Korea Business Directory (Official SEMAS Store Data)

Get an official list of South Korean shops, restaurants, cafes, clinics, salons, academies and other small businesses as clean JSON / CSV / Excel. Each row is a store registered in the commercial district database of the Small Enterprise and Market Service (SEMAS, 소상공인시장진흥공단), a government agency, compiled from National Tax Service and card company data.

Type a district (Gangnam-gu, Seoul, 서울 강남구), a whole province (Busan), or a point and radius, pick categories in plain English (Cafe, Korean cuisine, Hair salon) and get every matching business with its address, floor and GPS coordinates. No scraping of private websites: the data comes from the official public data API.

What you can use it for

• Market sizing and site selection: count cafes, pharmacies or gyms per district or within 500 m of a location before opening a store.
• Competitor mapping: list every business of a category around a point, with coordinates ready for a map or GIS tool.
• Lead lists for B2B sales: all hair salons in Jeju, all dental clinics in Seoul, all restaurants in a neighborhood (names and addresses; see the note on phone numbers below).
• Data enrichment: join on business_id, road address, building management number or coordinates.
• Research and AI agents: a consistent, English-labelled national business register for South Korea.

Pricing

Pay per result: $1 per 1,000 businesses. You only pay for rows saved to the dataset after filters.

Good to know

• No phone numbers, opening hours or reviews: the official dataset does not contain them. If you need them, use this list as the base and enrich it.
• Data month: the source publishes the database as of a reference month, shown in data_month on every row. Businesses that opened or closed after that month may be missing or still listed.
• Names and addresses are in Korean as registered. name_romanized and neighborhood are mechanical romanizations (Revised Romanization), not official English names. Categories, sectors, provinces and districts are in English.
• Floors: floor is a number (negative for basements) when the source gives one; the original text is kept in floor_ko.
• 2026 administrative changes (for example the Jeonnam-Gwangju merger) follow the source's current codes. Inputs like Gwangju still work.
