The problem

Dun & Bradstreet's public directory redacts the street address of mainland Chinese companies, and signing in doesn't unlock it. Compliance, sourcing, and vendor checks all need the full registered address, the Unified Social Credit Code, registered capital, and employee count — and getting them means emailing a broker or paying per lookup.

What you get

Enter a 9-digit DUNS number and get the official Chinese registry record:

Complete registered street address, in Chinese and English
Unified Social Credit Code (统一社会信用代码)
Registered capital and currency, registration date, registration status
Legal representative, key personnel, and related companies
SIC / NAICS codes, employee count, industry classification
Capacity profile and ESG ratings where available

Why it's different

Every field comes from D&B's own China self-service registry endpoint — the same source the paid API reads. This is just a free front door to it, with the response rendered in six languages.
