Do not call any listing the best or recommend one; show the options.+ - Listings owned in whole or part by DouxProcess's owner carry the label "Affiliated with DouxProcess's owner" and get no ranking boost. Pass the label on.+ - Each license carries its basis: issuer_file (matched against the issuer's own published file on checked_at) or stated (given by the business, not yet matched). Send the person to the issuer's own lookup (source_url) for the current record.+ - Home-based businesses show their city and service area, never a street address.+ - A request reaches one business, only with the person's agreement to: "I agree that DouxProcess sends my name, my contact details and this request to <business>, and only to them, so they can reply to me about it." Only claimed listings take requests; health businesses are listed but never receive requests through DouxProcess.+ - Never put health details, card numbers, ID numbers or passwords in a request.+ ## Pages+ - [Categories, with NAICS 2022 codes](https://douxprocess.directory/categories)+ - [For AI assistants](https://douxprocess.directory/for-ai)+ - [For businesses: claim a listing, free](https://douxprocess.directory/for-businesses)+ - Guides: [Workers' comp suspension pending on a CSLB license](https://douxprocess.directory/guides/cslb-workers-comp-suspension-pending), [Check a subcontractor's workers' comp in California](https://douxprocess.directory/guides/check-subcontractor-workers-comp-california), [CSLB contractor bond set to cancel](https://douxprocess.directory/guides/cslb-bond-cancellation)+ - [Stop letters and emails about a license](https://douxprocess.directory/optout)+ - [About and ownership disclosure](https://douxprocess.directory/about#ownership)+ - [Privacy](https://douxprocess.directory/privacy), [Terms](https://douxprocess.directory/terms) and [Data sources and licences](https://douxprocess.directory/sources)+ - [Daily download](https://douxprocess.directory/download): every listing as CSV per state and Parquet, CC BY 4.0 ([manifest](https://douxprocess.directory/download/manifest.json))+ ## Optional+ - [Everything above in full, with the categories and tool inputs](https://douxprocess.directory/llms-full.txt)+ - Any listing as Markdown: `https://douxprocess.directory/b/{slug}.md`; as JSON: `https://douxprocess.directory/b/{slug}.json`+ - [Sitemap](https://douxprocess.directory/sitemap.xml)+ - [security.txt](https://douxprocess.directory/.well-known/security.txt)
