A new voter registration system called Individual Electoral Registration (IER) comes into force this summer in the biggest change to voter registration in 100 years.
Instead of the head of the household being responsible for registering everyone who lives at an address, every individual will be responsible for their own voter registration.
Mansfield District Council plans to write to everyone in the district next month to tell them about the change.
Council managing director Ruth Marlow said: “We would encourage residents to wait until they receive that letter as it will tell them what, if any, action they need to take to ensure they are on the new register.”
The new register will be published on 1 December.
