The short version
- Caller ID is a claim, not a fact — it can be spoofed to look like anyone.
- Urgency + secrecy + unusual payment = scam. Every time.
- Hang up and call back on the organization's official number. That one habit defeats
nearly everything below.
The ten tells
- Spoofed caller ID. The screen says your bank, the IRS, or a delivery service —
or a number one digit off from your own. The display name is trivially fakeable; the
voice on the line is what's real.
- Strange hours and repeat-dialing. Legitimate organizations call during business
hours and leave one voicemail. Pressure campaigns call at 9 PM, three times in a row.
- Urgent or threatening language. "Your account will be closed today."
"A warrant has been issued." Panic is the product — real institutions send letters.
- Asks for information they should already have. Your bank never calls to ask for
your password, PIN, or full Social Security number. Never.
- Payment by gift card or crypto. The single loudest tell. No business, and no
government agency, settles anything in iTunes cards. The reason scammers want them:
irreversible and untraceable.
- Generic greetings. "Dear customer." "Hello, account holder." An organization
you have a relationship with knows your name.
- No verifiable footprint. Search the number. A real business's number resolves to
a website, listings, reviews. A scam number resolves to complaint boards — or nothing.
- Call-center noise that doesn't match the story. A "federal agent" calling from
what sounds like a hundred-seat boiler room isn't a federal agent.
- Asks you to install something. Remote-access software ("so I can fix it for
you") hands over your device. No legitimate support call starts there.
- Gets defensive when questioned. Ask for a name, a department, a callback number.
Legitimate callers give all three without friction; scammers deflect, stall, or threaten.
Legit vs. scam, side by side
When in doubt, behave as if it's the right column.
| Signal | Legitimate caller | Scammer |
|---|
| Identity | Knows your name and history | "Dear customer" |
| Tempo | Happy to let you call back | Must resolve it right now |
| Payment | Normal channels you already use | Gift cards, wires, crypto |
| Information | Verifies with partial data | Asks for full credentials |
| Verification | Name, department, number — freely | Deflection or threats |
The verification habit that beats all of it
- Let unknown numbers go to voicemail. Real callers leave a coherent message.
- Search the number before calling back — complaint boards surface scam numbers fast.
- Contact the organization through its official channel — the number on your card,
statement, or their website. Not the number that called you, and not a number the caller
"helpfully" provides.

covers the setup in a few minutes.

Questions people actually ask
Can caller ID really be faked?
Yes — spoofing makes a call or text appear to come from a bank, an agency, or your own
area code. Treat the name on screen as a claim, not a fact.
How do I verify a number that claims to be my bank?
Hang up and call the number on the back of your card. A legitimate institution never
minds the callback; a scammer needs you to stay on the line.
Why gift cards and crypto specifically?
Nearly impossible to reverse or trace. That request alone ends the conversation — no
real business or agency settles a debt that way.
Where do I report a scam number?
Texts to 7726; fraud to ReportFraud.ftc.gov; numbers on our network to
our NOC.
