Privacy matters and we understand this. Interphone is committed to protecting your privacy and keeping your personal and financial information safe and ensuring the security and access of your data. To help manage your account and services, you do have the option of enabling others authorisation for your account to act on, or access account information.

Adding someone to act as an authority for your account

The person whose name is on the account is known as the ‘Legal Lessee’ or ‘account holder’. Legally, this person is financially responsible for the account and there can only be one.

However, the account holder may authorise others to access the account and give them authority to act on that account at various levels. The selected level of authority determines their access and the actions they can or cannot take in relation to your account.

As an Interphone account holder, you may want a family member, friend or associate to act on your behalf and, for example:

  • Provide a spouse with access to your account
  • Give your child authority for billing inquiries on your account, or
  • Add a power of attorney to manage an account on your behalf.

Note; the account holder retains full responsibility for the account, and is responsible for the actions of the authority.

If you’re an account holder and you want to add an authority to your account, you can call us on 1300 301 337.

Full Authority

  • Must be 18 years or older
  • Has full authority over your account including authority to set up new Interphone services and products on your account, change account details, cancel services and access your Interphone bills
  • Isn’t financially liable for the costs and debts incurred on your account, unless there is some other legal, contractual, or family relationship which states otherwise

Verification of a person acting as an authority

To add an authority to your account, you’ll need to provide us with their full name and date of birth.

It’s important that you ensure these details are correct, as in future, when we need to use them to verify their details and allow them access to your account, the information given must be a match. If we’re unable to verify the full name and date of birth given to us they’ll be unable to take action on the account until the account holder has updated their information.
