Homes across Northampton will be contacted by the council as it reviews and updates the electoral register.
The annual canvas will see forms sent out to households to check information on the occupants is correct, and determine who is eligible to vote in upcoming elections.
A Northampton Borough Council spokesperson said: “The annual canvassing period is an important part of the democratic process and ensures everyone with a right to vote is registered and given their chance to do so.
“Even if the details we hold are correct and haven’t changed, we still need you to confirm this to us by responding to the form we send out.”
Every household receives a paper form but where no changes are necessary you can confirm this online, by text, over the phone, or by signing and returning the form in the freepost envelope provided.
If changes are required, you will need to send your completed form back to us using the freepost envelope provided.
Failure to return this information can result in a £1,000 fine.
