If residents wish to vote at these elections they must be registered by 11.59pm on Tuesday 17 April.
Residents already on the electoral register do not need to take any action and will automatically receive a poll card by 10 April.
Residents aged 18 or over on polling day can vote in these elections if they are a British, Irish, qualifying Commonwealth, or European Union citizen and have registered to vote in Cambridge.
People can register to vote online at www.gov.uk/register-to-vote if they have their National Insurance number to hand – a process which will only take a few minutes.
Anyone without access to the internet can request a paper form by calling the council on 01223 457048.
Antoinette Jackson, Chief Executive of Cambridge City Council and Returning Officer for the local elections, said: “I would encourage you to register by 17 April, so you have the opportunity to vote on 3 May, as the local councillors you elect make some important decisions on behalf of Cambridge residents.
“If you have moved house recently, are a student who wants to vote in Cambridge, or if you know you are not yet registered, it is very straightforward to do so at www.gov.uk/register-to-vote.
“Since registering to vote is a separate process from other council services, you should not assume that because you pay council tax or have informed us of your address in the city, that you are registered to vote.”
People who have already registered to vote but are planning to be away from Cambridge on 3 May can apply to vote by post up until 5pm on Wednesday 18 April.
People can appoint someone else to vote on their behalf by applying to vote by proxy up until 5pm on Wednesday 25 April.
