Triage, Verification
A structurally valid code does not confirm a live entity, document authenticity, ownership, registered scope, operating location, or transaction eligibility.
Extract the full code from the source document, validate its structure, search the same code in the official registry, compare name and status in Chinese, and corroborate addresses, ownership, scope, and transaction claims separately.
The checker is available in English, Spanish, and Portuguese, but authoritative company records are commonly in Chinese and require accurate original-language interpretation.
Limits
Strengths, caveats, and risk
Free, browser-local calculation; explains every field; publishes test notes and source references; clearly separates checksum validity from company verification.
Does not query a live registry, validate the full administrative division, translate records, or establish the commercial facts behind a supplier claim.
A valid check digit does not prove the code was assigned to the named company, that the company is active, or that a document or transaction is genuine.
A copied or deliberately recomputed code can pass, and mistranslation or name mismatch can still connect the code to the wrong entity.
Registry interpretation, supplier approval, sanctions, customs, export, and contractual decisions require current primary records and qualified jurisdiction-specific review.
Preserve the original-language source and verify the same code in an authoritative registry before relying on entity status, scope, ownership, or location.
