What postal service is often used for priority delivery?

When considering postal services that are designed for priority delivery, Priority Mail by the United States Postal Service (USPS) stands out as a key option. This service is specifically tailored to provide time-sensitive delivery, typically offering delivery within 1 to 3 business days depending on the destination. Priority Mail is popular because it not only guarantees faster delivery compared to standard services but also includes benefits such as tracking, insurance coverage for loss or damage, and the possibility of using flat-rate boxes, which can be cost-effective for shipping various items.

The other options, while they may offer expedited services, do not specifically identify with a USPS product designed for priority time-sensitive delivery. For example, while Express Mail by FedEx, Overnight Shipping by DHL, and Standard Delivery by UPS may provide speedy services, they are not directly associated with the USPS priority delivery framework that includes established timeframes and pricing options specifically for mail processed by the postal service. Thus, Priority Mail is recognized as the service most aligned with priority delivery needs in the context of USPS offerings.
