Argentina Company Finder: CUIT, Registro Nacional de Sociedades

By LatSouth. Search 1.27 million Argentine companies (1,269,627 CUITs) from the Ministerio de Justicia's Registro Nacional de Sociedades (data supplied by ARCA): filter by province, locality, CLAE / ISIC Rev.4 activity and incorporation date, and get CUIT, legal name, legal form, address and zip code with English industry labels. Unlike the CUIT lookup tools, this one searches by segment.

Company data only: no partners, directors, e-mail or phone.

Rows	1,269,627 CUITs · 1,171,126 with an active tax activity, private, not sole-owner (the default filters)
Data as of	2026-09-18 snapshot; every row carries data_as_of
Price	US$0.003 per company returned: 1,000 companies = US$3
Typical run	about 5 s on the platform (prefilled example 4.7 s; 100 CABA software companies since 2020 5.4 s)

Who it's for

• Sales teams entering Argentina: "software companies in CABA incorporated since 2020", "manufacturers in Córdoba and Santa Fe", "SAS registered in 2025".
• Market sizing: OUTPUT.total_matching counts the segment even if you pull a sample.
• Enrichment: start from a segment and feed CUITs, names and addresses to your CRM.

Limitations

• No company status: the registry does not say whether a company is active, so there is no is_active field. only_active keeps companies with at least one active tax activity (status = active_activity, 95% of rows) — a weaker signal than a registry status; dissolved companies can still pass it.
• ISIC coverage is ~68%: 28% of companies still carry a pre-2013 AFIP code with no ISIC mapping (a strong "dormant" signal). The native code is always in activity_code_local.
• No size or workers and no trade name, e-mail, phone or website are published.
• Sociedades unipersonales (SAU) and sociedades simples have masked names and are excluded by default.

Pricing

Pay per event: company-result, US$0.003 per company row returned (1,000 = US$3). Set a maximum cost per run and the actor stops when it is reached (OUTPUT.stopped_by_budget). Full files and custom segments: https://latsouth.com/data/argentina/.
