How many 30-day extensions can be requested for a pen register or trap and trace device?

A pen register or trap and trace device is used by law enforcement to gather information about the communications of a target, specifically concerning telephone numbers dialed or received. According to federal law, a pen register or trap and trace device can initially be authorized for a period of 30 days.

The law allows for multiple 30-day extensions to be requested, provided that law enforcement can justify the need for continued surveillance. Each extension of 30 days must be supported by the same level of probable cause that justified the original request. Therefore, as long as law enforcement can meet the required legal standards, they may continue to request these 30-day extensions indefinitely, making it possible to monitor communications over an extended period.

This flexibility in extending the use of these devices is critical for ongoing investigations, allowing authorities to adapt their surveillance as necessary based on the developments in their cases.
