The Croatian VAT identification number is known by several names: VAT ID, OIB, Croatian VAT. Also referred to as VAT number HR or Croatia VAT ID. All terms refer to the same number registered in the EU VIES system.
What is the difference between VAT ID, tax number (Steuernummer) and MwSt number?

The tax number (Steuernummer) is a purely national identifier issued by the local tax office and has no relevance for cross-border trade. "Umsatzsteuer-Nummer" is often used synonymously but technically means the VAT ID. The terms "MwSt-Nummer" and "Mehrwertsteuer-Nummer" refer to the same number — only the label differs.
