People are being encouraged to reply to South Kesteven District Council's annual voter registration canvass to ensure they are registered and eligible to vote in next year's elections.
Initial letters were distributed in July but reminders are being sent to residents of the importance of checking this information, if they have yet to do so.
Beverly Agass, Electoral Registration Officer, said the aim of the form is to ensure that the electoral register is up to date and to identify any residents who are not registered.
She said: "With elections taking place in our area in May 2017, this is an opportunity for residents to make sure they are registered and able to take part.
"Anyone that wants to vote must be registered. To make sure you are able to have your say at the elections next year, simply check the form when it arrives and reply as promptly as possible.
"All households must respond even if there are no changes to be made to the information. You can do this by returning the form in the pre-paid envelope provided, online, by telephone or by text.
"If you're not currently registered, we'll send you information explaining how to do this or you can just go online to apply to register at www.gov.uk/register-to-vote "
It's particularly important that anyone who has moved address recently looks out for the form and checks whether they are registered.
Mrs Agass added: "The annual canvass is an opportunity for people to easily check whether they're registered. It's essential for a healthy democracy that everyone who is entitled to vote is able to do so, and, for those who need to register, it is now easier than ever with the online system of registration."
