Posta Hizmetleri
The history of postal services in Turkey is fascinating. The Posta Nezareti was established on October 23, 1840, to cater to the postal needs of the Ottoman Empire.
This marked a significant milestone in the development of postal services in the region. The Posta Nezareti played a crucial role in facilitating communication between people and places.
The organization underwent a significant transformation in 1909, when telephone services were added to its portfolio. The name was changed to PTT Nezareti, reflecting the expanded services.
The PTT Nezareti continued to evolve, and on June 18, 1994, it was restructured into three separate entities: the T.C. Posta İşletmesi Genel Müdürlüğü, the Türk Telekomünikasyon Anonim Şirketi, and the PTT İşletmesi Genel Müdürlüğü.
This restructuring had a significant impact on the way postal services were delivered in Turkey.

The company was privatized on 14 November 2005, with a 55% stake being transferred to Oger Telekomünikasyon A.Ş. for $6.55 billion, the largest sale in Turkish history at the time.

This massive sale made headlines, but it was later surpassed by the 2013 Istanbul airport tender.
The privatization process involved transferring cable TV broadcasting and internet services to Türksat, while also handing over maritime communication and navigation services to the Turkish Coast Guard.
In July 2018, Oger Telekom was unable to pay its debts to banks, leading to the banks taking over the company's shares in Turkish Telekom.
The transfer of Turkish Telekom's shares was finalized after receiving approval from the Ministry of Finance and Treasury on August 29, 2018.

Hike Wholesale Tariffs Twice Yearly
Turkish Telekom has a unique business operation where they hike their wholesale tariffs twice yearly.
Their wholesale tariffs are adjusted every January 1st and July 1st, with the new rates taking effect from these dates.
The adjustment is based on the previous year's inflation rate, specifically the Yurt İçi Üretici Fiyat Endeksi (ÜFE), or the Producer Price Index (PPI) in English.

The exact amount of the tariff increase is determined by the ratio of the current year's ÜFE to the previous year's ÜFE.
For instance, if the current year's ÜFE is 10% higher than the previous year's, the wholesale tariffs will increase by 10% as well.
Here's a summary of the wholesale tariff adjustment schedule:
Turkish Telekom will announce the new tariff rates at least one month before the adjustment date.
