overnight delivery service

overnight delivery service refers to a shipping option that guarantees delivery of a package by the next business day. Major carriers such as USPS, UPS, and FedEx offer overnight delivery services, each with varying pricing, coverage, and delivery times. USPS offers Priority Mail Express for overnight deliveries, while UPS and FedEx provide services like UPS Next Day Air and FedEx Priority Overnight. These services are ideal for urgent shipments that need to arrive quickly, such as legal documents, medical supplies, or perishable items. While overnight delivery is faster, it is also more expensive than standard shipping methods.
