Why Do Banks, Doctors, and Lawyers
Still Require Fax in 2026?

If you have ever been asked to fax medical records, prescription requests, or referral forms, you are not alone. The healthcare industry remains one of the largest users of fax technology, and the reason comes down to one word: HIPAA.

The Health Insurance Portability and Accountability Act (HIPAA) establishes strict rules for how protected health information (PHI) can be transmitted. Fax has specific legal protections under HIPAA that make it an accepted and preferred method for transmitting sensitive medical data. According to the U.S. Department of Health and Human Services HIPAA FAQ, covered entities may use fax machines to transmit PHI, provided they apply reasonable safeguards.

Beyond legal compliance, fax provides something email cannot easily replicate: a verifiable paper trail with delivery confirmation. When a hospital sends patient records to a specialist, the fax confirmation page serves as proof of delivery — a critical requirement in malpractice disputes and insurance audits. Studies from the healthcare industry consistently show that the majority of healthcare communication still relies on fax, with estimates ranging from 70 to 90 percent of inter-provider communication using fax as the transmission method.

Hospitals, clinics, pharmacies, and insurance companies all continue to use fax for prescription requests, prior authorizations, patient referrals, lab results, and claims processing. The systems are deeply embedded in healthcare workflows, and the regulatory framework reinforces their continued use.

The legal profession relies on fax for a fundamental reason: evidence of delivery. When an attorney sends a document via fax, the transmission confirmation serves as legally admissible proof that the document was sent and received at a specific time. This is critical for meeting court deadlines, filing motions, and serving legal notices.

Many courts and government agencies still require fax for specific filings. While electronic filing systems have expanded, they are not universal — particularly in smaller jurisdictions, state courts, and administrative agencies. Attorneys handling cases across multiple jurisdictions often encounter at least one office that requires faxed documents.

Attorney-client privilege adds another layer. Fax transmissions are point-to-point — the document travels directly from sender to receiver without being stored on intermediate servers. This reduces the risk of privileged information being accessed by unauthorized third parties, a concern that is more pronounced with email, which routes through multiple servers and may be stored in cloud systems outside the firm's control.

Legal documents commonly transmitted by fax include contracts, affidavits, court filings, settlement agreements, notarized documents, and correspondence between opposing counsel. The legal industry's reliance on fax is not about being behind the times — it is about meeting specific evidentiary and procedural requirements.

Banks, credit unions, mortgage companies, and brokerage firms use fax for regulatory compliance and fraud prevention. Financial regulators including the SEC and FINRA have historically recognized fax as an accepted method for transmitting sensitive financial documents, and many internal compliance policies still mandate fax for specific transaction types.

Fax is harder to intercept than email. While email passes through multiple servers and can be compromised at any point along the route, fax transmissions travel over dedicated phone lines as analog signals. This makes man-in-the-middle attacks significantly more difficult compared to email interception.

Know Your Customer (KYC) requirements also drive fax usage. When banks need to verify customer identity, they often require faxed copies of identification documents, signed authorization forms, and account verification letters. Wire transfer authorizations, loan applications, account dispute forms, and beneficiary change requests are all commonly handled by fax in the financial industry.

Federal, state, and local government agencies continue to accept and often require faxed documents. The Social Security Administration, Internal Revenue Service, state Departments of Motor Vehicles, immigration offices, and countless other agencies list fax numbers on their forms and websites as an accepted submission method.

The reasons are both practical and institutional. Government IT systems often lag behind the private sector, and many agencies operate on legacy systems that were built around fax-based workflows. Upgrading these systems across thousands of offices is expensive and slow. Beyond technology, government agencies require audit trails and chain-of-custody documentation that fax naturally provides. Every fax transmission generates a confirmation record with a timestamp, sender number, receiver number, and page count — exactly the kind of documentation that government record-keeping demands.

Common government fax use cases include tax document submissions to the IRS, Social Security disability applications, immigration form submissions to USCIS, state DMV paperwork, permit and license applications, and Freedom of Information Act (FOIA) requests. If you interact with government agencies, you will almost certainly need to send a fax at some point.

The security comparison between fax and email comes down to how data travels from sender to receiver. Email messages route through multiple servers — your email provider, the recipient's email provider, and potentially several relay servers in between. At each point, the message can be intercepted, copied, or stored. Even with encryption, email metadata (sender, recipient, subject line, timestamps) is visible to intermediaries.

Fax uses point-to-point transmission over phone lines. The document travels directly from the sending device to the receiving device without being stored on intermediate servers. This makes interception significantly more difficult. An attacker would need physical access to the phone line between sender and receiver — a far more difficult proposition than intercepting email traffic.

From a legal perspective, fax transmissions are protected under the Telephone Consumer Protection Act (TCPA), which provides federal legal protections for communications sent over phone lines. Email does not have equivalent federal protections. This legal framework is one reason why regulated industries — healthcare, legal, financial — continue to prefer fax over email for sensitive document transmission.

None of this means email is inherently insecure or that fax is perfect. Both have their place. But for regulated industries that need legal protections and verifiable delivery, fax provides guarantees that email currently cannot.
