In the title compound, C(5)H(7)N(2) (+)·N(3) (-)·C(5)H(6)N(2), all N atoms of the azide anion are situated on a twofold rotational axis, so the 4-amino-pyridinium cation and 4-amino-pyridine mol-ecule, being related by symmetry, occupy one position in the asymmetric unit. Inter-molecular N-H⋯N hydrogen bonds generate a three-dimensional hydrogen-bonding network which consolidates the crystal packing.
