Look up all ICP-registered websites and filing details by company name.
When you need to verify the legality of a website operated by a company in mainland China, the ICP filing information is the most direct proof. By connecting to official data interfaces, this tool returns real-time key information—such as domains, filing numbers, and review statuses—for all registered websites under a specific entity based on the full company name entered (e.g., "Alibaba (China) Co., Ltd."). An ICP filing number consists of "Provincial Abbreviation + ICP Bei + Numbers" (e.g., "Jing ICP Bei 12345678"), which is a mandatory identifier for legal website operation in mainland China.
How can I tell if a website has completed its ICP filing?
If the "Status" field in the search results shows "A: Valid", it indicates a legal filing.
Why can't I find the filing records for some subsidiaries? Different legal entities must file separately. We recommend trying to search for the holding company's name or verifying whether the subsidiary filed as an independent legal entity.
There may be a 1-3 business day delay in filing data updates. Companies must re-file after a name change, so please use the latest registered name when searching. Results are for reference only; legal validity is subject to the MIIT system.
Typical search example: Entering "Beijing Bytedance Technology Co., Ltd." will retrieve filing information for domains like douyin.com. Before entering into business partnerships, we recommend verifying that the filing entity matches the contracting entity to prevent legal risks.
