How to Stop Unwanted Spam Calls

Everyone knows the frustration of when you answer the phone only to find out that it's just another spam call. While lawmakers have passed legislation to curb these issues, spam and robocalls are still a common place. As a small business owner, who has limited time, you can't afford to spend time trying to figure out whether a call is a scam or not.

That's why we have compiled this a list of things you can do to help reduce the number of spam calls you receive.

  1. Manually block the number
  2. Register for the National Do Not Call Registry
  3. Report Spam
  4. Download an APP to block spam calls
  5. Check with your Carrier

1. Manually block the number

We all know that once a spammer or telemarketer gets ahold of your phone number, there will be no end to their calls in sight. Thats why instead of waiting for them to call you yet again, you can take matters into your own hands by blocking the number directly after they call you.

If you have an iPhone, you can go into the log of your recent calls and click on the small "i"  icon next to the number.

Once you click on this it will take you to the information page for that caller. At the bottom you will see a red button labeled "block this caller". Once you hit that button, you will no longer receive any communication from that number.

If you have an Android phone, to block a number you must navigate to your recent calls list and then tap and hold the number you wish to block. A menu will appear and will include an option to block calls from this number in the future (the exact button will vary by model).

2. Register for the National Do Not Call Registry

The National Do Not Call Registry is a database maintained by the Federal Trade Commission (FTC) that lists the telephone numbers of people that explicitly do not want to be contacted by telemarketers. You can follow these simple steps to put your number on the registry in less than five minutes.

  1. Go do and click on the icon that says "register your phone." You can first check if your number is already in the registry. If not then you can click on the "Register Here" button.
  2. You will be prompted to enter up to 3 phone numbers that you wish to register as well as your email where further instructions will be sent.
  3. After submitting a request, check your email and you should see an email titled "Register"
  4. Click on the link sent in the email to confirm your registration. You will then be directed to a page where you can print out a confirmation that your number is now registered.

However, please note that there are certain exceptions to the National Do Not Call Registry such as calls from non-for-profits and political organizations.

3. Report Spam

If you have a bit more time on your hands and are interested in doing a service for others that are also annoyed by spam calls, you can report any unwanted calls to the National Do Not Call Registry. In order to report sales calls, your number must be in the registry for at least 31 days, though you can report a robot call (a call with a recorded message instead of a person) without having your number on the registry at all.
