How to Check a Chinese Company Registration Number

1. Identify the number on the business licence

Look for 统一社会信用代码, the Unified Social Credit Code. It contains 18 letters and digits. Do not confuse it with a telephone number, tax invoice number, organization code, or a marketplace account identifier.

2. Search the identifier and compare the Chinese name

Enter the full code without spaces. The returned Chinese legal name should match the licence, contract, and invoice. Compare the registration status, province, address, and legal representative before accepting the match.

3. Treat old registration numbers carefully

A legacy registration number may still help locate a historical record, but the current USCC is generally the better matching key. If documents show different identifiers, ask for a current business licence and verify why they differ.

4. Remember what the number cannot prove

A correct registration number identifies a legal entity. It does not prove that a website, salesperson, bank beneficiary, or supplier listing belongs to that entity.

Common questions

How many characters are in a Chinese USCC?

A Unified Social Credit Code has 18 letters and digits. Copy every character exactly as shown on the current business licence.

Is a Chinese registration number the same as a USCC?

Not always. The USCC is the current unified identifier, while older records may contain a separate legacy registration number.

Can two Chinese companies share the same USCC?

No valid current entities should share one USCC. If a search appears to show a conflict, recheck the characters and the source date.
