How to Request a PAC Code

This guide will show you how to request a PAC code for your mobile phone SIM card.

What is a PAC code?

A PAC (porting authorisation code) is a short string of letters and numbers that allow you to keep your mobile number when you change your provider.


An example of a pac code is: ABC123456

How to request a PAC code

Follow these steps to request a PAC code for your mobile number

1. Ensure you can text from the number you wish to port

Put the SIM card with the associated number in a mobile phone.

2. Text 'PAC' to 65075

To request a PAC from your existing provider, text the word PAC to 65075. The provider will then send an automated reply with your PAC as well as details about early termination of your contract. Be aware that there may be charges associated with the cancellation of your contract.

3. Give the PAC to your new provider

Let your new provider know your PAC code. If you're moving your mobiles to Bytes Digital, give our mobiles team a call and they'll assist with the number migration to ensure a smooth transition.

4. Wait for the number to migrate

Your mobile number should port to the new network within one working day of completion of step 3. This may take longer, depending on providers.

You may experience 'split service' for a couple of hours between the switch over. This means that the number is midway through changing and so you won't have any cellular or mobile signal for a brief time period. If your split service persists, contact your new provider.
