The Philippine Standard Geographic Code (PSGC) is a systematic classification and coding of geographic areas of the Philippines.

It is based on the four well-established hierarchical levels of geographical-political subdivisions of the country such as the administrative region, the province, the municipality/city and the barangay.

Aside from being an instrument of securing uniformity and comparability of various statistics relating to geographic areas, the PSGC has the following other uses:

• As a guide in national as well as local development planning
• As a comprehensive area frame in the conduct of censuses and sample surveys and market studies
• As a comprehensive list of LGUs in the internal revenue allocation (IRA)
• As basis in the establishment of precincts/voting centers
• Establishment of databases
• Development of geographic information systems
• Updating of maps

The 1996 PSGC revises the first PSGC published by the National Economic Development Authority (NEDA) in 1977. It is based on the masterlist of barangays as of 31 December 1996 established by the Technical Working Group on Geographic Classification (TWG-GC) under the NSCB Technical Committee on Statistical Standards and Classification (TCSSC) composed of members from the following agencies:

• Commission on Elections (COMELEC)
• Department of the Interior and Local Government (DILG)
• National Statistics Office (NSO)
• National Computer Center (NCC)
• National Mapping and Resource Information Administration (NAMRIA)
• Department of Budget and Management (DBM)
• National Statistical Coordination Board (NSCB)

The 1996 PSGC incorporates all changes in the geographical-political subdivision that took place from 977 to 1996 such as changes in names, status (e.g. "sitios" converted into a barangay or a municipality converted into a city, etc.) and number of geographical-political unit from the regional down to the barangay level as a result of new creations, transfer, merger and abolition.

To make the 1996 PSGC more useful, the Department of Finance (DOF) classification of provinces, cities and municipalities by income size and the NSO urban-rural classification of barangays based on the 1970 definition were incorporated in the code book.
