01 / Check the numbers
Tell us which business numbers you want to retain, who currently provides them and whether they form part of a larger range. We check eligibility and identify any services linked to the existing line.

A new phone service.
The number your customers know.
Keep eligible existing business telephone numbers when moving to MyBizPBX or a compatible SIP Trunks service. MBC coordinates the checks, authorisation and planned changeover so your customers can continue calling the numbers they already know.
THE PRODUCT SET
Keep your numbers. Plan the move. Stay easy to reach.
Number porting moves a telephone number from its current provider to a new calling service. It does not copy your old phone system, voicemail messages or call-handling settings. We plan those requirements separately, alongside the number move, so the new service is ready for the agreed changeover.
02
02 / Confirm the details
We explain the account information and authorisation required, usually including a recent bill and the details held by your current provider. Accurate information helps avoid rejected requests and repeat submissions.
03
03 / Agree the changeover
MBC submits the port request and coordinates with the providers involved. We keep you informed and confirm the transfer date once it has been accepted; a requested date is not a confirmed booking.
04
04 / Move, test and hand over
When the number transfers, we check inbound and outbound calling, caller ID and the agreed routing. Your main number, direct-dial numbers, menus and call groups are tested as applicable to the new service.
DESIGNED AROUND YOUR BUSINESS
Allow 10–14 days. Keep room for provider delays.
A typical planning allowance is 10–14 days after complete, correct details have been received and the port request is submitted. This is an estimate, rather than a guaranteed completion time. It can take longer if your previous provider causes delays, queries the account details or needs to resolve a rejected request. Number ranges and more complex arrangements can also need extra coordination. We will confirm the expected timescale for your move and update you if it changes.
- Keep the existing number service active until MBC confirms it is safe to end it
- Use account names, addresses and postcodes that match the current provider’s records
- Tell us about broadband, alarms, payment terminals or other services using the existing line
- Wait for an accepted transfer date before making firm plans around the changeover
Can we keep our existing telephone number?
Often, yes, subject to the number being eligible and the providers having the arrangements needed to move it. We check the number or range before confirming what can be transferred.
How long does number porting take?
Allow around 10–14 days after the correct details are complete and the request is submitted. It can take longer if your previous provider causes delays or queries the request. The actual date is confirmed after acceptance.
What information do you need from us?
We will ask for the numbers to be moved, your current provider, the account details they hold and the necessary authorisation. A recent bill can help identify the account and service. We will tell you how to provide the required documents; we do not need your account password.
Should we cancel our old telephone service first?
No. Keep the service active and speak to MBC before placing a cancellation order. Cancelling first can complicate the transfer or interrupt calls. We will help you check which services end as part of the move and which may need separate action.
Could moving a number affect our broadband or other equipment?
It can if those services depend on the same line or account. Tell us about linked broadband, alarm signalling, fax machines, payment terminals or other equipment so we can review the dependencies before the port is submitted.
Will there be any interruption on the transfer day?
There may be a short period when routing changes take effect. We plan the changeover and test the new service, but cannot promise a completely interruption-free transfer. Discuss any critical calling requirements with us in advance.
Does porting move our voicemail and phone-system settings too?
No. Porting moves the number. Extensions, greetings, voicemail, menus and other settings need to be configured on the new system as part of the agreed setup.
Can we choose a transfer date?
We can request a suitable date and discuss your preferred timing. The date depends on acceptance by the providers involved and is only confirmed once the port has been agreed. Review your current contract and any applicable exit charges before agreeing the move.
