Why businesses port
Change provider. Keep the numbers customers know.

Reduce migration uncertainty
Clear checks, documentation and an agreed transfer plan before the change takes place.
Prepare the request
The right information keeps the port moving.
Porting depends on the information held by your existing provider matching the order. We will help identify what is required before submission.
Current provider details
The losing provider, account name and account or service reference.
Complete number range
The main billing number and every associated single number or DDI range.
Recent documentation
A current bill or other evidence showing the registered customer and installation details.
Authorised contact
Confirmation from someone authorised to request the transfer on behalf of the organisation.

Accuracy matters. A mismatch in the address, customer name or number range can cause the existing provider to reject the order.

Important to know
Porting is coordinated.Not instant.
Timescales and eligibility depend on the number type, current provider, order accuracy and any linked services. We confirm the practical details before committing to a migration date.
Do not cancel the existing service
The number must normally remain active with the current provider until the port completes.
Identify linked services
Broadband, alarms, payment terminals or other services may depend on the existing line.
Plan for business-critical calling
We will discuss routing, fallback and the most appropriate migration window for your organisation.
Before you submit a port
Business number porting questions.
We check eligibility, information and the destination service before a transfer is placed.
Can I keep my existing business telephone numbers?
Most eligible UK geographic, DDI and non-geographic numbers can be transferred. We check portability and the receiving service before an order is submitted. See how numbers connect to business SIP trunks.
How long does business number porting take?
Timescales depend on the number type, current provider, order accuracy and whether linked services need to be separated. We confirm the expected lead time after validating the request.
How much does number porting cost?
Charges vary by number type, range size and complexity. We confirm any porting charge before the order proceeds.
What information is needed to port a telephone number?
You normally need the current provider, account name, service address, account reference, complete number range and recent supporting documentation.
Should I cancel my existing telephone service before the port?
No. The existing number should normally remain active until the port completes, and any linked broadband, alarms or payment services should be identified first.
