Self-ID for voters is among issues to be examined by MPs when they question a range of election administrators and campaigners next week.
The Levelling Up, Housing and Communities committee will hear from election administrators and campaigners, including the British Youth Council, Disability Rights UK and the Joseph Rowntree Foundation.
It follows fears that council staff could be overwhelmed by a rush of people seeking papers to show they are eligible to vote in the upcoming local elections.
More than 230 councils will hold elections on 4 May, the first time photo ID will be required.
Research by the Electoral Commission four years ago found that 17% of eligible voters in Great Britain – 9.4 million people – were either missing from the electoral register or not registered at their current address.
It also revealed that one in three young people were not registered to vote.
The cross-party group of MPs will look at the case for automatic or assisted systems of voter registration and related issues concerning data protection and cyber security.
It is also likely to explore the success of outreach activities, barriers to boosting levels of voter registration, the impact of recent annual canvass reforms and the move to voter ID.
The Local Government Association (LGA) has urged people not to leave it too late to make sure they have the required ID to vote.
