Cuirtear an cód iarmhír tar éis an bhunchód. Nuair is ann do shraith iolrach cód poist, ba cheart iad a shocrú ó chlé go deas in ord na gcód poist atá liostaithe sa tábla cóid iompair. Scartar roinnt ainmneacha cód poist ón mbunchód le ponc beag.
Cód poist - Struchtúr Inmheánach
A , B , C , D , E - athruithe struchtúracha inmheánacha
Sampla: Imthacaí liathróid teagmhála uilleach 7205C, 7205E, 7205B, uillinn teagmhála C-15 céim, uillinn teagmhála E-25 céim, uillinn teagmhála B-40 céim.
Sampla: sorcóir sorcóireach, sorcóir sféarúil agus imthacaí sorcóir sféarúil sá N309E, 21309E,29412E- dearadh treisithe, feabhsaítear an cumas ualaigh imthacaí.
VH - imthacaí sorcóir sorcóireach comhlántach iomlán le rollóirí féinghlasála (tá trastomhas na rollóirí difriúil ó thrastomhas na n-imthacaí caighdeánacha den chineál céanna).
