What information needs to be included on the petition about each person signing it?

Petitions to force a referendum on an ordinance adopted by the council are regulated by G.S. 160A-103, and that statute does not specify any information beyond each voter's signature. G.S. 160A-104, however, which deals with citizen-initiated amendment proposals, does specify that the petition contain each person's signature and resident address, and it would be prudent for a petition seeking to force a referendum to contain the same information. The address is necessary in order for the board of elections to be able to verify the validity of a signature.
