In the crystal structure of the title compound, C4H6N3+·HSO4−, hydrogen sulfate anions self-assemble through O—H⋯O hydrogen bonds, forming chains along the b axis, while the cations form centrosymmetric pairs via N—H⋯N hydrogen bonds. The 2-amino­pyrimidinium pairs are linked to the sulfate anions via N—H⋯O hydrogen bonds, forming a two-dimensional network parallel to (10). In addition, weak inter­molecular C—H⋯O contacts generate a three-dimensional network.
