The 9 Best B2B Data Providers in Spain: Filed, but Paywalled (2026)

Spain does something specific with its company data: it requires the accounts to be filed, then keeps them behind a toll booth. Every capital company must deposit its annual accounts at the Registro Mercantil, so the financials genuinely exist, but the register is not open data. Extracts and filed accounts are paid, priced by a fixed government tariff, and channelled through the registrars. What you buy from a provider is the work of structuring, scoring and reselling what sits behind that wall.

One name has dominated that work for thirty years, Informa D&B, and there is a twist worth knowing before you shortlist anyone: in 2023 the competition authority fined Informa D&B and Moody's for running a price-fixing and customer-sharing cartel on their shared financial databases. Around them sit an insurer-owned bureau, an Experian-backed challenger and the free gazette that anyone can build on.

This guide ranks {count} providers on merit. We sell Spanish business data ourselves, so our pitch sits in a marked box rather than at number one.

In a hurry? The short answer

Jump to a provider

1. Informa D&B: the incumbent

The dominant Spanish provider, and the exclusive route to the D&B file in Spain and Portugal.

Founded in 1992 and wholly owned by the state export-credit insurer CESCE, Informa D&B is the reference for Spanish business information: commercial, financial and marketing data on Spanish, Portuguese and Colombian businesses, plus the global D&B file it holds exclusive rights to distribute in Iberia. It is the default first call for Spanish credit and risk. One caveat to carry into any comparison: it was fined by the competition authority in 2023 over its shared financial databases.

3. eInforma: the self-serve portal

Informa's freemium shop, and the easy way to pull the odd Spanish report without a contract.

eInforma is Informa D&B's online self-serve brand, offering free basic reports on registration and a few free detailed pulls before you pay per report or buy a discounted pack. For a professional who needs an official Spanish report now and then rather than a data feed, it is the practical middle ground between the free gazette and a full Informa contract. Same underlying data as Informa, packaged for occasional buyers.

4. Iberinform: the insurer's bureau

Credit risk seen through a credit insurer's eyes, which is a genuinely different and useful lens.

Iberinform belongs to Grupo Catalana Occidente through the credit insurer Crédito y Caución, and that heritage shows: its commercial, financial and predictive data is tuned to spotting payment default before it happens, informed by an insurer's real claims experience. It covers Spain and Portugal with international reach on top. For credit and risk teams, the insurer lineage is the reason to shortlist it alongside Informa.

5. Axesor: the Experian-backed challenger

Since joining Experian, the one that can blend Spanish business data with consumer-credit signals.

Founded in 1996, Axesor was acquired outright by Experian in early 2021, and it now sits inside Experian's Spanish operation. That combination lets it pair business information and scoring with Experian's consumer-credit data, which Experian markets as a uniquely combined proposition in Spain, useful when a young business has no track record of its own. Credit, risk, fraud and marketing intelligence, with a global parent behind it.

6. SABI: the analyst's file

The Iberian equivalent of Orbis: deep structured accounts for modelling, not a prospecting tool.

SABI holds structured financial statements on around three million Spanish and roughly a million Portuguese businesses, built from the deposited accounts, and is the file Spanish analysts and universities reach for. It is co-produced by Bureau van Dijk, now Moody's, and Informa D&B, and sold in Spain as part of the Informa stable. Note it was one of the databases named in the 2023 cartel ruling. Built for financial analysis and benchmarking, not for building outreach lists.

7. Camerdata: the chambers' file

The chambers of commerce prospecting file, official-source and built for marketing rather than risk.

Owned by the Spanish chambers of commerce, Camerdata sells the Fichero de Empresas Españolas: more than four million businesses and self-employed, built from the chambers' census and enriched with Registro Mercantil and BORME data, refreshed quarterly. It is a prospecting and marketing file with an official-source pedigree, which is its main selling point over a compiled list. Not a credit or financial source.

8. Deyde DataCentric: the marketing and geodata house

Where you go for data quality, geomarketing and enrichment rather than a business report.

Now part of Grupo Tinsa and merged with the data-quality firm Deyde, DataCentric sells B2B and consumer marketing data, geo-referenced business listings, data cleansing and enrichment. Its strength is turning messy address and firmographic data into something usable and geolocated, which is a different job from assessing a counterparty. For prospecting, segmentation and cleaning a Spanish CRM, it is a strong specialist.

9. Kompass España: the export directory

A product-classified directory for industrial and export prospecting, long-established in Spain.

Kompass has run in Spain since the 1960s, classifying around 2.8 million Spanish businesses across 67 sectors by a detailed product and service taxonomy, with the EasyBusiness prospecting tool on top. For finding every Spanish maker or supplier of a specific product, or building an export list, that taxonomy beats a plain activity code. It is directory data rather than register or financial data, so shortlist it for prospecting only.

How Spanish company data ended up behind a wall

Spain opened its gazette but kept the register paid, and the commercial market consolidated around that arrangement, right up to a competition scandal:

So who is still actually Spanish?

Spain kept its prospecting and chambers data local, while the credit end is split between a state insurer, a mutual insurer and a global group:

Deposited but not open: how Spanish data works

Spanish capital companies must deposit their annual accounts at the Registro Mercantil within a month of approval, so the financials exist for the vast majority of incorporated businesses. The catch is access. The register is not open data: extracts and filed accounts are paid, at a fixed tariff set by the Ministry of Justice with no discounts, and delivered through the registrars rather than downloaded in bulk. That paywall is the moat every commercial provider monetises.

There is one genuinely free layer. BORME, the official gazette, publishes incorporations, appointments and account-deposit notices as open data with an API, so you can track new-business signals and build a base file for nothing. What BORME does not give you is the financials themselves, or scoring, or contacts. Check the primary sources here:

• Registradores de España : The official paid channel for register extracts and deposited annual accounts, at a fixed government tariff.
• BORME : The official gazette: incorporations, appointments and account-deposit notices, free with open data and an API.
• INE DIRCE : The statistics office business directory: free aggregated counts for market sizing, not individual records.

Four questions before you sign anything

1. Do you need the accounts, or a score, or a list? The deposited accounts are available from the registrars for a fixed fee. What a bureau adds is scoring, monitoring and analytics on top. If you only need the occasional official report, the registrars or eInforma beat a full Informa or Iberinform contract.

2. Do you want a genuine second opinion? Informa and SABI share data and were the subject of the 2023 ruling, so pairing them is not a true second view. Iberinform, owned by a credit insurer, and Axesor, backed by Experian, give you independent lenses on the same businesses.

3. Is the free gazette enough for your base layer? BORME is free, open and has an API. If you need new-business signals and basic registration facts rather than financials or scores, you can build a lot on BORME before paying anyone.

4. Do your targets actually deposit accounts? Capital companies deposit; the self-employed and simplest structures do not. If your market is the long tail of autónomos, financial depth will be thin no matter who you buy from, and a prospecting file like Camerdata may fit better than a bureau.
