USPS Shipping

Couriers

USPS shipping refers to parcel delivery services provided by the United States Postal Service, both within the U.S. and internationally. Depending on the service selected, USPS offers different delivery speeds, packaging types, and price points. These services are often used by individuals and businesses to send letters, packages, and merchandise across the country or abroad.

Ship24 allows you to track any USPS shipment using just the tracking number, without needing to know which service or location it's associated with.

USPS Shipping: Flat Rate, Regional, and More

Depending on the size and weight of your item, USPS offers different pricing models:

  • Flat Rate: Same price regardless of weight or distance, as long as it fits in the USPS-branded box.
  • Weight-Based: Pricing depends on actual or dimensional weight and the distance it travels.
  • Regional Rate: Available for certain boxes with pricing based on delivery zones (available online only).

Flat Rate shipping is ideal for heavier items that can fit inside small or medium boxes, while Regional and Weight-based options are better for non-standard sizes.
