Eine Postleitzahl ist ein geografischer Code, der zur Identifizierung eines Ortes oder eines Gebiets verwendet wird. Er hilft bei der Identifizierung eines bestimmten Ortes, indem er eine Reihe von geografischen Koordinaten wie Straßenadresse, Stadt, County, Staat und Land in einem fünfstelligen Code kombiniert. Die Postleitzahl 90210 für die Stadt Beverly Hills, Kalifornien, setzt sich beispielsweise aus den Zahlen 9, 0, 2, 1 und 0 zusammen.
