§ § 1506Checkup of registers

(a) General rule.--At any time prior to the 30th day
preceding an election, a commission may mail to any qualified
elector whose name appears in any district register a notice
setting forth the elector's name and address as it appears in
the register and requesting the elector in case of any error
to present the notice within ten days at the office of the
commission to have the error corrected and warning that any
discrepancy between the qualified elector's actual name and
address and his name and address as recorded in the original
register will constitute ground for challenging the elector's
vote. The notice shall contain on the outside "Do not forward,
return to board of elections" and a request of the postal
service to return it within five days if it cannot be delivered
to the addressee at the address given.
   (b) Checkup by postal service.--At any time prior to the
30th day preceding an election, the commission may cause a
checkup to be made by the postal service of any qualified
elector whose name appears in any district register.
   (c) Quadrennial checkups.--At least once in each four years
the commission may conduct a checkup of each registered elector
by either of the methods provided for in subsections (a) and
(b).
   (d) Failure to deliver notice.--Upon the return by the
postal service of any notice which it has been unable to deliver
at the given address because the addressee cannot be found there
or upon report by the postal service that any registered elector
does not reside at the address given on the registration card,
the commission shall do one of the following:
       (1) Direct an authorized employee to visit in person
   the address of the qualified elector and, if the employee
   finds that the qualified elector does not reside at the
   address, to leave at the address the notice prescribed by
   subsection (e).
       (2) Mail to the registered elector at the address given
   on the registration card the notice prescribed by subsection
   (e). The notice shall be sent as first class mail and shall
   contain on the outside a request to the postmaster to forward
   it if the addressee does not reside at the address given
   thereon.
   (e) Communication with commission.--The notice stipulated
by subsection (d) shall require the registered elector to
communicate with the commission by a date designated by the
commission, which shall be not less than ten days nor more than
30 days from the service or mailing of the notice and in any
case not later than the 15th day preceding an election, and
satisfy the commission of qualifications as a qualified elector.
At the expiration of the time specified in the notice, the
commission shall cancel the registration of a person who has
not communicated with the commission and proved qualifications
as a qualified elector, except that, if a registered elector
who has been mailed the notice prescribed by this subsection
communicates with the commission claiming the right to remain
registered at the address to which the original notice was
mailed, the commission shall investigate and, if not satisfied
of the right of the registered elector to remain registered at

the address, shall cancel the registration of the elector. Every
elector whose registration is canceled under this section must
register in the manner provided by this part in order to be
eligible to vote at any election.
   (f) Elector in military service.--The registration of a
person in military service shall not be canceled by reason of
the failure of the person to reside at the address appearing
upon the district register if the person resided at the address
on the date of entering military service.
