Its geographical interests therefore cover, in addition to the modern administrative county of Surrey, the areas now forming the London boroughs of Lambeth, Wandsworth, Southwark, Croydon, Kingston, Merton, Sutton, and Richmond; as well as the district of Spelthorne, which became part of the county only in 1965.
The Society's headquarters, which include an extensive library, are located at Castle Arch, Guildford.
The building also houses Guildford Museum, itself originally established by the Society, although now quite independent.
The Society's official journal is Surrey Archaeological Collections, first published in 1858, and which now appears annually.
The Society also issues a regular bimonthly Bulletin, containing news, short reports and articles, and notices of forthcoming events.
