USCI: Unified Social Credit Identifier for Chinese Suppliers
How to use the USCI (Unified Social Credit Identifier) to verify Chinese phone suppliers — what the 18-digit code reveals and where to look it up.
USCI (Unified Social Credit Identifier) is an 18-character alphanumeric code assigned to every registered business in China. Phone buyers can verify a Chinese supplier's USCI at the National Enterprise Credit Information Publicity System (gsxt.gov.cn) to confirm: legal business name, registration status (active or deregistered), registered capital, legal representative, and any administrative violations or court blacklist flags. A supplier who cannot provide their USCI should be treated with high caution.
What USCI Is
The Unified Social Credit Identifier (统一社会信用代码, USCI) is China’s single 18-character business registration code, mandatory for all legally registered enterprises since 2015. Before the reform, Chinese companies held separate identifiers issued by different authorities — an Organization Code from the Technical Supervision Bureau, a Tax Registration Code, and a Business License number from the Administration for Market Regulation (AMR). The USCI replaced all three, consolidating them into one persistent identifier that follows the entity for its entire lifespan.
For B2B buyers, the practical consequence is straightforward: any legitimate Chinese supplier registered after 2015 — and any legacy entity that completed re-registration — has exactly one USCI. If a supplier cannot produce this code, or produces one that does not match their business license, treat it as a red flag.
Structure of the 18-Digit Code
The USCI is not random. Each position encodes registration metadata:
| Position | Length | Meaning |
|---|---|---|
| 1 | 1 digit | Registration authority (1 = SAMR/AMR; 2 = Civil Affairs; 9 = others) |
| 2 | 1 digit | Entity type (1 = enterprise; 2 = public institution; 3 = social org; 9 = others) |
| 3–8 | 6 digits | Administrative division code (province/city/county) |
| 9–17 | 9 characters | Organization code (alphanumeric) |
| 18 | 1 character | Check digit |
For wholesale phone suppliers, position 1 should be 1 (AMR-registered) and position 2 should be 1 (enterprise). A supplier claiming to be a trading company with a USCI starting with 9 warrants scrutiny.
How to Look Up a Supplier on gsxt.gov.cn
The National Enterprise Credit Information Publicity System (国家企业信用信息公示系统) at gsxt.gov.cn is the authoritative public registry. The interface is Chinese-only. Steps:
- Go to gsxt.gov.cn
- Paste the supplier’s company name (in Chinese characters) or their 18-digit USCI into the search box
- Select the matching result — verify the full legal name matches the name on their business license exactly, including punctuation
- Review the record detail page
If you do not read Chinese, use the browser’s built-in translation or copy the company’s Chinese name from their business license or contract header before searching.
What to Check in the Record
Once you have the record, verify these fields before placing an order:
| Field | What to Look For |
|---|---|
| 登记状态 (Registration status) | Must read 正常 (normal/active). 注销 means deregistered; 吊销 means license revoked |
| 经营范围 (Business scope) | Should include phone trading, electronics, or communications equipment (通讯设备, 手机, 电子产品). A company outside this scope is not licensed for phone trade |
| 注册资本 (Registered capital) | Cross-reference against the order value — a company with RMB 100,000 registered capital quoting $500,000 orders is a mismatch worth probing |
| 法定代表人 (Legal representative) | Note the name; it should match the signatory on any contract |
| 成立日期 (Incorporation date) | Trading companies incorporated within the last 12 months carry higher counterparty risk for large orders |
| 行政处罚 (Administrative penalties) | Any entries here indicate prior regulatory action — review the detail |
The AMR record also shows whether the company has been placed on an abnormal operation list (经营异常名录) for failure to file annual reports — a common indicator of dormant or nominee-held shells.
Matching USCI to the Business License
Request a copy of the supplier’s Business License (营业执照) as part of standard onboarding. The USCI printed on that document must match the code in the gsxt.gov.cn record exactly. Discrepancies — even a single transposed digit — may indicate a forged document or a different legal entity.
Also confirm:
- The registered address on the license matches the gsxt record
- The company name is identical character-for-character (Chinese legal names are case- and punctuation-sensitive)
- The license has not passed its validity date, if one is shown
Limits of USCI Verification
USCI lookup confirms that a legal entity with that registration exists and is in good standing with the AMR. It does not confirm:
- That the company actually ships phones of the quality quoted
- That the individual you are communicating with is authorized to represent the company
- That the registered address is an active operating location
Treat USCI verification as a necessary first filter, not a complete due diligence pass. Follow it with trade reference checks from prior buyers, a sample order before any large commitment, and escrow or letter-of-credit terms for high-value transactions.
