LATAM Company Enrichment: tax ID and domain lookup, 7 countries

By LatSouth. Paste a list of CNPJ, RUT, NIT, RUC, CUIT, DENUE ids or company domains and get one row back per input: whether it matched, and the company's record from the official registries of Brazil, Mexico, Chile, Colombia, Peru, Argentina and Ecuador — legal name, status, legal form, ISIC Rev.4 industry in English, size, region, city, address, registration date, HTTP-verified website, public company contacts (BR, MX, CO) and government-supplier flags (BR, CO). Up to 10,000 inputs per run.

Company data only: no owners, partners, personal mailboxes or personal phones; e-mail inputs are echoed with the local part masked.

Price	US$0.01 per matched input (enriched-match) · US$0.001 per input not matched (no-match)

Use cases

• CRM enrichment: you have tax IDs (or website domains) in Salesforce/HubSpot and want legal name, status, industry, size and location in English, in one consistent schema across seven countries.
• KYB pre-check: is this CNPJ/RUT/NIT/RUC/CUIT valid (check digit), registered, active, private or public, a sole-owner entity? Does it win government contracts?
• Lead list cleanup: drop inactive, public-sector and sole-owner rows, normalize tax IDs, attach ISIC, find the company behind a domain and add its public role e-mail and phone.

Input

The Console form is prefilled with three lines (Petrobras by CNPJ, Ecopetrol by NIT, Pipefy by domain).

Mixed list, auto-detected

{
  "identifiers": ["33.000.167/0001-01", "CO:899999068-1", "pipefy.com", "77.552.777-3", "20100047218",
                  "30-70917199-9", "1790016919001"]
}

One country, ids without punctuation

{
  "identifiers": ["900272469", "860002964", "890903938"],
  "default_country": "CO"
}

API: your own reference, tax ID with domain fallback, no gov flags

{
  "records": [
    {"tax_id": "11.222.333/0001-81", "domain": "acme.com.br", "ref": "crm-001"},
    {"domain": "https://www.empresa.mx", "ref": "crm-002"}
  ],
  "include_gov_flags": false
}

Field	What it does
identifiers	One per line (max 10,000): tax IDs in any punctuation, CC: prefix optional (CO:900593229), or a domain / URL / e-mail
default_country	Country for unprefixed ids; AUTO (default) tries every country whose format fits
records	API objects {tax_id, country, domain, ref}; ref is echoed as input_ref; the domain is the fallback when the tax ID is not found
include_contacts	Public company contacts for BR/MX/CO (default true)
include_gov_flags	Government-supplier flags for BR/CO (default true)

Accepted identifiers

Country	Identifier	Formats	Check digit
Brazil	CNPJ (establishment), or the 8-digit root → head office	12.345.678/0001-95, 12345678000195, 12.345.678, alphanumeric CNPJ	modulo 11 (Receita, incl. 2026 alphanumeric rule)
Mexico	DENUE establishment id	6190221	none — the RFC is not published by INEGI (unsupported_id); use the domain
Chile	RUT	77.552.777-3, 77552777-3, 775527773, DV K	modulo 11
Colombia	NIT	900.593.229-1, 900593229 (with or without DV)	DIAN weights
Peru	RUC 20	20100047218	modulo 11
Argentina	CUIT	30-70917199-9, 30709171999	modulo 11
Ecuador	RUC (sociedad)	1790016919001	modulo 11 (reported only: ~21% of SRI company RUCs fail it)
all	domain	acme.com.br, https://www.acme.mx/x, ventas@acme.co, subdomains	free-mail, ISP, social and placeholder domains are rejected

Without a country, an id is looked up in every country whose format fits; when it exists in two (e.g. an 8-digit number that is a Colombian NIT and a Mexican DENUE id) the row is ambiguous with candidate_tax_ids — add the prefix.

Fields that a country does not publish are null (contacts and gov flags are null outside their countries, false when the country has data but the company has none). The run's OUTPUT record has status counts, matches per country, timings and the dataset releases used.

How matching works

• Tax IDs are normalized (punctuation, spreadsheet-dropped leading zeros, Colombian DV stripped), validated, and looked up only in the countries they can belong to (one partition per country).
• Domains match a company when its registry website, HTTP-verified website or registered corporate e-mail uses that domain (exact first, then the parent domain). Brazil groups establishments by CNPJ root (the head office is returned) and Mexico by legal name; when several companies use the domain, the one whose own HTTP-verified website it is wins; otherwise (groups, agencies, accountants' domains) the row is ambiguous and lists up to 10 candidates. Domains are searchable for Brazil (1.49M establishments / 756k domains), Mexico (359k / 139k) and Colombia (22k / 18k); Chile, Peru, Argentina and Ecuador publish no website or e-mail, so look those up by tax ID. Large companies often register an accountant's e-mail: domain matching finds them only when their own domain is on the registry.
• Public contacts come from the company's own homepage and ship only when the domain belongs to that single company (not shared, not an accountant's), e-mails are role mailboxes on that domain, and phones are in the country's numbering plan. Coverage: BR 167,866 establishments, MX 78,920, CO 7,517.
• Government suppliers: 369,754 suppliers with contracts (Brazil PNCP 2025-01 to 2026-10: 268,216; Colombia SECOP II: 101,538), matched on the exact tax ID.

Pricing

Pay per event, charged per output row:

Event	When	Price
enriched-match	the input matched exactly one company	US$0.01
no-match	not found, ambiguous, invalid or unsupported	US$0.001

1,000 inputs with a 70% match rate cost US$7.30. Duplicate inputs are returned once. Set a maximum cost per run and the actor stops when it is reached (OUTPUT.stopped_by_budget).

Sources, licences and attribution

Every matched row carries its registry's credit in source and source_license; keep them when you publish the data: Receita Federal do Brasil — Dados Abertos CNPJ · INEGI, DENUE 05/2026 (Términos de Libre Uso) · Chile RES (CC BY) + SII nómina · Confecámaras RUES + Superintendencia de Sociedades (CC BY-SA 4.0: Colombian rows and derived works must be shared alike) · SUNAT Padrón RUC (ODC-BY 1.0) · Registro Nacional de Sociedades (CC BY 4.0) · SRI Catastro RUC (CC BY 4.0). Government contracts: PNCP (Lei 14.133/2021, "Fonte: PNCP") and SECOP II, Agencia Nacional de Contratación Pública - Colombia Compra Eficiente (datos.gov.co jbjy-vk9h, CC BY-SA 4.0); the credit is in gov_source. Public contacts: LatSouth, from each company's public homepage. Full texts per country: see the LATAM Company Finder README.

Limitations

• Mexico has no RFC in INEGI's open data: enrich Mexican companies by DENUE id or domain.
• Natural persons, MEI / individual entrepreneurs (BR), personas físicas (MX), RUC 10 (PE) and closed CNPJs are not in the registries we publish, so they come back not_found (by design).
• Brazil's website_verified is an HTTP check (2xx/3xx, not parked); other countries have no verified websites.
• Argentina has no company status (is_active is null; see status); Peru has no registration date; Ecuador has no street address.
