Forms were sent to all households in Milton Keynes over the last few weeks to check that information currently held on the Register of Electors is correct.
If residents have not responded to this form already, time is running out before the register is published in February.
There will be elections on Thursday, May 22 across the whole of Milton Keynes to vote for new borough councillors and in the European Parliamentary elections.
Residents are reminded that if they are not on the Register of Electors they will not be able to vote and it is a legal requirement to fill out the register form.
If there are no changes to the details printed on the form, then residents can respond by telephone, internet or by text to confirm that the information is right.
If the Register of Electors details are correct then residents can call the free phone number 0800 197 9866,
