Electoral roll

An electoral roll (variously called an electoral register, voters roll, voters list, poll book or other description) is a compilation that lists citizens who are entitled to vote for particular elections in a particular jurisdiction. The list is usually broken down by electoral districts, and is primarily prepared to assist election officials at polling places. Most jurisdictions maintain permanent electoral rolls, which are updated continuously or periodically (such as France which updates them annually), while some jurisdictions compile new electoral rolls before each election. Electoral rolls are the result of a process of voter registration. In most jurisdictions, voter registration (and being listed on an electoral roll) is a prerequisite for voting at an election. Some jurisdictions do not require voter registration, and do not use electoral rolls, such as the state of North Dakota in the United States. In those jurisdictions a voter must provide identification and proof of entitlement to vote before being permitted to vote.

Electoral rolls and voter registration serve a number of functions, especially to streamline voting on election day. Voter registration can be used to detect electoral fraud by enabling authorities to verify an applicant's identity and entitlement to a vote, and to ensure a person doesn't vote multiple times. In jurisdictions where voting is compulsory, the electoral roll is used to indicate who has failed to vote.
