根据国人身份证校验规则调整外国人身份证校验
根据国家移民管理局公布的新版外国人永久居留身份证适配性改造要点。核心点如果下图:
你会发现18位身份证,我们的身份证和外国人永居证的差别只是前6位的校验不同。
- 身份证校验规则:
//身份证
function checkSFZ(_sfz) {
var vcity = {
11: "北京",
12: "天津",
13: "河北",
14: "山西",
15: "内蒙古",
21: "辽宁",
22: "吉林",
23: "黑龙江",
31: "上海",
32: "江苏",
33: "浙江",
34: "安徽",
35: "福建",
36: "江西",
37: "山东",
41: "河南",
42: "湖北",
43: "湖南",
44: "广东",
45: "广西",
46: "海南",
50: "重庆",
51: "四川",
52: "贵州",
53: "云南",
54: "西藏",
61: "陕西",
62: "甘肃",
63: "青海",
64: "宁夏",
65: "新疆",
71: "台湾",
81: "香港",
82: "澳门",
91: "国外"
};
// 检查号码是否符合规范,包括长度,类型
var isCardNo = function (card) {
// 身份证号码为15位或者18位,15位时全为数字,18位前17位为数字,最后一位是校验位,可能为数字或字符X
var reg = /(^\d{15}$)|(^\d{17}(\d|X)$)/;
if (reg.test(card) === false) {
return false;
}
return true;
};
// 取身份证前两位,校验省份
var checkProvince = function (card) {

return false;
}
return true;
};
// 检查生日是否正确

}
return false;
};
// 校验日期
var verifyBirthday = function (year, month, day, birthday) {
var now = new Date();
var now_year = now.getFullYear();
// 年月日是否合理

&& (birthday.getMonth() + 1) == month
&& birthday.getDate() == day) {
// 判断年份的范围(3岁到100岁之间)
var time = now_year - year;

return true;
}

- 外国人永居证校验规则:
//外国人身份证(新版永居证证件号码18位)
function checkOutSFZ(_sfz) {
//参考移民管理局的文档:https://www.nia.gov.cn/20231013/2.pdf
//格式:9(身份标识码) 32(受理地代码) 682(国家和地区代码) 19850101(出生日期) 001(顺序码) 7(校验码)。

}
注:如果你想校验得更详细,可以把国家代码校验(证号的前4-6位,参考全球所有的国家代码/国家区号,添加枚举校验),性别校验(证号的倒数第2位,1-男,2-女)加上。甚至2017 版外国人永久居留身份证也能做一些基础校验。这个自行添加。
