The uniqueness problem for multiple series over orthogonal systems of functions is considered. Classes of sets of uniqueness for multiple Walsh series and for multiple series over a mixed system of functions, which extends known classes of sets of uniqueness, are obtained. A many-dimensional analogue of Privalov's theorem is established.

*Key words*:
sets of uniqueness, multiple functional series, convergence over rectangles,
Privalov's theorem.
