What to prepare before you start
- A current business registration extract or incorporation document showing your business name, registration number, registered address, and listed officers, directors, or authorised contacts.
- Your exact business registration number, such as ABN or ACN, exactly as it appears on your official business record.
- A physical registered business address. Do not use a PO Box.
- A working public website or landing page that clearly represents your business, brand, or Sender ID.
- Evidence that your requested Sender ID belongs to, or is clearly connected to, your business, trading name, brand, trademark, or domain.
- Government ID for a listed officer or director, or government ID for an authorised representative plus a signed Letter of Authorization from a listed officer or director.
Choose the right entity type
The registration form may use generic international entity types rather than Australian labels. Choose the option that best matches your official registration record.| Australian entity type | Closest form option |
|---|---|
| Proprietary Limited / Pty Ltd company | Private Corporation is usually the closest match. |
| Sole trader | Sole Proprietorship. Use the registered business details exactly as shown on official records. |
| Partnership | Partnership. Use the partnership details exactly as shown on official records. |
| Public company | Public Corporation. Use this only if the business is actually a public company. |
| Co-operative | Co-operative. Use this only if it matches the legal structure shown on official records. |
| Government entity | Government. Use this only if the entity is a government organisation. |
| Non-profit, incorporated association, or charity | Non-profit Corporation may be the closest option if it best matches the legal structure. |
Choose your Sender ID text
Your Sender ID is the SMS “from” text your clients see.- Use 2-11 characters, up to the maximum 11 characters allowed for Branded SMS Sender IDs.
- It may contain a-z, A-Z and 0-9 only. Symbols and spaces are not supported.
- Include at least one letter.
- It must not be misleading or unrelated to the business.
- Choose a Sender ID that clearly matches your registered business name, registered trading name, brand, trademark, or domain.
- Avoid generic Sender IDs that could apply to many businesses, such as only describing a trade or service.
Prepare Sender ID proof
- If the Sender ID does not exactly match your legal business name, prepare evidence showing the connection.
- Useful proof may include a company extract, registered business name, matching .au domain, Australian trademark, international trademark, or another form of authorisation.
Check website and domain evidence
- Use a working public website or landing page that clearly shows the business, brand, or Sender ID.
- Social media pages, login-required pages, under-construction pages, or unrelated websites may not be accepted.
- If you use a domain as evidence, make sure the domain or website clearly connects to the registered business or brand.
Prepare authorised representative details
- The simplest path is usually for a listed officer or director on the business extract to provide their government ID.
- If the person completing the application is not listed on the business extract, upload a signed Letter of Authorization from a listed officer or director.
- Enter the authorised representative’s legal name exactly as it appears on their government ID.
- Check spelling, middle names, hyphens, and name order before submitting.
- Upload a clear, uncropped copy of the government ID.
- If the ID has a front and back, include both sides.
- Use a business email address for the authorised representative where possible.
