To obtain a PIN/OIB in the Republic of Croatia, a foreign national must go to a tax administration office and fill out the Request for assigning a personal identification number and enclose a copy of his/her passport or a European identity card if he/she is a citizen of the European Union. In case of a foreign legal entity, it is necessary to submit the Articles of Association (decision or excerpt from the competent register along with the Request for assigning PIN/OIB) in the tax administration office. All the documents must be in the Croatian language or translated into the Croatian language by a certified court interpreter.
