The location associated with the IP address they see may not be your physical location by quite some margin.<p>If you are connecting via a mobile phone the address is likely to be registered as at one of the phone company&#x27;s locations which could potentially be in a different state. For many home&#x2F;office serving ISPs this is similar. Also, if you are using a VPN of some sort the address you present to the web server is quite disconnected from your physical location.<p>If on the other hand they request your location via your web access client and you agree, it will be using localisation APIs that may well know your location with some precision: using GPS if your device has it and has it turned on, or via wireless AP availability based lookups otherwise.
