FAQs
What is the SMS Sender ID Register and why does it matter?
The SMS Sender ID Register is a new mandatory requirement introduced by the Australian Communications and Media Authority (ACMA) to combat SMS impersonation scams. From 15 December 2025, all businesses must register their sender IDs to avoid messages being marked as “Likely SCAM” or blocked by telcos. Kudosity helps you stay compliant with minimal disruption.
Does my business need to register a sender ID to continue sending SMS in Australia?
Yes. If your business sends SMS with alphanumeric sender IDs (e.g., "MyBrand"), you are required to register each ID. Failure to do so will result in messages being over-stamped or rejected. Kudosity provides full support for sender ID registration, validation, and compliance with ACMA’s standard.
How does Kudosity ensure compliance with Australian data and privacy laws?
Kudosity operates fully under Australian jurisdiction, with all data hosted onshore. We are compliant with the Australian Privacy Act 1988 and all Australian Privacy Principles (APPs). Additionally, our operations are certified to ISO 27001 and SOC 2 Type 2, ensuring strict data protection protocols.
Is Kudosity an Australian-owned company?
Absolutely. Kudosity is 100% Australian-owned and managed, with local teams providing end-to-end service, including compliance, delivery, support, and infrastructure. This gives us unmatched agility and understanding when helping businesses meet Australian messaging regulations.
What happens if my SMS sender ID isn’t registered by the ACMA deadline?
If your sender ID isn’t registered by 15 December 2025, telcos will over-stamp it with ‘Likely SCAM’, or block it altogether resulting in failed or misbranded message delivery. Kudosity ensures timely registration and telco approvals so your customer communications remain uninterrupted.
Can Kudosity support us if we use CRMs or SaaS platforms to send SMS?
Yes. Whether you use a CRM, SaaS platform, or integrate via API, we support direct and indirect messaging workflows. Kudosity’s platform and telco partnerships ensure your electronic messaging service providers (EMSPs) remain compliant under the ACMA framework.
Does Kudosity offer 24/7 support for compliance and delivery issues?
Yes. We provide round-the-clock support from our Australian-based customer success team. Whether you're onboarding, registering sender IDs, or managing urgent delivery issues, you’ll always speak to someone who understands the Australian compliance landscape.
