Why do I need to complete the forms again?
Documentation submitted through the previous registration process cannot be transferred to our new approved provider pathway, so fresh documentation is required.
Compliance Update
SMS Sender ID registration
From 1 July 2026, businesses sending SMS from a branded Sender ID must register it under the Australian SMS Sender ID Register. Here's what you need to do.
Why this is changing
From 1 July 2026, businesses sending SMS using a branded Sender ID (your business or organisation name) must register that Sender ID under the Australian SMS Sender ID Register.
Unregistered Sender IDs may be displayed to recipients as "Unverified", which reduces customer trust and can affect message delivery.
Action required
What to submit
- Signed Letter of Authorisation (LOA)
- Completed Sender ID Information Form
- Sample ASIC Current Company extract
Return your completed documents to squish@ish.com.au.

General Sender ID formatting rules
When choosing your Sender ID, please ensure it meets the standard formatting requirements used for SMS Sender IDs:
- Must be between 2 and 11 characters long.
- Must contain at least one alphabetic character (it cannot consist only of numbers).
- Cannot begin or end with spaces or underscores.
If your requested Sender ID does not meet these requirements, it may be rejected during the registration process.
During the transition
While your registration is being processed:
- SMS messages may be sent from a temporary Australian mobile number or another approved interim sender.
- We are registering ishOnCourse as a platform Sender ID.
- Once approved, ishOnCourse may be used as the interim default Sender ID until your own branded Sender ID is approved.
- While using an interim sender, please identify your organisation within the SMS message body so recipients know who the message is from.
Frequently asked questions
What happens if I don't register my own Sender ID?
SMS messages will continue to be sent using the available default sender option (such as the ishOnCourse Sender ID once available), rather than your own business name.
Compliance reminder
This process relates only to Sender ID registration. Businesses remain responsible for complying with Australian SMS requirements, including consent, message content and unsubscribe obligations.
