping with Global Express Guaranteed, Priority Mail Express International, Priority Mail International, and First-Class International Mail and Package services. Like domestic shipping services, you should consider size and weight, speed of delivery, tracking, and insurance when choosing an international shipping service with USPS. You can easily compare which international service fits best with your business needs here.
