Cyfuniad o lythrennau a rhifau a ddefnyddir mewn sawl gwlad i ddynodi cyfeiriad post, gan amlaf trwy ei roi ar ddiwedd cyfeiriad unigol ar amlen, yw côd post (côd zip yn yr Unol Daleithiau). Mae ei fanyldeb yn amrywio. Mewn rhai gwledydd, fel Tiwnisia er enghraifft, dim ond dinas, tref neu bentref a ddynodir gan gôd post, ond mewn gwledydd eraill, fel Cymru er enghraifft, mae'r côd yn fwy manwl ac yn dynodi stryd neu ardal.
