Best B2B Data Providers in Latin America: 5 Regional Options (2026)

Latin America is a study in contrasts. Brazil publishes its entire company register as a free download and has one of the world's richest open-data ecosystems, while Mexico has no public register at all. Argentina, Colombia, Chile and Peru sit somewhere in between, each with its own registry and its own rules. The region also has two powerful domestic credit-bureau markets (Brazil's Serasa/Boa Vista/Quod and Mexico's Buró/Círculo) that do not cross borders.

The cross-border problem in Latin America is harder than in Europe or North America. Few providers cover the whole region with genuine depth, and the ones that do are often reselling D&B data or aggregating from patchy local sources. This guide covers {count} providers that are genuinely useful across Latin American markets.

We sell Latin American business data ourselves, so our pitch sits in a marked box.

In a hurry? The short answer

Jump to a provider

1. CIAL Dun & Bradstreet: the regional D&B partner

The only provider with structured business-information coverage across 40+ Latin American markets.

CIAL Dun & Bradstreet is the D&B partner for Latin America, covering 40+ markets with D-U-N-S numbering, business credit reports, compliance screening and supplier risk management. For cross-border work that spans Brazil, Mexico, Colombia, Argentina, Chile and smaller markets, CIAL is the only provider with genuinely structured, multi-country coverage tied to the global D&B file. It is the default for compliance and supply-chain risk in the region.

3. Serasa Experian (Brazil): Brazil's credit giant

Dominant in Brazil, with the deepest CPF/CNPJ infrastructure in Latin America. Not a regional player.

Serasa Experian is Brazil's largest credit bureau and the anchor of Experian's Latin American operation. Its coverage of Brazilian businesses via CNPJ infrastructure is unmatched, and it provides credit reports, scores, monitoring, fraud prevention and compliance tools. For Brazil specifically, Serasa is the default first call. For the wider region, Experian's network extends through other Latin American markets, though depth drops off sharply outside Brazil.

4. BigDataCorp: Brazilian data-tech at scale

The leading Brazilian data-tech firm, scraping the open register and building enrichment at scale.

BigDataCorp built its business on Brazil's open company data, scraping the Receita Federal register and layering verification, enrichment and compliance tools on top. It covers 57M+ Brazilian CNPJs and offers APIs for KYB, onboarding and lead generation. For Brazilian data-tech at scale, BigDataCorp and Neoway are the two local leaders. Coverage outside Brazil is limited.

5. Neoway: Brazilian analytics and compliance

Advanced analytics and compliance on Brazilian company data, recently acquired by B3 (the stock exchange).

Neoway provides analytics, compliance and data-intelligence tools built on Brazilian company and individual data. Acquired by B3, the Brazilian stock exchange, it has a strong compliance and fraud-prevention positioning. For Brazilian KYB, due diligence and risk intelligence, Neoway competes with BigDataCorp and Serasa from a data-analytics angle. Like BigDataCorp, it is Brazil-focused.

How Latin America's data landscape shaped up

Each market developed independently, from Brazil's open-data boom to Mexico's opacity:

The Latin American data landscape

Brazilian locals dominate Brazil, CIAL D&B bridges the region, and domestic bureaus handle credit:

Open in Brazil, opaque everywhere else

Brazil is the anchor of Latin American business data. The Receita Federal publishes the entire CNPJ register as a free quarterly download, making it one of the most open company-data ecosystems in the world. Every Brazilian entity carries a CNPJ, the equivalent of a European company number, and the data includes activity codes, address, legal form and partner names.

The rest of the region is harder. Mexico has no public register, Argentina publishes some provincial data, Colombia and Chile have partial registries, and smaller markets vary widely. For any cross-border work, a provider like CIAL D&B or a business-data platform that has already done the aggregation is far more practical than trying to stitch together a dozen national sources. Here are the key official starting points:

• Receita Federal (Brazil) : Brazil's full company register, published as a free quarterly download keyed on CNPJ.
• DENUE (Mexico) : Mexico's free directory of economic units, a statistical tool rather than a company register.
• CIAL D&B : The Dun & Bradstreet partner for Latin America, covering 40+ markets with D-U-N-S numbering.

Three questions for Latin American data

1. Brazil only, or the wider region? If you only need Brazil, the local providers (Serasa, BigDataCorp, Neoway) are strong and mature. For multi-country work across Latin America, CIAL D&B or a business-data platform like ours is more practical.

2. Credit, compliance, or prospecting? For credit: Serasa in Brazil, Buró de Crédito in Mexico, CIAL D&B across the region. For compliance and KYB: Neoway or CIAL D&B. For prospecting and contact data: BigDataCorp in Brazil or a multi-country platform like ours.

3. How much can you invest in integration? Brazilian data-tech firms offer powerful APIs but require Portuguese-language integration. CIAL D&B provides a more standardised English-language interface. A business-data platform like ours gives you one API for the whole region. Match the integration effort to your team's capacity.
