The U.S. Postal Inspection Service is the law enforcement branch of the U.S. Postal Service, empowered by federal laws and regulations to investigate and enforce over 200 federal statutes related to crimes against the U.S. Mail, the Postal Service and its employees. Postal inspectors investigate any crime in which the U.S. Mail is used to further a scheme, whether it originated in the mail, by telephone or on the Internet. The use of the U.S. Mail is what makes it a mail fraud issue. If evidence of a postal-related violation exists, postal inspectors may seek prosecutive or administrative action against a violator; however, if money is lost to a fraudulent scheme conducted through the mail, inspectors do not have the authority to ensure you are refunded your loss and cannot require that products, services or advertisements, on the Internet or elsewhere, be altered.
