Overview
When porting a fax number to Evo Voice—especially for configuring it as an eFax endpoint—specific documentation is required to ensure the request is accepted by the losing carrier and that Evo can initiate the port without delay.
Porting Requirements for eFax Numbers
To successfully initiate the port of a number (such as 925-459-8445) into Evo Voice for eFax setup, the following are typically required:
✅ 1. Signed Letter of Authorization (LOA)
-
Must be fully completed and signed by the authorized account holder.
-
Should clearly list the number(s) to be ported.
-
Valid for 30–90 days depending on carrier.
✅ 2. Current CSR or Recent Phone Bill from the Losing Carrier
-
The Customer Service Record (CSR) is preferred as it ensures address and account details match exactly.
-
If a CSR is unavailable, a recent phone bill (dated within the last 30 days) showing the account number, service address, and number ownership can be used.
Additional Notes
-
For Comcast numbers, the CSR or phone bill must clearly show the fax number listed under the account.
-
The billing name and service address in the LOA must match what's shown in the CSR or bill.
-
Evo’s porting team will review the documents and notify you if further clarification or documentation is needed.
Next Steps
Once you have the signed LOA and CSR or bill, submit them to the Evo porting team (via the porting request form or support channel).
The team will:
-
Validate the documents
-
Initiate the port with the underlying carrier
-
Notify you of any rejections or expected activation timeline
