What is an AVC ID and why does it matter?

Last Updated: Wednesday 18 June 2025

An AVC ID (Access Virtual Circuit Identifier) is a unique code that identifies your nbn^® connection. 

Every nbn service has its own AVC ID. It’s a 15-character code that starts with AVC, followed by 12 numbers. For example, ‘AVC123456789100’. 

Why does this matter?

From April 2025, nbn^® requires you to provide your AVC ID in some cases, like when you're switching providers and taking over an existing connection. 

It helps: 

• Confirm you’re authorised to transfer the service 

• Avoid delays or incorrect disconnections 

• Identify the right connection when there are multiple services at the same address 

Only you and your provider can see your AVC ID. This helps protect your service from being transferred without your authorisation. 

How to find your AVC ID 

If you're already with Aussie Broadband: 

1. On your invoice

It’s listed on page two, next to your service address. 



2. In the MyAussie app or portal 

1. Log in to MyAussie

2. Tap Home

3. Tap Services

4. Choose your NBN service. The AVC ID will appear under or next to your service address 



If you're with another provider

Check your invoice or online account near your service address. 

 When signing up with Aussie, we’ll only ask for the last 5 digits.

• In your MyAussie app or online portal if you're already with us

Finding a customer's AVC ID

You can find a customer's AVC ID in your Carbon app. You can do this by navigating to Services -> NBN, and checking the AVC column on the table.



Inputting the AVC ID in Carbon

Note: You'll only need the AVC ID if you are transferring from a port or CPI (Copper Pair ID) that is currently in use.

1. In the port or CPI selection page a free text box will appear for you to input the AVC ID. You can either enter the last 5 digits, or the full 12 digits of the AVC ID.

   
   

2. Click the Validate AVC button to check the AVC against NBN’s records.

   • If valid, you will be able to continue with the service transfer as per normal
     
     

   • If invalid, you will be asked to try again.
     
     

3. If you do not have or know the valid AVC ID, you can upload documents to prove the residency of the customer as an alternative verification. However, please note that this will cause delays in the order processing times.
