The province is currently represented in the lower house of the Congress of the Philippines through its lone congressional district.
The province has never been redistricted, and its boundaries have remained constant since then.
It is among the original representative districts from 1907 which has never changed in territorial coverage.
However, in 1935, all senatorial districts were abolished when a unicameral National Assembly was installed under a new constitution following the passage of the Tydings–McDuffie Act, which established the Commonwealth of the Philippines.
Antique has been represented in the lower house of various Philippine national legislatures since 1898, through its at-large congressional district.
