USCC vs TIN in China: What Number Do You Need to Verify a Chinese Company?
1/17/2026

When an overseas buyer asks a Chinese supplier for a tax ID, registration number, or company number, the answer is often the Unified Social Credit Code (USCC). The same identifier may appear in translated documents as a China business license number, company registration number, credit code, or tax-related identifier.
For supplier due diligence, the practical question is simple: which number helps you match the supplier to the right legal entity before contracts, invoices, or payments are approved?
What is a USCC number in China?
USCC stands for Unified Social Credit Code. It is an 18-character identifier assigned to many Chinese legal entities and is commonly shown on a Chinese business license. In day-to-day supplier checks, the USCC is usually the strongest identifier to request because it is tied to the registered entity rather than to a translated or informal trading name.
If you need a deeper explanation of the identifier itself, see the ChinVerify guide to USCC numbers in China.
What is a TIN in China, and why does the term confuse overseas buyers?
TIN means tax identification number. In many countries, buyers expect a separate tax ID that looks different from a company registration number. In China-related supplier communication, however, overseas buyers often see the USCC used where they expected a TIN, business license number, or company registration number.
That does not mean every translated document is wrong. It means the English labels can vary. A supplier may call the same underlying identifier a tax number, registration code, business license number, credit code, or company number. Your review should focus less on the English label and more on whether the identifier matches the correct Chinese legal entity.
USCC vs TIN: which identifier should you request from a Chinese supplier?
For most supplier checks, ask for the Chinese legal name and the 18-character USCC shown on the business license. The legal name helps you confirm the entity in Chinese. The USCC helps reduce confusion caused by similar English names, sales office names, or group-company branding.
If a supplier gives you only an English name or a vague tax ID, ask for a copy of the business license or the exact Chinese legal name and USCC. If the supplier refuses, delays, or provides inconsistent identifiers across documents, treat that as a due-diligence signal rather than a clerical detail.
- Best identifier to request: Chinese legal name plus USCC.
- Helpful supporting documents: business license, quotation, invoice, contract, and bank beneficiary details.
- Review goal: match the same legal entity across records and transaction documents.
Where to find the USCC on a Chinese business license
On a Chinese business license, the USCC is usually displayed near the top of the license together with the company name and registration information. The Chinese label may appear as unified social credit code. In English translations, it may be rendered as USCC, USCI, credit code, registration number, business license number, or tax number.
When reviewing a license, compare the identifier with the legal name, registered address, legal representative, business scope, and registration status returned by your company search. A matching code is useful, but it should still be reviewed in context with the whole supplier file.
How to verify a Chinese company by USCC
Start by entering the USCC or company name in the ChinVerify Checker. Review the returned entity and make sure it is the company shown on the business license, quotation, invoice, contract, and bank beneficiary documents.
- Search the USCC or Chinese legal name.
- Confirm that the legal name and identifier match the supplier documents.
- Review the registration status, registered region, and business scope for obvious mismatches.
- Compare public risk signals with the transaction value and your internal approval process.

How USCC lookup relates to China business registry search
A China business registry search helps confirm baseline facts about the legal entity: name, status, registered region, business scope, and identifiers. USCC lookup is one precise way to start that search, especially when the supplier's English name is unofficial or ambiguous.
Registry data should be treated as a starting point, not as a guarantee. The important step is matching registry facts to the commercial documents and payment controls used in the transaction.
Red flags: missing, inconsistent, or copied identifiers
Identifier problems do not automatically prove misconduct, but they are useful signals for escalation. Pause and ask for clarification when the same supplier presents different legal names, different USCCs, or documents that point to unrelated companies.
- The supplier cannot provide a Chinese legal name or USCC.
- The business license, invoice, contract, and beneficiary details show different entities.
- The USCC resolves to a company whose region, status, or business scope does not fit the supplier's claims.
- The supplier uses a group company, trading company, or unrelated entity without explaining the relationship.
Use ChinVerify to search by company name or USCC
Before approving a supplier, search the company name or USCC in the ChinVerify Checker and compare the result with the business license, invoice, contract, and beneficiary details.
The goal is not to label a company as safe or unsafe from one number. The goal is to confirm the right legal entity, identify inconsistencies early, and decide whether further review is needed before money or contractual commitments move forward.
