In 2018, the Federally Administered Tribal Areas (FATA) merged into:

The Federally Administered Tribal Areas (FATA) were a semi-autonomous tribal region in northwestern Pakistan, governed under a special legal and administrative system. In a significant constitutional reform, FATA was officially merged into the province of Khyber Pakhtunkhwa (KPK) in May 2018 through the 25th Amendment to the Constitution of Pakistan.

• This merger aimed to integrate the region into Pakistan's mainstream political, judicial, and administrative systems, extending provincial laws and governance structures to FATA.
• The options 'Punjab', 'Sindh', and 'Baluchistan' are other provinces of Pakistan, but FATA shared its geographical and cultural proximity primarily with KPK, making it the logical province for integration.
