Which Uralic languages use singular, dual, and plural grammatical numbers?

Within the Uralic language family, a grammatical distinction between singular, dual, and plural numbers is found in Sami, the Ob-Ugric languages (which include Mansi and Khanty), and the Samoyedic languages.1

While these languages utilize a dual-plural distinction—effectively contrasting "two" against "more than two"—the specific linguistic elements used to mark these numbers cannot be traced back to a common source, suggesting they did not originate from a single, specialized number marker in Proto-Uralic. In some of these languages, such as Sami, the use of the dual form is restricted to personal pronouns and personal affixes. Additionally, some Uralic verbal systems, such as those found in Nenets, incorporate these three numbers into their conjugation patterns to reflect subject agreement.12
