In the title compound, 2C8H12NO+·H2P2O72-, the linked PO4 groups of the diphosphate anion are almost eclipsed and the P-O-P angle is 134.45 (7)°. In the crystal, infinite ribbons of H2P2O72- anions propagate in , being linked by strong O-HO hydrogen bonds. The 4-methoxybenzylammonium cations bond to the diphosphate chains by N-HO and C-HO links, and are themselves linked by C-H interactions.
