# 如何使用邮政编码对地址号进行地理编码
<a name="how-to-geocode-address-postal-code"></a>

在邮政编码非常具体（每个邮政编码仅对应同一街道上的少数几个地址）的国家/地区，只需知道门牌号和邮政编码就能找到相应的地址。这种做法在交通运输和包裹配送物流领域十分常见。加拿大、英国、荷兰、美国（ZIP\+4）、以色列、爱尔兰和新加坡支持此功能。在爱尔兰和新加坡，邮政编码都能提供确切的位置详细信息，甚至能精确到具体的门牌号。

### 使用邮政编码在新加坡和爱尔兰对地址进行地理编码
<a name="geocode-postal-code-example2"></a>

在爱尔兰，Eircode 系统会为每栋住宅和每家商铺分配一个唯一代码；而在新加坡，邮政编码同样非常具体。在这两个国家，仅凭邮政编码就能确定一个确切的地址，而无需街道名称、城市或门牌号。
+ 新加坡：6 位数邮政编码
+ 爱尔兰：7 字符 Eircode
