中国邮寄爱尔兰的邮编
在实际操作中，从中国大陆邮寄到国外（包括爱尔兰）的国际邮件，只需要在信封上用中文写上是邮寄到爱尔兰的（还要附上详细城市、地址），可以不用填写爱尔兰邮政编码999014，也一样可以递送到爱尔兰，在本站向邮局的11185电话咨询中也证实向国外邮寄信件、物品不需要填写999014。
为了便于在爱尔兰内部的递送，需要用爱尔兰当地使用的语言来写清详细地址，最好填写上当地的爱尔兰邮编以便让爱尔兰的邮局分发、邮递员递送。

爱尔兰内部的邮政编码
爱尔兰是世界上少数几个不使用邮政编码的国家/地区。
柏林是分了邮区号码的，但其它地区暂无。
近年来，爱尔兰传闻将引入全国的邮政编码系统，但目前尚未实施。
