Slovenian car number plates are vehicle registration plates found on Slovenian cars. The code for Slovenia itself is SLO.^[1] The registration plates are made of metal. On the left there is a blue bar as in other EU countries (in use since 2004) along with tamper-proof text up to 2008; the text is in black letters on a white background in Helvetica typeface. In 2008 the plates reverted to a green border used before 2004 and the old font but retaining the EU border at the left. Two plates must be present on each car - one at the front and one at the rear. In the case of motorcycles, only one plate is needed on the back of the vehicle. These plates can have different sizes, being the regional code in the first line, at the top.^[2]

On regular issue license plates, the first 2 letters before the shield sticker denote the region where the car was initially registered. Further division is made by the coat of arms of the corresponding city, placed after the regional area letters to denote subdivisions.^[3]
