Understanding Robocalls

Robocalls are pre-recorded phone calls made by automated systems, also known as autodialers. These calls are made to many people at once and can be informational or promotional.

There are several different types of robocalls, including:

  • Informational robocalls are used to provide updates on things like school closures, weather alerts, and political campaigns.
  • Promotional robocalls are used for advertising products or services or to solicit donations.
  • Scam robocalls trick people into giving away personal information or money. These calls often pretend to be from a legitimate organization or government agency.
  • Spam robocalls are unsolicited calls made to random phone numbers to promote products or services.

Robocalls are made using automated systems, also known as autodialers, which can simultaneously cause many calls. These autodialers are programmed with lists of phone numbers to call and can also be programmed to leave pre-recorded messages on answering machines or voicemail systems. Robocalls can also be made using Voice over Internet Protocol (VoIP) technology, which allows calls to be made over the internet rather than through traditional phone networks.

State of Robocalls in the UK

In the UK, the Information Commissioner's Office (ICO) has reported that robocalls are one of the most common nuisance calls. According to the ICO, the UK receives billions of unwanted calls and texts yearly, with robocalls making up a significant portion of these. Many of these calls are made by scammers and fraudsters, who use robocalls to trick people into giving away personal information or money.

The UK government has taken steps to address the problem of robocalls, including creating the Telephone Preference Service (TPS), which allows individuals to opt out of receiving unsolicited sales and marketing calls. However, the effectiveness of TPS is limited as it only applies to live calls rather than automated calls.

The UK's regulatory body, Ofcom, is also taking steps to combat robocalls. They have introduced a framework that allows phone companies to block calls that are known to be unwanted and also encourage phone companies to make call-blocking technology available to customers for free or at a low cost.


Identifying Robocalls

There are a few signs that can indicate that a call is a robocall:

  • The call is pre-recorded and sounds robotic or automated.
  • The caller ID is blocked or shows up as "unknown."
  • The caller ID is a number that you need to recognize.
  • You receive multiple calls from the same number in a short time.
  • The call is unsolicited and is trying to sell you something or ask for personal information.
  • The call begins with a recorded message: "Hello, this is an important message for..."

You can check the caller ID for robocalls in a few ways:

  • Look up the number online to see if it is listed as a known robocaller or scam number.
  • Use a call-blocking app or service that can identify and block robocalls.
  • Check the caller ID on your phone to see if it's a number you recognize. If not, do not answer the call.
  • Ignore calls with numbers that are not familiar to you or that have been blocked.
  • If you answer a call you suspect is a robocall, hang up immediately.

Do Not Call Registry

You can register your phone number with the TPS, which makes it illegal for organizations to call you to sell goods or services. However, it is important to note that it will not block all robocalls, such as informational or scam robocalls. It only applies to live calls and not to robocalls pre-recorded or generated by automated systems.

Call Blockers to Stop Robocalls

A call-blocking device for your landline phone can be an effective way to block robocalls, as it can be programmed to block specific numbers or types of calls. You can also use these devices with other methods, such as registering with the TPS, to provide an additional layer of protection against robocalls.

Additionally, it's also essential to educate yourself about the latest scam tactics used by robocallers, and share it with your family and friends, so that they can also protect themselves from these unwanted calls.
