Philadelphia Zip Code Map


Philadelphia County, Pennsylvania, utilizes ZIP Code Tabulation Areas Zip Codes (ZCTAs - Census Zip Codes) for organizing postal routes, demographic analysis, and census data. A ZCTA is a generalized area created by the U.S. Census Bureau to approximate ZIP code regions for statistical purposes, mostly matching up with postal ZIP codes but refined for population and land area estimates. In Philadelphia County, ZIP codes range from 19019 to 19154, covering diverse urban neighborhoods, suburbs, and commercial zones. This range includes both high-density residential areas and less-populated industrial zones.

Philadelphia County is home to nearly 50 ZIP codes, which span multiple neighborhoods but collectively cover only the city of Philadelphia, as the county and city boundaries are coterminous. This organizational structure supports over 20 post offices throughout the county, ensuring access to postal services across neighborhoods. ZIP code 19120 is one of the most populated, encompassing parts of the Olney and Feltonville neighborhoods, while some ZIP codes, like 19106 in the historic Old City area, are less populated due to concentrated commercial use.

Philadelphia’s ZCTAs serve a critical role in census reporting, supporting city planning, economic development, and infrastructure projects. The arrangement of ZIP codes within the county helps reflect demographic shifts, providing granular insights into income levels, household sizes, and educational attainment across the city. This information is invaluable for public policy, urban planning, and business analytics, highlighting Philadelphia’s unique blend of historic districts and growing residential communities. Additionally, the presence of numerous PO boxes offers residents and businesses flexible mailing options.
