Using the Unified Social Credit Code to identify a company
The credit code anchors a Mainland entity match. Its format helps detect transcription errors, but only the registry confirms which entity it identifies.
By Matthew Lee
The Unified Social Credit Code (统一社会信用代码) is the most useful anchor for matching a Mainland company across documents. Names can change, and English renderings vary, while the identifier ordinarily remains with the entity. An onboarding reviewer should use the code to locate the record, then compare that record with the contract and customer-provided evidence.
What the code contains
The State Council’s 2015 code-system plan and national standard GB 32100-2015 establish an 18-character identifier. Beijing market-regulator guidance explains the department and category codes and the permitted character set. The structure is useful for spotting transcription problems and understanding a historical record, but it is not a substitute for a registry match.
| Position | Meaning | How to use it |
|---|---|---|
| 1 | Registration department | Understand which registration framework issued the identifier |
| 2 | Entity category within that department | Check whether the recorded form fits the customer’s description |
| 3–8 | Registration authority’s administrative division | Treat as encoded registration context, not proof of today’s address |
| 9–17 | Entity identifier derived from the organisation code | Help reconcile older organisation-code evidence |
| 18 | Check character | Detect some transcription errors |
The permitted alphabet excludes I, O, Z, S and V. A character outside that set or a failed check calls for correction against the source document. Passing a format or check-character test does not establish registration, current status or ownership. A fabricated string can have a plausible format, so the official record remains the identity evidence.
Why it is preferable to a name-only match
The code-system rules are designed around one entity and one identifier. Ordinary changes such as a new address or legal representative do not create a new identity. Deregistration also does not make the identifier available to a new namesake. This lets the reviewer preserve continuity through a name change and distinguish an ended company from another business with similar branding.
Some structural conversions can be treated as a new entity under the code framework. Where a customer presents a different code, the reviewer therefore needs the supporting registration or restructuring evidence rather than an assurance that the business has always used the same brand. The contract, payment beneficiary and records should identify which legal person now takes the obligations.
Reconciling historical numbers
Before the registration reforms, company records could carry separate business-registration, organisation and tax identifiers. An older 15-digit registration number can therefore be legitimate historical evidence without being the right key for a current company search. Ask for the present licence and code, then retain the documents connecting the old and new references.
Store the identifier as text, preserving all characters, and label tax or administrative numbers separately. This prevents spreadsheet formatting or an unlabeled invoice reference from corrupting the later search. The licence guide explains the other fields to compare, and the China onboarding guide covers the wider evidence file.
Requesting the evidence by email
An approved organisational sender can email agent@fill-easy.com with the Chinese legal name, Unified Social Credit Code, requested evidence and case reference. For example:
Please obtain current registry evidence for [Chinese name], Unified Social Credit Code [code]. The older document shows [historic number]. Reference: [case]. Include a referenced summary and identify any evidence needed to connect the records.
The agent clarifies ambiguous matches or unavailable items and confirms access, availability, price and turnaround at acceptance. PDFs arrive in the same thread with source, retrieval time and request ID; an optional summary cites the records. The reviewer assesses the evidence and decides.
