In the crystal structure of the title compound, C5H8N3+·H2PO4, N—H...O hydrogen bonds, involving the unprotonated amino-group and the NH+ group in the pyridinium ring and dihydrogenphosphate O atoms, link the cations and anions. A long chain-like stacking of dihydrogenphosphate anions along the c-axis direction is constructed by O—H...O hydrogen bonds. Also along the c-axis direction, π–π stacking between inversion-related pyridinium rings [centroid–centroid distance = 3.8051 (10) Å] forms columnar stacks of cations.
