Upon receipt of an applicant's electronic voter registration record from the auditor, and on a monthly basis, the secretary must search for potential duplicate registration records in the official statewide voter registration database by comparing the applicant's name and date of birth or other identifying information provided by the applicant on the voter registration form. Duplicates will be determined by comparing the signatures on all available records. If a voter is transferring his or her registration to a new county or if any other information on the application has been updated, the auditor of the new county must update the registration record in the state database. A duplicate registration record must not be maintained as a new registration record.
