Answers to Questions (FAQ)
What is phone number geolocation? (Definition)
Geolocation is the ability to position an element more or less precisely, here a telephone on Earth.
For a fixed telephone, it is a question of locating the house to which the line number is connected.
For a mobile phone, it is a question of locating the position of the device directly. This can be achieved by exploiting signals from telecommunications antennas, GPS satellites or other location technologies.
At the same time, from an international telephone number, it is possible to know the country of origin of the SIM card (this is not necessarily the place where the call was made).
How does phone number geographization work in France?
French phone numbers are semi-structured and use a double geographic code, the first with the numbers from 01 to 05, which delimit 5 main regions in France but also and ZABPQ sub-codes (around 500) which are used to locate a geographic area close to the original location of the landline number.
Example: All landline telephone numbers (excluding VOIP internet phone) can be geolocated for free.
This page allows you to locate a landline telephone number for free. This method does not work for mobile phones staring with 06 or 07 (Warning: geolocation of a mobile phone without the owner's permission is prohibited)
In 2023, ARCEP put an end to the geographisation of numbers so that they could follow their owners, even if they moved to a region with another prefix. The data is therefore valid as long as a request for a change of region has not been made.
To which regions does 01, 02, 03, 04 and 05 correspond to?
The 5 regions are distributed as follows:
01: Paris and Paris region
02: North West of France
03: North-east of France
04: South-east of France and Corsica
05: South West of France
The French territories of the Atlantic Ocean are in 05 and the Indian Ocean in 02.

What are international prefixes?
In order to contact international telephone numbers, a standard has made it possible to define a series of numbers identifying each country. USA is +1, United Kingdom is +44.
What is the difference between antenna-based and GPS-based geolocation?
Geolocation based on telecommunication antennas determines the position by measuring the signal strength of the antennas to which the phone is connected.
GPS geolocation uses a network of orbiting satellites that emit a signal to calculate precise positions to within a few meters.
In both cases, it is necessary to obtain at least three reference points to determine the position, this is triangulation.
