    validateNationalId('BEL', '85073003328').isValid; // true

    To bundle only this country, import its definition from idnumbers/countries/bel and pass it to register():

    import { register, validateNationalId } from 'idnumbers/core';
    import { country } from 'idnumbers/countries/bel';

    register(country);
    validateNationalId('BEL', '85073003328').isValid; // true
