Croatia

Croatia, a European nation, is identified internationally by the ISO codes HR (two-letter) and HRV (three-letter). To call Croatia from abroad, use the +385 country calling code. Its internet presence is anchored by the country-code top-level domain (ccTLD) `.hr`, used for local domain registrations. As a member of the eurozone, Croatia's official currency is the euro (EUR), critical for financial transactions, invoicing, and cross-border business. These identifiers—+385, HR/HRV, .hr, and EUR—are essential for telecommunications, web addressing, and commerce, ensuring accurate routing of calls, validated domain ownership, and standardized economic operations within the region.
