A VPN is not a location changer, and the phrase covers four different things that people treat as one. An IP address estimate moves when your exit moves. A device position does not, because it comes from sensors in your hand. A permission decides which apps may ask for that position at all. And a saved city, delivery address or account preference sits in a database that neither of the first two touches. Once you know which of the four you are looking at, "the VPN didn't work" usually becomes a much smaller question.

The two claims that get merged

"Your location" means either where the internet thinks your connection comes from, or where the device physically is. Those are produced by unrelated systems with different failure modes. The first is an inference made by a third party from an address it was handed. The second is a measurement made by your own hardware and, in most cases, shared only after you allowed it.

How the IP estimate is produced

Nobody asks your router where it is. Providers build databases that map address ranges to countries, regions and sometimes cities, using registry allocations, commercial data purchases and measurements such as latency from known vantage points. The lookup answers a question about the block, not about the device using it.

That is why a VPN changes the answer instantly and why the answer is often wrong anyway: consumer connections are reallocated, mobile ranges are shared across a whole region, and a database may be months behind. The Geolocation API is a completely different mechanism, which is why the two numbers in front of you can disagree without either being broken.

How the phone knows where it is

Location services combine satellite fixes with the identifiers of nearby Wi-Fi networks and cell towers, matched against databases of where those radios are known to be. The operating system does the combining and hands a result to an app that asked for it. Sending that app's traffic through a server in another country does not move the radios, so the fix stays where the device is.

There is one subtle interaction worth knowing. If an app reads location from the network instead of the OS, a changed route can shift what it infers. That is rare in mobile apps and common in web pages, and it is the reason a browser page can report a city while the phone's own map shows your street.

Approximate permission is the middle case. It gives the app a coarser answer derived from the same sensors, which changes the detail without changing the routing at all.

Permission is the switch people are hunting for

If the goal is that an app should not know your position, the control is the operating system's per-app permission, not the VPN server list. Most platforms now separate precise from approximate access, and both are revocable per app. Browsers add a second grant layer per site, so a site you allowed months ago can request device location without showing a fresh prompt.

Revoking permission stops future access under the platform's rules. It does not delete a position the service already stored, and it does not change the IP estimate that any other site will compute from your connection. Those are three separate cleanups, and only one of them is a permission toggle.

Labels that come from an account

A city name on a page may be a saved preference rather than a measurement. Home address, preferred store, delivery default and time zone are account fields; changing your exit does nothing to them, and a service may keep showing the old value until it refreshes. Before editing anything, decide which of the three sources the label came from: a fresh IP estimate, a device fix, or a stored setting.

Test one variable at a time. Check the IP in the same browser whose route you changed, then read the app's permission state, then look at the account's own location setting. Changing all three together produces a result nobody can attribute.

Choose an exit for the network path it gives you, and treat any location change as a side effect on one of the four layers rather than a promise.
