How to Identify Spam and Scam Phone Calls

Every day, millions of people receive calls from numbers they don’t recognize. While some may be legitimate, many are spam or scam attempts. Learning to identify these calls can protect you from fraud and save valuable time.

Common Signs of a Spam Call

There are several telltale signs that an incoming call might be spam:

  • Unknown or hidden caller ID – Legitimate businesses typically show their name or number
  • Automated voice (robocall) – A recorded message instead of a live person
  • Urgency and pressure – Claims that you must act immediately or face consequences
  • Requests for personal information – Social security numbers, bank details, or passwords
  • Too-good-to-be-true offers – Free vacations, lottery winnings, or guaranteed loans

Types of Spam Calls

Robocalls

Automated calls that play a pre-recorded message. These are the most common type of spam call. In the US alone, Americans receive an estimated 4 billion robocalls per month.

Telemarketing Calls

While some telemarketing is legal, many calls violate Do Not Call regulations. If you are registered on a Do Not Call list and still receive marketing calls, these are likely illegal.

Scam Calls

These calls attempt to steal money or personal information. Common scams include IRS impersonation, tech support fraud, and fake debt collectors.

Spoofed Calls

Scammers can make their number appear as a local number or a legitimate business. This technique is called caller ID spoofing and makes it harder to identify spam.

How to Protect Yourself

  1. Never answer unknown numbers – Let them go to voicemail. Legitimate callers will leave a message.
  2. Use a reverse phone lookup – Search the number on WhoCalledMe.io to see if others have reported it.
  3. Register on Do Not Call lists – In the US, visit donotcall.gov. In the UK, register with the TPS.
  4. Block known spam numbers – Most smartphones allow you to block specific numbers.
  5. Never give personal information – No legitimate organization will ask for sensitive data over the phone.
  6. Report spam calls – Report numbers to the FTC, Ofcom, or your local authority to help others.

What to Do If You Answered a Spam Call

If you accidentally answered and engaged with a spam call:

  • Hang up immediately – do not press any buttons or say yes
  • Block the number on your phone
  • Report the number to help warn others
  • Monitor your accounts if you shared any information

Stay vigilant and always verify callers before sharing any information. Use tools like WhoCalledMe.io to check unknown numbers before calling back.
