How Accurate Is IP Geolocation?

4 min read · Updated April 2026

Short answer: city-level most of the time, never street-level. Mobile users and Virtual Private Network (VPN) users routinely see results off by hundreds of miles.

How Does IP Geolocation Actually Work?

Every Internet Protocol (IP) address is allocated in a block to an organization — usually an Internet Service Provider (ISP). Regional internet registries manage these allocations. The American Registry for Internet Numbers (ARIN) handles North America; other regions have equivalent bodies such as RIPE (Europe) and APNIC (Asia-Pacific). You can look up the authoritative registry at iana.org.

Geolocation databases — maintained by companies like MaxMind, ipinfo.io, and Cloudflare — map these allocated blocks to the physical regions where ISPs have deployed them. That mapping is the foundation of IP geolocation.

The critical limitation: these databases map the ISP's service region, not your specific device location. If an ISP serves a metropolitan area from a data center downtown, every subscriber in that metro area may resolve to the same city coordinates — regardless of whether you live downtown, in the suburbs, or in a neighboring town.

How Accurate Is It?

Accuracy varies significantly depending on what level of precision you need:

Country level: ~95% accurate. This is the most reliable tier. Country-level IP geolocation is used by streaming services for regional licensing and is broadly effective. Errors at this level are usually caused by VPNs or misconfigured corporate networks.

City level: approximately 55–80% accurate. According to MaxMind's published geolocation accuracy documentation at maxmind.com/learn, city-level accuracy varies by country and ISP type. Dense urban markets with well-documented ISP infrastructure score higher; rural areas with fewer ISPs and less frequently updated routing data score lower.

Neighborhood or street level: not achievable with IP addresses. Any tool claiming to pinpoint your street address from your IP is either misrepresenting what GPS-derived data it is collecting via your browser, or is simply wrong. IP geolocation is structural — it maps network allocation regions, not physical devices.

Check what a typical website thinks your location is — compare it to where you actually are. The difference is often informative.

When Does IP Geolocation Get It Wrong?

Several common scenarios produce significant geolocation errors:

Mobile networks. Mobile carriers use carrier-grade Network Address Translation (NAT) to route thousands of users through a small pool of shared IP addresses. Your IP may resolve to a regional gateway city that is 100–300 miles from where you physically are. This is one of the most common sources of geolocation error for everyday users.

Virtual Private Networks (VPNs). When you use a VPN, your traffic exits through a VPN server. That server's IP — not yours — is what websites see. You appear to be in whatever city and country that server is located in. This is by design, and it is why VPNs are effective at bypassing geographic restrictions.

Corporate networks. Enterprise networks often route all employee traffic through a central location — frequently the company's headquarters city — regardless of where individual employees are working. A sales representative working from home in Phoenix may appear to be in New York if their company's headquarters is there. This is the mechanism behind the "Verizon Business FiOS" geolocation problem reported by home broadband subscribers who appear to be in a commercial hub.

Satellite internet. Services like Starlink use ground station gateways, and your IP may resolve to the nearest gateway location rather than your physical address. For users in remote areas, this can mean resolving to a city far from their actual location.

So What Does This Mean for You?

If you are on mobile or connected through a VPN and a website asks "Are you in [city X]?" with the wrong city — that is the network, not the website being broken. The site is reading the IP-level signal accurately; the signal just does not point to your actual location.

If location accuracy matters to you — for a streaming region lock, a delivery form autofill, or a localized service — switching off your VPN or moving to a different network (Wi-Fi instead of cellular, for example) will often resolve the discrepancy. Browser-based location (the permission-gated GPS or Wi-Fi triangulation via the Geolocation API) is a fundamentally different and more precise system that bypasses IP geolocation entirely.
