Port Your Fax.com Number to Send FAX Mail
Leaving Fax.com but want to keep your fax number? It can be ported to Send FAX Mail through the standard portability process. This page lists what Fax.com needs to release the number, the realistic timeline, and how to gather your account details before filing.
The fax number Fax.com assigned you is a carrier number, so it isn't tied to their platform — it can be moved. To port it, Send FAX Mail files a request against the carrier serving your Fax.com line, and Fax.com releases the number once ownership is validated. The single rule that protects your port is timing: keep your Fax.com account paid and active until the number has moved, because a canceled account can lose the number entirely.
A dedicated Fax.com 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 Fax.com number
- A recent Fax.com invoice showing the number and the account holder's name
- Your Fax.com account number from your billing statements or account page
- The account-holder name and address exactly as Fax.com has them recorded
- A port passcode if Fax.com applies one — confirm with Fax.com support
- The signed Letter of Authorization provided by Send FAX Mail

How long does the port take?
A local Fax.com number generally ports in about a week to two weeks of business days once the paperwork validates. If your line is toll-free, plan for two to four weeks through the toll-free registry. The reliable way to avoid a delay is to make the LOA match Fax.com's billing record exactly.
Getting your details from Fax.com
Your Fax.com account number appears on billing statements and in your online account; a port-out passcode, if one is set, comes from Fax.com support. Gather the account number and the billing name and address, and confirm your line type. These live in your own Fax.com account, so retrieve them there rather than relying on an assumed value.
Porting your Fax.com number — FAQ
The number is a portable carrier number, so yes — you can take it with you. Porting transfers it to Send FAX Mail while the number itself stays exactly the same.
About a week to two weeks for a local number, and two to four weeks for a toll-free one. The difference comes down to the toll-free registry adding routing steps a local number skips.
A detail that doesn't match — usually the account name, address, or account number differing between the LOA and Fax.com's records. Fixing the mismatched field and resubmitting resolves it.
Last. Keep Fax.com active until Send FAX Mail confirms the number is live, then cancel. Canceling first risks losing the number before the port can complete.
