ZIP Code API Reviews and Details
This page is designed to help you find out whether ZIP Code API is good and if it is the right choice for you.
API for US ZIP, ZIP+4, and Canadian postal code data. One unified endpoint set covers North America — no separate APIs by country or data type.
What it does
- Address validation and standardization — production-grade parser with ZIP+4 append, refreshed monthly
- Radius search — centroid haversine and true spatial polygon intersection. Returns ZIPs/FSAs within range, with per-result
pct_insideoverlap percentage for spatial queries - Unified lookup endpoint — accepts US ZIP, ZIP+4, Canadian FSA, full Canadian postal codes, or latitude/longitude inputs
- Autocomplete/typeahead — cities, counties, metros, states, FSAs, ZIPs
- Point-to-point distance — between any two postal points
- Census ACS demographics — 2011–2024, 542 fields per ZIP across income, education, housing, social, and economic profiles
- Boundary lookups — Census tracts, congressional districts, state legislative areas, school districts — with computed intersection percentages per ZIP
What makes it different
- Licensed commercial data — not commodity or scraped sources
- Canadian postal coverage — most peers in this space are US-only
- True spatial radius — not just centroid haversine
- 14 years of historical ACS depth via API — unusual outside of raw Census downloads
- One endpoint for all of North America — no country-detection or input-routing logic to maintain on the client side
