Accepted Answer

With ForenShield: enter the number in international format (+1 555 123 4567 or +15551234567), then click 'Analyze'. The OSINT tool instantly returns the country, carrier, line type (mobile/landline/VoIP/prepaid), E.164 format and a risk score — without sending the number to any server.

Question 2

What information can be found for free about a phone number?

Accepted Answer

Our free OSINT tool provides for each number: the country and region of origin, the carrier, the line type (mobile, landline, VoIP, prepaid), the normalized E.164 format and risk indicators. VoIP and prepaid numbers are flagged as high risk in fraud investigations.

Question 3

How do I know if a phone number is suspicious?

Accepted Answer

A suspicious number shows one or more of these signals: VoIP line type (often used in scams), prepaid number, dialing code inconsistent with the caller's assumed country. Our OSINT risk score automatically aggregates these indicators to alert you to high-risk numbers.

Question 4

How do I identify a phone number's carrier?

Enter the number in international format in our phone OSINT tool. Carrier identification (carrier lookup) is based on ITU-T databases and covers major European carriers (Orange, SFR, Bouygues, Free, Vodafone, T-Mobile, etc.) and North American carriers. Accuracy is very high for European and North American numbers.
