The USCC (Unified Social Credit Code), in Chinese统一社会信用代码, is the functional equivalent of a tax ID for a Chinese company: a unique 18 character code that identifies it before the business registry, the tax administration and customs. Names get translated, abbreviated and confused. The USCC does not.
Where it comes from
Until 2015, a Chinese company accumulated several separate numbers: its business licence number, an organisation code and a tax registration number. The reform known as three certificates in one (三证合一) unified them into a single code, the USCC, rolled out from October 2015 and today the standard identifier of any entity registered in mainland China.
Anatomy of the 18 characters
The code combines digits and uppercase letters, and each segment has a meaning:
| Position | Content | What it indicates |
|---|---|---|
| 1 | 1 character | Registering authority. 9 corresponds to the business registry, the most common for suppliers. |
| 2 | 1 character | Entity type within that authority. |
| 3 to 8 | 6 digits | Code of the administrative division where it is registered: province, city and district. |
| 9 to 17 | 9 characters | The entity's own organisation code. |
| 18 | 1 character | Check digit, calculated from the previous 17. |
A practical detail: to avoid confusion, the system does not use the letters I, O, Z, S or V. A code containing any of them has been transcribed wrongly or simply invented.
Where to find it
- On the supplier's business licence, 营业执照, where it appears prominently next to the legal name.
- On official invoices and contracts. Its absence on an invoice is a signal in itself.
- On the company's public record on GSXT, the official registry.
What you can do with it
- Identify without ambiguity. Searching by USCC on GSXT takes you to a single company, without the problems of translated names. The step by step is in the verification guide.
- Cross check documents. The USCC on the licence, the contract, the invoice and the destination bank account must belong to the same entity. This is where most impersonation frauds fall apart, which is why we set it out in the guide on the checks before the transfer.
- Locate the supplier geographically. Digits 3 to 8 reveal where the company is registered. If they tell you the factory is in Guangdong and the code points to another province, an explanation is owed.
The three inconsistencies we see most
- The USCC belongs to another company. The supplier sends a real code, but for an entity different from the one signing the contract or collecting the advance. Sometimes carelessness; sometimes not.
- An undisclosed intermediary. The USCC on the invoice corresponds to a trading company and not to the factory that appears in the photos and the sales pitch. Not illegal, but it changes your chain of liability and you should know before paying.
- A malformed code. A length other than 18, forbidden letters or a check digit that does not add up. Almost always sloppy transcription, but it forces you to ask for the original licence.
In our reports the USCC is the starting point. We verify that the code, the legal name, the representative and the collection account belong to the same entity, and from there we build the rest of the analysis: registration status, capital, litigation and corporate links.
Quick questions
Do all Chinese companies have a USCC?
All entities registered in mainland China have had one since the system was rolled out. If an active supplier cannot give you its USCC, it cannot give you its legal identity, and that answers the underlying question.
Does the USCC work for Hong Kong or Taiwan companies?
No. Hong Kong and Taiwan have their own registries and identifiers. The USCC identifies mainland Chinese entities.
Is the USCC the Chinese company's VAT number?
It is the closest thing there is: after the 2015 unification the same code identifies the company for both registration and tax purposes. But it is not an EU VAT number and it cannot be validated in VIES. We cover this in the guide onthe tax ID of a Chinese company.
Is verifying the USCC enough to pay with peace of mind?
It is the first filter, not the last. It confirms the entity's identity, but it does not tell you whether it carries litigation, whether its capital is real or who is behind it. For meaningful amounts, those layers deserve a report.
