How do I block unwanted callers?

Important notice

On Sunday 19th January we made this Last Caller Barring Feature FREE. This feature was previously chargeable at £3.25 per month

TalkTalk takes offers two call blocking services which can help you avoid repetitive nuisance calls.

The Last Caller Barring feature is the perfect way to stop nuisance callers. You can use it to simply block the last number to call you or you can enter specific numbers you’d like barred.

Now whenever someone tries to call you from a blocked number, all they will hear is a busy tone and you’ll no longer be disturbed with a call. You can block up to 10 different numbers using Last Caller Barring.

Homesafe: Report Unwanted Calls allows you to report serious and persistent nuisance calls. We will launch a formal investigation into the offending number and if we find evidence to suggest malicious behaviour, we will block the offending number from the network.

For more information on blocking unwanted calls, select a question from the list:

How do I report unwanted calls to Homesafe?

We take scam and nuisance calls very seriously, so if you have been receiving them, please don’t hesitate to report them to us. You can report aggressive and persistent marketing calls, persistent silent or abandoned calls or calls you think could be scams. To do this:

  1. Visit our Homesafe: Report Unwanted Calls online form
  2. Enter the number of the nuisance caller
  3. Enter your My Account username and password, your TalkTalk account number or the last 4 digits of your payment method and click Submit

Once we receive your request, we will start investigating with a view to blocking them at network level, if we can find evidence of misconduct. This means that number will no longer be able to call anyone who is with TalkTalk.

Unfortunately, we cannot block private residential numbers from the UK. If you have been receiving malicious calls from a private number, or prank calls, please read our section on Malicious Calls for further help. We will block suspected scam callers with the aim of protecting all our customers from potentially becoming victims.

Does it cost anything to report numbers to Homesafe?

No, this is a free service. There is no limit to the amount of numbers you can report and we will be happy to investigate any requests.
