Section 91-A. Customer of record for telephonic blocking and restrictions on the removal of telephonic blocks to certain area codes

Where  access
  to  telephone  numbers in the 800 and/or 900 area codes has been blocked
  at the request of the customer of record to prevent  the  completion  of
  the  call  to  numbers  in  such  area codes, the customer of record may
  provide a personal password to be retained in the customer's record  for
  purposes  of  preventing  the  unauthorized  removal  of the request for
  blocking. No telephone corporation shall remove  such  telephonic  block
  except  pursuant  to  the  customer  of  record  providing  the  correct
  password, or a request of the customer of record made in writing  or  in
  person to such telephone corporation.
