usfax.com vs eFax
The eFax Alternative for Business

For many US businesses, yes. usfax.com publishes its prices openly — $2.99/fax pay-as-you-go, $19/mo Solo (300 pages), $29/mo Practice (800 pages, 5 users), and $59/mo Multi-site (unlimited pages, 10 users, API) — with no per-page overage and a free HIPAA BAA coming to all three (signed in Settings). eFax is widely used and its Business plan includes a BAA, but its pricing page does not show a flat monthly price and it meters overage at $0.10 or $0.07 per page. If you want published pricing, no overage and a self-serve set-up, usfax.com is a focused alternative.

As read from efax.com/pricing on September 21, 2026: eFax Personal includes 200 pages per month with $0.10 per page over; Business includes 500 pages per month to 51 countries with $0.07 per page over, 5 user licenses (about $10/mo each additional) and 1 fax number (about $5/mo each additional); Corporate is quote-based. The monthly prices themselves are not displayed on that page. usfax.com publishes every tier: Solo $19/mo, Practice $29/mo, Multi-site $59/mo, none with overage.

eFax includes a Business Associate Agreement on its Business plan and HITRUST certification on Corporate, which is a genuine strength for large organisations. usfax.com is bringing a free BAA to every paid plan from $19/month — you will sign it yourself in Settings → HIPAA BAA — with TLS 1.2 or higher in transit, AES-256 at rest and an audit log. Until that BAA is live and signed, a usfax.com account is not covered by a BAA and must not be used for protected health information. Neither service can make a practice compliant with HIPAA; that depends on your own program.

Yes. eFax's Business plan sends to 51 countries, its Corporate plan carries HITRUST certification, and it operates at a scale usfax.com does not. If you need international coverage or HITRUST, eFax is worth a look. usfax.com's edge is published pricing, no overage, users and numbers included rather than billed à la carte, and a self-serve HIPAA BAA on the way.

It depends on whose number it is. eFax's customer agreement treats numbers it assigned as its property, so those cannot be moved; a number you brought to eFax yourself can be ported back, and eFax's agreement requires written notice, a per-number fee, and an account in good standing, with the port filed within its reclaim window. Porting to usfax.com is free; a simple port takes about seven business days end to end. Run the free portability check first — it tells you which carrier holds the number.
