A bill to amend title 18 of the United States Code to require court orders for the surreptitious use of pen registers, and for other purposes.

Amends the Federal criminal code with respect to the interception of communications to redefine "wire communication" and "intercept" to include the acquisition of the identity of the intended or actual point of origin or reception of a communication (thus applying such law to the use of a "pen register," a mechanical device which records the numbers dialed on a telephone line to which it is attached).
