Analysis of PostalDataPI

Overall verdict

  • I don't have verified, up-to-date information specifically about PostalDataPI (postaldatapi.com), including details on its accuracy, pricing, uptime, or customer reviews. I can't confirm whether it's a good product without more direct data or firsthand testing, so I'd recommend evaluating it yourself using the criteria below before committing.

Why this product is good

  • Unable to verify specific claims about data accuracy, coverage, or update frequency for this service
  • No confirmed information on pricing tiers, rate limits, or API reliability (SLA/uptime)
  • No verified user reviews, testimonials, or third-party comparisons available
  • Company background, support quality, and documentation quality are unconfirmed
  • If considering this service, check for: free trial/sandbox access, transparent pricing, data source citations, response time benchmarks, and independent reviews on sites like G2 or Trustpilot

Recommended for

  • Not able to make a specific recommendation without verified data
  • Best approach: developers needing postal/address validation APIs should compare this against established alternatives (e.g., SmartyStreets, Lob, Google Maps Geocoding API, USPS Web Tools) based on documented accuracy and pricing
  • Suitable evaluation candidates: teams willing to test the API directly with sample data before integrating into production systems

  • GIS or map (to import CSV addresses) not GPS coords & label EACH on a map?
    Try geocod.io, it gives you a few hundred free geocodes per day. Source: over 3 years ago
  • Looking for US medical provider -> doctor's office / practice location(s) -> hospital network -> insurance dataset
    Lat/lon you'll probably have to pay for. We used geocod.io to get lat/lon for all practices and providers. It cost about $6k for all 7M records, I think. Source: almost 4 years ago
  • Anyone interested in a geo-encoded address data service (OSM and Google Maps alternative)?
    If I correctly get it, then geocod.io only does US and Canada? Source: almost 4 years ago
  • Home value "isotherm" style map.
    Sounds like a cool project (and insane market - I'd hate to have to buy somewhere like that) and thanks for the geocod.io link. I'll check em out. If you'd like to send me a small sample dataset (maybe just paste some tsv into here), I'd love to play with it in my free time and see what I can make. Source: over 4 years ago
