People wishing to vote on the future of the UK in the European Union on 23 June have until midnight tonight to register.
Those who are unsure whether they are registered or are still to sign up should head to the GOV.UK website.
Joining the electoral register takes about five minutes, and those wishing to sign up will need their National Insurance (NI) number and their passport if they are living abroad.
The online form asks for your name, address, nationality, date of birth and a handful of other simple questions.
