Nextiva vFAX is one of the most affordable standalone online fax services — starting at $7.95/month — but it has real gaps: no mobile app, no international faxing, and standard plans aren't HIPAA compliant. Here's the full breakdown before you sign up.
Frequently Asked Questions
How much does Nextiva fax cost?
Nextiva vFAX starts at $7.95/month billed annually (or $9.95/month month-to-month) for 500 combined pages per month. The Professional plan runs $13.95/month annually for 1,000 pages, and the Max plan is $29.95/month annually for 3,000 pages. Overage is $0.03 per page on all plans.
Is Nextiva fax HIPAA compliant?
Standard Nextiva vFAX plans are NOT HIPAA compliant. Nextiva explicitly states this — no Business Associate Agreement (BAA) is offered on standard vFAX plans. A separate HIPAA-compliant fax tier exists at custom pricing, but most small-business customers won't qualify for it. Healthcare organizations should look at dedicated HIPAA-compliant fax services like [mFax Business](/blog/is-faxing-hipaa-compliant/).
Does Nextiva fax have a mobile app?
No. Nextiva vFAX does not have a dedicated iOS or Android app. Mobile faxing is done through the web portal in a mobile browser, or via email-to-fax (sending a fax by emailing to 1[10-digit-fax-number]@nextivafax.com). This is a notable gap compared to competitors.
Can I use my existing fax number with Nextiva?
Yes. Nextiva supports number porting — you can bring your existing fax number to their platform. The porting process typically takes 2–4 weeks. Note that a ported number can be used as either fax or voice, but not both simultaneously.
Does Nextiva offer fax for international numbers?
No. Nextiva vFAX only supports faxing within the US, Canada, and Puerto Rico. If you need to send faxes internationally, you'll need a different provider — see our [international faxing guide](/blog/complete-guide-international-faxing/).
How do I log into the Nextiva fax portal?
Log in to the Nextiva fax portal (branded FAXAGENT) at fax.nextiva.com/xauth. If you signed up under the vFAX brand, the equivalent login is vfax.nextiva.com/xauth, and the legacy portal.nextivafax.com still works too. Your fax-portal login is separate from your Nextiva billing/account login.
How do I cancel Nextiva vFAX?
Send a written cancellation request to service@nextiva.com from your account email (include your account number and the last four digits of the card on file), or call 1-800-285-7995. Most plans require about 30 days' notice before the renewal date, and you should receive email confirmation within 24–48 hours. Back up your faxes first, since stored data is deleted when the account closes.
What is the Nextiva fax customer service number?
Nextiva's general support and cancellation line is 1-800-285-7995, which is available 24/7. (Note that 1-800-799-0600 is the separate sales line, also used for HIPAA-tier inquiries.)
What is the Nextiva Fax Bridge?
The Nextiva Fax Bridge is an analog telephone adapter (ATA) that lets a legacy fax machine run over Nextiva's network. It converts your fax machine's analog signals to the T.38 digital fax protocol so you can keep using existing hardware without a phone line.
