  Pasay covers a total land area of 18.64 square kilometers (7.20 sq mi), making it the third smallest political subdivision in the National Capital Region and fourth in the whole country. It borders the capital city of Manila to the north, Parañaque to the south, Makati to the northeast, Taguig to the east, and Manila Bay to the west. The city can be divided into three distinct areas: the city's urban area with an area of 5.505 square kilometers (2.125 sq mi); the Civil Aeronautics Administration (CAA) complex, which includes Ninoy Aquino International Airport (NAIA) and the Villamor Airbase, with an area of 9.5 square kilometers (3.7 sq mi); and the existing reclaimed land from Manila Bay with an area of 4.00 square kilometers (1.54 sq mi). The under-construction Pasay Harbor City and new SM Prime land reclamation projects are expected to add 6.25 square kilometers (2.41 sq mi) to the city's total land area.
  
  Pasay is composed of two districts, subdivided into 20 zones, with a total of 201 barangays. The barangays do not have names but are only designated with sequential numbers. The largest zone, with an area of 5.10 square kilometers (1.97 sq mi), is Zone 19, which covers barangays 178 and 191. The smallest zone with an area of 10 hectares (25 acres) is Zone 1, covering Barangays 1 to 3 and 14 to 17.
