Porting a number to TTNC

Number Porting is the transfer of the management and billing of a telephone number from one service provider to another. This means you can keep your telephone number but change your service provider.

There are two ways to initiate a porting request, via the website, this will create a new account for the ported number, and the other via myTTNC, where the ported number is added to an existing account.

We can port a number from a provider we have an agreement with - currently we have agreements with more than 50 providers, covering the majority of UK telephone numbers.

To submit a porting request you'll need the following information:

  • The telephone number you wish to port;
  • The current provider of the telephone number;
  • The Account Number you have with your current provider;
  • The installation address for a physical number (or billing address for a virtual number);
  • The line type, whether it's single-line or multi-line;
  • The telephone number you will be forwarding to.

Account Details

We always recommend that you contact your current provider to confirm account details as any incorrect details will result in the provider rejecting the porting request.

New Customer - via website

To port a number into a new account, you will need to navigate to the Number Porting page on our website.

Firstly, you will need to check the current provider of the number and make sure we have a porting agreement with them.

  1. Enter the number you wish to port into the 'Look up provider information' box and click on Look up number
  2. Check the 'Display Providers' list and if the provider doesn't appear in the list please email porting@ttnc.co.uk for more information.
  1. If the provider is in the list you can then download and complete the 'Letter of Authorisation' and press `Begin your port submission'

Porting Form

The porting form is fairly straightforward, however, please ensure that all details are correct before submitting.

Common rejection reasons

Incorrect Address - The address is checked against the losing provider's records. It will be rejected if the address doesn't match or even if there is a typo in the postcode.

Associated Numbers - If there are any other associated numbers in your account and this isn't reflected on the submission then it will be rejected.

Single-Line / Multi-Line - If the line type is selected incorrectly the submission will be rejected.

Number Out Of Service - The number must be active and able to accept a call in order for the submission to be accepted and the porting process to be completed.

We recommend that you always contact your current provider before completing the form to ensure the details submitted match those of your provider.

  • Main Billing Number - If you have more than one number on your bill, one of these will be the main billing number, usually this will be the only number on the bill and the number you are wishing to port.
  • Are there any other numbers on the account? - All the other numbers on the same bill (Associated numbers) - If there are associated numbers they all must be ported at the same time or the numbers which aren't ported will cease.
  • Where do you want to answer your calls? - The forwarding destination for your ported number. This would usually be a UK Landline or UK Mobile.
  • Current Operator - The current provider for your telephone number.
  • Account Number - Your account number with your current provider.
  • Business or residential line? - Is the line installed at a business or residential address.
  • Installation postcode and address - This must exactly match your current provider's details.
  • Any extras on the numbers? - If you have Broadband or a PBX attached to the number, these will cease when the number ports.
  • Single or Multi-Line? - Mutli-Line means a large number of single-lines at the same address, PBX groups or lines terminating on equipment (e.g. ISDN)
  • Is this a Remote Call Forwarding (RCF) number? - RCF numbers are the same as virtual numbers.
  • Do you want to keep your Directory Enquiries entry? - If you have an entry in the BT Directory Enquiries we can take it over or it will be deleted when service ends with your current provider.

Porting Away from TTNC

While we're certain that we have the best network and control panel in the industry, we understand that you may want to port a number away from us.

The porting process is always initiated by the gaining provider (your new provider) who will send a porting request to us (TTNC). At this point we’ll be in touch with you to verify the details and check the request is genuine.

Once confirmed, we’ll raise the invoice for the porting away charge and accept the port request.

You'll continue to use our service right up until the number has left your TTNC account on the set date.
