Question 1

How do I run OSINT on a phone number?

Accepted Answer

Enter the number in international format (+33 6 12 34 56 78 or +33612345678) and run the analysis. The tool shows the country, line type and risk scores, then offers prefilled search links to continue the investigation on the web and social networks.

Question 2

Does the tool identify a mobile carrier?

Accepted Answer

No, on purpose: with number portability a number can change carrier without changing prefix, so no local calculation can state it reliably. The tool does show the line type, a landline's region, overseas France and special ranges, derived from the French numbering plan. For other countries, it identifies the country of origin and format validity.

Question 3

How can I tell if a phone number is suspicious?

Accepted Answer

Several signals raise the risk score, each shown with its explanation: invalid format, premium 089 number, Caribbean +1 code ("one ring-3" callback scam), satellite network, telemarketing number, VoIP line, fake digit sequence… The 07 prefix is not a signal: it is an ordinary mobile range. Then check reporting sites (Tellows, Signal-Arnaques, Dois-je répondre) through the links provided.

Question 4

Is the number sent to a server?

Accepted Answer

No. The analysis runs in your browser and the history is stored there. Only the pivot links you choose to open send the number to the relevant third-party service.

Question 5

What is phone number OSINT?

Accepted Answer

Phone number OSINT (Open Source Intelligence) means gathering publicly available information: country of origin, line type, presence in directories or on social networks, fraud reports. It is used by investigators, SOC and CERT teams, and by individuals targeted by cold calls or scams.
