KEEP YOUR EXISTING NUMBER

Move your business number to UKDDI

Submit the details of your existing number and current provider. We will confirm portability, costs and the documents required before any transfer is started.

Request a porting check
1

Check

We validate the number range, current provider and the account information needed for a matching port request.

2

Authorise

You approve the order and provide the letter of authority or latest bill required by the losing provider.

3

Schedule

Once accepted, we agree a port date and prepare your chosen SIP, phone or divert route before cutover.

4

Transfer

The number moves on the confirmed date. We monitor the route and verify inbound calling after completion.

Important porting information

Do not cancel your existing service before the port completes. The account name, installation address and postcode normally need to match the losing provider’s records. Complex multi-line, hosted or broadband-linked services may require additional checks.

Submitting a request does not guarantee that a number can be ported. UKDDI will confirm feasibility and charges before accepting an order. A porting-out administration charge of £25.00 per number, plus VAT where applicable, applies when transferring a UKDDI number to another provider, and minimum-term charges remain payable.
