TL;DR: If strangers are calling or texting to ask why you called them, scammers are probably faking your number as their caller ID. It doesn’t mean your phone is hacked. The FCC says to tell callers your number is being spoofed and that you didn’t call; scammers usually switch numbers within hours. Set a voicemail password, don’t answer unknown numbers, and file a complaint with the FCC if it continues.
What’s happening
Spoofing is when a caller deliberately falsifies caller ID to hide who they are. The FCC describes “neighbor spoofing”: making calls look local, often using real numbers that belong to ordinary people. Yours happened to be picked.
Your phone isn’t hacked, your carrier account isn’t compromised, and nobody is using your SIM. They simply typed your number into a calling system. It’s identity theft for caller ID only, which is annoying but usually short-lived.
What the FCC says to do
- Tell people who call you that your number is being spoofed and you didn’t call them.
- Expect it to fade: scammers often switch numbers quickly, so the problem may end within hours.
- Set a password on your voicemail, so nobody can access it by spoofing your own number back to you.
- File a complaint at consumercomplaints.fcc.gov if it continues.
Why your phone may now say "Spam Likely"
The FCC lets carriers block robocalls by default using reasonable analytics, and many label suspect calls as "potential scam" or "spam". When your number is spoofed in a robocall run, it can get flagged, so your genuine calls show up as spam on other people’s phones for a while.
What to do about that:
- Ask your carrier how to report a number that’s wrongly labelled or blocked. The FCC encourages providers to give blocked callers a way to fix it.
- Tell regular contacts (your kid’s school, your doctor) to save your number, so they see your name instead of a warning.
How to stay safe while it’s happening
You’ll probably get odd calls too, from people returning "your" call, or scammers testing you. The FCC’s own rules for unknown calls:
- Hang up if asked to "press 1 to stop calls"; it confirms your number is live.
- Don’t answer yes/no questions from unknown callers.
- Never give account numbers, your SSN, your mother’s maiden name or passwords to an unexpected caller.
- If someone claims to be a company or agency, hang up and call the number on your statement or the official website.
Is it illegal?
Under the Truth in Caller ID Act and FCC rules, spoofing with intent to defraud, cause harm or wrongly obtain something of value is illegal, with penalties of up to $10,000 per violation. Some spoofing is legal, such as a doctor’s personal phone showing the office number, or a business showing its toll-free callback number. Hiding your own number so it shows as "unknown" isn’t spoofing at all.
What you might change
- Your voicemail greeting: “If you got a call from this number you didn’t expect, it wasn’t me; my number is being spoofed.” Slightly awkward, very effective.
- Your carrier: ask about call-blocking and spam labelling. Some carriers can confirm whether calls actually originated from your line.
- Your number: only if it goes on for weeks. It’s a drastic step, and your new number can be spoofed too.
Spoofing vs being hacked
If you see calls or texts in your own history that you didn’t make, that’s different: someone may have access to your account or SIM. See SIM cloning signs and when your number is used to scam others, and add a port-out PIN.
