API for US ZIP, ZIP+4, and Canadian postal code data. One unified endpoint set covers North America โ€” no separate APIs by country or data type.

What it does

  • Address validation and standardization โ€” production-grade parser with ZIP+4 append, refreshed monthly
  • Radius search โ€” centroid haversine and true spatial polygon intersection. Returns ZIPs/FSAs within range, with per-result pct_inside overlap percentage for spatial queries
  • Unified lookup endpoint โ€” accepts US ZIP, ZIP+4, Canadian FSA, full Canadian postal codes, or latitude/longitude inputs
  • Autocomplete/typeahead โ€” cities, counties, metros, states, FSAs, ZIPs
  • Point-to-point distance โ€” between any two postal points
  • Census ACS demographics โ€” 2011โ€“2024, 542 fields per ZIP across income, education, housing, social, and economic profiles
  • Boundary lookups โ€” Census tracts, congressional districts, state legislative areas, school districts โ€” with computed intersection percentages per ZIP

What makes it different

  • Licensed commercial data โ€” not commodity or scraped sources
  • Canadian postal coverage โ€” most peers in this space are US-only
  • True spatial radius โ€” not just centroid haversine
  • 14 years of historical ACS depth via API โ€” unusual outside of raw Census downloads
  • One endpoint for all of North America โ€” no country-detection or input-routing logic to maintain on the client side

Pricing

  • Free โ€” 2,500 lookups/day, no credit card required, no expiry
  • Developer โ€” $49/mo, 100K credits, 300/min
  • Professional โ€” $149/mo, 350K credits, 300/min
  • Business โ€” $499/mo, 1.5M credits, 600/min
  • Credit packs โ€” one-time, from 25K ($19) up to 2M ($799)

Possible disadvantages of Unleashed Software

  • Cost
    While Unleashed Software offers many advanced features, it can be relatively expensive, particularly for small businesses or startups with limited budgets. Subscription plans might not be affordable for everyone.
  • Complexity for Simple Operations
    For businesses with less complex inventory needs, Unleashed's comprehensive feature set could be overwhelming and unnecessarily complex. Simpler operations might find the extensive options and settings more cumbersome than beneficial.
  • Limited Offline Capabilities
    Unleashed Software is cloud-based, meaning it requires an internet connection to access. This can be a limitation for businesses operating in areas with unreliable internet access or for users who need to work offline.
  • Setup and Implementation Time
    The initial setup and implementation can be time-consuming and may require a significant amount of data entry and customization. This process might necessitate dedicated time and resources, which could be a drawback for some businesses.
  • Customer Support
    While Unleashed offers customer support, some users have reported that the response times can be slow, and the quality of support can sometimes be inconsistent. This might pose a challenge for businesses needing immediate assistance.
