Caller ID spoofing
The practice of deliberately displaying false or misleading caller identification information, sometimes called "neighbor spoofing" when the displayed number resembles the recipient's own, used to increase the likelihood the recipient answers the call. Illegal under the Truth in Caller ID Act when done with intent to defraud, cause harm, or wrongly obtain something of value, but not eliminated by that illegality.
Defined in 2 GAGE programs, which carry 15 distinct definitions of it. The wording above is taught in Senior AI Scam Defense.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.
The practice of falsifying the name or number displayed to a call recipient, so a call can appear to originate from a government agency, a familiar area code, or a trusted organization regardless of its actual source. Neither the displayed name nor the displayed number is evidence of who is actually placing a call, which is why the callback habit in this program always uses a number the beneficiary already had rather than one shown on a screen.
Falsifying the number or name shown on an incoming call or message so it appears to come from a trusted person or organization. Because the display can be faked, a matching caller ID is not verification; only a channel you initiate and source yourself counts.
A technique that allows a caller to display a false name and phone number on the recipient's caller ID screen, including the real name and number of a legitimate institution such as a bank. Because spoofing is trivial for a determined scammer, caller ID display provides no reliable verification of a caller's identity.
A technique that allows a caller to display any phone number on a recipient's caller ID screen, regardless of the number actually being used to place the call. A displayed number matching a real bank or agency provides no reliable verification, because the display itself can be falsified.
The practice of setting a phone call's displayed name and number to something other than the true origin of the call, exploiting the fact that the phone network's caller ID system was not designed to authenticate who is actually calling. A spoofed display can show any name and number the caller chooses, including a real bank's or agency's actual published number.

How job descriptions say it
Postings rarely use the textbook word. These are the phrases the careers map reads as asking for the competencies above.
Where the frameworks place it: FTC guidance; FinCEN elder financial exploitation advisory; OWASP Top 10 for LLM Applications; Google SAIF.
One interview question about it
A caller sounds exactly like a colleague and asks for a transfer. How do you tell a voice clone from a person, and what is the rule?
Asked of candidates for deepfake, voice-clone and scam recognition. Answering it in your own words is exactly how a GAGE topic is passed, and the credential records the pass where an employer can check it.
If you come from another field
Some backgrounds already carry this competency, and the readiness check gives credit for it.
- Elder services, social work, banking front line and fraud teams carries it as a claim to back up: Fraud patterns are familiar; the synthetic versions are new.
- Cybersecurity and IT carries it as a claim to back up: Threat modeling and control design transfer; the AI-specific threats are new.
- A computer science or software engineering degree carries it as a claim to back up: Security fundamentals are a course you took, not yet a control you ran.
