Published 2026-01-01 by WSTTM Team

Understanding the Spam Call Epidemic

Americans received over 50 billion spam calls in 2025, making spam calls one of the most persistent annoyances of modern life. But you don't have to accept them as inevitable. With the right strategies and tools, you can dramatically reduce or eliminate spam calls entirely.

Immediate Actions: Stop Spam Calls Right Now

1. Register with the National Do Not Call Registry

The National Do Not Call Registry is a free service managed by the Federal Trade Commission:

  • Visit donotcall.gov or call 1-888-382-1222
  • Register all your phone numbers (landline and mobile)
  • Registration is permanent and free
  • Legitimate telemarketers must check the list every 31 days

Important Note: This stops legal telemarketers but doesn't stop illegal scam calls. You'll need additional strategies for those.

2. Enable Built-In Spam Protection

For iPhone Users (iOS 18)

  1. Go to Settings → Phone → Silence Unknown Callers
  2. Toggle ON to send all unknown numbers to voicemail
  3. Important calls from numbers in your contacts will still ring through
  4. Calls from numbers you've recently called will also ring through

For Android Users

  1. Open the Phone app
  2. Tap the three dots → Settings
  3. Select Spam and Call Screen
  4. Enable Filter spam calls
  5. Turn on See caller & spam ID

3. Contact Your Phone Carrier

  3. All calls from numbers not in your contacts go to voicemail
  4. Check voicemail periodically for legitimate calls

Long-Term Prevention: Stop Spam at the Source

Protect Your Phone Number

Preventing your number from getting on spam lists in the first place:

Never Share Your Number Publicly

  • Don't post it on social media
  • Avoid online forms that don't need it
  • Use a secondary number for online shopping
  • Read privacy policies before sharing

Use a Google Voice Number

  • Get a free secondary number from Google
  • Give this out instead of your real number
  • Powerful spam filtering built-in
  • Easy to change if it gets compromised

Opt Out of Data Broker Listings

Data brokers sell your information to telemarketers. Opt out from major brokers:

  • Whitepages: whitepages.com/suppression
  • Spokeo: spokeo.com/optout
  • BeenVerified: beenverified.com/faq/opt-out
  • PeopleFinder: peoplefinders.com/opt-out

Be Smart About Forms and Surveys

  • Read the fine print about marketing consent
  • Uncheck pre-checked boxes for promotional calls
  • Use a burner email and phone number when possible
  • Never fill out sketchy online forms

Handling Spam Calls That Get Through

The Golden Rules

  1. Never answer unknown numbers: Let them go to voicemail
  2. Never press any buttons: Even "Press 1 to be removed" confirms your number is active
  3. Never engage: Talking to scammers, even to yell at them, wastes your time
  4. Always hang up immediately: Don't give them a chance to manipulate you

Block and Report

Every spam call you receive:

  1. Block the number in your phone
  2. Report to the FTC at ftc.gov/complaint
  3. Report to your carrier (text "SPAM" to 7726)
  4. Report in your call-blocking app

Special Cases: What About Important Calls?

Medical and School Calls

If you're expecting calls from hospitals, schools, or doctors:

  • Save their numbers in advance
  • Ask them to leave voicemail
  • Set up a temporary whitelist exception
  • Use conditional call forwarding

Job Hunting

When you're job searching and need to answer unknown numbers:

  • Temporarily disable strict call blocking
  • Check caller ID before answering
  • Let unknown calls go to voicemail first
  • Re-enable blocking after securing a job

Why These Strategies Work

Spam callers rely on volume. They make thousands of calls hoping to reach a few victims. When you implement these strategies, you:

  • Remove your number from spam lists
  • Make it unprofitable for scammers to call you
  • Protect yourself from increasingly sophisticated scams
  • Take back control of your phone

While no solution is 100% perfect, implementing even half of these strategies will dramatically improve your phone experience.
