They are spoken in an area stretching from the southern shore of Lingayen Gulf to the highlands of Quirino province.

The comparison table (taken from Himes (1998) and Zorc (1979)) illustrates the correspondences between the Southern Cordilleran languages, including inherited vocabulary as well as Southern Cordilleran innovations.
