How often can a Pen register, trap and trace, TIID, or MCTI be extended?

The correct understanding of how often a Pen register, trap and trace device, traditional interception device (TIID), or multi-channel transmission interceptor (MCTI) can be extended is grounded in the legal framework governing electronic surveillance. Specifically, under federal law, such as the Electronic Communications Privacy Act (ECPA), these devices can indeed be extended for an unlimited number of times, provided that each extension follows due process and is justified accordingly.

The process requires law enforcement to demonstrate a continued need or relevance for the information being collected. Each extension request must be appropriately submitted and approved, but there is no statutory limit on the number of times extensions can be requested as long as they meet legal standards. This flexibility allows for ongoing investigations when necessary.

In the context of this question, the choice reflecting that extensions can be granted an unlimited number of times is correct. Understanding this allows for proper compliance with legal protocols when monitoring communications for investigative purposes.
