Miss. Code § 23-15-151
The circuit clerk of each county is authorized and directed to prepare and keep in his or her office a full and complete list, in alphabetical order, of persons convicted of voter fraud or of any crime listed in Section 241, Mississippi Constitution of 1890. A certified copy of any enrollment by one clerk to another will be sufficient authority for the enrollment of the name, or names, in another county. A list of persons convicted of voter fraud, any crime listed in Section 241, Mississippi Constitution of 1890, or any crime interpreted as disenfranchising in later Attorney General opinions, shall also be entered into the Statewide Elections Management System on a quarterly basis. Voters who have been convicted in a Mississippi state court of any disenfranchising crime are not qualified electors as defined by Section 23-15-11 and shall be purged or otherwise removed by the county registrar or county election commissioners from the Statewide Elections Management System.
