什么是SSN和美国人的SSN号码规律

SSN是 Social Security Number 的缩写,译为「社会安全号码」,为美国社会安全卡(Social Security Card)上的 9 位数字。SSN 原本目的是用于追踪个人的纳税情况,但是现在用途已被扩大到包括区分个人身份,类似中国「居民身份证号码」之作用。社会安全号码一般写作类似 450-12-3672 这样「3位 - 2位 - 4位」的形式。

用途

社会安全号码是美国联邦政府社会安全局发给公民、永久居民、临时(工作)居民的一组九位数字号码。以前的用途多用来报税用。用自己社会安全号码上报的税等纳税人退休后而领取退休金用的。但是,社会安全号码的功用已被大大地扩大了。它不仅用于报税,它还是被一般人看成能否在美国工作的一种凭据,因此,被一些人称为“工卡”(其实是错误的)。现在申请驾照,要社安卡;到银行开帐户,也要社安卡,甚至连租公寓住,也要社安卡。为什么呢?因为社安号码早已和自己的信用(Credit)联系在一起了。社安号码已在事实上成为一种类似良民证号码。因此,社安卡或号码非常重要。

Since 1973, social security numbers have been issued by our central office. The first three (3) digits of a person's social security number are determined by the ZIP Code of the mailing address shown on the application for a social security number. Prior to 1973, social security numbers were assigned by our field offices. The number merely established that his/her card was issued by one of our offices in that State.??See also High Group List of SSN's.

他们都是在服务器端验证的,不知道是什么算法...

初步研究,与所在的州是有关系的。

只要开头3个数字,ok 前3位和你州相符就可以了
