（1）前1、2位数字表示：所在省份的代码；
身份证号与省份的关系 11 北京市；12 天津市；13 河北省；14 山西省；15 内蒙古自治区；21 辽宁省；22 吉林省；23 黑龙江省；31 上海市；32 江苏省；33 浙江省；
34 安徽省；35 福建省；36 江西省；37 山东省；41 河南省；42 湖北省；43 湖南省；44 广东省；45 广西壮族自治区；46 海南省；50 重庆市；51 四川省；52 贵州省；

（2）第3、4位数字表示：所在城市的代码；
（3）第5、6位数字表示：所在区县的代码；
（4）第7~14位数字表示：出生年、月、日；
（5）第15、16位数字表示：所在地的派出所的代码；
（6）第17位数字表示性别：奇数表示男性，偶数表示女性；
第十八位数字的计算方法为：
1.将前面的身份证号码17位数分别乘以不同的系数。
从第一位到第十七位的系数分别为：7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 2
2.将这17位数字和系数相乘的结果相加。
3.用加出来和除以11，看余数是多少？
4.余数只可能有0 1 2 3 4 5 6 7 8 9 10这11个数字。
其分别对应的最后一位身份证的号码为1 0 X 9 8 7 6 5 4 3 2。
