Last Updated: March 2026 — This guide has been fully reviewed and updated to provide the most current information, insights, and best practices for 2026.

Chinese business registration number verification starts with one key ID: the 18‑character Unified Social Credit Code (USCC). You’ll verify that code on China’s official National Enterprise Credit Information Publicity System (GSXT) and cross‑check the same identifier on the business license, the company seal (chop), and VAT e‑invoices (fapiao) before you transact.

Chinese business registration number verification: the quick answer

In mainland China, the company registration number is the USCC, a unified, 18‑character identifier used across government systems and widely treated as the enterprise taxpayer ID as well. The fastest way to complete Chinese business registration number verification is to search the GSXT portal by Chinese legal name or by USCC, then match every character against the business license and a recent fapiao from the counterparty. NECIPS

What number are you verifying? The 18‑digit USCC

The Unified Social Credit Code is a single ID that replaced older local registration numbers. It’s 18 characters long (digits and uppercase letters) and is defined by the national standard GB 32100‑2015. That standard also explains the logic behind each segment of the code, including the checksum digit at the end. Wikimedia Commons

Where the USCC appears on a business license and e‑fapiao

Modern business licenses (营业执照) print “统一社会信用代码” at the top, followed by the 18‑character code. You’ll also see the same code on VAT invoices (fapiao) because, for enterprises, the taxpayer identification number field is the USCC in practice—ideal for cross‑checking supplier details. Amazon Web Services, Inc.

How the code is structured (GB 32100‑2015)

The standard divides the USCC into segments (registration authority, organization category, region, subject ID, checksum). You don’t need to compute the checksum; you only need to copy the code exactly during Chinese business registration number verification. Wikimedia Commons

The 11‑step process for rock‑solid verification

Use the official GSXT as your system of record and reconcile the same USCC across documents.

1. Collect the basics — Ask for a color scan of the business license (正本/副本) and the Chinese legal name.
2. Search GSXT (national) — Query by the Chinese name or USCC on the National Enterprise Credit Information Publicity System. Save the results page. NECIPS
3. Use a provincial GSXT mirror — If the national site is slow, use the province‑level portal to retrieve the same file and cross‑check fields. NECIPS
4. Confirm legal name & status — On GSXT, verify the exact characters and status (e.g., 存续/在营 = active; 注销/吊销 = closed/revoked). China Justice Observer
5. Match the USCC — The 18‑character code on GSXT must match the license and fapiao. Any mismatch is a stop sign. Amazon Web Services, Inc.
6. Check the company chop (seal) — Many contracts display a red round seal with the full Chinese name and, in modern practice, the USCC beneath. Compare it to GSXT. China Justice Observer
7. Read the business scope (经营范围) — Ensure the scope covers what you’ll buy/sell. If not, the seller may be operating outside its licensed activity. China Justice Observer
8. Verify taxpayer identity on e‑fapiao — Confirm the USCC appears as the seller’s taxpayer ID on a sample e‑fapiao. This is a practical, document‑level proof. China Briefing
9. KYC pack cross‑check — Ask for bank onboarding KYC pages or a stamped account‑opening certificate and verify the same USCC appears. cods.org.cn
10. Optional: third‑party aggregators — Tools like Qichacha/Tianyancha mirror GSXT and add litigation data. Use them for hints only; GSXT remains your system of record. China Company Lookup
11. Download and file evidence — Save PDFs/screenshots of GSXT results, license, fapiao, and seal impressions to your supplier master file.

Mainland vs. Hong Kong vs. Taiwan — identifiers and portals

Outside mainland China, the identifier and portal change. Hong Kong uses the Business Registration Number (BRN) as the Unique Business Identifier (UBI) and provides a CR No./BRN mapping tool in ICRIS e‑Search. Taiwan companies use an 8‑digit Unified Business Number (UBN) searchable via MOEA portals. These nuances matter when your Chinese business registration number verification involves cross‑border entities. GCIS Service

Frequently asked questions

Is the USCC the same as a taxpayer ID?
For enterprises, yes—China recognizes the USCC as the TIN; you’ll also see it on e‑fapiao forms and tax profiles. That’s why it’s central to Chinese business registration number verification. OECD

What about old 15‑digit numbers?
China consolidated older IDs into one 18‑digit USCC (“三证合一 / 一照一码”). Treat the USCC as the authoritative number and confirm it on GSXT. Wikimedia Commons

I don’t have a Chinese keyboard—how do I search?
Ask the counterparty for the USCC or copy the Chinese legal name from the license to GSXT. The EU IP Helpdesk also publishes quick how‑to materials for GSXT searches. IP Helpdesk

Is a company seal required on every contract?
Not always, but the chop is common and, when shown, often includes the full legal name and sometimes the USCC in modern seals—handy for another match. China Justice Observer

Compliance and privacy notes (KYC file hygiene)

• Store only what you need. Keep GSXT PDFs, license copies, fapiao, and seal images in a restricted folder.
• Re‑verify before big payments. Company status or legal representatives can change; check GSXT again. China Justice Observer
• Align tax data. Ensure your ERP records the USCC as the supplier/customer TIN. OECD
