 The first two digits denote the administrative province (two provinces when a province has been split after 1967); the third digit shows if the town is the chief-town of the province (odd number, usually 1 or 9, e.g.07100 Sassari) or not (even, usually 0 or 8, e.g.10015 Ivrea); the last two digits the specific town or village or the delivery post office (only in new provinces created after 1992).
