Industry: Postal Service

Establishments in the Postal Service industry primarily engage in the collection, transportation, and delivery of mail and packages. This industry provides services such as sorting and distributing letters, parcels, and other mailable items, often operating under a universal service obligation. The defining characteristic of this industry is its role in facilitating communication and commerce through a structured network of postal routes and facilities, distinguishing it from courier and express delivery services that focus on expedited and specialized delivery options.
