The location of the battle has not been found.
The Arabic chronicle Nihayat al-arab states that the battle took place in bʾdrjʾan or bʾdjʾn, which Widengren translated as *Jurbadhijan (Golpayegan).
This is however improbable, due to Ardashir I operating around Kashkar before the battle.
According to an unfinished work by Bal'ami, the battle took place at Khosh-Hormoz, which is another name for the notable city of Ram-Hormoz, situated near Arrajan and Ahvaz.
This implies that Ram-Hormoz was perhaps another word for Hormozdgan, and also clarifies why the latter is not mentioned by Islamic geographers whilst the former is reported in detail.
The town of Ram-Hormoz still endures today, and is 65 km east of Ahvaz, "in a wide plain just at the foot of the hills that form the northeastern tail of the Bengestan Mountain of the Zagros chain."
According to Shahbazi, "the plain nearby is admirably suited for a cavalry engagement."

According to al-Tabari, whose work was probably based on Sasanian sources, Ardashir I and Artabanus IV agreed to meet in Hormozdgan at the end of the month of Mihr (April).
Nonetheless, Ardashir I went to the place before due time to occupy an advantageous spot on the plain.
There he dug out a ditch to defend himself and his forces.
He also took over a spring at the place.
Ardashir I's forces numbered 10,000 cavalry, with some of them wearing flexible chain armor akin to that of the Romans.
Artabanus IV led a greater number of soldiers, who, however, were less disposed, due to wearing the inconvenient lamellar armor.
Ardashir I's son and heir, Shapur, as portrayed in the Sasanian rock reliefs, also took part in the battle.
The battle was fought on 28 April 224, with Artabanus IV being defeated and killed, marking the end of the Arsacid era and the start of 427-years of Sasanian rule.
