New York Election Law Section 5-213 - Inactive status.

  5-213.  Inactive  status.  1.  When  a voter is sent a confirmation
  notice pursuant to the provisions of  this  article,  the  voter's  name
  shall be placed in inactive status.
2.  The  registration poll records of all such voters shall be removed
  from the poll ledgers and maintained at the  offices  of  the  board  of
  elections  in  a  file  arranged alphabetically by election district. If
  such board uses computer generated registration lists, the names of such
  voters shall not be placed on such lists at subsequent  elections  other
  than  lists prepared pursuant to the provisions of section 5-612 of this
  article but shall be kept as a computer record at the  offices  of  such
  board.
3.  The  board of elections shall restore the registration of any such
  voter to active status if such voter notifies  the  board  of  elections
  that he resides at the address from which he is registered, or the board
  finds  that  such  voter  has validly signed a designating or nominating
  petition which states that he resides at such address, or if such  voter
  casts  a ballot in an affidavit envelope which states that he resides at
  such address, or if the board receives notice that such voter has  voted
  in  an  election  conducted with registration lists prepared pursuant to
  the  provisions  of  section  5-612  of  this  article.    If  any  such
  notification  or  information  is  received twenty days or more before a
  primary, special or general election, the voter's name must be  restored
  to active status for such election.
4. As soon as practicable, after it restores a voter's registration to
  active  status,  the  board  of elections shall send the voter, by first
  class forwardable mail, a notice advising him of the  restoration  in  a
  form  which is similar to the notice sent to new registrants pursuant to
  the provisions of section  5-210  of  this  title  and  which  has  been
  approved by the state board of elections.
5.  If the board of elections receives notice, which complies with the
  requirements of this  article,  that  a  voter  in  inactive  status  is
  residing  at  another  address within the jurisdiction of such board, it
  shall transfer the registration and enrollment of  such  voter  to  such
  other address pursuant to the provisions of section 5-208 of this title.
