The company was founded in 1959, originally under the name of "The Post, Telephone and Telegraph of Kosovo", and adopted its current name on 12 September 1990. PTK stopped operating only during the Kosovo War. During the conflict, assets of the company were either stolen or destroyed, leading to interruptions of postal and telecommunication services. After the conflict, PTK launched Vala, the largest mobile operator in the country, with the assistance of Monaco Telecom. Vala was the first licensed mobile operator in Kosovo.
