How to Receive a Fax on iPhone in 2026
To receive a fax on an iPhone, you need a fax app that assigns you a dedicated inbound fax number — incoming faxes arrive as PDFs in the app or via email.
Faxend's Pro plan ($19.99/month) includes a dedicated inbound number, HIPAA compliance, and AES-256 encryption on every page you receive.

How inbound fax works on a smartphone
A traditional fax machine listens on a phone line 24/7. Your iPhone obviously cannot do that on its own. A fax app solves this by keeping a server-side number active at all times.
When someone sends a fax to your number, the app's servers receive the transmission. They convert it to a PDF and push a notification to your phone. The whole process typically takes under two minutes from send to notification.
This is the same technology used by services like eFax and Faxend. The difference is in pricing, compliance features, and whether you get a dedicated number or a shared one.
Faxend uses the T.38 fax-over-IP protocol via the Sinch backbone, which covers 120+ countries. That means you can receive faxes from international senders without any extra setup.
What you need before you start
You need three things. An iPhone running iOS 16 or later. A fax app installed from the App Store. A plan that includes an inbound fax number.
Not every plan includes inbound receiving. Faxend's Basic plan ($2.99 one-time) and Standard plan ($9.99/month) are outbound-focused. The Pro plan at $19.99/month is the tier that adds a dedicated inbound number.
If you only expect occasional inbound faxes, some apps offer temporary or shared numbers. Read the section below on dedicated vs. shared numbers before you commit to a plan.
You will also want a PDF viewer on your phone. Apple's built-in Files app works fine. Most fax apps open received documents directly in the app anyway.
Steps to receive a fax on iPhone
Install the Faxend iPhone app from the App Store. It's free to download. You create an account during setup, which takes about 90 seconds.
Open the app and go to the plan selection screen. Select Pro ($19.99/month). This is the plan that unlocks your dedicated inbound fax number. Tap Subscribe and confirm with Face ID or Touch ID.
After subscribing, the app prompts you to choose an area code. Pick one and the system assigns you a dedicated number within seconds. Write this number down or copy it. You will share it with anyone who needs to fax you.
When iOS asks if Faxend can send notifications, tap Allow. This is how you find out a fax has arrived. Without notifications, you would have to open the app manually to check.
Give your new number to senders — doctors' offices, law firms, government agencies, whoever needs to reach you by fax. You can also add it to your email signature or business card.
When a fax arrives, you get a push notification. Open the app and tap the Inbox tab. Your fax appears as a PDF. Tap it to view, download, or forward by email. The app stores your fax history so you can access older documents any time.

Dedicated number vs. shared number
A dedicated number is assigned only to you. Anyone who dials it reaches your inbox. This is what Faxend Pro provides.
A shared number works differently. Multiple users share one number, and the app routes incoming faxes based on a cover sheet code or sender ID. This approach is cheaper but less reliable. Routing errors happen, and some senders' machines do not send the required codes.
For personal or low-volume use, a shared number might be acceptable. For healthcare, legal, or financial documents, a dedicated number is the right choice. You need certainty that a fax went to you and not someone else's inbox.
If you only need to send faxes from your iPhone and never receive them, the Basic or Standard plan covers that. See the full breakdown on the Faxend pricing page.
Apps like FaxBurner offer temporary inbound numbers for free. That works for a one-time document exchange. But a temporary number expires, so it is not suitable for ongoing business use or healthcare workflows.

HIPAA considerations for received faxes
If you work in healthcare, received faxes are subject to HIPAA's Security Rule. That rule requires encryption of protected health information (PHI) in transit and at rest.
Faxend encrypts all data with AES-256, both during transmission and in storage. This applies to every plan, including Pro. A Business Associate Agreement (BAA) is available on request, which is required under HIPAA when a vendor handles PHI on your behalf.
One thing many people overlook: your phone's lock screen. If fax notifications show a preview of the document content, that content is visible to anyone who glances at your screen. Turn off rich notification previews in iOS Settings if you handle sensitive documents.
Also consider where received PDFs are backed up. If your iPhone backs up to iCloud, faxed documents may end up there. Make sure your iCloud account uses strong authentication. The HHS guidance on covered entities is a useful reference for understanding your obligations.

Troubleshooting common issues
Fax not arriving? Check these things in order.
- Confirm the sender used the right number. A single transposed digit means the fax went elsewhere. Ask the sender to verify the number they dialed.
- Check your spam or junk folder. If you have email delivery enabled, some email providers filter fax notification emails as spam.
- Check the app's Inbox tab directly. Push notifications can fail if your phone was offline or in Do Not Disturb mode. The fax may already be there.
- Verify your subscription is active. An expired plan can disable inbound receiving. Open Settings inside the app to confirm your plan status.
- Ask the sender to resend. Older fax machines sometimes drop transmissions on noisy lines. A second attempt usually succeeds.
If you consistently miss faxes from one specific sender, the issue is often on their end. Older analog machines can struggle with VoIP-based receiving services. Asking them to send at a lower baud rate (9600 bps instead of 14400) often fixes it.
International faxes occasionally take longer than domestic ones. Faxend's 120-country coverage via Sinch handles most international traffic without issues, but peak-hour congestion at the originating carrier can add a few minutes.
