What is number porting?

Number porting is the process of moving a phone number (such as your businesses phone number) from one provider to another.

You may have ported a number before without realising it when moving provider for your mobile phone contract. We also have a guide to switching mobile phone suppliers by text.

Reasons why you may consider porting a number:

  • Moving premises,
  • Changing supplier,
  • Upgrading to a different service such as VoIP.

How to port your business phone number to a new provider

The below guide will show you the steps you will and should take when porting your business number.

  1. Check your contract

    First, you need to check with your current provider that you are out of contract. Porting your number while in contract may result in early termination charges from your current provider.

    This will also be a good time to let your current supplier know of your intentions to port your number away (optional).

    Please do not cancel your contract before the number port is complete. This could result in your number being lost.

  2. Contact your new provider

    Next, you want to get in touch with your new provider ideally with a copy of your latest bill. Then they will discuss with you which phone numbers you would like to be transferred.

    Depending on your new provider, they may not be able to port all types of numbers. For instance, some suppliers may not support non-geographic or premium rate numbers.

  3. Fill in a Number Porting Form & Letter of authority

    Your new supplier will now send you a number porting form and a Letter Of Authority (LOA) – sometimes these may be the same document.

    On the documents, you will be asked for information such as your account details, installation address, port date and phone numbers you wish to port. Please make sure these details are correct, as incorrect information may cause your number port to fail, which other providers may charge you an admin fee if this happens.

    This document will also confirm if there are any charges to port your number. Many providers charge for porting your number, however we (Globe2) – do not charge to port national geographic phone numbers.

    Once you have filled in and signed the documents return these to your new supplier and they will place the order for your number port.

  4. Wait for confirmation

    Within 3 working days your new provider should be able to tell you if your port has been accepted by your current provider.

    If you number port has been accepted, then your port will continue on the port date selected.

    If your number port is rejected, then your new provider will confirm the reason why and may ask you to confirm the details submitted on the porting form and LOA. The new provider may require you to sign new documents if the information is incorrect.
    After the new provider has the correct information, they will replace the number port order.

  5. Check and cancel your old service

    After you have received confirmation that the number port is complete, we advise that you check to make sure your phone numbers are working and routing through your new provider. You can ask your new provider for help with this.

    After you have confirmed the phone numbers are working and routing through your new supplier, you can contact your existing provider and cancel any services that you no longer require.
