These errors prevent submission entirely and cannot be fixed by editing the data.
Error Message
Cause
What to Do
Must exactly match the Sender ID on this row in your downloaded working file. Do not replace it with a different Sender ID (even another one for the same account).
You changed the sender ID in the template
Download a fresh working file — do not modify the sender ID column
Sender ID is already registered and cannot be re-submitted
This sender ID has already been submitted or approved
No action needed — it's already in progress or complete
Sender ID appears more than once in the uploaded file
Same sender ID listed on multiple rows
Remove duplicate rows — each sender ID should appear only once
Business Match Errors
After format checks pass, we verify the sender ID matches the business details.
Error Message
Cause
How to Fix
Sender ID does not sufficiently match the registered business name
Sender ID doesn't align with the business name, domain, or trademark
Ensure the sender ID relates to the customer's registered business name, trading name, domain, or trademark
We could not finish the check for this sender ID. Try again.
Temporary system issue
Re-upload your file to retry validation
Tip: The sender ID should be recognizable as belonging to the business - for example, an abbreviation of the business name, the trading name, or a match to their website domain.
Tips for Successful Uploads
Don't modify the Sender ID column — Download the working file and only fill in the empty columns
Remove extra spaces — Many errors are caused by accidental spaces at the start or end of values
Use the correct formats:
ABN: 11 digits, no spaces (e.g., 53004085616)
Postcode: 4 digits (e.g., 3000)
Website: Full URL with https:// (e.g., https://www.example.com.au)
Phone: Digits with optional formatting (e.g., +61 412 345 678)
Check authorized contact details carefully — ACMA will contact this person to approve the registration
