During the excavation, the Tell Fekheriye bilingual inscription (in the Assyrian dialect of Akkadian and Aramaic) was discovered at the site, which provides the source of information about Hadad-yith'i.

[2][8][9] However this identification received a new support by Stefano de Martino due to recent archaeological excavations by a German team led by Mirko Novák and Dominik Bonatz.

[11] The Neo-Assyrian city Sikan at nearby Ra's al-'Ayn was identified by Dietrich Opitz as the capital of Mitanni, Washukanni.

The etymology is challenged by Edward Lipiński, who points out that Sikan is a Semitic name (meaning stele) already attested for the site circa 2000 BC.

In 1929, during his excavations at Tell Halaf, he dispatched Felix Langenegger and Hans Lehmann to the site to do a field survey, resulting in the production of a contour map.

[17] In 1940, a team from the Oriental Institute of Chicago and the Boston Museum of Fine Arts, led by Calvin W. McEwan, and which included Harold D. Hill, worked for a short period there, conducted several soundings, developed a contour map of the site, and collected various pottery and epigraphic objects.

[21] After a survey in 2005, a team from the Free University of Berlin and SAHI - Slovak archeological and historical institute and the Syrian Directorate-General of Antiquities and Museums resumed work at Tell Fakhariyah for a month in 2006.
