Company Database Poland 2026 — Sources Comparison

"Company database Poland" is a phrase every B2B salesperson, accountant seeking clients, and startup founder building outbound types into Google in 2026. The problem is that the same term hides completely different products: from the free CEIDG register, through bulk GUS files, to specialized new-registration aggregators.

In this article we compare all significant sources of company data in Poland — by freshness, completeness, cost, legality, and prospecting usefulness. At the end you will find a decision table for "which source for which purpose".

Poland's Company Data Landscape — Source Map

Poland's registration system is fragmented. There is no single "central database of all companies" — there are registers with different legal roles:

Each source answers a different question. CEIDG says "who opened a hair salon in Poznań yesterday". KRS says "who is CEO of a company with 5M capital". REGON says "what is the entity's statistical number". None alone is a complete "company database Poland" — aggregation and filtering create a useful sales product.

CEIDG — Foundation of B2B Prospecting in Poland

Central Registration and Information on Business (CEIDG) is the most important source for anyone seeking new companies. In 2026 CEIDG contains:

entrepreneur name,
business start date,
PKD codes (main and additional),
registered office and correspondence address,
entry status (active, suspended, deleted),
link to full entry.

CEIDG advantages as company database:

Free access to public data.
Highest freshness for JDG — entries appear on registration day.
Precise PKD codes enable industry segmentation.
Business start date as natural sales trigger.

Operational disadvantages:

No convenient bulk export for non-technical users.
Contact data (email, phone) appears only when entrepreneur provides it — often missing.
Search interface not optimized for building prospecting lists.
Deletions and suspensions require regular filtering.

For sales departments CEIDG is raw material, not a finished product. Hence aggregators like nowe-firmy.pl that daily pull new entries, filter by PKD and region, and deliver ready CSV files.

KRS — Corporate Entity Database

National Court Register (KRS) covers limited liability companies, joint-stock companies, limited partnerships, and other commercial law entities. Data includes:

share capital,
management composition and representation,
shareholders,
entry and change history,
registered office and branches.

When KRS is the best source:

B2B sales to companies with formal corporate structure.
Contractor verification before large agreements.
Ownership and capital link analysis.
Identifying SPVs in real estate and finance.

When KRS is not enough:

Prospecting micro-businesses and freelancers (that is CEIDG).
Fast reach on "registration day" (KRS process takes weeks).
Mass outbound to mass market (restaurants, local services, JDG e-commerce).

In 2026 roughly 80% of new business entities in Poland are JDG in CEIDG. A company database based solely on KRS covers a minority of new registrations by volume.

REGON and GUS Data — Statistical Layer

REGON Register, maintained by Statistics Poland (GUS), assigns a REGON number to every business entity. REGON links to CEIDG and KRS — it is an identification layer, not an operational one.

What REGON provides:

Verification that entity exists in statistical register.
Data on legal form and formation date (with some delay).
Links to local units (branches, establishments).

What REGON does not provide conveniently:

Daily feed of new registrations with PKD filter.
Contact data for prospecting.
Intuitive interface for salespeople.

GUS also publishes entrepreneurship statistics — e.g. number of newly registered entities monthly and regionally. Invaluable for market planning (how many companies register monthly in Poland?) but not for building contact lists. More in: how many new companies register monthly in Poland.

Bulk GUS / REGON Files

"GUS company databases" sold as CSV files with millions of records circulate on the market. In 2026 worth knowing:

Bulk data is often delayed by weeks or months.
No prioritization of "newly registered" — you get everything including deleted companies.
High share of stale contacts — even 30–50% email bounce rate.
Low purchase price, but hidden cost is cleaning time and domain reputation.

Sensible for data analysts and GIS. Disappointing for new company prospecting.

VAT White List and Industry Registers

Though not "company databases" in prospecting sense, worth including in comparison:

VAT Taxpayers White List — VAT status and bank account verification. Mandatory before every larger B2B transaction.

CRBR (Central Register of Beneficial Owners) — beneficial owner data. Key for AML, not cold outreach.

Industry registers (e.g. KNF for finance) — niche but precise in their domain.

Commercial Aggregators — Product Layer

Official registers deliver legal truth. Commercial aggregators deliver productivity. Compare main business models in 2026:

Model 1: Contractor verification (InfoVeriti, similar)

Deep KRS analysis, links, risk.
Monitoring corporate structure changes.
Expensive packages, target: compliance, collections, corporate accounting.
Weaker in daily new JDG feed.

Model 2: KRS-centric (KRS.online, similar)

Fast access to corporate data.
Useful in mid-market and enterprise B2B sales.
Does not cover JDG — majority of market.

Model 3: CEIDG-centric / new registrations (nowe-firmy.pl)

Daily pull of new CEIDG entries.
Filtering by PKD, voivodeship, city, registration date.
CSV export, email delivery, CRM-ready.
Optimized for prospecting and lead generation.
Contact data enrichment when available in register.

Model 4: International platforms (Apollo, ZoomInfo)

Good Western market coverage.
Variable Polish micro-business coverage.
High cost, LinkedIn integration.
Supplement, not CEIDG replacement.

Data Quality — How to Evaluate a Company Database in Practice

Not every "company database Poland" is equal. Here are 6 metrics to measure before purchase or source selection:

1. Freshness

How many days from company registration to appearing in database? In B2B prospecting every day of delay is lost advantage — a competitor may be first. CEIDG and daily-sync aggregators beat bulk GUS files.

2. Contact Fill Rate

What percentage of records have email or phone? In CEIDG entrepreneurs need not provide contact — typical fill rate is 20–40%. An aggregator that honestly reports this metric beats one promising "full databases with phones".

3. PKD Accuracy

Does industry filter work on main (predominant) code or all additional codes? A company with main PKD "programming" and additional "gastronomy" is a different lead than a restaurant with additional "IT".

4. Survival Rate

How many companies on the list are still active after 30, 60, 90 days? New JDG have natural churn — some suspend in first months. Good database filters deletions.

5. GDPR Compliance

Where does data come from? Is processing lawful? Public registers (CEIDG, KRS) are safe sources. "Databases bought on marketplace" — risky. Read: new company contact data — legal GDPR methods.

6. Cost Per Lead (CPL)

CPL = (database cost + labor time) / qualified conversations. Cheap databases with 50% stale data often have higher real CPL than expensive but fresh CEIDG source.

Decision Scenarios — Which Source to Choose?

"I need 100 new leads monthly in industry X in region Y"

Choice: nowe-firmy.pl (CEIDG aggregator).

Rationale: Official registers require too much manual work. Bulk GUS files are stale. InfoVeriti/KRS.online do not optimize for this use case.

"I verify a contractor before a 200,000 PLN agreement"

Choice: KRS + VAT White List + InfoVeriti (optional).

Rationale: Due diligence depth matters, not registration freshness.

"I build market analysis — how many companies in Poland, regional trends"

Choice: GUS / stat.gov.pl + REGON.

Rationale: Statistical data, not contact lists. See new company statistics Poland 2026.

"I have zero budget and lots of time"

Choice: Manual CEIDG + Google Sheet.

Rationale: Works at 5–10 leads daily. Does not scale above ~50 without automation.

"I sell to mid-market limited companies"

Choice: KRS.online + LinkedIn Sales Navigator + nowe-firmy.pl for JDG transitioning to company.

Rationale: Hybrid stack covers both segments.

2026 Trends — What Is Changing in Company Databases

Prospecting automation. Sales teams increasingly connect CEIDG database with Make.com/n8n and CRM (Pipedrive, HubSpot). CSV export from nowe-firmy.pl → webhook → CRM is standard pipeline.

AI in outreach personalization. Database is fuel; AI is engine. LLMs generate personalized openers based on PKD and city — but only if input data is fresh and accurate.

Tighter GDPR and UODO practice. Buying "email databases" without provenance is growing risk. Public registers + legal B2B outreach is safer path.

Regional segmentation. Instead of "all Poland", teams target 2–3 voivodeships. Region filtering becomes must-have — more in article on new companies by voivodeship.

Death of mass, impersonal cold email. With inbox saturation, whoever reaches first with relevant offer wins — and that requires fresh CEIDG data, not old GUS file.

How to Build Your Own Company Data Stack

Recommended stack for agency or B2B sales department in 2026:

Prospecting layer: nowe-firmy.pl — daily feed of new JDG with PKD and region filter.
Verification layer: CEIDG + VAT White List — before every larger transaction.
Corporate layer: KRS — when lead transitions to limited company.
Analytics layer: GUS/stat.gov.pl — market planning and targets.
Compliance layer: Internal GDPR policy + opt-out in outreach.

This stack costs a fraction of full InfoVeriti package and covers 90% of typical B2B sales team needs in Poland.

Summary — Company Database Poland 2026

There is no single "best company database in Poland" — there is best fit for purpose:

KRS — source of truth for companies, due diligence foundation.
REGON/GUS — statistical and analytical layer.
Bulk files — cheap but costly in cleaning and freshness.
nowe-firmy.pl — sales-ready product: daily new CEIDG companies, filtered and exportable.

If your goal is B2B client acquisition among newly registered companies, start with the prospecting layer. Check nowe-firmy.pl and compare data quality with what you have today — the fastest ROI test.

FAQ — Frequently Asked Questions

1. How does a company database differ from CEIDG register?

CEIDG is official public register — legal source. Company database is usually commercial product built on registers (CEIDG, KRS, REGON), with additional filtering, export, and often data enrichment.

2. Are GUS company databases legal?

REGON itself is public, but processing and use (e.g. in cold email) must comply with GDPR. Bulk files bought from intermediaries without clear provenance carry legal risk.

3. Which source has freshest new company data?

CEIDG — entries appear on registration day. Aggregators syncing with CEIDG daily (e.g. nowe-firmy.pl) offer comparable freshness in ready-to-use format.

4. Can I use KRS data for cold calling?

KRS data is public, but phone contact requires GDPR legal basis (e.g. legitimate interest in B2B context) and compliance with do-not-call rules for consumers — different regulation than B2B.

5. How much does a professional company database in Poland cost?

From 0 PLN (manual CEIDG) to hundreds–thousands PLN monthly (InfoVeriti, international platforms). nowe-firmy.pl offers subscription model optimized for prospecting — much cheaper than enterprise due diligence.

6. Is it worth combining multiple sources?

Yes. Recommended stack: nowe-firmy.pl (prospecting) + CEIDG/KRS (verification) + GUS (analytics). Each source covers a different stage of sales process.
