FaxDx

Misdirected fax transmissions are one of the most common HIPAA breach types. FaxDx exists to prevent them. Search any provider by NPI number, name, or practice address. FaxDx cross-references the NPPES registry against six additional signals — received fax history, payer directories, co-located providers, health system websites, and more — to surface the most likely current fax number. Then it dials the number and confirms the line is active as a working fax machine. Every verification generates a timestamped audit record: the provider NPI, the number verified, the sources checked, probe result, and the identity of the user who ran the check. If OCR ever asks what you did before sending, you have a documented answer. No PHI is ever entered or stored. Free for individual coordinators. Pro and Department plans for teams that need full audit history and bulk verification.

How it works

Faxify

Faxify is an online fax service from Const Agility, LLC that lets businesses and professionals send and receive faxes across the United States and Canada without a fax machine, phone line or extra hardware. It runs on iPhone, iPad and Android, and in any web browser on a Mac or Windows PC at app.faxify.com. Every account includes 5 free pages each month for sending, with no credit card and no trial. To send a single fax without a subscription, a one-time Fax Pass covers one fax of up to 25 pages for $2.99, or up to 100 pages for $4.99. Paid plans start at $7.99 a month (or $69.99 a year), remove ads, raise the page allowance and include a dedicated fax number for receiving faxes. Faxify accepts PDF, Word and common image files, and has built-in tools to scan paper documents with a phone camera, edit PDFs, sign documents and add a cover page. Documents are protected with 256-bit SSL encryption in transit. For AI workflows, Faxify runs a hosted MCP (Model Context Protocol) server at mcp.faxify.com with 18 tools, so assistants such as Claude, ChatGPT and Cursor can send and track faxes. It's available on every plan.

Fax It Once

FaxItOnce is a pay-per-fax service for people who need to send one fax, not sign up for a monthly plan. Upload a PDF, enter the fax number, pay $2.75, and the fax goes out. Up to 45 pages per fax, one flat price, no subscription, no per-page charges, no cover-page advertising. It works from any web browser on a computer, tablet, or phone, with nothing to install. Several PDFs can be uploaded together and sent as one fax. When the receiving machine has accepted every page, a delivery confirmation arrives by email. If a fax cannot be delivered, there is no charge. It is used most for forms that still must be faxed: IRS forms such as SS-4, 2553 and 2848, insurance and benefits paperwork, medical records requests, and court filings. Guides on the site list the right IRS fax number by form and state. Documents are encrypted in transit, not shared for marketing, and deleted automatically after transmission. Sends to the US and 38 other countries. PDF only. Operated by GovBotics.
