Caoayan stood before as one of the boundary marks between the Provinces of La Union and Benguet due to the river that flow between these two Provinces. Stories have been told that when the late Don Polon Bentrez visited the place to inspect the boundary, there were few inhabitants with about 8-10 bamboo houses. Along the river bank were huge and robust hard bamboos. As Don Polon stood at the upper most part of the area (just below the existing national highway), he was amazed with the tall bamboos swaying and dancing with the wind. While he was enjoying the beautiful green scenery, one of the old folks told him that “Dagita ket Kawayan”. It was that time Don Polon called the place “Kawayan” and eventually carried on by the inhabitants.
The barrio of Caoayan was then first headed by the late Timoteo Quezada as “Teniente del Barrio” during the later days of the Commonwealth Period (late 1930s) and was succeeded by the late Carlos Ordinario until the Japanese Occupation (mid – 1940s).
Bounded on the south by Old Poblacion; north by Lower Tumapoc; east by Dalacdac and west by Ribsuan (Naguilian, La Union), Barangay Caoayan is guarded by the Dalacdac-Caoayan-Ribsuan River (popularly known as Ribsuan River) where rich aquatic resources could be found.
It has two sitios namely: Centro, being in the center of the community and at the western part, Caoayan Extension. One could enjoy the temperately hot climate of the place.
It has one barangay road traversing from Old Poblacion to the center of the barangay with an approximate length of 2.0 kms. Residents are mostly Ilocanos.
Most of the residents are engaged in farming; taking advantage of the ready and available irrigation from the Soybuan – Ribsuan River. At present, the farmers plant and harvest palay trice a year.
The Barangay has a total population of 471 (in 2015) occupying the 13.2447 hectare-barangay.
