Title 21, Chapter 2, Section 233
(a) The Secretary of State is authorized to cause at his or her
discretion the official list of electors to be compared to the
change of address information supplied by the United States Postal
Service through its licensees periodically, but not more often than
once each year, for the purpose of identifying those electors whose
addresses have changed.
(b) If it appears from the change of address information supplied by
the licensees of the United States Postal Service that an elector
whose name appears on the official list of electors has moved to a
different address in the county in which the elector is presently
registered, the list of electors shall be changed to reflect the new
address and the elector shall be sent a notice of the change by
forwardable mail at both the old address and the new address with a
postage prepaid, preaddressed return form by which the elector may
verify or correct the address information.
(c) If it appears from the change of address information supplied by the licensees of the United States Postal Service that an elector whose name appears on the official list of electors has moved to a different address outside of the boundaries of the county or municipality in which the elector is presently registered, such elector shall be sent a confirmation notice as provided in Code Section 21-2-234 at both the old and new addresses. If the elector confirms the change of address to an address outside of the boundaries of the county or municipality in which the elector is presently registered, the elector's name shall be removed from the appropriate list of electors. If the elector responds to the notice and affirms that the elector has not moved, the elector shall remain on the list of electors at the elector's current address. If the elector fails to respond to the notice within 30 days after the date of the notice, the elector shall be transferred to the inactive list provided for in Code Section 21-2-235.
(d) Whenever an elector's name is removed from the list of electors
by the county registrars because the elector has furnished in
writing to the registrar a residence address that is located outside
of the elector's present county of registration, the registrars
shall notify the elector in writing at the elector's new address
that the elector's name is being deleted from the list of electors
for that county and that the elector must reregister in the new
county of residence in order to be eligible to vote. The registrars
shall provide the person with the appropriate form for registration
at the time of such notice.
(e) Nothing in this Code section shall prevent the removal from the
list of electors of an elector for ineligibility to vote.
