SENDER IDS

International Registration of Sender ID for Australia

If your organisation sends SMS messages to Australian mobile numbers but does not have an Australian Business Number (ABN), you can still register and use alphanumeric Sender IDs in Australia.

However, the registration process is different.

Under Australia’s SMS Sender ID Register framework, organisations without an ABN must use the Certified Telco pathway. This additional layer of verification helps protect Australian consumers from SMS impersonation scams while enabling legitimate international organisations to continue using trusted Sender IDs.

Modica is an ACMA-approved Certified Telco and can support eligible international organisations, software providers, messaging platforms, aggregators and global brands that need to register Sender IDs for use in Australia.

Can International Organisations Register Sender IDs in Australia?

Yes.

International organisations can register Sender IDs for use when sending SMS messages to Australian recipients, even if they do not have an Australian Business Number (ABN).

This includes:

  • International businesses
  • Global brands
  • Software providers and SaaS platforms
  • Overseas government agencies
  • Educational institutions
  • Charities and not-for-profit organisations
  • International messaging providers

The organisation must be able to demonstrate a legitimate connection to the Sender ID being registered.

What is a Non-ABN Organisation?

A non-ABN organisation is any organisation that does not hold an Australian Business Number.

Common examples include:

  • Overseas companies
  • International brands
  • Foreign subsidiaries
  • International messaging providers
  • Global software platforms

While these organisations may not have an Australian business presence, they can still communicate with Australian customers and register Sender IDs through the appropriate ACMA-approved pathway.

Why Do Non-ABN Organisations Need a Certified Telco?

Under the ACMA Sender ID Register framework, organisations without an ABN must use the Certified Telco pathway.

This means registration and compliance activities must be supported by an ACMA-approved Certified Telco such as Modica.

This requirement exists to:

  • Verify the legitimacy of international organisations
  • Confirm authorised representatives
  • Validate ownership of business names, domains and trademarks
  • Reduce the risk of SMS impersonation and fraud
  • Maintain trust within the Australian messaging ecosystem

For many international organisations, working with a Certified Telco is the simplest and most efficient way to meet these requirements.

What Information Will I Need?

Requirements vary depending on the organisation and use case, however international organisations are commonly asked to provide:

1. Organisation Information

  • Legal business name
  • Country of registration
  • Business registration number
  • Registered business address
  • Organisation website
  • Main business phone number

2. Authorised Representative Information

  • Full name
  • Position or role within the organisation
  • Email address
  • Phone number

3. Sender ID Information

  • Sender ID to be registered
  • Intended business use case
  • Evidence showing the Sender ID is connected to the organisation

4. Ownership Evidence

Depending on the Sender ID being requested, evidence may include:

  • Registered trademark information
  • Domain ownership
  • Business registration records
  • Brand ownership documentation

Additional information may be requested if further verification is required.

Identity Verification Requirements

For some registration types, identity verification checks are required.

These checks help confirm:

  • The identity of the person requesting registration
  • That the person is authorised to act on behalf of the organisation
  • That the organisation is legitimate and appropriately registered

Where identity verification is required, it must be completed through an approved Identity Verification Service.

Alternative approaches, such as notarised letters, are generally not accepted as a replacement for identity verification requirements.

International Partners and Messaging Providers

If you are an international messaging provider, SMS aggregator, CPaaS provider or software platform sending SMS traffic into Australia on behalf of customers, additional requirements may apply.

These requirements may include:

  • Partnership arrangements with an Australian Certified Telco
  • Authorisation requirements
  • Customer validation requirements
  • Sender ID ownership checks

If your organisation sends SMS messages on behalf of other businesses, we recommend reviewing our:
