OIB, also known as Osnovni identifikacijski broj or Personal Identification Number (PIN) in English, is a unique numerical identification code assigned to each citizen of Croatia. OIB serves as a primary means of identification and demographic information for individuals living in Croatia.
The OIB is a 11-digit number consisting of numerical digits from 0 to 9. The first nine digits represent the individual's birth date including day, month, and year, while the final two digits are control digits generated using a specified algorithm. This control number provides a mechanism to verify the accuracy and integrity of the OIB.
The OIB is widely used and required by various government institutions and agencies, including tax authorities, healthcare providers, financial institutions, and educational establishments for official transactions and record-keeping purposes. It facilitates efficient communication and data exchange between these entities while ensuring accuracy in personal data.
The OIB helps in streamlining administrative processes, simplifying identification procedures, and reducing duplication of records. It also enhances transparency, accountability, and accuracy in public administration. The implementation of OIB has proven beneficial in various sectors, such as taxation, social security, healthcare, and statistical analysis, as it assists in identifying and monitoring individuals' activities.
Overall, the OIB plays a crucial role in the Croatian administrative system by providing a unique identifier for each citizen, thereby facilitating efficient public services and maintaining accurate demographic information.
