How to Block Spam and Fraudulent numbers calling you in the UK using your phone


At times we receive unwanted calls it can be considered as a minor nuisance but in most cases, it turns out to be a total disturbance and may affect your life to extremes. We have seen some numbers continuously disturbing a person nonstop for couple of hours. It can occur in many forms, sometimes as a silent call, that keeps ringing one after another, sometimes marketing calls that keep on engaging our line for services or products that are not in our interest, or even it can be a call that will make us consider huge gains on investment and the scammer will request our bank details. 

These are only some examples, from pensions to insurance we should always keep in mind a genuine legitimate company only contacts people according to GDPR laws by the receiver's consent. Generally, cold call schemes break the law and call people with no permit and keep on connecting some lines in a repeated pattern. There are many ways to stop these suspicious calls and scams from contacting you, blocking the numbers, reporting to Ofcom and TPS, registering with TPS service, and using software systems to prevent spam calls are a few ways to protect yourself from these malicious intentions.

How to identify a spam call?

It is not always easy to identify a spam call, some calls will use names of organisations that are very well recognised by the public such as HMRC or NHS, and some others will start calls by asking if there was a recent accident or if you are happy with your pension scheme or if you are entitled to some compensation for PPI or similar natured concepts. These calls are being made to a large proportion of the public daily and their methods get updated further every day.

Usually, the purpose of the call is to trick the person into providing information regarding their finances or gather details of a requirement that may interest the person in the near future, as example, energy tariffs, car insurance, or IRS schemes, there are also options for scammers to get more effective data using robocalls if you engage with the call and press the indicated button to connect to someone that will increase the chance of you getting more spam calls. Therefore, it is best not to engage with these calls and blocking the caller using your smartphone is the first step you can take to prevent receiving more spam calls from these companies.

Engaging with any of the spam calls may also lead to your number being added to a general list that is being used by these companies referring as responsive, easy target and commonly active answerer. That makes you a more prospective target for spam callers and fraudsters.

How to block spam calls?

Most of the smartphones we use have a feature to block numbers unwanted or for UK numbers you can register to Telephone Preference Service (TPS) to remove numbers from the telemarketer's list. This is a free application and very straightforward. This registry at the moment is not effective on the robocalls but will support the reduction of spam calls being received.

We will also identify how we can use the feature of blocking calls in Android and iPhones and show you more options to explore for further protection.

Calls are not the only communication we receive from scammers, please also watch out for spam emails and text messages.

Is there a code to block spam calls in the UK?

Unfortunately, unlike other countries in the UK, there isn’t a specific code that can block all spam and robocalls, although Ofcom, Trading Standards and TPS are working on further enhancements to protect the public from spammers, identification of numbers has been the most difficult part due to internet numbers through VoIP phones being easy to get for a list to be pooled and identified. The opportunists change the number they are calling from as soon as it is determined to be a spam number. When new updates are announced we will keep our readers updated.

How to block spam calls using your iPhone

iPhones provide the option of blocking callers individually or disabling all calls from unknown numbers in one step. Blocking all unknown numbers may reduce the risk of receiving spam calls in general but sometimes we receive calls from legitimate authorities from unknown numbers in the UK, hence this is important to know that you will block all calls from unknown numbers which can turn out to be your GP Practice or it can be related to your tax affairs. 

If calls are individually blocked this will prevent you from blocking some of the genuine unknown number callers that may be important to you, or you may register with TPS and block individual numbers for a higher level of protection.
