The U.S. Postal Service is set to introduce a next-day shipping service called Next Day Priority this year, aimed at retail and online businesses. This service will allow packages to be delivered overnight to locations within 150 miles of processing centers, covering approximately 87% of the U.S. daily. The Postal Service is seeking shippers who can meet specific volume and cutoff requirements. Additionally, the agency is enhancing its Ground Advantage service for cost-effective shipping and expanding its USPS Connect offerings to include same-day and next-day delivery options for small and mid-sized shippers.
