Number Porting

Port your telephone number to TTNC

What does porting a number mean? Number Porting means transferring the management and billing of a telephone number from one service provider to another. This means you can keep the same telephone number but change your service provider.

If you have a telephone number that you'd like to move to TTNC, you would port it to us.

  • It costs £25 +VAT per submission when requesting to port a number. Once a number has been ported to TTNC, you pay £20 a year to renew the use of that number.
  • It takes between just 7 and 10 working days for a number port to complete. *
  • Your number stays active with your old provider right up until it switches to us. There's no downtime; we simply let you know once the port is complete and we've taken responsibility for your number.

      * Based on porting a single number. Porting multiple numbers can take longer.

Why port a telephone number to TTNC?

  • You want to keep your phone number because you're moving, or just don't want to pay line rental anymore.
  • You want lower call forwarding charges and to save hundreds of pounds a year.

What happens behind the scenes?

Without getting too technical, here is how the Number Porting process works:

  1. The end user (the user of the telephone number, you) fills out the relevant porting forms required by the gaining provider (such as us, TTNC).

  2. The gaining provider then communicates with the losing provider (such as BT), passing on the request to port away from them.

  3. The losing provider verifies that the porting request is valid.

  4. Following this validation they then agree to the porting request with the gaining provider.

  5. Once the gaining provider has this agreement in place with the losing provider, they can then prepare the services needed for the number being ported ready for the agreed porting time.

  6. At the agreed time, the losing provider ports the number to the gaining provider. This change of provider is updated on the UK public network so all calls will be forward to the gaining providers network.
