The most authoritative query method for the qualification of construction enterprises in China is the following website, which is generally called "four databases and one platform". It will show what qualifications the enterprise has, which projects it has participated in, and some will enter detailed information, and the scale of participating projects will be written clearly. In addition, it is clear at a glance which personnel the enterprise has registered.
According to this picture, you can easily find the enterprise you need and make an inquiry. If it is still unclear, you can consult Chen Gong (click on the background of the home page) to help you inquire. There is also an authoritative website, namely official website, the provincial housing and construction departments. For example, Guangdong's construction industry data open platform is also relatively authoritative, and official website and provincial housing and construction departments can also inquire. Take Guangdong Province as an example, the link is below, and friends who need it can check it themselves.
According to the specific situation of the enterprise, select the corresponding options and make inquiries. If it is still unclear, you can consult Chen Gong (click on my avatar to see the background of the home page), or you may help with the inquiry. If it is a company that wants to transfer its qualifications, Chen Gong would like to remind you:
After the seller inquires about your website, it's best to search in official website to avoid some lawless people making their own links to deceive people. You can search for four databases and one platform by yourself, or you can visit official website of the Ministry of Housing and Urban-Rural Development and official website of the Ministry of Housing and Urban-Rural Development. If you have any questions, you can communicate with Chen Gong (homepage backstage).
Chen Gong attached a detailed explanation of the ultra-detailed qualification process of the whole network, which many friends have collected. Friends in need can take it themselves or pay attention to Chen Gong, and bring you first-hand information about the construction industry.
