To protect the mail and to maintain the integrity of postal processes and personnel, the U.S. Postal Service relies on the investigative efforts of Office of Inspector General (OIG) special agents. These special agents – federal law enforcement officers – are charged with maintaining America’s confidence in the integrity of the Postal Service.

Investigative efforts, coupled with the OIG’s objective and independent audits, promote the efficiency, effectiveness, and integrity of America’s postal system. OIG special agents investigate internal crimes and frauds against the Postal Service. These efforts contribute to safeguarding the Postal Service’s revenue and assets and help deter postal crimes, ultimately helping to maintain a stable and sound Postal Service. Special agents stationed in 100 offices nationwide conduct investigations in the following program areas:

  • Contract Fraud
  • Financial Fraud
  • Healthcare Fraud
  • Internal Mail Theft
  • Official Misconduct
  • Technical Investigations
  • Special Inquiries
  • Whistleblower/Reprisals

Special agents also investigate bribery, kickbacks, extortion, conflicts of interest, and allegations against Postal Service executives. In addition, the Office of Investigations combats fraud and theft through the Countermeasures Directorate’s crime prevention efforts.
