No public prefix lookup can track a person or device in real time. This project explains numbering allocations, not people tracking.
What a number encodes
A calling code and possible area code come from numbering plans. They are not telemetry from a handset.
What would be required
Current location is a different kind of sensitive information and cannot be inferred from the number string.
Use the right tool for your own device
If you need your own device location, use its consent-based device account tools rather than a number lookup.
What a location result would actually require
A telephone number can label a contact. Location information requires a separate permitted source; typing digits into this prototype creates none.
Country calling code
What it supports: A numbering plan
Missing requirement: No device coordinates
Geographic area code
What it supports: An assigned area
Missing requirement: No current device position
A consent-based location share
What it supports: The location that was intentionally shared
Missing requirement: Consent and an actual sharing service
Your own lost-device account
What it supports: Available owner-device tools
Missing requirement: Access to the authorised account/service
If a service claims to track any person from a number alone, ask what data it measures and whose permission it has. NumInfo offers no tracking, surveillance or location service.
