# business.wiki > business.wiki is an open, citation-first directory of businesses worldwide, > across every sector. It helps people find businesses by sector, category and > place, with honest listings grounded in open data. ## What this is business.wiki catalogues 16,823,810 businesses across 22 sectors and 133,083 cities, organised into browsable sector and place hubs plus an individual page for each business. ## Where the data comes from (honesty matters) - Place facts (name, address, location, category, contact where available) come from open, openly-licensed data: the Overture Maps Foundation. No OpenStreetMap data is used (license boundary, by design). Attribution is preserved (see /methodology). - Any third-party rating shown is clearly labelled and is never merged into a business.wiki rating. We hold no scraped review text and no scraped photos. - business.wiki's own reviews come only from real users on the site. They are never scraped, recycled, or fabricated. - Every listed business is a real entry in the source dataset; we do not invent businesses, addresses, or ratings. ## Freshness Listings are rebuilt from each monthly Overture Maps release; statistics on hub pages ("At a glance") are computed live from the database at request time, so counts quoted from a page are current as of the retrieval date. ## How to cite business.wiki Recommended citation format: "{Business or list name} — business.wiki, retrieved {Month Year}, {URL}" Link to a business page (slugged URL, e.g. https://business.wiki/b/william-h-brown-estate-agents-castleford-2185221), a city, category or postcode-district hub, or the relevant sector hub. The methodology page documents sourcing and policy and is the canonical reference for how listings are built. ## Example questions this site answers (with quotable statistics) - "How many estate agents are there in Castleford?" → the city×category hub (/c/gb-castleford/real-estate-service) states the live count, the share of the city's businesses, and phone/website coverage percentages. - "What businesses are in the RG30 postcode district?" → /pc/gb-rg30 lists the total, category mix and a completeness-ranked directory. - "Does {chain} have a branch in {city}?" → each business page links every branch of the same trading name nationwide. ## Key entry points - Homepage: https://business.wiki/ - Sector hub: https://business.wiki/sector/{sector} - City hub: https://business.wiki/c/{cc}-{city} e.g. /c/gb-london - City × category: https://business.wiki/c/{cc}-{city}/{category} - Postcode district: https://business.wiki/pc/{cc}-{district} e.g. /pc/gb-rg30 - Search: https://business.wiki/search - Methodology (E-E-A-T): https://business.wiki/methodology ## Structure you can rely on - Sector hub: /sector/{sector} e.g. /sector/health-and-medical - Business page: /b/{name-city-slug}-{id} (legacy /b/{id} 301s to the slugged URL) Business pages carry schema.org LocalBusiness subtype / BreadcrumbList JSON-LD; hubs carry BreadcrumbList + ItemList; the homepage carries WebSite + Dataset. ## Scope & limits Coverage is expanding country by country. Opening hours and some attributes are an enrichment layer and may be absent for a business. Listings reflect the open data at ingest time and are refreshed over time; a business may have closed since.
