Tips
ZIP code search: You can type a 5-digit ZIP code directly into the search bar and press Go to jump to it and draw its boundary.
Large cities: Cities like Minneapolis, Denver, or Chicago contain dozens of ZIP codes. Searching a city name will show the ZIP code for that city's center point only. To explore other ZIP codes within a city, click different spots on the map — each click draws the boundary for that specific location's ZIP code.
Boundaries shown: The boundary drawn is the ZIP Code Tabulation Area (ZCTA) as defined by the US Census Bureau — it represents a geographic area, not a city or neighborhood boundary. It closely follows but may not exactly match USPS mail delivery boundaries.
Coverage: US only. Some rural routes and PO Box-only ZIP codes may not have a mappable boundary.
Disclaimer
ZIP code boundaries shown are ZIP Code Tabulation Areas (ZCTAs) as defined by the US Census Bureau and may differ from official USPS delivery boundaries. For authoritative delivery boundary information, consult the USPS directly. GeoWorkbench assumes no liability for decisions made based on this tool.
