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)

Analysis of SnappCode

Overall verdict

  • I don't have verified information about SnappCode (snappcode.eu) in my training data, so I can't confirm its quality, features, pricing, or reputation. It may be a newer, niche, or low-visibility product that hasn't been widely reviewed or documented in sources available to me. I'd recommend checking independent review sites, user forums, Trustpilot, or the Wayback Machine for historical site data, and looking for verifiable user testimonials before making a decision.

Why this product is good

  • Insufficient verified data available to confirm claims about features or performance
  • No independent reviews or reputable third-party coverage found in available knowledge
  • Cannot verify company legitimacy, security practices, or customer support quality
  • Domain-specific services can vary widely in quality, so direct research is advised

Recommended for

  • Users willing to do their own due diligence by checking recent reviews and user feedback
  • Those who can test the service directly (e.g., via free trial) before committing
  • People comfortable verifying company legitimacy through domain registration, business registries, or contact verification
  • Not recommended as a blind choice without further independent verification
