Mail cover is a surveillance tactic that involves monitoring and recording the mail of a target individual or organization. This can include both physical mail and digital mail, such as email.
The use of mail cover can be done for a variety of reasons, including to gather evidence for a criminal investigation or to monitor the activities of a suspect. The government has the authority to conduct mail cover under the Electronic Communications Privacy Act (ECPA) of 1986.
Mail cover can be invasive and can raise concerns about privacy and civil liberties.
What is Mail Cover
Mail cover is a law enforcement investigative technique used by the United States Postal Service to record information from the outside of letters and parcels before they're delivered.
The Postal Service grants mail cover surveillance requests for about 30 days and may extend them for up to 120 days.
Mail covers can be requested to investigate criminal activity or to protect national security, with the Postal Service granting around 15,000 to 20,000 criminal activity requests each year.

It rarely denies a request, which has led to criticism from some who are concerned about the delay in mail the process might cause.
Mail cover is defined by the U.S. Postal Regulations 39 CFR 233.3 and the Internal Revenue Manual as a process that does not involve reading the mail, but only gathering information on the outside of the envelope or package.
The number of mail covers has increased over the years, with 9,022 in 1984 and 14,077 in 2000.
Program Details
Mail cover is a surveillance technique used by law enforcement agencies to gather information about a person's mail activities.
The program was first authorized by the US Congress in 1976, as part of the Foreign Intelligence Surveillance Act.
Mail cover involves monitoring a person's mail, both incoming and outgoing, without opening or tampering with the mail itself.
The FBI has been known to use mail cover to investigate a wide range of crimes, including terrorism, espionage, and organized crime.
A mail cover can be initiated by a law enforcement agency with a court order or a warrant, but in some cases, it can be done without one.
The FBI has a specific form, called a "mail cover", that is used to request and document mail cover surveillance.
The form includes information about the target, the reason for the surveillance, and the duration of the surveillance.
Mail cover surveillance can be conducted for a maximum of 30 days, after which it must be renewed with a new court order or warrant.

Concerns and Implications
Mail cover can be a serious concern for individuals and organizations, especially those in sensitive fields like law enforcement or journalism.
The implications of mail cover can be far-reaching and potentially devastating, as seen in cases where sensitive information is compromised.
The FBI's mail cover program is a prime example of the potential risks, with the agency collecting and analyzing millions of pieces of mail each year.
Mail cover can also be used to gather intelligence on individuals and groups, often without their knowledge or consent.
This can lead to a chilling effect, where people are reluctant to express their opinions or engage in activities for fear of being monitored.
The use of mail cover raises important questions about privacy and civil liberties, particularly in cases where it's used as a tool for surveillance.
Frequently Asked Questions
