Faxio is an online fax service operated by Bear Labs LLC in Lewis Center, OH. You upload a document in a browser, we transmit it over the telephone network to the recipient's fax machine, and you get a delivery confirmation. On the web it costs $2.99 per fax with no subscription.

Why these guides exist

Almost everyone who needs to send a fax needs to do it once, under a deadline, for an organisation that will not accept email. They search for a fax number and land on pages written to sell a subscription rather than to answer the question.

A lot of those pages are wrong in ways that cost people weeks. They publish a “USCIS fax number” when USCIS does not have one. They list an SSA number when each of 1,200 Social Security offices runs its own line. They skip the fact that the IRS rejects a large share of faxed forms over signatures.

These guides try to be the page we would want to find: the right number from the official source, what actually gets rejected, and an honest answer about when you should not fax at all.

How the information is verified

  • Agency fax numbers come from the agency — IRS form instructions, VA.gov, USCIS policy manuals — never from another fax company's blog post.
  • Every page carrying numbers or procedures shows the date it was last checked, because agencies change fax numbers without notice.
  • Where a competitor is cheaper or better for your situation, the guides say so. Our price comparison names services that beat us on long documents.
  • Where fax is the wrong channel, the guides say that too, even when it costs us the sale.
