The Corporate Telephone Preference Service (CTPS) is the central opt-out register for organisations wishing to opt out from receiving sales and marketing calls. As with TPS for residential numbers, it takes 28 days for the registration to become fully effective.  

Corporate subscribers include:

  • Limited Companies, PLCs & Limited Liability Partnerships in the UK
  • Any Partnership in Scotland
  • Schools & Hospitals
  • Government Departments and Agencies
  • other Public Bodies.


It’s free to register on the CTPS. You’ll need to renew your subscription annually, and we’ll notify you by email when the date’s approaching.

Renewal is quick and simple. You will be sent a written reminder of the numbers you have currently registered on the CTPS file asking if you wish them to remain registered. We require confirmation of this to ensure continued registration.

If you’re registering your organisation's phone numbers with the CTPS, you’ll need authority to do so.

Please be aware that registering business numbers with CTPS can reduce calls that may actually be useful for you or your employees.
