EXPLANATORY NOTE 
Prank callers are, in a word, obnoxious. Thousands of people are bothered by one form of 
prank caller or another every day. Prank calls range from annoying hang-ups to false calls to 
emergency services or bomb threats. Some prank calls may even waste the time and resources of 
emergency services. Although prank calls may easily be traced through Caller ID, most 
telephone companies permit callers to withhold the identifying information from calls. 
This bilI prohibits local exchange telecommunications companies from offering services 
which allow the blocking of information from caller identification devices including per-call 
blocking and per-line blocking in order to identify the caller's identification number and 
minimize the number of prank callers. I 
I This bill was originally filed in the Fourteenth Congress, Second Regular Session
