Port Your eFax Number to Send FAX Mail
Leaving eFax but want to keep the fax number your contacts already have? Your eFax number can be ported to Send FAX Mail through the standard Local Number Portability process. Here's exactly what the transfer needs, how long it takes, and how to avoid the mistakes that stall an eFax port.
eFax numbers — local and toll-free — are carrier numbers, which means they move under the same Local Number Portability (LNP) rules the phone industry uses for any number. The transfer is a request to the carrier that currently holds your eFax number to release it to Send FAX Mail's carrier. Nothing about the number itself changes; only the service behind it does. The one rule that matters most with eFax: keep your subscription active until the port completes, because canceling first can release the number back into the pool and end the transfer.
A dedicated eFax number is a real carrier number, so it can move to Send FAX Mail through standard number portability — the checklist and steps below cover exactly how.
What you'll need to port your eFax number
- Your most recent eFax invoice or a bill showing the fax number and the account holder's name
- Your eFax account number (in your profile at account.efax.com or on a billing statement)
- The exact account-holder name and service address on file with eFax — the port matches these letter for letter
- Any port-out PIN or passcode eFax has set on the account (request it from eFax support if you don't see one)
- A signed Letter of Authorization (LOA) — Send FAX Mail provides this to sign during the request

- 5Once the carriers confirm the cutover, your eFax number rings into Send FAX Mail; only then cancel eFax
How long does the port take?
A local eFax number usually ports in roughly a week of business days once the paperwork clears. A toll-free eFax number is routed through RespOrg and typically takes about two to four weeks. Almost every delay traces back to a detail on the LOA that doesn't match eFax's records exactly, so double-check the account name before you submit.
Getting your details from eFax
eFax doesn't publish a self-serve port-out button — the account number lives in your online profile, but the port-out PIN (if one is set) usually has to be requested from eFax support. Ask them for the account number, the PIN or passcode, and the account-holder name and address exactly as billed. We can't read those values for you, so pull them from your own eFax account before you file the request.
Porting your eFax number — FAQ
You keep the same number. Porting transfers the existing eFax number to Send FAX Mail, so your published fax line stays identical and your contacts, letterheads, and directory listings need no changes.
No — do the opposite. Leave eFax active until the transfer finishes. Canceling early can send the number back to the carrier pool, after which it may no longer be portable.
Toll-free numbers are administered through a shared registry called RespOrg rather than a single local carrier, and that extra routing layer adds time. Budget two to four weeks for a toll-free eFax line versus about a week for a local one.
Your number keeps receiving on eFax right up until the moment it cuts over to Send FAX Mail, so there's no window where the line goes dark. Download any fax history you want to keep from eFax before you close the account.
