The United States Postal Inspection Service (or USPIS) is the law enforcement arm of the United States Postal Service. Its jurisdiction is defined as "crimes that may adversely affect or fraudulently use the U.S. Mail, the postal system or postal employees." The mission of the U.S. Postal Inspection Service is to support and protect the U.S. Postal Service, its employees, infrastructure, and customers by enforcing the laws that defend the nation’s mail system from illegal or dangerous use.

An agency with approximately 4,000 employees, 1,200 criminal investigators, an armed uniformed division with 1,000 personnel, forensic laboratories and a communications system, and with 1,000 technical and administrative support personnel, the USPIS leads and assists in numerous joint federal and state investigations.

The Postal Inspection Service has the oldest origins of any federal law enforcement agency in the Special Agent. In 1830, the Special Agents were organized into the Office of Instructions and Mail Depredations. The Postal Inspection Service was the first federal law enforcement agency to use the title Special Agent for its officers. Congress changed this title to Inspector in 1880.

For some time, one of their primary duties was the enforcement of obscenity prohibitions under the Comstock Act.

Jurisdiction and activities

As fact-finding and investigative agents, Postal Inspectors are sworn federal law enforcement officers who carry firearms, make arrests and serve federal search warrants and subpoenas. Inspectors work closely with U.S. Attorneys, other law enforcement agencies, and local prosecutors to investigate postal cases and prepare them for court. For example, on all international mail Postal Inspectors work closely with U.S. Customs and Border Protection (CBP) or U.S. Immigration and Customs Enforcement (ICE) while on domestic mail Postal Inspectors work closely with state and local law enforcement agencies. There are approximately 1,200 Postal Inspectors stationed throughout the United States and abroad who enforce more than 200 federal laws covering investigations of crimes that adversely affect or fraudulently use the U.S. Mail and postal system.

The USPIS has responsibility to safeguard over 600,000[2] Postal Service employees and billions of pieces of mail transported worldwide yearly by air, land, rail and sea.

USPIS was at one time the only investigative agency of the Postal Service; however, with the creation of the USPS Office of Inspector General in 1996, they assumed many duties previously carried out by the USPIS. The USPS OIG conducts independent audits and investigations. Audits of postal programs and operations help to determine whether the programs and operations are efficient and cost-effective. Investigations help prevent and detect fraud, waste, and misconduct and have a deterrent effect on postal crimes.

The OIG primarily took over the Postal Inspection Service's audit function, as well as fraud (against the USPS) waste and abuse.

Since the September 11, 2001, attacks, the USPIS has also investigated several cases where ricin, anthrax and other toxic substances were sent through the mail. Although the USPIS has a wide jurisdiction, USPIS investigations can be categorized into these seven types of investigative teams and functions:

  1. Fraud: These types of investigation involve crimes that use the mails to facilitate fraud against consumers, business and government. Federal statutes that surround these types of investigations include, mail fraud, and other criminal statutes when they are tied to the mails such as bank fraud, identity theft, credit card fraud, wire fraud, and Internet/computer fraud. Mail fraud is a statute that is used in prosecuting many white collar crimes, this would include, [4] on mail fraud charges.Otto Kerner McGee is credited with assisting in the conviction of former Illinois Governor [3]
  2. External Crime & Violent Crime Teams: The External Crimes Function of USPIS is a function that investigates any theft of US mail by non employees, assaults of postal employees and theft and robberies of postal property. This function also investigates robberies of postal employees and postal facilities, burglaries of postal facilities, and assaults and murders against postal employees. This investigative function focuses on ensuring that the sanctity and trust in the U.S. Mail system is maintained.
  3. Prohibited Mailing Investigations: Prohibited mailing investigations are USPIS investigations that focus on the prohibited mailing of contraband including: narcotics, precursors and proceeds; child pornography and other sexually prohibited materials; and hazardous materials to include, mail bombs, and nuclear, biological and chemical weapons. The laundering of narcotics and other criminal proceeds through the use of Postal Money Orders are sometimes categorized under this investigative function.
  4. Aviation and Homeland Security: USPIS investigations also include the securing and protecting of transportation of US Mail and any risk that might compromise the security of the homeland because of these mails. Security Audits are conducted by these teams to ensure that postal service maintains facilities secure from not only theft and robberies but also natural and manmade disasters.
  5. Revenue Investigations: USPIS investigates cases where fraudulent practices are conducted by business and consumers that mail items without proper postage or with counterfeit postage and indicia or crimes that defraud the USPS of revenue.
  6. International Investigations and Global Security: This investigative function ensures that international mail is secured and any international business decisions and campaigns remains safe, and secure. USPIS maintains investigators in the US and in posts around the world for protection, liaison, and intelligence.
  7. Joint Task Force Investigations: USPIS participates in joint task force investigations where laws applicable to the mail service are involved. These cases are often wide ranging and involve every law enforcement agency of the Federal Government. For example, USPIS participated in the largest count indictment and conviction in NASA history, the Omniplan case, that put seven companies out of business and ended with the conviction of Omniplan owner, Ralph Montijo, on 179 federal crimes.[5][6]

The Postal Inspection Service operates one main forensic crime laboratory that is staffed by forensic scientists whose expertise includes the examination of physical and digital evidence. The crime laboratory also has several satellite offices across the country whose primary mission is computer forensics. The Postal Inspection Service's Technical Services Unit (TSU) provides investigative support through the use of new technology and the operations of two national communication centers known as the National Law Enforcement Control Centers or the "NLECC". In 2003 U.S. Immigration and Customs Enforcement renamed their national communication center, previously known as "Sector" to the "National Law Enforcement COMMUNICATIONS Center" also known as "NLECC", USPIS NLECC and ICE NLECC are two independent federal law enforcement radio communications centers but coincidentally share the same acronym and an almost identical name.

Police Force

To assist in carrying out its responsibilities, the Postal Inspection Service maintains a Police Force staffed by approximately 500 uniformed Postal Police Officers who are assigned to critical postal facilities throughout the country. The officers provide perimeter security, escort high-value mail shipments, and perform other essential protective functions. These uniformed officers provide a visible deterrent at postal facilities located primarily in urban high-crime areas and respond to emergencies including disturbances, assaults, theft, robberies and other incidents threatening the safety of postal employees and customers. They make arrests for crimes committed against the United States Postal Service and felonies committed in their presence. These employees are required to qualify with agency-issued shotguns and their assigned sidearms and are designated as police officers under Title 18, Part 2, Section 3061(c)

USPIS Academy

The Postal Inspection Service maintains a law enforcement academy (the Career Development Unit (CDU)) based in Potomac, Maryland. It is a federally accredited law enforcement academy by the Federal Law Enforcement Training Accreditation (FLETA).[7]

Fallen Officers

Fourteen US Postal Inspectors and Postal Police Officers have died in the line of duty.[8] Their names have been etched on the National Law Enforcement Officers Memorial wall and to a Postal Inspection Service plaque at the agency's national headquarters, both located in Washington, D.C.


In 2006 the Postal Inspection Service created the "2 SMRT 4U" campaign aimed at teenage girls, the group most targeted by child exploitation, the United States Department of Justice honored the Postal Inspection Service with its Internet Safety Award.[10]
