Why we would rather answer with an error than a wrong guess
A wrong answer that looks confident is worse than an honest failure. An error tells you to check something. A confident wrong guess tells you nothing is wrong.

Some IP address blocks are allocated and used in a way that genuinely does not support city-level resolution, and returning a guess anyway would be worse than being honest about the limit.
A response with fifteen decimal places of latitude looks precise. It is not accurate just because it has more digits than the method can actually support.
Elevation data behind /v1/elevation has been refreshed, improving accuracy specifically in steep and mountainous terrain where older data tends to fall short.
Dense cities tend to have detailed, well maintained address data. Rural areas often do not, and that gap shows up directly in geocoding precision and confidence.
A dataset announced with pride and never revisited degrades quietly. Borders shift, postal systems change, and time zone rules get amended by governments that do not send a press release.
A satellite internet connection can route traffic through a ground station far from the actual user, which makes IP geolocation for these networks noticeably less precise.
Calling a lookup AI-powered is a marketing choice more often than a technical disclosure. The question that matters is whether the answer is right, not what produced it.
A coordinate a few meters from a border can reverse geocode to either country depending on exactly how the border data is drawn. This is a genuinely hard case, not a bug.
A confidence score sounds precise. It is often just a number that lets a provider avoid saying plainly whether an answer is likely to be right.
Elevation data is not equally accurate everywhere. Flat, open terrain is easy to measure precisely, while steep or heavily vegetated ground is not.
An IP address identifies a network connection, not a physical address. Understanding that distinction prevents most IP geolocation disappointment.
Accuracy claims mean nothing without a method. Here is how reference addresses with known coordinates are used to check what a geocoder actually returns.
