How to Handle Unwanted Fundraising Calls from Unknown Numbers

Unwanted fundraising calls from unknown numbers can be a significant nuisance. Fortunately, there are several effective strategies to manage and block these calls:

What Is the National Do Not Call Registry?

The National Do Not Call Registry is a free service that allows you to opt out of receiving unsolicited sales calls. By registering your number, telemarketers are prohibited from contacting you. However, this registry does not block calls from charities, political organizations, debt collectors, or companies with which you have an existing business relationship. (consumer.ftc.gov)

How Can I Register My Number on the Do Not Call List?

To add your number to the National Do Not Call Registry:

  1. Visit DoNotCall.gov.
  2. Click on "Register Your Phone."
  3. Enter your phone number and email address.
  4. Confirm your registration via the email sent to you.

Alternatively, you can register by phone by calling 1-888-382-1222 from the number you wish to register. (consumer.ftc.gov)

What Are Call Blocking and Call Labeling Technologies?

Call blocking and labeling technologies help identify and block unwanted calls. Call blocking involves using software or devices to prevent unwanted calls from reaching you, while call labeling displays information about the call, such as "spam" or "scam likely," allowing you to decide whether to answer. (consumer.ftc.gov)

How Can I Block Unwanted Calls on My Cell Phone?

Most smartphones offer built-in features to block specific numbers. Additionally, you can download third-party call-blocking apps that maintain databases of known robocall numbers. These apps can automatically filter or identify known spam callers. Examples include RoboKiller, Hiya, and Truecaller. (consumer.ftc.gov)

What Should I Do If I Receive an Unwanted Call?

If you receive an unsolicited call:

  • Do not engage: Avoid pressing any buttons or responding to prompts, as this may lead to more unwanted calls.
  • Hang up immediately: Simply end the call to prevent further interaction.
  • Report the call: File a complaint with the Federal Trade Commission (FTC) at ReportFraud.ftc.gov. (usa.gov)

How Can I Report Unwanted Calls?

To report unwanted calls:

  1. Visit ReportFraud.ftc.gov.
  2. Provide details such as the date and time of the call, the caller's number, and any information about the caller.

Reporting these calls helps authorities identify and take action against violators. (usa.gov)

Are There Additional Measures to Reduce Unwanted Calls?

While no solution is entirely foolproof, combining multiple strategies can significantly reduce unwanted calls. Utilizing call-blocking technologies, registering with the National Do Not Call Registry, and reporting violations can collectively help minimize the impact of unsolicited fundraising calls.
