How Australian SMS works

How business SMS works in Australia

Australia allows brand-name (alphanumeric) sender IDs such as "ACME", which customers trust more than a random number. Since 1 July 2026, those sender IDs must be on the ACMA SMS Sender ID Register. Messages from an unregistered brand sender ID are shown as "Unverified" instead of your brand name, and are far more likely to be ignored.

You can also send from a phone number, which is not covered by the register and suits two-way messages. Either way, commercial messages must follow the Spam Act 2003: get consent, identify your business and include a working unsubscribe option. We explain the sender options and the register before your first campaign.

Frequently asked questions

Can I send SMS to Australia from India?

Yes. Bulk SMS India sends SMS to Australian mobile numbers for businesses in India and abroad, using a registered alphanumeric sender ID or a phone number.

What is the ACMA SMS Sender ID Register?

It is Australia's national register of brand-name (alphanumeric) sender IDs, run by the ACMA. Since 1 July 2026, messages from brand sender IDs that are not registered are shown as "Unverified" instead of the brand name.

Do I need to register if I send from a phone number?

No. The register covers alphanumeric sender IDs. Messages sent from phone numbers are not covered, though Spam Act rules still apply.

Can customers reply to my SMS in Australia?

Not to an alphanumeric sender ID, which is one-way. If you need replies, send from a mobile or virtual number.

What does the Spam Act require for SMS?

Commercial messages need the recipient's consent, must identify your business and must include a working unsubscribe option.
