Caller ID Name (CNAM)
Add Caller ID Name (CNAM) to your workflow for U.S.-based phone number identity verification and fraud detection.
What is Caller ID Name (CNAM)?
Caller ID Name (CNAM) is a telephony feature used in the U.S. to display the registered name—person or business—associated with a phone number during an incoming call. It relies on telecom-managed Line Information Databases (LIDBs), where termination carriers perform lookups to retrieve the name.
Enrichment | Input fields | Signals returned | Coverage | Best for |
|---|---|---|---|---|
| CNAM | U.S. phone number |
| U.S. only | Caller identity validation, fraud detection, case enrichment |
How it works
- Telecom data sources: CNAM records come from Line Information Databases (LIDBs) managed by telecom providers or aggregators.
- Lookup on call termination: Termination carriers perform a lookup at call setup to fetch the caller’s registered name.
- Integration in RiskOS™: Socure uses CNAM lookups as an enrichment to flag inconsistencies between user-provided identity and telecom-sourced records.
What you can do with CNAM
- Strengthen identity verification when combined with enrichments like Phone Verification or Sigma Identity.
- Improve fraud detection by flagging mismatches between input identity data and CNAM records.
- Support risk decisioning workflows by enriching evaluations with caller identity.
- Enhance case management and investigations with an additional identity signal for analysts.
Unique features
- Registered caller identity: Displays the authoritative name tied to a phone number.
- Telecom-sourced data: Pulled from LIDBs, not user-supplied metadata.
- Cross-signal consistency: Compare against other enrichments to spot anomalies.
- Operational auditability: Log CNAM results alongside other evaluation signals.
