Receiving faxes

What it takes to receive, why it isn’t free, and why CaptainFax sticks to sending.

Updated on:

Receiving a fax requires a number that belongs to you. Whenever someone calls it, a fax machine or a server answers, interprets the tones, reassembles the pages and, with an online service, emails you a PDF. Sending simply means calling another person’s number. Receiving means holding a line open in your name every hour of the day, and that line has a monthly cost. For this reason a free page is feasible on the sending side, whereas free incoming service is nearly nonexistent.

Three parts of the chain

A machine on a desk or a web service, the pieces are the same.

  1. 1

    A number that’s yours

    People dial it to reach you. It may be a local number or a toll-free one. Without an assigned number, a fax has no place to arrive.

  2. 2

    Decoding the tones

    The audio gets turned back into an image. A cloud service handles this on its own servers, so you don’t need a machine or a phone jack.

  3. 3

    Delivery to you

    The finished pages show up as a PDF in your inbox or in a web portal. This setup is usually called fax-to-email.

Why there’s a price

Phone numbers are handed out by regulators to carriers, which lease them to customers. Yours is billed every month whether it gets a hundred faxes or none. Receiving is therefore a subscription, not a pay-per-use service.

An outgoing fax borrows shared capacity for a minute or two, so a per-send price, or no price at all for a single page, is workable. If you see free incoming faxes advertised, the catch is usually a brief trial, a number shared by lots of users without any guarantee, or a service funded by advertising.

Your options

  • Sign up for fax-to-email

    You rent a number, and each incoming fax shows up in your inbox as a PDF. It suits anyone who gets faxes often, and it is the only option once you have given up your landline.

  • Keep the machine you have

    Reasonable if it works. Check how your line is delivered, though. Lines moved to voice over IP handle fax poorly, and copper networks are being phased out.

  • Ask for a different channel

    Plenty of senders will gladly use email, mail or a secure upload portal if you ask. A short phone call might save you a subscription.

Where incoming faxes are kept

Fax-to-email routes each document through the provider’s servers and then leaves it in your mailbox until you remove it. A lab result, a lease or a court filing is only as safe as your email account, so if these papers hold personal details, secure that account first.

CaptainFax is send-only

CaptainFax delivers your files to landline fax machines in seven countries, with no account and optional PDF receipts. We don’t issue fax numbers and we don’t take incoming faxes. Better you learn that here than after signing up somewhere else.

Receiving: your questions

Is free fax reception a thing?
Seldom, and not for long. Holding a number costs the provider money every month. Offers billed as free are typically a trial, a shared number or an ad-funded service.
Can I receive faxes without a landline?
Yes. Under fax-to-email your number sits on the provider’s system, and every fax is passed on to you as a PDF. There’s no equipment to set up and no phone jack required.
Does it work on a smartphone?
Only indirectly. You open the emailed PDF in the mail app on your phone. A cell number itself can’t receive a fax, since mobile networks don’t carry that sort of call.
Can I receive faxes anonymously?
No. Every number belongs to a holder the carrier has verified. That is a telecom regulation, not a company policy.
Will CaptainFax give me a fax number?
No. CaptainFax only sends. We don’t assign numbers and we don’t receive faxes for anyone.
