Turkey's national postal and telegraph authority is PTT, which stands for Posta ve Telgraf Teşkilatı. Previously known as Posta Telgraf Telefon, the organization underwent a name change after privatizing the telecommunications business but kept its well-known abbreviation. The headquarters are located in Ankara, recognized worldwide as Turkish Post.

The Ministry of Posts of the Ottoman Empire was established in 1840 during the reign of Abdul Mejid I. The telegraph service was introduced in 1855, followed by the launch of the first telephone service in 1909. The ministry's name was later changed to Posta Telgraf Telefon (PTT) for 86 years. After establishing the Republic of Turkey in 1923, the church became the general administration of the new republic. In 1995, telephone and telecommunications services were transferred to the newly formed Türk Telekom. As a result, the organization was renamed "Organization of Post and Telegraph" while keeping its familiar abbreviation PTT.
