Each City has its own alphanumeric code, where is it located?
每个城市都有自己的字母数字代码，它在哪里？
The City of birth is one of the information reported in the tax code which, as a reminder, is used by the tax registry to register and check data relevant to the tax authorities.
The alphanumeric code that identifies the city of birth is found exactly after our day of birth and is made up of a letter and three digits (eg: those born in Milan will find the code F205). This code cannot be deduced through particular calculations since each City holds one deposited with the Revenue Agency.
出生城市是税务代码中报告的信息之一，作为提醒，税务登记处使用该信息来注册和检查与税务机关相关的数据。
识别出生城市的字母数字代码正好在我们的出生日期之后，由一个字母和三个数字组成（例如：在米兰出生的人会找到代码 F205）。这个代码不能通过特定的计算来推断，因为每个城市都有一个存放在税务局的地方。
