Finding a Chinese company registration number is a common and essential task for foreign investors, compliance teams, and business partners. In China, this number is formally known as the Unified Social Credit Code (USCC), and it is required for company verification, tax filings, banking, contracts, and due diligence.
This guide explains how to find a Chinese company registration number in 2025 using official government systems, what information you need in advance, and how foreign firms can avoid common mistakes during the search process.
What Is a Chinese Company Registration Number?
The Chinese company registration number, officially called the Unified Social Credit Code, is an 18-character alphanumeric identifier issued to every registered legal entity in China. It functions as a nationwide business ID and is used across multiple government systems.
In China, company registration information is maintained by the State Administration for Market Regulation (SAMR) , which oversees business registration and the national enterprise credit information system. Official searches should always be conducted through government-operated databases to ensure accuracy.
The registration number appears on the company’s business license and is required for:
- Tax registration and online tax filing
- Bank account opening and updates
- Customs and import-export declarations
- Contract verification and compliance checks
- Corporate due diligence and background reviews
Why Foreign Firms Often Need to Look It Up
Foreign companies frequently need to find a Chinese company registration number when working with suppliers, customers, joint-venture partners, or newly established subsidiaries. In many cases, the number is required before any formal transaction can proceed.
Typical scenarios include:
- Verifying the legal status of a Chinese counterparty
- Preparing compliance or audit documentation
- Registering contracts or making official filings
- Supporting tax, payroll, or customs processes
What You Need Before Searching
Before attempting to search for a Chinese company registration number, prepare the following information:
- The company’s official Chinese name (English names will not work)
- Optional: registered city or province
- Optional: legal representative’s name
Using the correct Chinese company name significantly improves search accuracy and avoids confusion with similarly named entities.
How to Find a Chinese Company Registration Number Step by Step
Step 1: Use the National Enterprise Credit Information System
The most authoritative source is China’s national enterprise credit information disclosure system operated by the market regulation authorities. This system provides official registration details for companies across China.
You can search by entering the full Chinese company name. The Unified Social Credit Code will be displayed together with registration status, address, and business scope.
Step 2: Review the Search Results Carefully
Many companies in China have similar or nearly identical names. Always confirm:
- Registered address
- Legal representative
- Company type (WFOE, domestic company, joint venture)
The correct Chinese company registration number will be listed next to the verified entity.
Step 3: Cross-Check with Business License Records
If available, compare the registration number with scanned business licenses or official filings. This step helps confirm that the number is current and valid.
Can Foreign Users Access These Systems?
Yes. Most official Chinese business registration systems are accessible from outside China. However, foreign users may encounter practical challenges such as:
- Chinese-only interfaces
- CAPTCHA verification
- Browser compatibility issues
Using a modern browser and preparing Chinese text in advance usually resolves these issues.
Common Mistakes to Avoid
- Searching with English company names
- Ignoring similar company names in different cities
- Using outdated screenshots or unofficial databases
- Assuming the registration number never changes after restructuring
Always rely on official sources when accuracy matters for compliance or transactions.
How the Registration Number Is Used in Ongoing Compliance
Once identified, the Chinese company registration number is used across multiple compliance processes. For example, it is required when filing taxes through China’s online tax systems and when completing annual compliance reporting.
For foreign investors establishing or managing entities in China, understanding how the registration number fits into the broader compliance framework is critical. For a full overview of entity setup and regulatory obligations, see our China WFOE setup guide .
