Can you track a mobile phone number’s current location just by entering the digits into a website? No—not from the phone number alone. A number can reveal useful numbering information, but precise current location requires an authorized device, account or network data source.
The word “trace” is used for several different things. You can trace the numbering information in the sense of identifying a country calling code or looking for public references to the number. You cannot turn the digits into arbitrary live GPS coordinates.
Normal consumer location services work because software on a device has permission to obtain location and share it, or because the owner signs into an account-based lost-device system. A telephone number is not a substitute for that authorization.
No. GPS/GNSS coordinates are calculated from navigation signals and other location sources. The telephone number is used by telecommunications systems to address calls and messages; it does not encode latitude and longitude.
If a website shows a precise map pin immediately after a number is entered, ask what technical system supplied that point. The digits alone cannot do it.
An international number can reveal its calling code and broad numbering region. For example, +91 is associated with India and +31 with the Netherlands. That is useful context, but somebody can keep the same number while travelling abroad.

Mobile numbers generally should not be treated as current-city identifiers. Fixed-line area codes can sometimes be associated with a traditional geographic service area, but a mobile device moves, roams and may keep its number after other account changes.

Carriers have network information unavailable to ordinary websites because they operate the infrastructure serving the device. Access to carrier-side information is controlled and is not granted to a member of the public merely because they know the number.
Network-derived location is also not necessarily the same as a GPS fix. Learn more in Can a mobile carrier locate a phone?.
Authorities and emergency systems can have legal and technical mechanisms that are not available to public lookup websites. What can be obtained depends on jurisdiction, urgency, device/network state and applicable process.
The existence of those mechanisms does not make a commercial “enter any number” page legitimate.
A search engine can find public web pages containing the number: business listings, advertisements, contact pages or reports. That is web indexing, not live device tracking.

Messaging applications can offer deliberate current/live location sharing. That works because the device owner chooses to share location through the app. Merely knowing the account name, telephone number or email address does not grant continuous GPS access.
If the missing handset belongs to you, use the official lost-device account associated with it and check any tracker that was already installed and configured. That gives you a real authorization path.

An IMEI identifies cellular equipment and a SIM/eSIM identifies a subscriber relationship. Those identifiers are important for network service, blocking and recovery processes, but they are not public GPS passwords. Read IMEI tracking explained and SIM and serial identifiers explained.
The search demand is enormous, which creates an incentive for fake progress bars, country-code maps presented as live locations, paid “unlock” screens and malicious downloads. The safest check is to ask where the current location data came from.

LocationOf receives location from Android devices on which its app has been installed and authorized. It does not use a phone number to activate GPS on an arbitrary device.
The public number information tool is intentionally limited to information that can honestly be derived from the number itself. That makes it useful for number/country-code searches without pretending the service can secretly locate a subscriber.
