The province, which was then known as Sandjak (county) of Alexandretta, was under French control as a part of the French Mandate of Syria between 1920 and 1938. In 1938, it appeared on the maps as the independent State of Hatay. Following a plebiscite a year later, it joined Turkey as the Hatay Province in 1939.
The main highway connecting the province to the rest of Turkey to the north is the motorway O-53 (toll-road). There are also secondary highways as well, some of which eventually reaches one of many border posts located on the Turkish-Syrian border.
The telephone code of the province is 326, which should be prefixed with 0 when calling from elsewhere in Turkey, or with +90 when calling from out of Turkey.
