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_inside overlap 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

Pricing

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

Data8 UK features and specs

  • Comprehensive Data Validation Services
    Data8 offers a wide range of real-time data validation services including email verification, phone number validation, address lookup, and bank account validation, making it a one-stop solution for businesses needing to ensure data quality at the point of capture.
  • UK-Focused Expertise
    Data8 specializes in UK data, providing highly accurate and up-to-date validation for UK addresses, postcodes, and phone numbers. Their deep focus on the UK market means businesses operating primarily in the UK get tailored and reliable results.
  • Easy Integration Options
    Data8 provides APIs, plugins for popular CRM systems like Microsoft Dynamics 365, and web form integrations, making it relatively straightforward for developers and businesses to incorporate their services into existing workflows and systems.
  • Pay-As-You-Go Pricing
    Data8 offers flexible credit-based, pay-as-you-go pricing models, which can be cost-effective for smaller businesses or those with variable data validation needs, as you only pay for the lookups you actually use.
  • Real-Time Validation
    Their services validate data in real time at the point of entry, which helps prevent bad data from entering systems in the first place, reducing downstream costs associated with cleaning and correcting inaccurate records.

Possible disadvantages of Data8 UK

  • Limited Global Coverage
    While Data8 excels in UK data validation, its international coverage may not be as comprehensive or accurate as competitors that specialize in global data services. Businesses with significant international operations may need supplementary providers.
  • Credit Expiry Concerns
    Purchased credits may have expiry dates, meaning businesses that don't use their allocation within the specified timeframe could lose their investment, which can be frustrating for companies with irregular or seasonal validation needs.
  • Learning Curve for Advanced Features
    While basic integrations are straightforward, setting up more advanced configurations, custom API implementations, or complex CRM integrations may require technical expertise and can involve a learning curve for less technical users.
  • Costs Can Scale Quickly
    For high-volume users, the pay-per-lookup pricing model can become expensive compared to competitors offering flat-rate or enterprise-level pricing tiers, making it less cost-effective for large-scale data cleansing projects.
  • Limited Brand Recognition
    Compared to larger data quality providers like Experian or Loqate, Data8 has less brand recognition, which can make it harder for decision-makers to justify choosing them, and their support ecosystem and community resources may be smaller as a result.

ZIP Code API features and specs

  • Comprehensive ZIP Code Data
    The ZIP Code API from zip-codes.com provides extensive data including ZIP code details, city information, state data, and geographic coordinates, making it a thorough resource for location-based lookups.
  • Multiple Lookup Options
    The API supports various types of lookups including ZIP code to city/state, city/state to ZIP code, distance calculations between ZIP codes, and radius searches, offering flexible querying capabilities.
  • Easy Integration
    The API uses standard REST-based HTTP requests and returns data in commonly used formats like JSON and XML, making it straightforward to integrate into most applications and programming languages.
  • Distance and Radius Calculations
    The API includes built-in functionality for calculating distances between ZIP codes and finding ZIP codes within a specified radius, which is valuable for store locators, shipping estimates, and proximity-based features.
  • Well-Documented Endpoints
    The API provides clear documentation for its various endpoints and parameters, helping developers understand available features and implement them correctly without extensive trial and error.
