validateNationalId('KOR', '800101-1234567').isValid; // true
To bundle only this country, import its definition from idnumbers/countries/kor and pass it to register():
import { register, validateNationalId } from 'idnumbers/core';
import { country } from 'idnumbers/countries/kor';
register(country);
validateNationalId('KOR', '800101-1234567').isValid; // true
