Validates and decodes China’s 18-character Unified Social Credit Code offline (format and check digit only; does not confirm the company exists).

Tool description as the model sees it

Offline validator and decoder for China’s 18-character Unified Social Credit Code (统一社会信用代码, GB 32100-2015) — the single identifier every registered Chinese organization (company, social organization, government institution) carries. Checks the format (length, allowed 31-character set, and the GB 32100-2015 check-digit algorithm) and, when valid, decodes the registration authority (e.g. Market Regulation for an ordinary company), the entity type, and the province from the 6-digit administrative-division segment. No network call — this is a pure offline algorithm plus small public lookup tables (GB/T 2260 province codes), so it works for any syntactically plausible code, including ones that do not exist. Answers “is this a valid Chinese company code”, “decode this unified social credit code”, “check digit for 9111000012345678AU”, “which province does this USCC belong to”. IMPORTANT: this validates FORMAT ONLY — a format-valid code is not proof a real company holds it; confirming existence requires a live registry lookup this tool does not perform (see format_only_note in every response).

Name	Type	Required	Description
`code`	string	yes	The 18-character Unified Social Credit Code to validate, e.g. “9111000012345678AU”. Case-insensitive; surrounding whitespace is trimmed.
