Methodology
The Slovak company database is built from public registers, chamber directories, business directories and the details companies publish themselves. Here we describe what we take from which source, how we link contacts to an IČO and where the limits are.
Database status: 3 November 2026 · Page updated: 3 November 2026
As of 3 November 2026 the database holds 2,415,912 entities, 1,257,168 of them active. It draws on these public sources: the Register of Legal Entities (RPO), lists of the Financial Administration (tax ID, VAT ID, tax reliability index), the register of financial statements via Ekosystém Slovensko.Digital, business directories (zlatestranky.sk, zoznam.sk, azet.sk), Overture Maps and OpenStreetMap map data, lists of professional chambers and authorities, lists of healthcare providers, sector portals and company websites. Record counts by source are on the database status page.
The identity of entities from the register: IČO, business name, address, legal form, main SK NACE activity code and dates of incorporation and dissolution. The RPO takes over data from the commercial, trade and other registers. The register is governed by Act No. 272/2015 Coll.; its open data is available as bulk files under the CC BY 4.0 licence. The register contains no contact details.
Published lists of taxpayers and VAT payers and the tax reliability index: tax ID, VAT ID and the tax reliability rating. We do not use lists whose licence prohibits commercial use.
Processed open company data, including size categories from the register of financial statements; we comply with the provider’s terms.
Public lists, for example of lawyers, architects, civil engineers, hauliers or healthcare providers. Contacts on them are published for professional purposes; for individuals the GDPR obligations apply.
The zlatestranky.sk, zoznam.sk and azet.sk (so far as a pilot) directories and sector portals such as podnikam.sk, where companies publish their contacts. We store the source address for every contact. Directories may be protected by the database maker’s right, so we keep their data separate from register data.
Open map data with premises, names and contacts (Overture under the CDLA Permissive 2.0 licence, OpenStreetMap under the ODbL). We link a contact to an IČO only via a verified website or a matching name and address; premises that cannot be linked to an IČO are kept as separate businesses without an RPO record.
Phone numbers, email addresses and websites that companies publish together with their identification details; under § 4(1) of Act No. 22/2004 Coll., an information society service provider must state, among other things, its business name, registered office, email, phone and register entry. We process company websites so far as a pilot.

The figures on this website are measured directly in the production database as of 3 November 2026, without rounding:
Tables by status, region and source are on the database status page.
Alongside our own figures we show market size according to official statistics. Slovakia: Eurostat, structural business statistics (sbs_ovw_act), businesses in industry, construction and market services in 2024: 682,029 (NACE sections B to S excluding O and S94, reference year 2024, data as of 30 September 2026); the same source provides the figures by industry. EU: EU-27 33,978,235, of which 33,296,206 in the 26 other member states. Municipalities: Eurostat, local administrative units (LAU) 2024. The Statistical Office of the Slovak Republic supplies the Slovak data to Eurostat under the common EU methodology. Official statistics count enterprises, not register entries, and cannot be compared directly with the number of RPO entries or with our dataset. We were unable to open the Statistical Office’s own website (DATAcube) on 25 October 2026, so we cite Eurostat.
This is how a record of the Slovak company database is created. Data from other countries is compiled for each request (EU and other markets).
Matching is automated and cannot be error-free. For identical or very similar names without an IČO on the website, the risk of a wrong match is higher.
Many industries have official lists, such as the register of financial agents, chamber directories or the register of hauliers. They are for checking whether a particular company is authorised and are not contact lists for marketing. What exists in each industry is described on the industry pages:
More about the registers: Slovak business registers: what is public and SK NACE industry codes. On outreach rules: B2B outreach and § 116.
If you find incorrect data in your own record, write to us and we will correct it.
Data in public registers is kept by the relevant register. We correct our record; a permanent correction also requires a change in the register.
The database status page shows which figures we publish, always with a date and source.
