New York Laws
Title 7 - Checks Against Fraudulent Practices
5-712 - Confirmation Notices.

(b) If a notice sent pursuant to paragraph (a) of this subdivision to
the voter at the new address is returned as undeliverable, the board of
elections shall send another such notice to the address at which the
voter was originally registered.
3. Such notices shall be in a form prescribed by the state board of
elections and shall include a postage-paid return card on which the
voter may confirm the fact that he still resides at the address to which
the notice was sent, or notify the board of any change of address. Such
notices shall request all voters who receive the notice to reply with
their current addresses. Such notices shall request all voters who
receive the notice to reply with their current addresses and shall state
that voters who have not moved or who have moved within the county or
city and who do not respond may be required to vote by affidavit ballot
and that if they do not vote in any election up to and including the
second federal election after such notice, their registrations may be
cancelled. Such notices sent to addresses in New York state shall also
include a mail registration form and information on how voters who have
moved to a different city or county may reregister.
4. No such confirmation notices shall be sent between June first in
any year and the date of the general election in such year or in the
ninety days before a spring primary election except that such notices
shall be sent forthwith to persons for whom an acknowledgment of
acceptance of registration sent pursuant to subdivision nine of section
5-210 of this article is returned to the board of elections as
undeliverable and to every registered voter for whom the board of
elections receives a notice of change of address described in paragraph
a of subdivision two of this section to an address not in such city or
county.
5. All voters or applicants to whom a confirmation notice is sent,
pursuant to the provisions of this section, shall forthwith be placed in
inactive status.
