USPS Service Offerings

USPS offerings come in five different categories and each category is designed to fit different individual and business needs. These offerings are as follows:

  • Priority Mail Express: This is the fastest among USPS's various domestic mail offerings. With the Priority Mail Express service, vendors can be sure of their customers receiving their packages overnight. It's designed for time-sensitive deliveries and works seven days a week.
  • Priority Mail: With this shipping option from USPS, recipients get delivery of their packages within 1-3 business days, with delivery being most impacted by shipping and delivery points. It features flat-rate options for items weighing below 70 lbs.
  • First Class Mail: This is an affordable mail service that is designed specifically for single-piece and standard-sized envelopes weighing approximately 3.5 oz and large envelopes/small packages that weigh approximately 13 oz or less. A scheduled delivery is usually within 1-3 business days.
  • Retail Ground: This is a reliable means of shipping oversized packages, especially those that are not urgent. The service is economical and a good option for vendors who ship larger packages that surpass the weight restrictions of Priority Mail and Priority Mail Express.
  • Media Mail: This option is for those who are looking for a cost-effective means of sending media and other educational materials. However, you should take note that there are restrictions on the types of media that can be shipped using Media Mail. Some of the items that can be shipped include video/audio recordings, books, printed test materials, printed music, printed educational charts, medical loose-leaf pages/binders, computer-readable media, and others. Delivery is usually between 2-8 business days, with a maximum weight of 70 lbs.

Why Choose USPS?

  • On-time delivery: When it comes to on-time delivery, whether it is USPS First Class vs Priority, you can be sure of your customers not being disappointed. USPS makes sure that the parcels or packages are delivered within a timely period.
  • Flat-rate charges: With USPS Priority shipping services, you can use flat rate boxes for your shipments. Using flat rate boxes, shipments are prices per box size and means that you only have to pay one price as long as it weighs 70 lbs or less. So, for small or heavy items that need to be shipped long distances, this can be a great value for money option for you. Learn more about flat rates.
  • Cubic rates: For Priority Mail shipments under 0.5 cubic feet, USPS charges based on the size of the parcel rather than the weight. This means that if your parcel is weighty but not large, you can make some big savings (often even better than flat rate boxes). Easyship offers and pre-calculates the cubic rate for you (many shipping platforms don't) ensuring that you get the lowest USPS pricing on your shipments.
  • Multiple international delivery choices: To make shipping as stress-free as possible for vendors, USPS's international shipping services has four offerings that make deliveries to over 180 countries. The choice you make depends on your delivery timeline.
  • Availability of extra services: USPS offers customers a wide range of extra services which includes free package pickup and free boxes and envelopes for packages/parcels. For the free pick up, there are conditions that in order for it to be free, there should be at least one package using any of the USPS expedited services, such as First Class, Priority Mail, or Priority Mail Express. The service also offers free shipping labels for envelopes and boxes.
  • Tracking services: USPS now offers users of both its domestic and international mailing services useful tracking. From acceptance of the package at the postal facility to delivery at the residential address or post office, intermittent tracking offerings allow users to check delivery progress online, through phone calls, or text.
