Can I send a fax to a US number completely for free?

Yes. FaxZero and GotFreeFax both let you send up to 3 pages to any US fax number without creating an account or entering payment info. You only need an email address to receive the delivery confirmation.

Do free fax services require a credit card?

No-signup services like FaxZero and GotFreeFax require zero payment details — just an email. Account-based free tiers like Fax.Plus also require no credit card for their 10 free pages. Only trial-based services like eFax require a card.

How many pages can I fax for free to the USA?

It depends on the service. No-signup services cap at 3 pages per fax (up to 5 faxes per day on FaxZero). Account-based tiers give 5–10 pages as a one-time credit. For larger documents, a [pay-per-fax service](/blog/pay-as-you-go-fax-top-10-one-time-fax/) is often cheaper than you'd expect.

Will the recipient know I used a free fax service?

On FaxZero and SendItFax, yes — they add a branded cover page with their logo. GotFreeFax is the exception: it sends a clean, unbranded cover page on the free tier.

Are free fax services safe for medical or legal documents?

Most are not HIPAA compliant. For healthcare documents, use iFax (signs a free BAA) or consider [mFax Business](https://mfax.to/business/) which is designed for HIPAA-covered workflows.
