Doximity DocFax Is for Clinicians. OneFaxNow Is for Everyone.
No credential verification. No account. No subscription. HIPAA-compliant fax for $6.50 -- available to anyone.
Doximity DocFax is a free, HIPAA-compliant fax service -- but only for verified physicians, NPs, PAs, and pharmacists. If you are a medical office manager, billing specialist, medical assistant, nurse, or patient, you cannot use it. OneFaxNow fills that gap: anyone can send a HIPAA-compliant fax from any device, with an instant BAA and no credential verification required.
TL;DR: Choose Doximity DocFax if you are a verified clinician who faxes regularly and wants a free inbound fax number. Choose OneFaxNow if you need to send one HIPAA fax right now -- regardless of your role -- without an account or credential check. Doximity eligibility and limitations verified on their Help Center.

Frequently Asked Questions
Is Doximity Fax really free?
Yes, Doximity DocFax is free for verified clinicians (MDs, DOs, NPs, PAs, PharmDs, CRNAs, Podiatrists, Dentists, Medical Students). However, office staff, medical assistants, billing specialists, patients, and non-clinical personnel cannot use it at any price.
Can office staff or billing departments use Doximity Fax?
No. Doximity Fax requires a verified clinician account. Medical assistants, billing coders, office managers, and other non-clinical staff are not eligible. OneFaxNow requires no account or credential verification -- anyone can send a HIPAA-compliant fax.
Can patients fax medical records using Doximity?
No. Patients cannot create Doximity accounts or use DocFax. If you need to fax medical records, insurance forms, or prior authorizations to a provider, OneFaxNow lets you send a HIPAA-compliant fax from any device without an account.
What happens if I stop using my Doximity fax number?
Doximity reclaims your fax number if you do not send or receive at least one fax every 6 weeks. You will receive two email reminders, but the number may not be recoverable once reclaimed. OneFaxNow is pay-per-fax with no recurring obligations.
Is OneFaxNow HIPAA compliant like Doximity?

Does OneFaxNow provide an inbound fax number?
