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.
