Ala. Code § 45-58-111.24: Methods of Voter Reidentification.

A voter may reidentify himself or herself in any one of the following ways:

(1) He or she may reidentify himself or herself by appearing in person at the office of the board of registrars and answering such questions and submitting such proof as may reasonably be required by the board of registrars or one of its duly authorized employees to establish his or her identity and place of legal residence and that he or she has not become disqualified from voting in the county.

(2) He or she may reidentify himself or herself by filling in and mailing to the office of the board of registrars the completed answers to the questions as may reasonably be propounded and mailed to him or her in a written questionnaire by the board of registrars, or on a form which the board of registrars shall cause to be printed in all newspapers of general circulation published in the county. The questionnaire may contain such questions as are reasonably necessary to establish the identity of the person signing the questionnaire, the place of his or her legal residence, and that he or she has not become disqualified from voting in the county. All answers to the questionnaires shall be signed by the elector in the presence of at least two witnesses who shall sign their answers as attesting witnesses.

(3) He or she may reidentify himself or herself at the general election of 1980, or at any election at which he or she votes during 1980 and any tenth year thereafter, by filling out and signing answers to the questionnaire prepared by the board of registrars in the presence of a clerk, manager, or returning officer who shall sign the answers of the voter as an attesting witness. The returning officer shall transmit all such filled in and signed answers to questionnaires to the board of registrars.

(4) Any voter who has been purged from the list of qualified electors for failure to reidentify may reidentify himself or herself on any election day at the office of the board of registrars or judge of probate by appearing in person. He or she will be given a certificate to take to the polls in order to vote on that day.
