Surrey County Council has commissioned a large-scale broadband coverage survey as part of plans to narrow the growing digital divide.
The county's 84 town and parish councils are being invited to participate in the study, which is being conducted by the Surrey Strategic Partnership.
It is hoped that all households and businesses, in both urban and rural areas, will be equipped with high-speed connections by 2013.
Dr Andrew Povey, leader of the council, said the survey would help to identify areas of the county which currently suffer from poor broadband access.
"There are still people in Surrey who cannot receive a broadband service, or if they can, it is patchy," he told the BBC.
"The internet is central to our daily lives. Everyone should have access to decent broadband."
Dr Povey added that faster broadband access is "vital" to keep Surrey's economy moving.
Earlier this week, broadband campaigners in Surrey Hills called on internet service provider BT to reveal whether the area is destined to be included in its ongoing fibre broadband rollout.
