Postal Service

The Postal Service subsector includes the activities of the National Post Office and its subcontractors operating under a universal service obligation to provide mail services, and using the infrastructure required to fulfill that obligation. These services include delivering letters and small parcels. It has no schema of its own: companies here are mapped on the Transportation & logistics schema, and what it does not cover is recorded as gaps.
