Georgia Code Title 21. Elections § 21-2-431

(a) At every primary and election, each elector who desires to vote shall first execute a voter's certificate and hand the same to the poll officer in charge of the electors list. When an elector has been found entitled to vote, the poll officer who examined his or her voter's certificate shall sign his or her name or initials on the voter's certificate and shall, if the voter's signature is not readily legible, print such voter's name under his or her signature. As each elector is found to be qualified and votes, the poll officers shall check off the elector's name on the electors list and shall enter the number of the stub of the ballot issued to him or her, or his or her number in the order of admission to the voting machines, on the voter's certificate of such elector. As each elector votes, his or her name in the order of voting shall be recorded in the numbered list of voters provided for that purpose.

(b) If any elector was unable to sign his or her name at the time of registration or if, having been able to sign his or her name when registered, he or she subsequently shall have become, through physical disability, unable to sign his or her name when he or she applies to vote, he or she shall establish his or her identity to the satisfaction of the poll officers;  and in such case he or she shall not be required to sign a voter's certificate, but a certificate shall be prepared for him or her by a poll officer.

(c) Except as provided in Code Sections 21-2-218 and 21-2-386, no person shall vote at any primary or election at any polling place outside the precinct in which such person resides, nor shall such person vote in the precinct in which such person resides unless such person has been registered as an elector and such person's name appears on the electors list of such precinct.
