Check a Chinese USCC / business license number
Paste an 18-character Unified Social Credit Code to check the national checksum. If the company is in our index, we also list certifications and risk flags we hold. Free. No login.
One check we can run, plus records we hold
Type a company name, trade name, or 18-character USCC.
An 18-character USCC is checked against GB 32100-2015. A pass means the number is well-formed. It does not mean the company is still operating.
Certifications with a public registry link are listed separately from supplier-stated records. Empty fields are omitted.
Flags we hold are listed. If there are none, we say so.
Common questions
What does this lookup show?
We check the USCC checksum on the spot. If the company is in our index, we also list name, location, certifications (split by whether a public registry link exists), and risk flags. We do not assign a score or rate the company.
What is a USCC number?
USCC stands for Unified Social Credit Code (统一社会信用代码). It is the 18-character identifier issued to every legally registered company in China. The last character is a checksum under GB 32100-2015.
The number checks out but the company is not found?
A passed checksum only means the 18 characters follow the national encoding rules. Our index covers Chinese aluminum mills we already list. A company can have a well-formed USCC and still be outside current coverage.
From research to a supplier shortlist
Suppliers are ranked from public records and our published methodology — we don't sell leads or take pay-to-rank. Confirm prices and certifications directly with the supplier via RFQ.
