What it is
The Inspection Service states its mission as supporting and protecting the Postal Service, its employees, infrastructure and customers; enforcing the laws that defend the mail system from illegal or dangerous use; and ensuring public trust in the mail. What makes it worth listing is the shape of its jurisdiction: it is defined by a medium rather than by a territory or a category of offence, so the same body investigates fraud, theft, and the movement of prohibited items, joined only by the fact that the mail was used.
What it covers
The United States postal system — its employees, facilities and the mail itself — rather than a bounded territory.
Broad responsibilities
- Investigation of crime involving the mail
- Protection of postal employees and facilities
- Enforcement of the federal laws protecting the mail system
Who it answers to

SCOPE: the United States Postal Inspection Service only. The service's own about page, read directly. Supports the official name and the service's own statement of mission: supporting and protecting the U.S. Postal Service, its employees, infrastructure and customers, enforcing the laws that defend the mail system, and investigating crime that involves the mail. The page states a number of federal laws enforced and a workforce figure; neither is published as a fact about the present.
