Which IP provider actually knows where you are?
Real-world accuracy rankings for IP geolocation, powered by location ground truth. 15 providers tested head-to-head, fully transparent.
Find out which providers get your location right — and help rank them all.
Three steps. Ten seconds. Real data.
A transparent, reproducible methodology for comparing IP geolocation accuracy against ground truth.
Grant Location Access
We request device coordinates to establish the reference point. The ground truth all providers are measured against.
Query Every Provider
Your IP is sent simultaneously to every provider. We capture their city, region, country, and coordinate responses.
Compare Against Truth
Results are compared against ground truth. Accuracy scores and distance errors are calculated for each provider.
IP geolocation has a measurement problem
Most accuracy claims come from the providers themselves, without any evidence or tested under conditions they control. Learn more
How accuracy is measured today
Self-reported metrics. Providers publish their own accuracy numbers, tested against internal datasets with undisclosed methodology.
Stale snapshots. Academic studies test a fixed set of IPs at a single point in time — they don't reflect how accuracy changes across networks, regions, and ISPs.
Synthetic ground truth. Most benchmarks rely on WHOIS data or known landmarks as reference points — not the actual location of real users on real networks.
No geographic diversity. Testing from a single lab or datacenter captures one slice of network topology, missing mobile carriers, residential ISPs, and emerging markets entirely.
How IP Accuracy works
Device location ground truth. Every test uses the contributor's actual location as the reference.
Continuous and live. Rankings update as new tests are contributed. Accuracy trends are tracked over time, not frozen in a paper.
Real networks, real diversity. Tests come from residential broadband, mobile carriers, corporate networks, and hotspots worldwide — the actual conditions providers must serve.
Fully transparent. Open methodology, open scoring logic, open results. Anyone can verify the results, reproduce the analysis, or contribute tests.
Choose with data, not marketing
Stop relying on provider self-assessments. See real accuracy data before you commit to an API integration. Compare city-level precision where it matters most — in the regions you actually serve.
Benchmark against the field
Identify weak regions. Understand where your data excels and where it falls short compared to competitors. An independent benchmark gives your accuracy claims credibility that self-reported numbers never can.
Raise the bar for everyone
Transparent, crowdsourced measurement creates competitive pressure to improve. When accuracy is visible, providers invest in better data. The entire ecosystem benefits — better geolocation means better fraud detection, better compliance, and better user experiences.
See how accurate your IP location really is
Ten seconds, no signup, location never stored. You get a personal accuracy report — and every test strengthens the rankings.
