The passport of Kosovo (; / ) is a travel document that is issued to the citizens of Kosovo. The document facilitates international travel as well as serving as proof of citizenship. The issuance of passports is the prerogative of the Ministry of Internal Affairs, with the exception of diplomatic passports which are issued by the Ministry of Foreign Affairs. Kosovar passports comply with all the recommended standards set for machine-readable passports by the International Civil Aviation Organization (ICAO) (such as size, technology, security, layout, etc.), but the country/citizenship code RKS is not within ISO 3166 and thus not ICAO-endorsed. The passport design was disclosed on 14 March 2008. The first passports were issued on 30 July 2008 and as of 20 May 2009, 300,000 passports have been issued to the citizens of Kosovo. The new design of the passport is a burgundy colour, with the coat of arms of the Republic of Kosovo in the middle of the cover page. The word "Passport" is written on the cover of the passport in Albanian, Serbian and English. All relevant identity information about the bearer is printed in these languages as well. For citizens that are 18 years old or older, the passport is valid for 10 years from the date of issue. Before the introduction of the new national passports, travel documents were issued by the United Nations administration with a maximum validity of 2 years. Those travel documents ceased being issued in 2008, with the remaining documents valid until 2010. Biometric passport The Kosovo biometric passport has been issued since 31 October 2011. In May 2011, the Ministry of Interior announced that biometric passports would be issued in the summer of 2011 after the winning firm is chosen and awarded the production of the passports.
