Ideal for small and lightweight shipments under 1 lb.
USPS (United States Postal Service)
The USPS has long been the backbone of American delivery, reaching virtually every address in the country — including the most rural and remote areas as well as US Military Bases near and far. While new carriers have entered the market, USPS remains a key player for lightweight parcels and cost-efficient delivery to any ZIP code.
