现在网络上办理400业务的网站比比皆是，但是正规经营的确是寥寥无几，到不正规的网站上办理了400业务，企业后续权益没有任何保障，对方一旦人去楼空，企业将会投诉无门，导致了巨大的损失。
Now the network for 400 business websites are everywhere, but the formal operation is indeed very few, to the irregular website for 400 business, enterprise follow-up rights and interests are not guaranteed, the other party once empty, the enterprise will complain, resulting in huge losses.
因为那些在网络上办理的400号码，在电信公司都是没有合法登记的，所以企业的权益就没有了任何的保障。据官方统计，关于400业务投诉最近两年成明显上升趋势，在这里我们提醒广大用户，要办理400业务，请一定到官方指定机构办理，切勿轻信网络上所谓的非法机构的虚假宣传。
Because those 400 numbers handled on the network are not legally registered in the telecommunications companies, so the rights and interests of enterprises are not guaranteed. According to official statistics, complaints about 400 businesses have been on the rise in the past two years. Here we remind users that if they want to handle 400 businesses, they must go to the official designated agencies to deal with them. Do not trust the false propaganda of so-called illegal organizations on the network.
