Members of the Society are called Fellows and are known as Fellows of the Society of Antiquaries with the post-nominal initials 'FSA'. To be elected persons shall be 'excelling in the knowledge of the antiquities and history of this and other nations' and be 'desirous to promote the honour, business and emoluments of the Society'.
Proposals for membership can only come from existing Fellows of the Society. The General Secretary and staff at Burlington House are not able to assist individuals in this matter. Elections are by secret ballot, and it is possible for candidates to be rejected. The number of Fellows is limited by statute, and currently is around 3,300.
