A parcel service is a company that specializes in the delivery of packages and goods from one location to another. These services can handle various types of shipments, including letters, boxes, and larger freight items. They often provide tracking options, allowing customers to monitor their parcels during transit. Many parcel services operate locally, nationally, or internationally, catering to both individuals and businesses. Well-known examples include UPS, FedEx, and DHL. These companies typically offer different delivery speeds, such as standard or express, to meet the needs of their customers.
