What is DealTunnel

DealTunnel ingests official business registries from 12 Latin American countries, normalizes them to a common schema, enriches them with decision-maker contact data, and serves them via REST API.

The dataset: 132,013,983 official records from public sources. 47.7M active business entities. 29.6M with phone declared at the source (92% from Brazil).

Sources by name: DENUE/INEGI (Mexico), RUES/Confecamaras (Colombia), CNPJ/Receita Federal (Brazil), SII (Chile), SUNAT (Peru), ARCA (Argentina), SRI (Ecuador), DNIT (Paraguay), DGII (Dominican Republic), DEI/RUPE (Uruguay).

If a field is missing for a country, this documentation says so. If contact data comes from enrichment rather than the original source, the record says so.

The numbers on this page were measured on July 12, 2026, by counting every row of every complete registry download. Each file has a provenance hash (SHA-256) linking it to the original public source.

The Pipeline

Four steps.

1. Download

Bulk download from public registries. CSV, ZIP, or API, depending on the country. Every source is free and publicly accessible. Every download produces a provenance hash: SHA-256 of the file, paired with the source URL and download date.

2. Ingest + Normalize

Raw records map to a common schema. Tax IDs (NIT, RFC, RUT, CNPJ) map to dt_id. Activity codes (CIIU, SCIAN) normalize to a unified classification. Company type, legal structure, registration status, and representative name come straight from the source. Fields that exist in one country but not another are null, not fabricated.

3. Enrich

Decision-maker contact data (email, phone, LinkedIn) via Clay. This step is manual, costs money, and runs on demand. A human operator exports a batch, runs it through Clay, and reimports the results. Every enriched field carries a source tag: clay, manual, or registry.

4. Serve

REST API with filters by CIIU code, city, country, and registration status. Full-text search on company name. CSV export with the same filters. Paginated responses, GZip compression, scoped API keys.

Coverage by Country

The table below shows exactly what each source provides.

*Colombia: the national RUES registry does not include contact data. Individual chambers (Ibague, Pereira) publish email/phone for their jurisdictions.

What the zeros mean

Chile, Peru, Argentina, Ecuador, Paraguay, and the Dominican Republic publish business registries without contact data. No phone. No email. The registries contain firmographic data only: legal name, tax ID, activity code, registration status, location.

Phone and email for these countries come exclusively from enrichment (Clay, directed search, voice verification). If the source does not carry the field, the table says 0%.

The Colombia mosaic

The national RUES registry from Confecamaras is a spine: company name, NIT, CIIU code, location, registration date. No phone, no email. But individual chambers of commerce publish their own data with full contact fields. Ibague and Pereira include email and phone for 100% of their records (113,630 combined). Contact coverage in Colombia varies chamber by chamber.

The Brazil concentration

27.2M of the 29.6M phone records across all 12 countries come from Brazil's CNPJ. Brazil's Receita Federal requires businesses to declare phone and email to the tax authority. Most Latin American registries do not.

A note on freshness

The DGII of the Dominican Republic deleted phone numbers from its public registry. Fields that existed in a previous download no longer exist. Sources change. DealTunnel timestamps every download and preserves historical snapshots. The data reflects what the source published at the time of download, not necessarily what it publishes today.

Schema

Company Object

Fields from the public source. Present for every record.

Enrichment fields

Null until the company goes through the enrichment pipeline.

Person Object

Exists only after enrichment. Linked to a company via company_id.
