Block Phone Number: Unsolicited Phone Callers Beware!

Man receiving an annoying, unsolicited phone callWhat to do, and what not to do? Do not call the number back, and do not give out any of your personal information. Sometimes, merely calling a number back will verify that you are accessible and expose you to more risk. Some phone companies have blocked phone number listings you can use. Ask them to add the number that called you to your account (or use the automated service to do it yourself). Here are some common providers that offer this service:

Block phone number services by provider

First, you’ll want to block the phone number from calling you again. Each service provider has its own way of doing so. If you use AT&T, CenturyLink, Comcast, Time Warner Cable (TWC), or Verizon take a look at this article and follow the instructions to block a phone number. Here’s a list of phone providers and the maximum amount of numbers you can block through them.

  • AT&T Call Blocking – 20
  • CenturyLink Call Rejection – 25
  • Comcast Call Screening – 12
  • TWC Call Blocker Accept and Call Blocker Select – 30
  • Verizon Call Block – 12

After you’ve block the phone number it should prevent the call from coming through. However, if you are unable to use Caller ID blocking, we recommend you simply ignore the phone calls.

Next (or if you’ve already done that), visit the FCC website and report it there as well. You’ll be asked (via an online form) how you received the call (home, work, or cell phone), whether or not the caller left a message, details regarding the nature of the voice mail, how many times the call has occurred and when, and more.

Taking preventative measures

After reporting your call using the steps mentioned above, register your phone number with the government’s Do Not Call List. Note that phishing calls are not affected by the government’s Do Not Call List, as they are not legitimate telemarketing calls to begin with, and often originate from a location outside the United States.

Do all this and you’ll be on the way to helping us millions of people suffering hours and days of wasted time answering annoying, threatening, and malicious phone calls. Here’s to one day living in a world where our phone rings only when we want it to!

    Reporting number 916-222-2344

    The caller first left a voicemail stating his name was Dave Thomas, right. He had a thick foreign accent stating I was eligible for a loan ranging from $1,000-$10,000. When I called the number back he stated he was from Eloans and gave his name as somebody Nelson.

    When he asked who was calling I gave him a fake name and he supposedly looked it up and still said I was eligible. I told him I had not applied in many years and was not interested because I did not do business with foreigners, I contacted the company and left a message for them about this person.

    It sounded like the same dude that has called four times in the last three days about a payday loan from American Payday Loans, with a different number (305-242-1252 and 209-560-6999).

    • Thanks for sharing this with our readers “Polly”, hopefully this will help others avoid this scam!

    I received a phone call yesterday from 631-925-2199 yesterday & they left a voice mail. The message, however, did not give a company name – they want me to call back if I want to be on their no-call list. Scam? Mining for data? Either way, I blocked it on my phone. Anyone else get messages like this?

    Thanks for posting these tips and the links at the end of the article. I haven't had a land line in over 8 years, so I've been receiving unsolicited phone calls on my mobile. Considering how much I pay for mobile service, it's really annoying to get these calls, and especially the voicemails with nothing in the message. Thanks again and keep up the good work!

    I've been receiving random phone calls with area codes from cities across the US. They never say anything or leave a message, so I'm not sure what's going on. Thank you for posting the Do Not Call link – I just registered. I hope it works!

    I recently called an internet service to set up a wireless router – they only specialize in internet (no cable) so they transferred me to a "confirmation specialist" who really was a satellite TV sales person. He tried desperately for 20 minutes trying convince me as to why we needed cable TV although I told him repeatedly we don't need or want it. Then he said "can I call you back later after you've had a chance to think about it" and I said no, but he did anyway. I guess since he has my phone number from Caller ID and from my internet order he was able to track the call back. I haven't heard from him since, but just wanted those of you who are shopping via phone for services to be aware!
