Croatia
In Croatia, the Personal Identification Number (Croatian: Osobni identifikacijski broj (OIB)), is used for identifying the citizens in many government and civilian systems. The OIB-system was introduced on January 1, 2009 and replaced the old JMBG system, renamed to Master Citizen Number (Croatian: Matični broj građana (MBG)) in 2002, that was used in former Yugoslavia. The OIB consists of eleven random digits and the last number is a control number.
