8 geolocation fields on every plan: country code, country name, registry, region, city, postal, latitude, longitude, and timezone. In May 2025 ipinfo moved region, city, postal, coordinates, and timezone into its $49/mo Core tier; we kept them all open on Free.
ipinfo tier data verified from ipinfo.io/pricing as of 2026-04-22.

region | California |
city | Mountain View |
postal | 94043 |

Geolocation is probabilistic. Here's how confident we are in each level of precision:
| Level | Source | Typical confidence |
|---|---|---|
| Country | RIR delegation files (authoritative) | >99% for announced IPv4 |
| Region | Registry data + authoritative geo feeds | 90–95% for residential, 70–80% for hosting |
| City | Authoritative geo feeds + ASN-based heuristics | 80–90% for residential, 50–60% for hosting/VPN |
| Latitude / Longitude | City centroid or ASN HQ | Accurate to the city, not the household |
| Postal code | Where available from registry or authoritative feed | Absent for many countries; never guess |
Do not use IP geolocation as the sole basis for identity decisions. It is a probabilistic signal best combined with device fingerprinting, phone verification, and payment-method geography.
RIR delegation files refresh daily at 06:00 UTC. Every IP-Atlas server picks up the new tables via a SIGHUP hot-swap — no restart, no dropped connections. You can verify the counts on our status page.
