PostFax: What People Actually Mean (and How to Fax Today)

If you typed "postfax" into Google, you probably landed on this page for one of two reasons. Either you're looking for a company or product actually called PostFax, or you're really trying to figure out if you can fax something at the post office and typed it as one word. Both searches are more common than you'd think, and the honest answer involves a little bit of untangling before we get you to a working solution.

What Does "PostFax" Actually Mean?

Here's the surprising part: there isn't a major online fax service called PostFax. If you search for it directly, most of what turns up is an office supply brand that sells plastic binder dividers and index tabs, a completely unrelated product line sold through retailers like OfficeWorld and eBay. It has nothing to do with sending or receiving a fax.

So where does the confusion come from? A few places:

• Some people are mentally combining "post office" and "fax" into a single search term, since they assume USPS handles fax the way it handles mail.
• Others misremember the name of a fax app or service they saw once and typed the closest thing that came to mind.
• A few are just typing shorthand for "how do I post a fax," meaning send one.

Whatever brought you here, the underlying need is almost always the same: you have a document, you need it on the other end of a fax line today, and you don't own a fax machine. Let's solve that.

Can You Actually Fax at the Post Office?

This is the question worth answering directly, because it trips up a lot of people. USPS does not offer fax services at the vast majority of its 31,000+ locations across the United States. It's not a matter of some branches having it and others not, at least not officially.

Part of the confusion comes from private postal stores that look similar to an official post office but aren't. Many private postal retailers, think The UPS Store or your local neighborhood shipping center, do still have fax machines available for public use. People often lump these places together, but it's a critical distinction that can save you a wasted trip. A store with "postal" in its name, like PostalAnnex or Postal Connections, is a private franchise, not a USPS branch, and it sets its own fax pricing.

If you do go the in-store route, here's what it typically costs in 2026:

• Staples and Office Depot: around $1.79 for the first local page
• FedEx Office: about $1.89 for the first local page, $1.59 per additional page
• The UPS Store: roughly $2 to $3 for the first page
• International faxes from any of these: often $5.99 or more per page

For a domestic fax, in-store prices generally land between roughly $0.50 per page at a budget public library and about $3.00 for a first page at The UPS Store, with international pages running far higher, up to about $7.99. That means a routine 10-page fax to a local insurance office can run you $16 to $20 once you factor in the drive, and a multi-page international fax can easily clear $50.

The Faster, Cheaper Way to Send a Fax

If what you actually need is to get a document faxed without hunting down a working machine, standing in line, or paying inflated per-page retail rates, an online fax service solves the whole problem from your phone or laptop.

With SendFax.me, the process looks like this:

1. Go to the homepage and upload your document as a PDF or an image, no scanning trip required.
2. Type in the recipient's fax number. SendFax.me sends to 150+ countries, so this works whether you're faxing a local clinic or an office overseas.
3. Add a cover page if you want one, or fill and sign the document right in the browser before you send it.
4. Send immediately, or schedule it for later if the recipient's office only accepts faxes during business hours.
5. Get a delivery confirmation with a transmission report so you have proof it actually went through, something none of the in-store options reliably offer.

There's no subscription to commit to. It's pay-as-you-go per page, and your first fax is free, so you can test the whole flow before spending anything. If you've never sent a fax online before, the step-by-step first fax guide walks through it in more detail, and the pricing breakdown shows exactly what each page costs before you commit.

If you need to receive faxes regularly, not just send them, you can get a dedicated fax number tied to your account, so incoming faxes land in your inbox instead of a machine somewhere you're not standing. There's also email-to-fax support if you'd rather just attach a file to an email and send it that way; the email-to-fax help article covers the exact format to use.

When You're Faxing Regularly, Not Just Once

A one-off fax is one problem. Faxing as part of a workflow, like a medical practice sending prior authorizations, a law firm serving documents, or a logistics company confirming loads, is a different problem entirely, and per-page retail pricing or manual uploads don't scale.

For that, the SendFax.me fax API lets developers and companies send a fax with a single POST request, get real-time delivery status through webhooks instead of refreshing a dashboard, and generate API keys directly from the account dashboard. Volume credit packs start around 4 cents per US page, which is a fraction of what a single walk-in fax at a retail counter costs. If your product needs to plug fax sending into an EHR, a pharmacy system, or a SaaS tool, the documentation at sendfax.me/developers covers authentication, endpoints, and webhook setup in detail.

A Quick Recap

There's no legitimate service called PostFax, and USPS itself doesn't offer public fax service at its branches, despite how often people assume it should. If you're faxing occasionally, an online service saves you the drive and the per-page retail markup. If you're faxing at volume as part of a business process, the API route saves your team from touching a fax machine at all.

One more tip while you're setting things up: if your business also handles customer questions or booking requests outside business hours, a tool like Agentika, a 24/7 AI assistant widget for service businesses, can answer visitors and capture bookings while you're dealing with paperwork like this. And if you're a developer who likes tracking what new tools are launching in this space, ReHunt sends a personalized Product Hunt digest to your inbox on a schedule you set, which is a handy way to spot the next fax or workflow tool worth trying before everyone else does.

Either way, the fastest fix for "I need to send a fax and I don't have a machine" is still the same: skip the post office, skip the store line, and send it from wherever you already are.
