To port a United Kingdom number to AVOXI, our supplier requires a completed Letter of Authority (LOA).
Why This Is Required
The UK carrier requires a signed, current LOA — tied to a UK service address and a single losing carrier account — before it will release a number for porting.
What You Need to Provide
-

- Document must be on company letterhead
- Document must include a signature
- Document must include a recent date
- Document must provide a service address within the United Kingdom
- Document must list the United Kingdom phone number(s) to be ported
- Document must contain only one Losing Service Provider (LSP) account number per form
Important: if you have multiple numbers to port from multiple losing service provider accounts, you must split them across separate LOAs — one LSP account number per port form.
