EORI Number for Croatia

What is the EORI number in Croatia?

Every business that clears goods through Croatia's border needs an EORI (Economic Operators Registration and Identification) number — the operator ID that Croatian Customs Administration issues and that customs systems check on every declaration. Structurally it is the HR prefix plus a national identifier (a correctly formed example is HR12345678901), and because the EU EORI system is shared, one Croatia-issued number covers declarations anywhere in the EU. Without it, an import or export declaration in your name simply cannot be processed.

Who needs an HR EORI number?

If your business is established in Croatia and you import, export, or are named as importer/exporter of record on a customs declaration, you need an EORI before the first shipment moves. This covers limited companies, sole traders and partnerships alike — whether you're bringing in stock from outside the EU, shipping to customers abroad, or fulfilling orders through a marketplace that crosses a customs border. Using a forwarder or courier to file the paperwork does not change this — the declaration still records your own EORI.

The EU EORI system runs on a one-registration principle: you apply in the single member state where your business is established, and for a Croatia-established business that means going through Croatian Customs Administration. Once issued, your HR number is recognised across all 27 EU member states — no need to re-register separately for each country you sell into or buy from. Non-EU operators whose first EU declaration happens to be filed in Croatia can also obtain their EORI there.

One thing an EU EORI does not cover is Great Britain. A Croatia business that also imports into the UK under its own name still needs a distinct GB EORI issued by HMRC — details are in our UK EORI guide.

How to apply for an EORI number in Croatia

1. Check whether you already have one. Authorities often assign EORI numbers automatically when a business first interacts with customs. Search old customs correspondence or ask your forwarder, and try our EORI checker with your likely number — the format is usually HR plus your national tax or business identifier.
2. Gather your business details. You will typically need your company registration number, VAT or tax ID, legal form, registered address and contact details of an authorised person.
3. Apply with Croatian Customs Administration. Applications go through the official portal — depends on review and documentation; allow time before first shipment. Registration is free of charge; no official authority charges for issuing an EORI.
4. Validate before your first shipment. Once issued, confirm the number is active with our free checker so your first declaration is not rejected over a typo or a not-yet-propagated registration.

Checking and using your Croatia EORI number

EU EORI validation (EU EOS) + Croatian customs confirmation. HR registrations live in the EU's shared EOS database, so it isn't only you who can check the number — trading partners elsewhere in the EU routinely verify a new supplier's or customer's EORI before the first shipment goes out.

Once active, your EORI appears on every customs document tied to your business: import and export declarations, transit paperwork, safety and security filings, and any customs authorisations you hold. Couriers such as DHL, FedEx and UPS will ask for it before they can clear commercial goods in your name. Keep the exact string handy in your shipping profiles — a single mistyped character is enough to stop a consignment at the border. You can compare your number against the national pattern in our EORI format hub, which covers every country's structure with valid examples.
