The province and the city are currently represented in the lower house of the Congress of the Philippines through their first, second, third, fourth, fifth, and sixth congressional districts.
In the disruption caused by the Second World War, two delegates represented the province in the National Assembly of the Japanese-sponsored Second Philippine Republic: one was the provincial governor (an ex officio member), while the other was elected through a provincial assembly of KALIBAPI members during the Japanese occupation of the Philippines.
Upon the restoration of the Philippine Commonwealth in 1945, the province retained its five pre-war representative districts.
It was part of the representation of Region I from 1978 to 1984, and from 1984 to 1986 it elected 6 assemblymen at-large.
Pangasinan was reapportioned into six congressional districts under the new Constitution[1] which was proclaimed on February 11, 1987, and elected members to the restored House of Representatives starting that same year.
