Devon and Cornwall Police and Falmouth Town council have released further details of the restrictions which will be in place during the G7 summit.
A number of businesses will close while others will remain open but only to serve those working at the conference.
Residents of Events Square, Discovery Quay and Campeltown Way will also be asked to produce ID before being allowed into what will become restricted areas.
People are being encouraged to use public transport where possible and to allow for extra time on their journeys in case of delays.
It comes as the National Maritime Museum in Falmouth will be used as a media centre, hosting the world’s media during the Summit.
Its closure and the closure of nearby car parks is set to cause 'unavoidable disruption around the area according to officials.
Temporary Chief Inspector Joe Mathews said: “We are working hard with our partners to minimise the impact of the Summit on the local community and we will continue to provide updates about the event in order that people can plan accordingly.
"If you have a specific question or concern please contact us at G7engagement@dc.police.uk
"We are grateful for the continued support and understanding given by residents and businesses in the area.”
Further security arrangements are still being finalised, but details will be shared as soon as possible according to the force.
A dedicated G7 Summit website has been created to provide up-to-date to help people stay informed.
