You must prepare and provide a corresponding number list for each polling station.1
The corresponding number list is a prescribed document that can be found in the appendix to the election rules and can be provided 'to like effect'.
There are two types of corresponding number list: one list to be to be used in polling stations, containing the ballot paper numbers and a column to add the elector numbers of voters to whom those ballot papers are issued.2
The other list is to be used at postal vote issuing sessions, containing the number and unique identifying mark of every ballot paper produced, as well as the elector numbers of postal voters. For more information on the postal vote opening process please see our guidance on Receiving and opening postal votes.
