IPGeolocation.io is a complete IP intelligence platform that helps businesses turn any IPv4 or IPv6 address into accurate location, network, security, and user context data. Its IP Location API provides real-time country, city, state or province, ZIP/postal code, latitude and longitude, timezone, current local time, currency, language, country calling code, ISP, company, network, and domain-related details in developer-friendly JSON and XML formats over HTTPS.

Beyond basic IP geolocation, IPGeolocation.io offers a growing suite of APIs for fraud prevention, cybersecurity, personalization, analytics, compliance, and network intelligence. The platform includes an ASN API for autonomous system, route, organization, peer, upstream, and downstream data; an IP Security API for VPN, proxy, Tor, relay, bot, spam, cloud provider, anonymous traffic, known attacker, and threat score detection; and an Abuse Contact API to retrieve abuse reporting contacts for suspicious IP ranges.

IPGeolocation.io also supports live VPN and proxy detection, helping businesses identify anonymized traffic during signups, logins, payments, live chats, referral programs, and other high-risk user actions. Additional APIs include Timezone API, Astronomy API, User-Agent API, bulk IP lookup, hostname and domain lookup, and downloadable IP intelligence databases for teams that need high-volume enrichment or offline processing.

With free and paid plans, IPGeolocation.io is suitable for developers, SaaS platforms, cybersecurity teams, adtech companies, ecommerce businesses, fintech apps, and enterprises that need reliable IP geolocation, threat intelligence, abuse detection, ASN data, and real-time decisioning from a single platform.

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
