SENDER IDS

What is an ACMA Certified Telco?

Australia’s SMS Sender ID framework places specific compliance obligations on organisations that send SMS messages using alphanumeric Sender IDs.

From 1 July 2026, businesses using Sender IDs to communicate with Australian mobile numbers must ensure those Sender IDs are registered and used in accordance with the ACMA SMS Sender ID Register framework.

Not all providers can support every registration pathway. Under the framework, certain registration activities can only be performed by ACMA-approved Certified Telcos.

Understanding the role of a Certified Telco is important for organisations that want to maintain compliant SMS delivery, protect their brand identity, and avoid messages being labelled “Unverified” or blocked.

An ACMA Certified Telco is a telecommunications provider approved to participate in Australia’s SMS Sender ID Register framework and support Sender ID registration for eligible organisations.

Modica is an ACMA-approved Certified Telco, Originating Telco and Transiting Telco, helping organisations register Sender IDs, meet compliance obligations, and continue delivering trusted SMS communications to Australian customers.

Why Does Certified Telco Status Matter?

Certified Telco status gives Modica the ability to support more than standard Sender ID registration requests.

It is especially important for:

Australian businesses that need to register Sender IDs for SMS sent into Australia
International organisations that do not have an ABN
Aggregators and messaging providers that send on behalf of multiple customers
Organisations that need help navigating ACMA registration and authorisation requirements

If you’re evaluating SMS providers, Certified Telco status is one of the clearest indicators that the provider can support Sender ID registration at the level required by the ACMA framework.

What Can a Certified Telco Do?

A Certified Telco can:

Register Sender IDs for eligible organisations
Support Sender ID registration workflows for different customer types
Participate in the ACMA Sender ID Register framework
Help organisations meet the requirements for compliant SMS delivery into Australia

In Modica’s case, our certification also supports our role as an Originating Telco and Transiting Telco, which is important for the way Sender ID traffic is handled through our network.

Why Does This Matter for Non-ABN Organisations?

If your organisation does not have an Australian Business Number (ABN), you cannot use every registration pathway.

Under the ACMA framework, non-ABN organisations must use the Certified Telco pathway.

This means a provider such as Modica can help eligible international organisations and other non-ABN entities register Sender IDs for use when sending SMS messages to Australian recipients.

As part of this process, additional verification requirements may apply, including identity verification, authorised representative checks, and evidence demonstrating ownership of the business name, trademark, domain, or brand associated with the Sender ID.

For organisations operating internationally, Certified Telco support is often the simplest and most compliant registration pathway.

What Does Modica’s Certification Mean for Customers?

For Modica customers, certification means:

We can support Sender ID registration through the appropriate ACMA pathway
We can help verify the information needed for registration
We can support both Australian and international use cases
We can help customers understand whether they need the Business or Associate registration path
We can assist customers who are sending on behalf of another organisation
We can support registration and compliance requirements for aggregators and messaging providers

If you’re using Modica to send SMS into Australia, our certification helps ensure the Sender ID process is handled in line with the ACMA framework.

What is the Difference Between a Certified Telco and Other Providers?

Not all messaging providers are able to support the same registration scenarios.

A Certified Telco is approved to participate in the Sender ID registration framework at a higher level than a provider that is only delivering messages.

This distinction becomes particularly important when:

Registering Sender IDs for organisations without an ABN
Supporting international messaging providers
Managing registration and authorisation requirements on behalf of customers
Navigating complex partner and aggregator relationships

Sender ID registration is no longer simply a messaging preference. It is now part of Australia’s regulatory framework for SMS delivery and brand protection.

Choosing a Sender ID registration partner is about more than simply submitting an application.

As an ACMA-approved Certified Telco, Originating Telco and Transiting Telco, Modica helps organisations navigate both the operational and compliance requirements of Australia’s Sender ID framework.

Customers choose Modica because we can:

Whether you’re sending SMS messages directly, managing communications on behalf of customers, or delivering messaging services at scale, Modica provides both the telecommunications capability and regulatory expertise needed to support compliant SMS delivery into Australia.
