Each petition signer must be a registered voter in the state of South Dakota in the jurisdiction for which the petition is circulated. Signers must sign their names as they are registered to vote or as they usually sign their names. The signer's printed name must appear below the signature. Each signature line must show a complete residence address. This can be street and house number or rural route and box number in addition to the city or town.
Zip codes are optional.
If the signer is a resident of a second or third class municipality, a post office box number may be used in lieu of a street address. Second and third class municipalities are those with less than 5000 population. Each signature line must show the month, day and year it was signed. Numbers to designate the month are permissible. Abbreviations commonly used are also acceptable.
