overnight package usps

overnight package usps is a shipping service provided by the United States Postal Service that guarantees delivery of a package by the next business day. USPS offers two primary options for overnight delivery: Priority Mail Express, which is the fastest service, and First-Class Mail for smaller, lighter packages. Priority Mail Express includes tracking and delivery by 10:30 AM or 3 PM depending on the destination, and it comes with a money-back guarantee if not delivered on time. USPS offers this service for both domestic and international shipping, though the price will vary based on package size, weight, and destination.
