Greece Company Lookup: The Register Knows the Website

A Greece company lookup runs through the Γενικό Εμπορικό Μητρώο — Γ.Ε.ΜΗ., the General Commercial Registry, Greece's national register of commercial publicity. The Central GEMI Service sits with the KEEE; the General Secretariat of Commerce is the ministry side. The free search, Δημοσιότητα ΓΕΜΗ, is at publicity.businessportal.gr; certificates run through services.businessportal.gr; and there is an open-data API at opendata.businessportal.gr. This guide covers what a Greek register record carries, how the search behaves across two alphabets, and what the register says it wants third parties to do with the data. If you need the Greek population rather than one company at a time, the Greece company directory covers the same registered businesses with industry, size and contact breakdowns attached, and the Greece business database is the same file described as a dataset.

Greece company lookup: the short version

• The free record carries fields most registers do not hold at all: the company's website and e-shop, its financial data, the history of its trade names, and its EUID.
• The search covers both active and deleted businesses required to register in Γ.Ε.ΜΗ., with filters for legal form, status and activity.
• Text search runs across spellings and across the Greek and Latin alphabets — ανεξαρτήτως ορθογραφίας και χρήσης ή μη λατινικών χαρακτήρων.
• The Central GEMI Service publishes a documented open-data API whose stated purpose is that anyone interested can build third-party services on the data.

A register record that knows the company's website

Greek register records carry a field list that is unusual in this series, and gov.gr sets it out directly:

"ο αριθμός ΓΕΜΗ, το EUID, οι διακριτικοί τίτλοι και το ιστορικό τους, η επωνυμία με λατινικούς χαρακτήρες, ο ΑΦΜ, η ημερομηνία σύστασης, η νομική μορφή, η τρέχουσα κατάσταση, τα στοιχεία επικοινωνίας της, αλλά και στοιχεία της ιστοσελίδας και e-shop της· τα στοιχεία του κεφαλαίου της, της δραστηριότητας της καθώς και της διοίκησης της· τα οικονομικά στοιχεία της επιχείρησης και το ιστορικό ανακοινώσεων της στο ΓΕΜΗ."

The Γ.Ε.ΜΗ. number, the EUID, the distinctive titles and their history, the name in Latin characters, the ΑΦΜ (tax identification number), the date of formation, the legal form, the current status, its contact details, and also details of its website and e-shop; details of its capital, its activity and its management; the financial data of the business and the history of its announcements in Γ.Ε.ΜΗ.

Two entries in that list are worth stopping on, because a reader will not expect them: ιστοσελίδα and e-shop — the company's website and its online shop.

A Greek register record links the legal entity to its web presence. That join — this registered company is that domain — is one most data work has to construct from outside, by matching names, addresses or inference, and it is a join that is wrong often enough to matter. Here it is a field.

One caution belongs immediately beside it, and it is a caution about what the source actually says. gov.gr states that these details are in the record. It does not say that every company has them, how complete the field is across the population, or how current any given entry is. This page states the field exists and stops there; assuming coverage from the existence of a field is exactly the inference that produces confident, wrong data work.

The same discipline applies to τα οικονομικά στοιχεία — the financial data. Its existence is sourced: gov.gr lists it among what the search returns. What it contains, and for which entity types, is not. The page says the record includes financial data as listed by gov.gr, and says no more than that.

Searching across two alphabets

Greek company names live in two scripts. A business is registered in Greek and trades internationally in Latin transliteration, and transliteration is not standardised — the same name can be spelled several defensible ways.

The register handles it, and the wording is specific. The free Δημοσιότητα search supports text that "έξυπνα κάνει αναζήτηση σε Επωνυμίες και Διακριτικούς Τίτλους, ανεξαρτήτως ορθογραφίας και χρήσης ή μη λατινικών χαρακτήρων" — it intelligently searches company names and distinctive titles, regardless of spelling and of whether or not Latin characters are used.

Anyone who has tried to match Greek company data against Greek company data knows why that matters. The failure mode without it is silent: a search returns nothing, and nothing looks like absence rather than like a spelling difference. A register that absorbs the variation removes a whole class of false negatives — and note that the field list above separately carries η επωνυμία με λατινικούς χαρακτήρες, the name in Latin characters, as a stored field in its own right.

The same search supports criteria including seat details — postcode, city, prefecture and region — activity by one or more ΚΑΔ with hierarchical organisation across several levels, and date ranges for formation, closure and ΚΑΚ issuance. The ΚΑΔ hierarchy is a workflow fact worth knowing before you start: activity search is not a flat code match but a tree you can query at the level you want.

Deleted businesses are in the search itself

gov.gr states: "Μπορείτε να αναζητήσετε τόσο τις ενεργές όσο και τις διαγραμμένες εμπορικές επιχειρήσεις που είναι υπόχρεες σε εγγραφή τους στο ΓΕΜΗ." You can search both active and deleted commercial businesses required to register in Γ.Ε.ΜΗ. Advanced filters include legal form, status and activity. Results can be saved locally as a PDF: "Τα αποτελέσματα της αναζήτησης έχετε δυνατότητα να τα αποθηκεύσετε τοπικά σε αρχείο μορφής pdf."

Another register in this series keeps the past reachable in a different place. The Poland company lookup guide covers a register where deleted data sits inside the full extract — choosing the odpis pełny rather than the odpis aktualny is what surfaces struck-out entries. Greece puts deleted businesses in the search itself, as a population you can filter to. Two registers, two ways of keeping the past reachable: one in the document, one in the query. Neither is better, and the practical difference is only where you have to remember to look.

What a Greek company register entry contains

A self-contained summary. Greece's company register is the Γενικό Εμπορικό Μητρώο (Γ.Ε.ΜΗ.), the national register of commercial publicity; the Central GEMI Service sits with the KEEE and the General Secretariat of Commerce is the ministry side. The free publicity search, Δημοσιότητα ΓΕΜΗ, is at publicity.businessportal.gr, where the General Secretariat states that publishable data and information on businesses registered in Γ.Ε.ΜΗ. are made available publicly and free of charge; services.businessportal.gr separately handles certificate requests, application tracking, and authenticity checks on GEMI certificates and announcements. Per gov.gr, the search returns the Γ.Ε.ΜΗ. number, the EUID, the distinctive titles and their history, the name in Latin characters, the ΑΦΜ, the date of formation, the legal form, the current status, contact details, details of the website and e-shop, details of capital, activity and management, the financial data of the business, and the history of its announcements in Γ.Ε.ΜΗ. Both active and deleted commercial businesses required to register in Γ.Ε.ΜΗ. can be searched, with advanced filters including legal form, status and activity, and search results can be saved locally as a PDF. The free search supports criteria including seat details of postcode, city, prefecture and region, activity by one or more ΚΑΔ organised hierarchically across several levels, date ranges for formation, closure and ΚΑΚ issuance, and free text that searches company names and distinctive titles regardless of spelling and of whether Latin characters are used. The Central GEMI Service provides a developer interface giving access to GEMI data, making publicly accessible data of a GEMI record available as it is in Δημοσιότητα ΓΕΜΗ, with the stated purpose of providing open data from GEMI through a well-documented API so that any interested party can develop third-party services using it. Through the European e-Justice Portal, company information can be searched across the EU national commercial registers that have developed interconnectivity, GEMI included, as well as Iceland, Liechtenstein and Norway, using the company name and commercial register number. This summary states that the record includes financial data as listed by gov.gr; what that field contains, and for which entity types, was not established from the sources read on the date shown.

The EUID is a field you can read

Among the fields gov.gr lists is the EUID — the European unique identifier.

That deserves naming because of what it is for. The EUID is the identifier defined for the interconnection of European business registers, and its purpose is cross-border: one identifier that means the same company in more than one national system. Most discussion of it is about the plumbing. Here it is a field on a free record.

The interconnection is reachable in the other direction too: through the European e-Justice Portal you can search company information from the EU national commercial registers that have developed interconnectivity — GEMI among them — as well as Iceland, Liechtenstein and Norway, using the company name and commercial register number.

For a reader assembling data across European countries, those two facts together are the practical point: Greece publishes the cross-border identifier on the record you can already see, and the portal that consumes such identifiers reaches Greece.

An API whose purpose is third-party services

Registers vary a great deal in how they feel about other people building on their data. Greece writes its position down:

"Η Κεντρική Υπηρεσία ΓΕΜΗ (KEEE) διαθέτει για τους developers διεπαφή πρόσβασης σε δεδομένα ΓΕΜΗ. Διατίθενται δημόσια προσβάσιμα δεδομένα μερίδας ΓΕΜΗ, όπως γενικά διατίθενται και στην Δημοσιότητα ΓΕΜΗ. Σκοπός της υπηρεσίας είναι η διάθεση ανοικτών δεδομένων (open data) από το ΓΕΜΗ με χρήση ενός καλά τεκμηριωμένου API ώστε οποιοσδήποτε ενδιαφερόμενος να μπορεί να αναπτύξει τρίτες υπηρεσίες με χρήση αυτών των δεδομένων."

The Central GEMI Service (KEEE) provides developers with an interface for accessing GEMI data. The publicly accessible data of a GEMI record is made available, as it generally is in Δημοσιότητα ΓΕΜΗ. The purpose of the service is to provide open data from GEMI through a well-documented API, so that any interested party can develop third-party services using this data.

A register stating, in its own words, that it wants third parties to build services on its data is worth noting plainly. It also sets the scope precisely: the API carries the same publicly accessible data as the free search, not a different or larger set.

Where a Greece lookup stops

The General Secretariat of Commerce describes the division of the two portals: "Στον σύνδεσμο https://publicity.businessportal.gr/ διατίθενται δημόσια και δωρεάν δημοσιευτέα στοιχεία και πληροφορίες επιχειρήσεων που είναι εγγεγραμμένες στο Γ.Ε.ΜΗ." — publishable data and information on businesses registered in Γ.Ε.ΜΗ. are made available publicly and free of charge. Separately, services.businessportal.gr handles certificate requests, application tracking, and authenticity checks on GEMI certificates and announcements.

So the routing rule is: publicity for reading, services for documents and for verifying that a document is genuine.

This page does not describe what ΚΑΚ stands for or how it is issued, and it does not describe what the financial-data field contains. Neither was sourced. GREECE_REPORT.md names both.

Where the question is a population rather than a company, a firmographic directory covers the same registered businesses 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 Greece

Assuming every Greek record carries a website. gov.gr lists website and e-shop among the details in the record; it does not state how completely the field is populated.

Treating the financial-data field as a known quantity. Its existence is stated; its contents and the entity types it covers are not.

Searching one alphabet only. The register searches names and distinctive titles regardless of spelling and of whether Latin characters are used — a search that does not exploit that is doing work the register already does.

Reading an empty result as absence. Between transliteration variation and the deleted-business population, an empty result in Greece has several explanations before absence.

Flat-matching ΚΑΔ codes. Activity search is organised hierarchically across several levels, so a flat code match may miss the level the data actually sits at.

Expecting the API to hold more than the search. The Central GEMI Service states the API carries the publicly accessible data of a GEMI record, as it is generally available in Δημοσιότητα ΓΕΜΗ.

Requesting authenticity checks from the wrong portal. Certificates, application tracking and authenticity checks sit on services.businessportal.gr, not on the publicity search.

A repeatable Greece company lookup workflow

1. Search free text in whichever script you have, and let the register absorb the spelling variation.
2. Filter to both active and deleted businesses when history matters.
3. Read the website and e-shop fields, but verify coverage before relying on them across a population.
4. Record the EUID alongside the Γ.Ε.ΜΗ. number for any cross-border work.
5. Query ΚΑΔ at the hierarchy level your question is actually about.
6. Go to services.businessportal.gr for certificates and to check a document's authenticity.

Frequently asked questions

Does the Greek register hold a company's website?

gov.gr lists details of the website and e-shop among what the search returns. How completely that field is populated across companies is not something this page states.

Can I search Greek companies in Latin characters?

Yes. The free search covers company names and distinctive titles regardless of spelling and of whether Latin characters are used, and the name in Latin characters is itself a stored field.

Can I find companies that no longer exist?

Yes. Both active and deleted commercial businesses required to register in Γ.Ε.ΜΗ. can be searched, with filters for legal form, status and activity.

What is the EUID and why is it on the record?

It is the European unique identifier, and gov.gr lists it among the fields the search returns. Through the European e-Justice Portal, company information can be searched across the interconnected EU national registers, GEMI included, by company name and commercial register number.

Is there an official API?

Yes. The Central GEMI Service provides a developer interface whose stated purpose is to provide open data from GEMI through a well-documented API so that any interested party can develop third-party services using it.

Does the API hold more than the free search?

No. It makes available the publicly accessible data of a GEMI record, as generally available in Δημοσιότητα ΓΕΜΗ.

Where do I get a certificate or check one is genuine?

At services.businessportal.gr, which handles certificate requests, application tracking, and authenticity checks on GEMI certificates and announcements.

What financial data does the record hold?

gov.gr lists financial data among the record's contents. What it contains and for which entity types was not established from the sources read for this guide.

Source Register

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

This page states that the record includes financial data as listed by gov.gr and deliberately says nothing about what that field holds — its existence is sourced, its contents are not. It likewise does not describe what ΚΑΚ stands for or its issuance rules. GREECE_REPORT.md records both, with what would confirm them.

The readings that are InfobelPRO's rather than the register's: that the website and e-shop fields amount to a legal-entity-to-web-presence join most data work has to construct from outside; that assuming population coverage from the existence of a field is the inference that produces confident wrong data; that transliteration-tolerant search removes a class of silent false negatives, where an empty result looks like absence; and that publishing the EUID on a free record makes the cross-border identifier something you can read rather than something you have to derive. Those are ours. The comparison with Poland is a comparison of where two registers keep the past reachable, offered without ranking.
