Virtual Phone Numbers Guide: SMS Numbers in Australia

Everyone has experienced receiving SMS messages from businesses, SMS appointment reminders, delivery updates, SMS service alerts, or SMS marketing offers. Because SMS is fast, familiar, and highly visible, it has become one of the most effective ways for organisations to communicate with customers.

If your business is looking to send messages like these, you’ll need more than a personal mobile phone. Australian businesses require an Australian virtual mobile number to send SMS broadcasts, transactional alerts, and two‑way messages at scale.

With an online phone number SMS solution, organisations can automate notifications, manage replies centrally, and communicate with large groups of customers all at once. Instead of relying on individual mobile devices and SIM cards, teams can use a virtual text message platform to deliver consistent, secure messaging across the business.

Virtual mobile numbers and Sender IDs give businesses flexibility in how messages are sent, whether that’s two‑way SMS conversations using a virtual SMS number, or branded one‑way SMS through a Sender ID. Together, these tools form the foundation of a reliable virtual SMS service built for modern business communication.

This guide explains what a virtual SMS number is, how virtual numbers in Australia work, and how Australian organisations use virtual phone numbers for SMS to send alerts, automate workflows, and stay compliant with local messaging regulations.

Virtual SMS Number Usage is Increasing

Despite the growth of apps and email, SMS remains one of the most reliable business communication channels.

Recent industry research consistently shows that:

• SMS open rates exceed 90%, often within minutes of delivery.
• Over half of Australian consumers prefer SMS for time‑sensitive business communication such as reminders and alerts.
• Missed appointments are reduced by 30–40% when SMS reminders are used instead of email or voice calls.
• ACMA (The Australian Communications and Media Authority) continues to report SMS as a high‑engagement channel by introducing new SMS laws and regulations regularly.

These SMS statistics and trends explain why businesses increasingly rely on virtual text message platforms rather than personal mobiles or legacy systems.

What is a Virtual SMS Number?

A virtual SMS number, also known as a dedicated virtual mobile number or virtual phone number, is just like a regular traditional phone number; it functions like a standard Australian mobile number but exists entirely online. Instead of being tied to a SIM card, the number is accessed through a secure virtual SMS service, allowing SMS messages to be sent and received via:

• A web‑based SMS inbox
• Business systems using a SMS API
• Workflow and SMS automation tools

With an online phone number SMS platform like Notifyre, teams can manage conversations collaboratively without relying on individual staff members’ devices. With 53% of consumers stating that SMS is their preferred form of communication, adopting a virtual SMS number allows businesses to engage with their audience through a channel they already trust and actively use.

What Types of Virtual SMS Numbers are Available?

In Australia, there is one primary standard type of virtual SMS number used for business messaging: the Australian virtual mobile number (10‑digit numbers). An Australian virtual mobile number is the standard number type used for both SMS and MMS business messaging. 

Short codes (e.g. 4–6 digit numbers) exist in Australia bu they are expensive, require lengthy carrier approvals, are typically reserved for very large enterprises or government programs. For the vast majority of Australian organisations, virtual mobile numbers replace the need for short codes.

Traditional Mobile Number vs Virtual SMS Number

There are several benefits a virtual SMS number can have on your business communications. At a glance, a virtual SMS number can lower SMS costs, provide an easy way to reach your entire audience. It can also improve overall business communications by integrating SMS into existing business workflows with SMS API or Notifyre's Zapier SMS integration. 

Here are the benefits and reasons why your business needs a dedicated virtual phone number.

Virtual Phone Number Compliance

SMS messaging in Australia is regulated under the Spam Act 2003, with enforcement by ACMA. In 2026, businesses are expected to demonstrate clear compliance, not just intent. While it’s technically possible to send SMS messages from a mobile phone using a SIM card, this approach quickly breaks down for businesses, particularly when compliance, scale, and accountability are required.
A virtual SMS number, combined with an online SMS service, is designed specifically to solve these challenges.

Managing business messages from a physical mobile phone creates several risks and inefficiencies:

• Messages are tied to one device and one person
• Consent and opt‑out requests can be missed or inconsistently handled
• There is no reliable way to retain message records if staff leave or devices are lost
• Audit trails are incomplete or unavailable
• Scaling messaging across teams or departments becomes impractical

Notifyre's virtual SMS numbers and service is built specifically for business use, not personal messaging.
 

It supports SMS compliance through:

• Centralised SMS history across all users and numbers
• Opt‑out and unsubscribe management to ensure requests are honoured promptly
• Clear sender identification options, including virtual mobile numbers and Sender IDs

• Uses digits only (up to 11)
• Appears like a regular mobile number to the recipient
• Must provide proof of ownership of the mobile number used

Alphanumeric Sender ID

An Alphanumeric Sender ID combines letters and numbers (for example, Notifyre01).

• Up to 11 characters

• Displays a recognisable business identifier instead of a phone number
