Chinese company registration number search is simpler than it looks. In mainland China, the number you need is the 18‑character Unified Social Credit Code (USCC). You can find it on the National Enterprise Credit Information Publicity System (the official registry), on a company’s business license, and on VAT invoices (fapiao) and other formal documents. SAMR

Chinese company registration number search: the quick answer

For mainland entities, the company registration number is the USCC, an 18‑digit/letter code that uniquely identifies a legal entity across government systems. The fastest route is to search the National Enterprise Credit Information Publicity System (NECIPS/GSXT) by Chinese name or by USCC. The USCC also appears on the business license next to “统一社会信用代码”. SAMR

What number are you looking for? Meet the 18‑digit USCC (Unified Social Credit Code)

China replaced older local registration numbers with a single 18‑character ID for each entity. The USCC sits at the core of your Chinese company registration number search and is used across company filings, tax, customs, and many public records. Standards Info Platform

Where it appears on the business license

Official samples of licenses that embed the USCC show “统一社会信用代码” at the top of the document; every modern business license displays it. If a supplier sends you a scan/copy of the license (正本 or 副本), the USCC is printed prominently. Government of China

What the 18 characters mean (standards overview)

The USCC is defined by GB 32100‑2015. In brief, the 18 characters encode the registration authority type, entity category, administrative region code, a subject identifier, and a check digit. In practice, you don’t need to calculate it—just copy it exactly when you search or invoice. Wikimedia Commons

Step‑by‑step: 9 ways to find a Chinese company registration number

Use multiple methods to cross‑check. Your Chinese company registration number search should end with an exact 18‑character USCC that matches the name, status, and address on file.

#1 — Search the official GSXT portal (NECIPS)

Go to the National Enterprise Credit Information Publicity System and search by company Chinese name. The result page shows the USCC (统一社会信用代码), status (e.g., 存续/在营), legal representative, address, and establishment date. Tip: if the national portal is busy, try again during off‑peak hours or use provincial mirrors. SAMR

#2 — Try a provincial GSXT mirror if the national site throttles

Each province exposes the same core dataset under the GSXT framework. If the central page is slow, use the province where the company is located to pull the same USCC and filings. SAMR

#3 — Match by exact Chinese name (and city)

Chinese legal names are case‑sensitive by character and often include the city (e.g., “上海××有限公司”). Ensure the Chinese name in contracts matches the GSXT entry character‑for‑character to avoid a wrong Chinese company registration number search hit. IP Helpdesk

#4 — Read the business license

Ask the counterparty for a color scan of the latest business license. Locate “统一社会信用代码” at the top and copy the 18 characters. Compare name, legal rep, and address to GSXT. The license format showing USCC placement is standardized by official guidance. Government of China

#5 — Use a VAT e‑invoice

The seller’s taxpayer identification number on a VAT invoice for enterprises is the USCC in almost all modern cases—so the code on a recent fapiao is a reliable cross‑check. (China’s tax documents and forms explicitly reference the employer’s unified social credit code.) fgk.chinatax.gov.cn

#6 — Check contracts, seals, and chops

Many contracts list the USCC near the signature block or under the red company seal. If present, confirm it against GSXT before you process payments or ship goods. Government of China

#7 — Third‑party databases (for convenience only)

Well-known platforms (e.g., Qichacha) aggregate GSXT data and may also include litigation/credit information. Use them to triangulate, but trust the official GSXT for the final Chinese company registration number search result. China Justice Observer

#8 — Bank KYC packs and onboarding forms

Banks in China collect the USCC during onboarding. If your counterparty provides a bank KYC pack, the USCC will typically be on the account opening forms or compliance sheets (matching the license and GSXT). mr.samr.gov.cn

#9 — Ask for it directly (and verify)

A genuine partner will share their USCC readily. Always verify the 18 characters and the exact Chinese name on GSXT and reconcile with the license before contracting. SAMR

How to read the record you find (and common red flags)

When your Chinese company registration number search returns a company page:

• Check status: 存续/在营/开业 = active; 注销/吊销 = closed/revoked.
• Match the legal representative: Should match the license and contracts.
• Confirm address & scope: Ensure the business scope covers what you’re buying.
• Cross‑check dates: Establishment and latest annual filing should make sense for the deal size.
• Red flags: frequent changes of legal representative, abnormal operations, administrative penalties, or mismatched addresses. GSXT shows such notes. SAMR

FAQ: old 15‑digit numbers, multiple numbers, and translation issues

Q1: I received a 15‑digit “registration” number—valid?
China’s reforms consolidated IDs into the 18‑digit USCC. Today, enterprises use the USCC as the primary identifier; legacy numbers are retained only in historical documents. Always convert/verify via GSXT. Standards Info Platform

Q2: Is the taxpayer identification number the same as USCC?
For enterprises that have the modern business license, yes—the enterprise’s taxpayer ID generally equals the USCC, and tax forms reference “taxpayer identification number / unified social credit code.” Verify against invoices and GSXT. fgk.chinatax.gov.cn

Q3: I can’t type Chinese. How do I search?
Ask the counterparty for the USCC or the exact Chinese legal name. You can also copy/paste it from the license. Some third‑party tools provide pinyin/English entry, but confirm on GSXT. China Justice Observer

Q4: Do Hong Kong companies have a USCC?
No. Hong Kong uses BRN as the Unique Business Identifier and has a separate registry (ICRIS). Use the CR No./BRN mapping function to cross‑reference identifiers. Inland Revenue Department Hong Kong

Compliance & next steps: verify, document, and monitor

1. Capture evidence: Save a PDF/screenshot of the GSXT record and the business license with the USCC visible. SAMR
2. Reconcile identifiers: Ensure USCC on license, fapiao, contracts, and chops match. Government of China
3. Monitor changes: Re‑check GSXT before major payments/shipments (rep changes, status changes, penalties). SAMR
4. Build a file: Keep copies of fapiao (seller/buyer IDs), bank account proofs, and KYC forms tied to the USCC. fgk.chinatax.gov.cn
5. Get local help: If language or regional issues slow your Chinese company registration number search, a local advisor can complete the verification and provide a memo. See FDI China’s services for entity checks, setup, payroll, and filings.
