Tennessee Code Title 2. Elections § 2-7-141

(b)(1) A registered voter whose registration has been transferred pursuant to § 2-2-129(b)(2)(A), but who has in fact not moved or has moved to a different address from that supplied by the postal service, shall be required to make a written affirmation of such registered voter's current address of residence and that the voter is entitled to vote before voting. This affirmation shall be made on a standard form provided by the county election commission and shall be made before the officer of elections at the voter's polling place or the appropriate election official at an early voting site. The voter may then vote using the same method as any other voter at the polling place. The fact that this voter is a registered voter and has not already voted in the current election must be confirmed by the county election commission before this person may vote.

(2) A county election commission may establish a centrally located site or sites to be designated by such commission for voters voting under this subsection (b).

(3) If a county election commission elects to establish a centrally located site or sites, then the official at such polling location shall notify the voter that the voter has the option to vote either at the new polling place or at a centrally located site or sites. If a central location is other than the county election commission office, then such centrally located site shall be equipped with computer capabilities linked to the county election commission office to allow the voter's records to be changed or corrected in the same manner as if the voter were to appear at the county election commission office on election day in order that the voter may cast the appropriate ballot.
