Displayed number
The number presented to your device. It may be accurate, altered, forwarded, or associated with a shared calling system.
CALLER ID SPOOFING
The number on your screen is a clue—not proof of who is calling.
A caller can manipulate the name or number shown on caller ID. Aya keeps that limitation visible so a familiar display never becomes a reason to share money, credentials, codes, or remote access.
WHAT SPOOFING CHANGES
A real phone number can appear on a fraudulent call.
Caller ID information travels with the call and can be altered before it reaches your phone. An impersonator may display the real number of a bank, government office, local business, police department, or family member even though the call originated elsewhere.
A reverse lookup can accurately describe the displayed number and still be unable to identify the actual caller. Aya therefore separates reported identity from scam behavior and repeats the spoofing limitation in its Decision Card.
Reported identity
A person, business, or caller label associated with that number by a configured source. It does not prove who initiated this call.
Call authentication
Network information may indicate how confidently a provider can attest to the caller’s right to use a number, but it does not prove honest intent.
Behavior evidence
Urgency, secrecy, payment demands, credential requests, and remote-access instructions can matter more than a familiar display.
VERIFY INDEPENDENTLY
End the call before using a trusted contact path.
If the caller claims to be your bank, use the number printed on your card or inside the official app. For a government agency, type its official website yourself. For a family emergency, call a saved number or another relative and use a private verification question.
Do not use a callback number, website, QR code, or link supplied during the suspicious interaction. A convincing name, logo, voice, or local area code does not replace independent verification.
- Never read a one-time security code to an unexpected caller.
- Do not move money to a so-called safe or protected account.
- Do not install remote-control software at a caller’s request.
- Treat threats of immediate arrest, shutoff, or account closure as pressure that deserves verification.
REPORTING
Report harmful spoofing and preserve the interaction details.
Save the displayed number, date, time, voicemail, message, and the organization the caller claimed to represent. Report suspected fraud to the FTC and caller ID spoofing or unwanted calls to the FCC when appropriate.
FAQ
Frequently asked questions
If the number matches my bank, is the call legitimate?
Not necessarily. A scammer can spoof a real bank number. End the call and use the number on your card, statement, or official app.
Does call authentication prove the caller is trustworthy?
No. It can add confidence that the caller was authorized to use a number, but an authorized caller can still be mistaken, compromised, or dishonest.
Can Aya reveal the true origin of every spoofed call?
No. Aya analyzes the displayed number and available evidence; it cannot guarantee attribution of a deliberately disguised call.
Check the evidence before you trust the caller.
