What can i do with company registered number?

In my article, about "How to Verify Chinese" i told about getting a chinese registration number and double checking to see if the company is legit. Let's say I get a number how can I double check to make sure the company is legitimate.

After you obtain their company registered number, you may call local government authorities to check it out. In China, there are several kinds of company types, so the numbers should be different because some companies do not have the right to export or import directly by themselves. In China every legitimate company has a unique registered company number from local administrative authorities, the responsible organ at all levels is called Industry and Commerce Bureau, for example, if your target company is located in Changsha, you may contact Changsha Industry and Commerce ( http://www.csaic.gov.cn Tel: 86-731-2891606 8861324 ), Tell them the registration company number and request them to check it out for you in China. Here comes two questions, on the one hand, few local officials knows English in China, you have to speak Chinese when verify it by yourself. On the other hand, they never overwork and work at weekends for you in China, it's hard to meet their business time. This is my answer, hoping it will help you a lot.

Good luck to everybody!
