Does my school need to register an SMS Sender ID with the ACMA?
From 1 July 2026, the Australian Communications and Media Authority (ACMA) SMS Sender ID Register will protect schools and the community from scammers by preventing the use of branded text message sender IDs to impersonate known organisations.
A sender ID is the name shown at the top of SMS messages from businesses or organisations. It identifies the sender, such as ATO, AusPost, or myGov. For more information, visit the ACMA website.
Your school must register its SMS Sender ID with ACMA if it sends SMS messages under a Display Name instead of a mobile number.
Streetdata or BulkSMS: If your school uses Streetdata or BulkSMS as the SMS provider for TASS messages, contact the provider for guidance on registering your SMS Sender ID.
TASS SMS: If your school uses TASS SMS, you only need to register if an alphanumeric text ‘Display Name’ is entered in the ‘SMS Gateway’ program in TASS.web System Admin > Utilities > API Gateway Maintenance.
If the ‘Display Name’ field contains alphanumeric text (not blank or a mobile number), such as 'MySchoolName', register it with the ACMA SMS Sender ID Register by creating a TASS Support Ticket with the following details:
Sender ID/Display Name (3-11 Characters):
ABN Number:
Business Name:
Business Website URL:
Business Contact Number:
Business Email Address:
Business Addresss:
Authorised School Contact Person (First Name and Surname):
Upon receipt, TASS forwards this information to the TASS SMS provider (SMSGlobal) for transmission to ACMA.
It is your school's responsibility to ensure sender IDs are registered and compliant. Because the 'Display Name' field in TASS.web is customisable, schools must inform TASS of the data entered or any changes to this field.
If your school has multiple sender IDs (different names for campuses), you must register all variations.
If your school does not register its SMS Sender ID by the deadline, your branded sender name may be flagged as untrusted by telcos or blocked from sending SMS messages. This could affect your ability to send important notifications. For compliance and enforcement details, refer to ACMA's official guidance.
