What is a restricted phone call?
Definition
A restricted phone call is a call where the caller has hidden their phone number, so your screen shows a label such as "restricted", "private" or "unknown" instead of a number.

When someone places a call, their phone company normally sends their number along with it, and your phone shows it as caller ID. A restricted call is one where the sender has blocked that. Your screen shows a word instead of a number. The exact word depends on your carrier and phone.
Hiding your own number is legal and often harmless. The FCC says you can block your number on calls you make, and that doing so is not spoofing. A doctor calling from a personal mobile might do it, and so might someone who doesn't want a stranger to have their number after a one-off call. Phone companies are required to offer this blocking, either for every call or call by call.
Why scammers like it
The same feature helps people you don't want to hear from. A caller with no number can't be called back, can't be looked up and can't be matched against a list of known spam numbers. Debt collection scams, fake bank or tax calls and silent robocalls all show up this way.
A restricted number is not proof of a scam, though. Plenty of hospitals, government offices and workplaces hide their numbers on purpose.
Restricted vs. spoofed
Restricted means the number is hidden. Spoofed means the number is faked: the screen shows a number, but it isn't the real caller's. The FCC treats spoofing with intent to cheat or cause harm as illegal. A restricted call is honest about one thing: it doesn't show you anything.
That difference matters for what you trust. A familiar-looking number can lie. A blank one tells you nothing either way.
How to protect yourself
- 1
Don't give details to an unknown caller
If a restricted caller asks for a code, a card number, a password or your date of birth, hang up. Real banks and agencies don't need them from you on an unexpected call.
- 2
Call back on a number you already trust
If the caller says they're from your bank or an agency, end the call and phone the number on your card or the organization's own website.

Use your phone's call blocking and screening
Most phones and carriers can silence unknown callers or send them to voicemail. The FCC lists call blocking tools and carrier options in its robocall guide at fcc.gov.

Cut down on who has your number
Scam and sales calls often come from lists built from people-search sites and data brokers. Serus finds where your phone number is listed and removes it, which cuts down on calls that arrive with your name attached.

Frequently asked
Should I answer a restricted call?
You don't have to. If it's important, the caller can leave a voicemail. If you do answer, don't share personal or payment details.
Can I call back a restricted number?
Usually not. The number was hidden, so there is nothing to dial back. Your carrier may be able to help with repeated harassing calls.
Is it illegal to hide your number?
No. The FCC says you can legally block your number on calls you make, and that this isn't spoofing. Faking a number to defraud or harm someone is what's illegal.
How do I stop restricted calls?
Turn on your phone's setting to silence unknown callers, ask your carrier about blocking calls with no caller ID, and report scam calls to the FTC at reportfraud.ftc.gov.
