Unified Social Credit Code (USCC)
The 18-character identity code used for Chinese legal entities and other organizations, explained by source, structure, scope, and common misreadings.
A Unified Social Credit Code (USCC) is the 18-character identity code assigned to a registered legal entity or other organization in China. It identifies the subject. Despite the words “social credit,” the code is not a credit rating, risk score, or statement that the organization is trustworthy.
Where the USCC appears
For an overseas buyer, the clearest source is usually the supplier's Chinese business licence, under the field 统一社会信用代码. China's market-entity registration rules list the USCC among the information carried on a business licence. See the official licence rule.
The same value may appear as a taxpayer identification number on an invoice or tax document. The State Taxation Administration's English note says that an entity TIN generally uses the 18-character USCC under the current system. Read the official TIN note. That does not make “USCC” and “TIN” identical concepts in every historical or special case; USCC vs China Tax Number covers the distinction.
The 18 positions
The National Development and Reform Commission describes five parts. Read the code from left to right:
- Position 1: registration-management department code.
- Position 2: organization category code.
- Positions 3-8: administrative-division code of the registration authority.
- Positions 9-17: the nine-character subject identifier based on the organization-code system.
- Position 18: check character.
The grouping is therefore 1 + 1 + 6 + 9 + 1. Positions 3-8 are not the company's full current address, and the final position is not an extra status flag. The official explanation also describes the code as unique and stable for the subject. Review the five-part explanation.
Who can have one?
The underlying national standard is titled for “legal entities and other organizations,” so USCC is broader than a private limited company number. The exact registration document and authority depend on the subject type. The national standards platform lists GB 32100-2015 as the current coding-rule record. Open the standard record.
A code is retained for traceability after a subject is cancelled; its continued existence therefore does not mean the organization is currently active. Search the code and record the returned Chinese legal name, subject type, status, and retrieval date.
Stable code, changing company facts
The code is the durable join key in a review file. Company facts around it can change: name, address, legal representative, shareholders, capital, business scope, and operating status all have their own effective dates and source records. A document from an earlier year may therefore carry the same USCC while showing an older name or address.
Do not “correct” the code merely because another field changed. Instead, use the USCC to search the subject, then compare the document date with the company's recorded change history. If two current documents show different USCCs, treat them as two entity candidates until the relationship is established.
Common misreadings
- “18-digit number”: inaccurate shorthand. A USCC can contain permitted uppercase letters as well as digits.
- “Registration number”: may refer to the USCC in casual correspondence, but historical documents can carry older identifiers.
- “Valid-looking means genuine”: false. Correct length or checksum does not prove issuance or ownership.
- “One code approves the supplier”: false. It anchors identity; status, ownership, capability, disputes, payment path, and product evidence require separate review.
How to use the field
Copy all 18 visible characters from the source document, preserve the original image, and search the full code. Then compare the returned Chinese name with the licence and transaction documents. For character rules and checksum calculation, use Validate a Chinese USCC. For the surrounding document, use Read a Chinese Business License.
