They call and hang up: why it happens and what to do

Your phone rings once or twice, and when you answer there's nobody there, or the call drops right away. These "phantom calls" are a common complaint, and the NoCall community keeps a database of user reports on numbers that behave this way.

1. What's behind these calls

  • Autodialers: a telemarketing call center dials more numbers than it has agents available; if nobody's free when you pick up, the call drops.
  • Active-line checks: systems that confirm your number works so they can call you later or sell the list.
  • One-ring scam (wangiri): a deliberate missed call to get you to call back an expensive international or premium-rate number.

2. Don't call back yet

Be careful with foreign numbers. If the missed call comes from a country code you don't recognize, don't call back: the one-ring scam depends on you taking the bait and dialing a number that bills you by the minute. Be just as careful with unfamiliar area codes: some that look domestic belong to other countries.

3. Check the number on NoCall

Look up the number in NoCall's database. If other users report the same "call and hang up" pattern, you know it isn't a call worth returning.

4. Block and report

Block the number from your recent calls and report it in the NoCall spam numbers directory to warn other users. If the calls keep coming from different numbers, turn on automatic filtering and read our step-by-step guides. If they're sales calls, add your number to the National Do Not Call Registry: it cuts down on legitimate telemarketing, although scammers ignore it.

Why do they call me and hang up right away?

Most often it's a telemarketing autodialer with no free agents, or a system checking that your line is active so it can call you later. It can also be the start of a one-ring scam.

Should I call back if they call and hang up?

No, especially if the number is foreign or unknown: calling back is exactly what the one-ring scam wants, because it connects you to an expensive international or premium-rate number.

How do I stop getting hang-up calls?

Block the number, turn on your phone's spam filter, and report the number on NoCall so other users know it's a phantom-call line. You can also report unwanted calls to the FTC at ReportFraud.ftc.gov.

Received a suspicious call?

Look up the number in NoCall before sharing data, calling back, or clicking any link.

Search a phone number or a company name (Bank of America, Verizon and AT&T...) to check if it has been reported as spam.
