SKILL / Identity
Plans: Pro & AgencyPhone Intelligence
Examine numbering, line-type and carrier information without presenting it as proof of the subscriber’s identity.
Read the step-by-step user guidePhone Intelligence is the Nexus Skill that answers what a phone number can and cannot tell an investigator. Given a number, Nexus establishes whether it is validly formed, which country and numbering range it belongs to, what line type it appears to be and which carrier context is publicly associated with it. The result is a sourced phone intelligence record that describes the number itself, deliberately stopping short of claiming who holds it.
What you get
A phone intelligence record: number validity, numbering plan, line type and carrier context, each sourced.
Using Phone Intelligence in an investigation
That restraint is the point. Numbering data is useful for triage: a number presented as a local landline that resolves to a VoIP range, or a carrier that does not match the country the subject claims to operate from, is a signal worth recording. But the same data says nothing about the current subscriber or device user, and Nexus labels it accordingly. Each element of the record — validity, region, line type, carrier — is stored with its evidence and date, so a later reviewer can see exactly what was observed and when.
In a case, Phone Intelligence supports a wider identity or fraud workflow. A number found on a business listing through Business and Place Intelligence, on a contact page retrieved by Public-Source Research, or in a complaint surfaced by Public Forum and Community Mentions can be checked here and added to the relationship graph as an identifier. The record then carries into a BLUF Situation Brief or PDF report as a described observation, with its limitations stated, rather than as an unsupported claim about who answers the phone.
Example objectives
Run the Skill directly, or describe the objective in your own words — these are the kinds of questions it is built to answer.
Ask Nexus
“Is the number on this invoice a valid mobile number, and do its carrier and region match the company’s stated location?”
Ask Nexus
“What line type and numbering context is publicly associated with the phone number in this case, and what does that not tell me?”
Ask Nexus
“Check the three numbers listed in the complaint and flag any that resolve to virtual or non-mobile ranges.”
How Phone Intelligence fits the investigation
A Skill is one move inside a case. The findings stay in the case file, where the evidence behind them can be checked, graphed and reported.
- 01
Choose or describe
Pick the Skill from the Skill Library, or describe the objective in your own words and let Nexus work out which Skills fit the question.
- 02
Review the evidence
Open the evidence record behind any finding and read the original public source before you rely on what it says.
- 03
Add to the case graph
Promote the people, organizations and identifiers you accept into the case relationship graph, straight from their evidence records.
- 04
Brief and report
Turn the case into a BLUF situation brief and, on Pro and Agency, into a structured PDF report with chain of custody.
Evidence before conclusions
What Phone Intelligence cannot establish
Nexus keeps supported findings, possible matches, contradictions and information gaps apart instead of blending them into one narrative. These are the boundaries Phone Intelligence states up front.
- Numbering, line-type and carrier data describe the number, not the person; they do not establish the current subscriber or device user.
- A number ported between carriers, reassigned or provisioned through a virtual service can produce context that no longer matches its history.
- Phone Intelligence does not place calls, send messages, locate a device or reveal subscriber identity. An unresolved number is not evidence of anything.

Frequently asked questions
What does Phone Intelligence tell me about a number?
Phone Intelligence tells an investigator whether a phone number is validly formed, which country and numbering range it belongs to, what line type it appears to be — for example mobile, fixed or VoIP — and which carrier context is publicly associated with it. Nexus stores each element with its source and the date it was observed. The record describes the number; it does not identify the person or business currently using it.
Can Phone Intelligence identify who owns a phone number?
Phone Intelligence does not identify the subscriber, the account holder or the person using a device. Numbering metadata describes the number’s range, line type and carrier context, and Nexus presents it as exactly that. Numbers are ported, reassigned and provisioned through virtual services, so even accurate carrier data can be misleading about the person behind it. Identity attribution needs separate corroborating evidence, which the investigator gathers and assesses within the case.
Which Nexus plan includes Phone Intelligence?
Phone Intelligence is worth a Nexus Pro plan when a case needs number validation, numbering range and carrier context recorded as sourced evidence rather than checked informally. Pro at €59 per month includes it among 43 of the 47 investigative Skills, and Agency at €89 per month includes all 47 plus end-to-end encrypted investigation notes.
Does Phone Intelligence contact the number or locate the device?
Phone Intelligence never places a call, sends a message or attempts to locate a device. Nexus records the numbering, line-type and carrier context that describes the number and nothing about the handset or its user. Review the result as an observation about the number, then assess whether it is relevant to a lawful investigation. Save useful records to the case and check any recorded custody events where custody is enabled.
