How to Protect Yourself from Spam Calls

Here are some steps to help protect yourself from these and other spam numbers:

Download apps like TrueCaller or WhoCalledMe to help identify and block spam calls automatically. These apps maintain a database of known spam numbers and can alert you before you even answer.

2. Register with TPS

The Telephone Preference Service (TPS) is a free service that allows you to opt out of unsolicited sales calls. Registering with TPS won’t stop all spam calls, but it will reduce them significantly.

3. Avoid Giving Out Personal Information

If you receive a cold call, don’t provide any personal information unless you’re sure of the caller’s identity. Be especially wary of callers asking for bank details, passwords, or personal identifiers.

4. Report Scam Calls

Reporting scam calls to organizations like ICO or Ofcom helps build a stronger case against scammers. It also provides authorities with more data to take action against these illegal activities.

5. Check with Your Bank or Utility Provider

If you receive a call claiming to be from your bank or a service provider, always call them back directly using the contact details from their official website. Do not trust the number given in the call.
