A physical exhibitor is defined as an entity (company, individual person or organisation) which has been granted approval for an exhibitor stand space by the exhibition organiser and which presents or distributes products, services and/or rights with personnel. There must be the opportunity for synchronous interaction with the exhibition visitors during the official running time (e.g. personal conversation).

An exhibitor may be represented as a main exhibitor, co-exhibitor or joint stand exhibitor.

A physical exhibitor may be counted more than once, provided that he is represented in more than one exhibitor stand space, which must be in a visually distinctly separate area, and provided that the exhibitor targets different audiences with different key products.
