postal vs courier is a comparison between two methods of delivering mail and packages. Postal services, such as USPS, rely on national and local government infrastructure to process and deliver items. They are typically more affordable and offer a variety of delivery options, including standard mail, express services, and international shipping. Couriers, such as UPS, FedEx, and DHL, are private companies that offer expedited, often more reliable services, especially for time-sensitive deliveries. Couriers are known for their faster delivery times, real-time tracking, and specialized services. The choice between postal services and couriers depends on factors like budget, delivery speed, and the destination of the package.
