How Accurate Is IP Geolocation?

What level of accuracy should I expect?

There is no universal IP-geolocation accuracy percentage. Results vary by data source, database date, network type, geography, and what a test counts as “correct.” A provider's percentage is useful only with its methodology, including the test sample, date, location level, and allowed error or radius; do not apply it automatically to another provider or a particular address.

Accuracy changes by network type and over time. Fixed broadband may map to the local service area of the company supplying Internet access, called the Internet Service Provider (ISP). Mobile networks and services that relay traffic, such as VPNs and proxies, may show the relay's location far from the user. A content delivery network (CDN) serves content through distributed servers. Its addresses, and anycast addresses served from multiple sites, may describe infrastructure rather than the user's location. Recent address transfers and provider reassignments can leave databases temporarily out of date.

How should I compare the location source rows?

IP Lens can display multiple source rows when location records are available. Sources with no usable record are omitted, so some results show one row or none. Compare the rows that are present instead of assuming every provider has an estimate. Start at country level, then move to region, city, and coordinates only while the rows remain consistent. Providers may reuse some of the same registry, routing, geofeed, measurement, or correction inputs, so agreement does not always mean independent confirmation. Use this quick reading guide:

No source is authoritative. Agreement supports a conclusion; disagreement is information about uncertainty, not a reason to pick whichever result looks most convenient. The source-conflict causes below explain the next checks to make.

What can IP location tell me?

IP location is best suited to coarse, low-risk decisions where an approximate result is useful but does not need to be exact.

Good uses of IP location

• Choose a user-adjustable default language, currency, or regional version.
• Route traffic toward a nearby service location.
• Measure aggregate regional demand for analytics or capacity planning.
• Use an unusual country or region as one signal for additional account verification.

Bad uses of IP location

IP location is poorly suited to precise, high-stakes, or identity-level decisions. It should not be treated as proof of where a specific person is.

• Pinpoint a street address, building, room, or person's exact whereabouts.
• Determine identity, citizenship, residence, billing address, or legal jurisdiction.
• Make an irreversible enforcement or abuse decision without stronger evidence.
• Replace device signals, authentication history, user confirmation, or other security controls.

The address may belong to a proxy, VPN, or CDN rather than the person, so confirm the real client IP first. Location databases often assign an estimate to a range of addresses. Addresses in that range do not necessarily represent devices in the same place. For example, a mobile network's addresses may serve phones spread across a large area.

How to phrase findings

Why Does My IP Location Show the Wrong City?

A wrong city usually means the result describes network infrastructure or a representative location for an IP prefix, not the device using the address. An ISP may map customers to a regional gateway, a mobile carrier may route them through a distant exit point, and a VPN, proxy, or CDN may expose its own location instead. Some databases also use a city center or another shared coordinate when they cannot identify a more precise location.

Providers combine different signals: registry records, routing data, latency measurements, traceroutes, geofeeds, corrections, and more. Because methods and update schedules differ, databases report different cities, coordinates, or accuracy radii for the same address. Dynamic reassignment can also leave an old city attached to an address after a provider moves it. For anycast services, several cities can be valid at the same time because the address is served from many sites.

These are network estimates, not direct measurements of a person. See why location sources conflict for the underlying causes and use the coarsest location they support.

How can I correct a wrong IP location?

First, confirm the public IP address and the time when the wrong result appeared. Home and mobile addresses may be shared or reassigned, so the address visible now may not be the one used earlier. Compare the rows on the IP Lens result to identify which provider has the incorrect value.

1. Submit the correction to the provider that supplies the wrong row. IP Lens combines third-party datasets and cannot change their source records directly.
2. Include the exact IP address or prefix, the correct country and region or city, and evidence that you operate or currently use the address.
3. If you operate many prefixes, publish a geofeed in the format defined by RFC 8805 and make it discoverable as described by RFC 9632. A geofeed is an operator-published hint, not proof. Consumers should verify that the publisher is authorized for the prefix and may compare it with other evidence before accepting it.
4. Allow for the provider's review and for IP Lens to import the next database release. Different rows may update on different schedules.

Use the official forms for MaxMind GeoLite corrections and IPinfo corrections. DB-IP accepts reports through the correction link on an individual DB-IP address result and documents the process in its geolocation FAQ. IP2Location documents an affidavit-based IP address change request.

What causes IP location sources to conflict?

After the row comparison shows a conflict, look for the underlying cause. A disagreement does not mean one source is careless: the sources can describe different facts, refresh at different times, or model shared evidence differently.

Which confidence signals should I use?

Confidence is not the same as precision. A precise-looking coordinate is less trustworthy than a broad country result if the sources behind it are stale or contradictory.

Some providers return an accuracy radius with their own city-level data. It is the provider's precision estimate around the reported latitude and longitude, not a measured error bound or a guarantee that a person is inside the circle. IP Lens does not currently display accuracy radii. If you consult one in the provider's output, interpret it with the coordinate and compare it with genuinely independent context such as known device history.
