If you run a business in Greece, your website is no longer just marketing — it's a legal document. Law 4919/2022 (article 22), in force since October 2022, requires every business registered in the General Commercial Registry (ΓΕΜΗ) to display specific company details in a prominent place on its website and e-shop. And since 1 January 2026, a stricter fines framework makes non-compliance genuinely expensive.
What exactly must appear on your website
Article 22 of N. 4919/2022 requires the following, in a prominent place (typically the footer, visible on every page):
- Your company name (επωνυμία) as registered in GEMI
- Your legal form (e.g. sole proprietorship, O.E., E.E., IKE, EPE, A.E.)
- The registered seat (έδρα) of the business
- Your GEMI number (αριθμός ΓΕΜΗ) — look it up on the GEMI business portal
- If the company is in liquidation, that fact must be stated too
Who does this apply to?
Everyone registered in GEMI — which in practice means virtually every business in Greece: sole proprietorships (ατομικές), partnerships (Ο.Ε./Ε.Ε.), IKE, EPE and A.E. The same details must also appear on your letters, order documents and outgoing commercial paperwork. E-shops have additional consumer-law disclosures on top (VAT number, contact details, complaint handling).
What changed in 2026: real fines
The GEMI penalty framework that entered into force on 1 January 2026 gives registry authorities broader inspection powers and higher fines for missing registrations and disclosures — reaching thousands of euros depending on legal form, and up to €100,000 for listed companies. In other words: the rule existed since 2022, but 2026 is the year it grew teeth.
Don't forget GDPR and cookies
GEMI details are only half of website compliance. If your site has a contact form, you're processing personal data and need a privacy policy. If it runs analytics (Google Analytics, Meta Pixel), Greek law 4727/2020 and the Hellenic Data Protection Authority require opt-in cookie consent — the banner must actually block tracking until the visitor accepts, not just inform.
