美国人的SSN号规律

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

NOTE: The same area, when shown more than once, means that certain numbers have been transferred from

one State to another, or that an area has been divided for use among certain geographic locations.   
Any number beginning with 000 will NEVER be a valid SSN.   
The information in our records about an individual is confidential by law and cannot be disclosed except in

certain very restricted cases permitted by regulations.   

* = New areas allocated, but not yet issued
