Unregistered Branded SMS to Be Labelled ‘Unverified’

Why It Matters

Unverified tags can cause legitimate alerts to be dismissed, harming customer experience and brand reputation while strengthening scammers’ ability to impersonate trusted names.

Key Takeaways

• Unregistered SMS will show “Unverified” label from 1 July
• Labels may cause customers to ignore legitimate messages
• Registration required through approved telcos or messaging providers
• Thousands of Australian brands already registered, e.g., Coles, Australia Post
• Non‑compliance risks brand reputation and increased scam exposure

Pulse Analysis

The Australian Communications and Media Authority (ACMA) is tightening its anti‑scam toolkit by mandating that all branded SMS sender IDs be registered before 1 July 2024. Unregistered messages will automatically carry an “Unverified” tag and be grouped with known scam traffic, a move designed to make spoofed texts easier for consumers to spot. The policy follows a surge in SMS‑based phishing and credential‑theft attacks that have eroded confidence in mobile messaging. By forcing a clear label on unknown senders, ACMA hopes to restore a baseline of trust in text‑based communications.

Businesses that rely on appointment reminders, delivery updates, or two‑factor codes must now verify their sender IDs through an approved telco or messaging platform. ACMA has published a list of participating providers, and early adopters such as Coles, Australia Post, AAMI and the Australian Taxation Office have already completed the process. The registration step typically involves submitting proof of brand ownership and a short technical configuration, after which the “Unverified” flag is removed. Companies that delay risk having critical alerts hidden or deleted, which can damage customer experience and erode brand equity.

The Australian move mirrors similar sender‑ID verification schemes in the United Kingdom and the United States, where carriers already block or label unauthenticated texts. For multinational firms, aligning with ACMA’s timeline avoids fragmented compliance and protects global brand consistency. Experts advise treating the registration as a baseline security measure rather than a one‑off task, integrating it into broader mobile‑messaging governance. As consumers become more vigilant, verified SMS will likely become a competitive differentiator, rewarding brands that prioritize transparent, trusted communication channels.
