About FindNumberLocation

What the site does

FindNumberLocation reads a phone number and shows what the number itself tells you. You see its country, line type, local time zone and the correct ways to write it. Where the data has them, you also see the region a number range was assigned to and the network a mobile range was first issued to.

The site has five tools. The Phone number location page gives the full reading. The Where is this number from page covers country and region. The Phone number validator checks one number or a whole list. The Phone carrier lookup shows the original network. The Potential spam calls page points out warning signs in an unknown caller's number.

The home page has one more step. Press Continue to open our web app, where you can ask the phone's owner to share where they are. The owner decides. No position appears unless they accept.

What it doesn't do

The site does not show who owns a number. It has no names, addresses or subscriber records.

It keeps no database of reported spam numbers. The red-flag check works from the number and the details you enter. A result with no flags does not prove a call is safe.

It does not query phone networks. The network shown is the one the range was first issued to, and the number may have been ported to another network since. There is no network data for numbers from the United States, Canada, Mexico or Argentina, and data for Brazil is thin.

A region is the area where a number range was assigned. The phone itself can be anywhere. Mobile numbers show a region in only a few countries, such as Brazil, Mexico, Argentina, the US and Canada. Some countries, France among them, show no region for any number.

Where the data comes from

Numbering data comes from Google's libphonenumber, released under the Apache License 2.0. We re-encoded its region, carrier and time zone files into smaller files the browser can load. A NOTICE file at /data/num/v9.0.40/NOTICE.txt lists our changes and points to the license text.

Number parsing and validation use libphonenumber-js, under the MIT License.

Street maps use OpenStreetMap data, © OpenStreetMap contributors, under the Open Database License (ODbL). OpenFreeMap serves the map tiles. The map design follows the OpenMapTiles schema, © OpenMapTiles, under the Creative Commons Attribution 4.0 license (CC BY 4.0). MapLibre GL JS draws the map and is released under the BSD 3-Clause License.

The dot map uses Natural Earth data, which is in the public domain. City and region positions are adapted from GeoNames, under the Creative Commons Attribution 4.0 license (CC BY 4.0). We matched them to region names and simplified them. A NOTICE file published with that data lists the changes.

The fonts are Familjen Grotesk, Public Sans and Martian Mono, under the SIL Open Font License. They are served from this site.

Numbering data describes how ranges were set up, and it can lag behind real changes. Naming a source does not mean its authors endorse this site.
