对于IC的申请，需要申请人、加拿大代表及制造商都务必提供company number，否则案件将无法发证。IC的网站一直在升级中，我们目前没有接到IC官方对于制造商company number的通知，但是根据reviewer们在IC E-filing的实际操作，制造商的company number是必填项目。
　　对于正在审核中的及即将开案的IC的案件，请确认申请人、加拿大代表及制造商的company number是否齐全。
       IC于2010年9月1日对网站进行了升级，并对company number做出了新的规定。
从现在开始所有company number的申请及信息修改都直接在IC网站上进行，且要求加拿大代表必须有company number。
       有IC案子正在审核人员，请检查确认您客户的加拿大代表是否已经注册申请company number。Company number的缺失或信息不完整、不正确会延误发证速度。
　　如果IC后续有正式通知，我们会立即发给大家，谢谢各位的配合。
　　具体的操作步骤请见以下IC的官方回复，请参考：
