Nuisance Calls

Purpose of this Code of Practice

TTNC is a Communications Provider and number range holder with more than 7 million telephone numbers allocated to us by Ofcom.

We take all reports of nuisance calls seriously and whether you're a TTNC customer or not. We want to help reduce the number of nuisance calls you receive.

If you've received an unwanted call and have reason to believe that the call is connected to one of our numbers or customers then here is some guidance on what you can do:

  • If you feel threatened or harassed by a call, you should report it to your local police service by calling the “Non Emergency" number - 101.
  • If you receive unsolicited sales or marketing calls then you should tell the business that is calling you that you no longer wish to receive calls from them. This should stop a lot of unwanted calls.
  • You can “Opt Out" of all unsolicited calls by registering with the Telephone Preference Service (TPS).
  • If you've already registered with the TPS and are still receiving calls, you can complain to them. They will escalate the breach to the Information Commissioners Office who have the power to fine any business in breach of the regulation.
  • If you've been the victim of fraud you should report it to Action Fraud. Action Fraud will issue you with a police crime reference number and investigate further. Details can be found on their website:
  • You can make a complaint to the relevant regulatory body if applicable.

Following your complaint, the police, a government agency, the Information Commissioners Office or your telecoms provider will use industry procedures to contact the number range holder to investigate further.

If a TTNC number has been used we will of course take action. But in nearly all cases we see, the TTNC number has been falsely used as the Caller ID and the calls did not originate from our network or our customers.

Although TTNC has no regulatory or enforcement powers, please let us know if you have any concerns about nuisance calls as we may be able to help you.

Please be aware that we do not and will not provide any details of calls or our customers under any circumstances, unless we are requested to do so by the relevant authority through standard industry procedures.
