Croatia Company Lookup: The Register Publishes People

A Croatia company lookup runs through the sudski registar, the court register, kept by the trgovački sudovi — the commercial courts. The Ministarstvo pravosuđa, uprave i digitalne transformacije runs the system and the open-data portal. The register is at sudreg.pravosudje.hr and the developer portal at sudreg-data.gov.hr. This guide covers what the register publishes, when a registration counts as published, and how the data is reached programmatically. If you need the Croatian population rather than one company at a time, the Croatia company directory covers the same registered entities with industry, size and contact breakdowns attached, and the Croatia business database is the same file described as a dataset.

Croatia company lookup: the short version

• The Ministry describes the sudski registar as a public book containing authentic and up-to-date data and documents on the entities the law requires to register.
• Registered data about natural persons is publicly available by their OIB — showing the entities in which the person is or was registered, their functions, and the periods in which they held them.
• Registration data is published without delay once the decision is final, and is deemed published at the end of the day of website publication.
• The open-data API returns XML or JSON over REST only, updated daily, and requires registration — a Client ID and Client Secret after account verification.

The register publishes the person-level view

Most registers in this series publish companies and let you find people inside them. Croatia publishes the view from the other direction, and says so plainly:

"Na internetskoj stranici javno su dostupni upisani podaci o fizičkim osobama prema njihovom OIB-u na način da je vidljiv popis subjekata u kojima je osoba upisana (ili je bila upisana), njezine funkcije i razdoblja u kojima ih je obavljala."

On the website, registered data about natural persons is publicly available according to their OIB — the personal identification number — in such a way that what is visible is the list of entities in which the person is registered (or was registered), their functions, and the periods in which they performed them.

Read the three components, because each adds something. Not just current entities but former ones. Not just presence but function. And not just function but the period it was held. That is a career in the register, retrievable from one identifier.

This is a transparency design, and it should be read as one rather than as an oversight. The register's own description of itself is "javna knjiga koja sadrži vjerodostojne i ažurne podatke i isprave o subjektima upisa za koje je upis u registar propisan onim zakonima koji uređuju ustroj i djelovanje određene pravne osobe" — a public book containing authentic and up-to-date data and documents on the entities for which registration is prescribed by the laws governing that legal person's organisation and operation. A register built as a public book, holding authentic data, publishing the person view, is coherent with itself.

Norway answers the same question the other way

What makes this worth a page rather than a paragraph is that another EU state, working from the same underlying material, reached the opposite position.

The Norway company lookup guide covers a register whose API documentation states: "Opplysninger om at en person er registrert med en rolle, som for eksempel styremedlem, er åpne offentlige data. Men ønsker du å sette opp en oversikt over hvilke roller en person har i andre virksomheter, har du kun lov å vise roller knyttet til næringsvirksomhet" — that a person holds a role is open public data, but an overview of a person's roles across other undertakings may only show roles connected to commercial activity, citing § 9-1 of the enhetsregisterloven.

So: Norway publishes the roles and restricts the combined view by statute. Croatia publishes the combined view. Same raw material, opposite answers on aggregation.

Neither is better and this page does not say otherwise. Nor does it generalise about EU practice — two states is two states, and a direction drawn from two points is invention rather than observation. What it does establish is narrow and useful: the person-level question has no common European answer, so anyone building a cross-border process around role data needs each country's own position rather than a rule of thumb.

The publication moment is precise

For anyone monitoring Croatian companies for change, the important sentence is about timing rather than content:

"Podaci o upisu u registar objavljuju se na internetskoj stranici na kojoj se nalazi registar bez odgađanja po pravomoćnosti rješenja o upisu u registar i smatraju se objavljen istekom dana objave upisa na internetskoj stranici."

Data on registration is published on the website where the register is located without delay once the decision on registration becomes final, and is deemed published at the expiry of the day on which the registration is published on the website.

Two distinct moments, and the second is the legal one. Publication happens without delay after finality; the data is deemed published at the end of that day. A monitoring process that treats the moment a record appears as the moment it counts is using a timestamp the rule does not use.

Another register in this series puts its legal clock somewhere else entirely. The Switzerland company lookup guide covers a system where the cantonal offices transmit entries to the federal office, which checks, approves and forwards them to the gazette — and "Die Einträge werden Dritten gegenüber erst mit der Publikation im SHAB rechtswirksam": entries become legally effective against third parties only upon publication in the SHAB. Switzerland's clock runs on a gazette publication; Croatia's runs to the end of the day of website publication. Two states, two answers to when does this count, both written down — and a process built on one will misdate the other.

What a Croatian company register entry contains

A self-contained summary. Croatia's company register is the sudski registar, kept by the trgovački sudovi — the commercial courts — with the system and open-data portal run by the Ministarstvo pravosuđa, uprave i digitalne transformacije. The Ministry describes it as a public book containing authentic and up-to-date data and documents on the entities for which registration is prescribed by the laws governing that legal person's organisation and operation. Registered data about natural persons is publicly available on the website according to their OIB, showing the list of entities in which the person is or was registered, their functions, and the periods in which they performed them. Data on registration is published on the website without delay once the registration decision becomes final, and is deemed published at the expiry of the day on which it is published on the website. Registration proceedings before the court are initiated by filing an application as a publicly certified document, or as an electronic application and electronic submission filed electronically by a notary or a HITRO.HR office. The legal basis is the Zakon o sudskom registru, Narodne novine 1/1995 through 40/19, with subordinate regulation in the Pravilnik o načinu upisa u sudski registar, NN 121/19. The Ministry states the update frequency as daily and the access method as open data, and that data from the sudski registar can be downloaded in machine-readable form in XML or JSON format exclusively by calling the REST API interface. The open-data portal is intended for developers who wish to take sudski registar data into their own applications in machine-readable form; access requires registration, and on verification the user receives a Client ID, a Client Secret and a token link giving access to the REST API endpoints, with technical questions going to sudski.registar@pravosudje.hr. The e-Usluge sudskog registra service enables two-way electronic communication with the commercial court and is integrated with NIAS, the national identification and authentication system, for natural persons and business users, Croatian and EU/EEA. This summary does not describe the fields of a register entry, or the terms on which the search itself is offered, because neither was established from the Ministry's own pages on the date shown.

The API is open data behind a registration

Croatia's programmatic route is documented, and the shape of it is worth stating exactly because it differs from the licence-based openness elsewhere in this series.

The Ministry's open-data inventory gives the mechanics: "Učestalost ažuriranja: svakodnevno. Način pristupa: otvoreni podaci. Podatke iz Sudskog registra moguće je preuzeti u strojno čitljivom obliku (XML ili JSON format isključivo pozivom RESTapi sučelja)." Update frequency: daily. Access method: open data. Data can be taken in machine-readable form in XML or JSON, exclusively by calling the REST API interface.

And the portal states who it is for and what it requires: "Portal otvorenih podataka Sudskog registra namijenjen je razvojnim inženjerima koji u svoja aplikativna rješenja žele preuzimati podatke Sudskog registra u strojno čitljivom obliku. Za pristup podacima potrebno je napraviti registraciju." — intended for developers who want to take the data into their own applications, and access requires registration. On verification the user receives a Client ID, a Client Secret and a token link giving access to the REST API endpoints. Technical questions go to sudski.registar@pravosudje.hr.

So it is described as open data and it is reached through an account. Nothing read here states any rate limit, volume cap or condition of reuse, and this page states none — those are exactly the terms a reader would want and they are not sourced.

The legal basis is named in the same inventory: the Zakon o sudskom registru, Narodne novine 1/1995 through 40/19, with subordinate regulation in the Pravilnik o načinu upisa u sudski registar, NN 121/19.

Where a Croatia lookup stops

Data reaches the register through two routes, and both are worth knowing because they explain the finality rule above. Registration proceedings before the court are initiated by filing an application as a publicly certified document, or as an electronic application and electronic submission filed electronically by a notary or a HITRO.HR office. The e-Usluge sudskog registra service enables two-way electronic communication with the commercial court and is integrated with NIAS, the national identification and authentication system, for natural persons and business users, Croatian and EU/EEA.

This page describes no field of a register entry. It also does not state the terms on which the public search itself is offered — whether it is free, and whether it needs an account. That is the most basic fact a reader wants and it was not established from the Ministry's own pages, so it does not appear. CROATIA_REPORT.md flags it first. What this page describes is what the register publishes, not what it costs.

Where the question is a population rather than a company, a firmographic directory covers the same registered entities with classification, size and contact data attached and queryable as a set; the Europe company directory breaks the European file down by market.

Data quality pitfalls to avoid in Croatia

Treating the appearance of a record as the moment it counts. Registration data is deemed published at the expiry of the day on which it is published on the website, not at the instant it appears.

Reading a person's entry as current-only. The OIB view shows entities in which the person is or was registered, with the periods held.

Assuming another country's aggregation rules apply. Croatia publishes the combined person view; at least one other EU state restricts it by statute, and there is no common answer to carry across borders.

Expecting a format other than XML or JSON. The Ministry states the data is taken in machine-readable form exclusively by calling the REST API interface.

Planning API access without an account. Access to the open-data portal requires registration, and credentials are issued on verification.

Assuming anything about API limits or reuse terms. None is sourced here; treat them as unknown rather than as absent.

A repeatable Croatia company lookup workflow

1. Search by OIB when you are starting from a person, and expect former roles as well as current ones.
2. Record the function and the period alongside any person-to-entity link.
3. Date any change against the end of the day of website publication, not the moment you saw it.
4. Register for the open-data portal before planning any programmatic work, and expect Client ID and Client Secret.
5. Request XML or JSON over the REST interface; no other route is stated.
6. Confirm the terms of the public search independently, because this page does not establish them.

Frequently asked questions

Can I look up a person in the Croatian register?

Yes. The Ministry states that registered data about natural persons is publicly available on the website according to their OIB, showing the entities in which the person is or was registered, their functions, and the periods in which they performed them.

Does that include past roles?

Yes — the wording covers entities in which the person is registered or was registered, with the periods in which the functions were performed.

When does a Croatian registration count as published?

It is published without delay once the registration decision becomes final, and is deemed published at the expiry of the day on which it is published on the website.

What is the sudski registar?

The Ministry describes it as a public book containing authentic and up-to-date data and documents on the entities for which registration is prescribed by the laws governing that legal person's organisation and operation.

Is there an API?

Yes. Data can be taken in machine-readable form in XML or JSON format, exclusively by calling the REST API interface, with daily updates. Access requires registration, and verified users receive a Client ID, a Client Secret and a token link.

Are there rate limits?

Nothing read for this guide states any. Treat limits and reuse terms as unknown rather than absent.

How do filings reach the register?

By an application filed as a publicly certified document, or as an electronic application and electronic submission filed electronically by a notary or a HITRO.HR office.

Source Register

Every Croatian sentence quoted above is the publisher's own wording, read on the date shown, carrying its diacritics as written, with an English gloss beside it rather than in place of it. No amount appears anywhere in this page's prose.

This page does not state whether the public search is free or whether it requires registration, because neither was established from the Ministry's own pages. That is the most basic fact about a company-lookup page and its absence is the first item in CROATIA_REPORT.md. The page describes what the register publishes, not what it costs.

The readings that are InfobelPRO's rather than the Ministry's: that the person-level view is a transparency design and should be read as one rather than as an oversight; that the three components of it — former entities, function, period — together amount to a career retrievable from one identifier; that the deemed-publication rule means a monitoring process keyed to the moment a record appears is using a timestamp the rule does not use; and that the person-level question has no common European answer, so a cross-border process needs each country's own position. Those are ours. The comparisons with Norway and Switzerland are comparisons of published rules, offered without ranking and without any claim about EU practice generally.
