⚠ Australia — Sender ID Register · Mandatory from 1 July 2026

Sender ID — Send SMS From Your Brand Name

Since 1 July 2026, Australian carriers mark unregistered Sender IDs as UNVERIFIED — or block them entirely. MessageWorks registers your brand name directly through ACMA, so your messages arrive trusted, verified, and recognised.

  • Your business name as the SMS sender — not a random number
  • Registered via Australia's official Sender ID Register (ACMA)
  • Add Engagement Links so recipients can still reply and opt out
  • Full opt-out compliance even without a replyable number
  • MessageWorks manages the registration process end-to-end

If your business already sends from a brand name (e.g. "MyBusiness" instead of a phone number), you must register that Sender ID with ACMA or your messages will show as UNVERIFIED — or be blocked — on recipients' devices from 1 July 2026 onwards.

Everything included with Sender ID

Registration is just the start. MessageWorks makes sure your Sender ID messages work as effectively as number-based campaigns.

Verified brand name as sender

Your business name — not a random number — appears on every message. Recipients see exactly who it's from before they open it.

Instant consumer trust

Since 1 July 2026, registered Sender IDs display a 'Verified' indicator on compatible devices. Unregistered names show 'UNVERIFIED' — or are blocked entirely by carriers.

Two-way capability without a number

Add an Engagement Link to any Sender ID message so recipients can reply or opt out with one tap. Responses land in your MessageWorks Inbox matched to their contact record — full conversation history, no replyable number required.

Compliant opt-out management

Engagement Links handle opt-outs automatically even when sending from a Sender ID. No STOP keyword, no manual processing — fully compliant with Australian spam obligations.

MessageWorks arranges registration

We manage your Sender ID registration with ACMA directly. No dealing with bureaucracy — tell us your brand name and we handle the paperwork.

Works alongside a dedicated number

Use your Sender ID for outbound campaigns and your Dedicated Number for inbound conversations. Both flow into the same shared team inbox.

Two-way messaging — even with a Sender ID

A common concern with Sender IDs is losing the ability to receive replies. MessageWorks solves this with Engagement Links — a personalised, trackable link added to every outbound message.

  • Recipient taps the link → a reply form opens in their browser
  • Their message lands in your MessageWorks Inbox, matched to their contact record
  • Opt-Out Links handle unsubscribes with one tap — fully SPAM Act compliant
  • No app, no login — works on any smartphone
