Fax at 8x8: Pricing, Process & Online Alternatives

By David Thompson · Published March 22, 2026 · Updated June 8, 2026 · 11 min read

Quick Verdict: 8x8 fax is a legitimate, HIPAA-compliant feature bundled into 8x8 Work — but it is not a standalone fax service. It lacks email-to-fax, mobile sending, and transparent pricing, and requires buying an entire UCaaS platform to use it. If your organization is already on 8x8 Work, fax is a reasonable add-on. If fax is your primary need, a dedicated service will cost less and do more.

8x8 is one of the most established names in cloud business communications, serving over 2 million users worldwide with a platform that combines voice calling, video meetings, team messaging, and contact center capabilities. Faxing is part of that platform — bundled into X Series plans as Internet Fax, available to any user with an X2 license or higher.

The framing matters: 8x8 is a UCaaS provider that happens to include fax, not a fax service. That distinction shapes everything — pricing, feature depth, the setup process, and whether 8x8 fax makes sense for your situation.

This guide explains exactly what 8x8 fax offers, how to set it up and use it, what it costs, and when a purpose-built fax service is the better choice.

What Is 8x8?

8x8, Inc. is a publicly traded cloud communications company (Nasdaq: EGHT) founded in 1987 and headquartered in Campbell, California. The company's core product is 8x8 Work — a unified communications platform that combines business phone, team messaging, and video meetings in a single app.

Beyond 8x8 Work, the company also offers:

• 8x8 Contact Center — an omnichannel customer experience platform (X6+ tiers)
• 8x8 CPaaS — developer APIs for voice, SMS, and fax-as-a-service
• Microsoft Teams integration — Direct Routing and Operator Connect

Fax is embedded into 8x8 Work as Internet Fax — a feature of the X Series plans, not a separate product. To use 8x8 fax, you subscribe to the full platform.

Does 8x8 Offer Fax?

Yes — 8x8 fax is included in all X2 and higher 8x8 Work plans. It supports:

• Internet Fax — cloud-based T.38 fax, the primary offering
• Analog Fax — connecting a physical fax machine via an ATA adapter
• Fax API — available to developers on CPaaS plans (separate from standard X Series)

Each licensed user gets a dedicated virtual fax number — a standard phone number assigned exclusively for fax, separate from their voice number. Faxes are sent from the 8x8 Work desktop app and received on both desktop and mobile.

8x8 Fax Pricing

8x8 has removed all pricing from its public website — quotes require contacting the sales team directly. Third-party sources and independent research indicate the following approximate ranges:

These figures represent list pricing. Actual quotes vary by organization size, contract length, and negotiated discounts. Internet Fax is not a paid add-on at any of these tiers — it is included.

Additional phone numbers (for extra dedicated fax lines) typically run $2–$10/month each.

The Cost Reality

At approximately $24–$32/user/month for the entry X2 plan, a single user needing fax capabilities will pay $288–$384 per year — for a service where fax is one of dozens of bundled features. A dedicated fax service like mFax Business starts at about $9/mo (billed annually) with fax as the core focus, HIPAA compliance, virtual fax numbers, and a signed BAA included. Instead of rigid fixed tiers, you build your own plan with a live calculator — choosing the exact seats and pages you need and paying only for what you use.

The math changes if your organization already needs the UCaaS platform. For a business that would have purchased 8x8 Work regardless, the included fax is effectively free.

How to Set Up 8x8 Fax

Setting up fax in 8x8 is an admin function managed through the 8x8 Admin Console. End users cannot self-provision fax numbers.

Admin Setup (Step-by-Step)

1. Log in to 8x8 Admin Console
2. Navigate to Home → Users and select the target user
3. In Fax notification settings, assign an available fax number from the inventory
4. Configure notification email address(es) for that user (inbound fax alerts)
5. Choose notification type: link only, attachment only, or both
6. Enable or disable notifications for sent faxes separately from received faxes
7. Save — the fax number is immediately active for that user

Changes sync automatically to the user's 8x8 Work desktop and web apps. The Admin Console and desktop app bidirectionally update settings.

Key constraint: Each user must have their own unique fax number. Shared fax numbers across multiple users are not supported. A fax line cannot simultaneously handle voice calls or SMS on the same number.

How to Send a Fax with 8x8

Sending a fax requires the 8x8 Work desktop application (Mac or Windows). The web app and mobile app do not support sending.

Sending Process

1. Open 8x8 Work for Desktop
2. Navigate to the Fax tab in the left sidebar
3. Click New Fax
4. Enter the recipient's fax number(s)
5. Fill in cover page fields (recipient name, optional note), or attach a custom cover page
6. Attach files — up to 5 files, total under 19 MB
7. Click Send
8. Receive an email confirmation of delivery success or failure (if notifications are enabled)

Supported File Types

8x8 fax accepts a broad range of file formats: PDF, DOCX, DOC, HTML, TXT, XLSX, XLS, CSV, PPT, JPG, PNG, TIF/TIFF, BMP, GIF, PSD, and most common image formats.

Fax Limits

How to Receive a Fax with 8x8

Incoming faxes appear in the Fax list within 8x8 Work — accessible on both desktop and mobile apps. Users receive an email notification when a fax arrives, with the fax delivered as a link, an attachment, or both depending on notification settings.

The 8x8 Work mobile app fully supports receiving, viewing, and managing faxes. What it does not support is sending — fax sending is desktop-only.

8x8 Fax: Full Feature Overview

What 8x8 Fax Does Not Support

Several features that are standard in dedicated fax services are absent from 8x8:

• Email-to-fax — cannot send a fax by emailing a fax number. Most dedicated services (fax to email guide) support this as a core workflow.
• Sending from mobile — receive only. No dedicated fax app for iOS or Android.
• Broadcast/bulk faxing — sending one fax to many recipients simultaneously.
• Fax forwarding — automatically routing received faxes to another number or email.
• Caller ID on incoming faxes — 8x8 does not display the sender's caller ID for received faxes.
• Built-in e-signatures — DocuSign or Adobe Sign required separately.
• Fax confirmation page printing — no built-in print button for confirmation records; browser print only.

Is 8x8 Fax HIPAA Compliant?

Yes — 8x8 X Series plans are HIPAA compliant and include a signed Business Associate Agreement (BAA).

This is a meaningful differentiator from some UCaaS competitors. Unlike standalone RingCentral Fax, which does not provide a BAA for standalone fax customers, 8x8 X Series subscribers can obtain a BAA covering the full platform — including fax.

For healthcare organizations, the presence of the BAA is critical. See our complete HIPAA fax compliance guide and BAA for fax service guide for the full picture of what a signed BAA requires.

Who Should Use 8x8 for Fax?

8x8 Fax Alternatives

If 8x8 isn't the right fit for your fax needs, dedicated fax services offer more fax-specific features, lower costs, and transparent pricing — without requiring a full UCaaS subscription.

mFax Business: The Purpose-Built Alternative

mFax Business is built around fax — not bundled into a larger platform. It includes:

• A signed BAA on every plan (starting at about $9/mo)
• Virtual fax numbers for your team
• Full mobile send and receive (iOS and Android)
• Shared dashboard for team management
• Delivery confirmation and audit logs
• No UCaaS overhead — you pay for fax, not phone, video, and messaging

For individual or occasional faxing, the mFax app sends a fax from any phone in under 2 minutes with no long-term commitment. See how mFax compares to other business fax services in our best business fax services guide.

Final Verdict

8x8 fax works well if you're already an 8x8 Work customer. For organizations using 8x8 for voice, video, and messaging, the bundled Internet Fax adds meaningful value at no extra cost — and the HIPAA BAA coverage is genuine and available on all X Series plans, unlike some competitors.

Outside that context, the case weakens significantly. No email-to-fax, no mobile sending, opaque quote-only pricing, and a 60-day storage limit are material gaps compared to dedicated fax services. If your primary requirement is fax — especially for healthcare, legal, or insurance workflows — you'll get more features, clearer pricing, and often a lower total cost from a purpose-built service.

Choose 8x8 fax if your organization already uses or is evaluating 8x8 Work as a full UCaaS platform, and fax is one of many communication needs you want to consolidate.

Choose mFax Business if HIPAA-compliant team faxing is the core requirement. mFax Business starts at about $9/mo with a signed BAA, virtual fax numbers, full mobile send and receive, and a shared dashboard — without paying for a phone system you don't need.

Choose eFax or Fax.Plus if you need built-in e-signatures alongside your fax workflow — both include signing capabilities that 8x8 lacks.

For occasional faxing, skip a monthly subscription entirely. The mFax app lets you send faxes on a pay-as-you-go basis from your phone. See our pay-as-you-go fax guide for the full range of no-commitment options.
