A Letter of Authority (LOA) authorizes AVOXI to port your existing phone number away from your current carrier. Most ports require this before AVOXI can begin the transfer — check for a country-specific LOA page first, since those override this general version.
Why This Is Required
Your current (losing) carrier needs written authorization from someone with authority on that account before it will release the number for porting. This protects against unauthorized number transfers and is a standard requirement across most porting carriers.
What You Need to Provide

Must be completed by an authorized contact on your current (losing) carrier's account — this is critical to avoid delays in the porting process

How to Submit It
Download the AVOXI Letter of Authority.docx and have an authorized contact on your losing carrier's account complete it.
Upload the completed form directly within your AVOXI platform.
Once uploaded, the document is automatically submitted to AVOXI's team for review — status updates in real time within the platform.
If a document is rejected, you'll receive a notification with specific feedback so you can correct and resubmit it.
Uploaded documents are saved in your document library, so you can reuse them for future requests without re-uploading.
For a detailed, step-by-step walkthrough of uploading documents, see the Number Management Guide.
Note: The number will not work and remains blocked until the documentation is received and registered with the local provider.
