General Crimes

General crimes include Postal Service employees’ misuse of Postal Service computers, destruction or theft of Postal Service property, falsification of official documents and forgery, theft of funds, abuse of authority, sabotage of operations, narcotics use or sale of drugs while on duty, and alcohol abuse.


Internal Mail Theft


The overwhelming majority of Postal Service employees work conscientiously to move the nation’s mail to its proper destination. Unfortunately, a small number of employees abuse the public’s trust by delaying or stealing the mail. It is the job of OIG special agents to identify dishonest employees and take proper investigative steps to have them prosecuted and removed from the Postal Service.


Financial Fraud

Embezzlements may involve Postal Service employees stealing money from cash drawers, using sophisticated schemes to manipulate postal money orders or money order funds, or falsifying financial retail records. When post offices experience unusual or significant shortages, OIG special agents employ various investigative techniques to uncover embezzlements.

Contract Fraud


The Postal Service manages billions of dollars in contracts, ranging from multi-million dollar national contracts for services such as transportation networks and IT infrastructures, to local contracts at individual postal facilities. The sheer volume of contracts and the huge dollar value provide opportunities for contractors and employees to defraud the Postal Service.

Introduction to Contract Fraud – False Claims and Statements

Contract fraud is a big problem for the federal government and quite possibly for the U.S. Postal Service, which currently manages over 20,000 contracts worth $29 billion. Conservative business estimates project up to 5 percent of contracted dollars are lost to fraud, meaning $1.45 billion of Postal Service funds are potentially at risk.
