+## Guidance for Australia sender ID registration
+
+The documentation and identity requirements on the registration form are required to satisfy ACMA's sender ID verification process. The following guidance addresses common questions about these requirements.
+
+### When is a Letter of Authorization (LOA) required?
+
+An LOA is _only_ required when the authorized representative listed on the registration form does **not** appear as a contact on the company's official business registry extract (ABN extract). If the authorized representative matches a contact already listed on the ABN extract, no LOA is needed.
+
+###### Important
+
+**Common reason for denial:** The most common reason registrations are denied is that the person listed as the authorized representative cannot be verified against the company's business registry. To avoid this:
+
+  * Ensure the authorized representative is listed as a Director, Officer, or authorized contact on your official ABN extract.
+
+  * If they are **not** listed, you must provide a signed Letter of Authorization from a listed Director or Officer authorizing that person to act on behalf of the company.
+
+
+
+
+### What to submit as company registration documentation
+
+For most companies, an ASIC extract (for Australian companies) or your country's equivalent business registration document is sufficient.
+
+**For Australian government entities** that are not ASIC-registered, follow these steps to obtain your ABR documentation:
+
+  1. Navigate to the [Australian Business Register](https://abr.gov.au).
+
+  2. Under **Online Services** , select **Update your ABN details**.
+
+  3. Log in using your myID app credentials.
+
+  4. Select **Update ABN record** to view non-public ABR information.
+
+  5. Choose the **Contacts** tab.
+
+  6. Take a screenshot of the information in that tab. This shows the authorized contacts for your ABN.
+
+  7. Submit this screenshot as the **Company registration documentation** attachment on the registration form.
+
+
+
+
+This screenshot serves as proof that the authorized representative is listed on the business registry. If the authorized representative appears in the **Contacts** tab, no separate LOA is needed.
+
+### Processing times
+
+Typical estimated completion time is 2 weeks from successful submission. Processing times may vary during high-volume periods, particularly as the ACMA SMS Sender ID Register enforcement date (July 1, 2026) approaches.
