Location and area
The Northern Borders Region lies in the far north of Saudi Arabia. Iraq and Jordan border it to the north, the Eastern Province to the south, the al-Qassim and Hail regions to the southwest and the al-Jouf Region to the west. Covering about 104,000 km², or 5.3% of the Kingdom, it ranks eighth by area among the thirteen regions.
Its position between the Arabian Peninsula and the Levant made it a historic transit point on pilgrimage and trade routes, and it still links the Gulf states with Jordan, Syria and Lebanon. The Jdeidet Arar land port is the main gateway for pilgrims from Iraq and a trade corridor between the two countries.
Population
The region had 373,577 residents in the 2022 Saudi census, the smallest population of any region, with an annual growth rate of 2.17%.
Arar Governorate is home to 202,719 people, or 54.3% of the region's population, the largest share; Rafha follows, with about a quarter of the region's residents.
Emirate and governorates
The region was constituted administratively in 1992. Its capital and Emirate seat is Arar, where the Emirate stands on King Abdulaziz Road, about 30 km by car from Arar Airport. Prince Faisal bin Khalid bin Sultan bin Abdulaziz has been governor since 2017 (1438 AH), and Prince Mohammed bin Abdullah bin Abdulaziz Al Saud deputy governor since 12 February 2026 (24 Sha'ban 1447 AH).
Besides Arar, the region has three governorates, Rafha in Category A and Turaif and al-Uwayqilah in Category B, and 28 administrative centres. Rafha is the largest governorate by area, followed by Arar; it lies 290 km from Arar and has seventeen administrative centres of its own.
Climate and environment
The climate is continental, with extreme summer heat and cold winters; temperatures fall below zero in January and February, snow falls on some heights, and most rain comes in spring and winter.
The region has four nature reserves: Mu'aylah, al-Uwaysi, al-Gharabah and part of the Harrat al-Harrah reserve. It is a natural habitat for birds and livestock, with grazing for camels and sheep, and the peregrine falcon frequents it, making it a national destination for falconry. Three of the Kingdom's largest valleys, Arar, Badanah and al-Uwaysi, cross Arar Governorate, known for its juniper trees and fertile grazing land; dolomite and limestone are quarried from the valley banks.
From Tapline to modern towns
The region began to change more than seventy years ago, when it became a station on the Tapline, the pipeline that exported Saudi oil, with five pumping stations along its route. The line ran from Hafar al-Batin in the east to Sidon in Lebanon.
In the 1950s Arar was known as Arar Oil Station, a business area housing pipeline workers, and it grew into the region's administrative capital. One of its earliest buildings is the King Saud Palace, built in 1954 of dressed stone brought from mountains about 40 km to the west, over 1,485 m². Rafha was founded as a modern town in 1950, after the Tapline was extended under King Abdulaziz; it had long been a stop for pilgrim and trade caravans from Iraq, and its old market drew townspeople and Bedouin for more than seventy years.
On the Zubaydah road
Darb Zubaydah, the historic pilgrimage and trade road linking Kufa with Makkah, crosses the region, and Rafha was the first Saudi territory it reached; the region served as a stop for water and grazing. Markers trace the route, one near Zubala village and eight at the al-Naqrah station, and the former stations preserve pools, wells, basins, channels and buildings.
The most important of them is Zubala, about 25 km south of Rafha. It predates the Abbasid era and peaked early in it, a meeting place for trade caravans and pilgrims, named after Zubala bin al-Harith. It holds the remains of a square fortress 35 m a side with round corner towers, the foundations of a rectangular mosque, cisterns on the road including al-Shahuf, al-Shiyahiyat and Umm al-Asafir, and a well cut into solid rock with a 10 by 10 m square mouth, 250 m deep, described as the deepest on the pilgrim road. Excavations have been under way since 2015.
Other stations include the square al-Jumaimah pool east of Rafha, with a 13-step staircase; the neighbouring al-Thulaymah pool, circular, plastered and 32 m across; the al-Qa'a centre, 43 km northeast of Zubala, with two rectangular pools, a palace and a mosque; and al-Dhafeeri, the last Darb Zubaydah station within the Kingdom.
Linah and older traces
South of Rafha lies Linah. Its heritage village was founded for trade in 1933 over 5,000 m² and has 80 mud shops shaded by palm-frond canopies on large columns. Its market was a trading hub on the route between the Arabian Peninsula and Iraq, near the Zubaydah road.
About 200 m from the market stands the King Abdulaziz Palace, built in 1935 in the Najdi style of clay, stone and mud brick over about 4,320 m². A square wall with conical corner towers and a large wooden gate encloses rooms for the King, his entourage and guests around a rectangular courtyard, along with a stable, a mosque and a well. It was King Abdulaziz's only residence in the region and the seat of its Emirate, and was restored in 2009 under a programme for state-owned historic buildings from his reign.
Settlement here is far older. In the centre of Linah are stone circles, wall foundations and tools dated to 7500–6500 BCE, and the Arar valley and the hills to its northeast hold stone structures and tools from around 5500 BCE. At Dawqarah, near Mount Aqran, are the foundations of a square palace 42.5 m a side in dressed volcanic stone, and the valleys of al-Shati, al-Gharabah and Badanah carry Safaitic inscriptions, tribal marks and drawings of animals and people. Linah, Zubala, Luqa and Dawqarah are the region's four historic towns.
Mining and the economy
The region is a centre of mining, the third pillar of the Saudi economy after oil and petrochemicals. It holds the world's third-largest phosphate reserves, which could make it the second-largest producer. The al-Jalamid phosphate mine is in the village of Hazm al-Jalamid.
Wa'ad al-Shamal, the mining industrial city, covers 440 km², holds about 7% of the world's phosphate stock, has investment exceeding SAR 85 billion and is financed by the Public Investment Fund. The 1,550 km North Train links the phosphate mines with the Kingdom's coastal ports.
Education and transport
Northern Border University, the region's only public university, was founded in 2007, absorbing the earlier Teachers' College and the King Abdulaziz University branches in Arar and Rafha. Its headquarters is in Arar, just south of the airport, with branches in Rafha, Turaif and al-Uwayqilah.
Arar Regional Airport, the region's main airport, lies 17 km southeast of the city, and Rafha Domestic Airport, with a capacity of 125,000 passengers, is 3 km south of Rafha. A 682 km road links Rafha with Madinah via Hail.
