What is the Business Registration Number?

Learn how to understand and verify the official registration numbers of suppliers from Mainland China and Hong Kong.

When you browse a supplier’s profile on Indexfox, you will often see a Business Registration No. displayed in their Business Identity section. This number represents the official legal identity of the company.

1. Mainland China: Unified Social Credit Code

For companies registered in Mainland China, this is an 18-digit alphanumeric code known as the Unified Social Credit Code (统一社会信用代码).

  • It is unique to each legal entity.
  • It serves as the company’s business license number, tax registration number, and organization code.
  • How to Verify: You can verify the existence and legal status of any Mainland Chinese company by entering this 18-digit code or their Chinese company name into the official National Enterprise Credit Information Publicity System (GSXT).

2. Hong Kong: Business Registration Number (BRN)

Many Chinese manufacturers establish a corporate entity in Hong Kong to handle international contracts, banking, and logistics. For these entities, you will see a Hong Kong registration number.

Why is this important?

Information asymmetry is a major risk in global trade. A verified registration number proves that the company is a legally registered entity capable of entering into binding contracts and issuing official commercial invoices.

Note: While Indexfox manually verifies the registration status of our Premium Suppliers during onboarding, we always recommend buyers perform their own due diligence (DD) before transferring funds.
