For contractors, citizens & healthcare providers
Fax documents to any government agency — with certified proof of delivery
Every fax includes a tamper-evident certified receipt with delivery timestamp and SHA-256 document hash. No account required. Works from any device.
Why the receipt matters
Proof of delivery that holds up when deadlines are disputed
Government submissions are deadline-sensitive. A benefit claim filed a day late can affect the effective date. A contractor proposal that arrives after the cut-off is disqualified. An administrative appeal received outside the response window may be dismissed.
FaxSeal's Certified Delivery Receipt is a timestamped record of exactly what was sent, to which number, and when the receiving line confirmed receipt. It is not a marketing claim — it is a technical artifact you can verify independently.
Send a fax and get a receipt →Carrier-confirmed delivery timestamp
The exact date and time the receiving agency's fax machine confirmed receipt — not when we sent it.
SHA-256 document hash
A cryptographic fingerprint of the exact file transmitted. If the file you kept is unchanged, its hash matches the receipt. If even a single character was altered, it does not.
Recipient fax number on record
The number dialed is recorded in the receipt. Useful if an agency later claims the submission went to the wrong office.
Permanent verification URL
A permanent link to verify the receipt independently — share it with a contracting officer, hearing officer, or agency contact.
Common uses
Who uses FaxSeal for government submissions
FaxSeal is used by the people who send faxes to government — not by government agencies as an IT system.
FOIA & records requests
Freedom of Information Act requests to federal agencies must be submitted in writing. Many agencies list a fax number as the accepted submission method. The certified receipt gives you a timestamped record of when the agency received the request — which starts the statutory response clock.
VA claims & benefits
Veterans submitting benefit claims, community care referrals, and supporting documentation to VA regional offices or medical centers. The VA accepts fax for most claim submissions. A certified receipt establishes the filing date, which can affect effective dates for benefits.
Government contractor submissions
RFP responses, proposal enclosures, subcontractor agreements, and regulatory filings under federal contracts. Many contracting offices still specify fax as an accepted delivery method with hard deadlines. The SHA-256 receipt proves what was sent and when.
Administrative court & tribunal filings
Filings with administrative law judges, EEOC, Social Security appeals, immigration courts, and regulatory hearing offices. These bodies routinely accept fax. A certified receipt with delivery timestamp matters when deadlines are contested.
CMS & Medicare prior authorization
Prior authorization requests to CMS-administered plans, Medicare Advantage, and Medicaid programs. Most plans publish a fax number as the primary PA submission channel. The certified receipt documents the submission date, which is critical if an authorization is denied as untimely.
State & local agency submissions
Licensing boards, state benefit offices, county courts, municipal permitting offices, and regulatory agencies. State and local agencies are often more accessible than federal — a department head can approve a credit card purchase without IT procurement. Fax is still the mandated channel for many state submissions.
How it works
Three steps, receipt in minutes
Upload your document
Upload a PDF or use the built-in phone camera scanner for paper documents. No conversion required — most government submissions are already PDF.

Use the number published on the agency website, your denial letter, or the solicitation. FaxSeal supports US, Canada, and international government fax numbers.

State and local agencies: use FaxSeal without IT procurement
County clerks, state licensing boards, municipal courts, and administrative offices can use FaxSeal on a department credit card — often under existing micro-purchase authority with no formal IT approval required.
Credit bundles never expire and carry over. Buy once, use across your team from the dashboard. No vendor agreement, no procurement paperwork for small-dollar purchases.
Frequently asked questions
Does FaxSeal have FedRAMP authorization?
No. FaxSeal is not FedRAMP authorized and is not designed for use as an official government IT system. FedRAMP applies to cloud services that government agencies operate internally for their own data. FaxSeal serves the people who send documents to government agencies — contractors, citizens, healthcare providers, and lawyers — not the agencies themselves.
Is the certified receipt legally admissible?
The certified delivery receipt is a contemporaneous business record documenting transmission and carrier-confirmed delivery. It includes a cryptographic hash of the transmitted file. Whether it is admissible in a specific proceeding depends on the rules of that forum — FaxSeal does not provide legal advice. The receipt provides strong factual evidence of when a document was sent and received, which is what most administrative and procurement disputes require.
Can I send a fax to any federal agency?
Yes, provided the agency publishes a fax number for that purpose. Most federal agencies maintain fax lines for public submissions — FOIA offices, benefits claim offices, contracting offices, and regulatory hearing dockets all commonly list fax numbers. FaxSeal supports any US fax number.
What if I need to prove the document content, not just delivery?
The SHA-256 hash in the certified receipt is a tamper-evident fingerprint of the exact file transmitted. If there is ever a dispute about what was sent, the hash proves it. Using any SHA-256 tool, you can verify that the file you kept matches the hash in the receipt — no third party involvement required.
Do I need an account?
No. FaxSeal requires no signup, login, or subscription. Upload your document, enter the fax number and your email, pay per fax, and send. The receipt is emailed to you immediately. A pay-per-fax send typically falls well under the federal micro-purchase threshold for government charge cards.
What happens if the fax fails to deliver?
You are never charged for an undelivered fax. If delivery fails — busy line, disconnected number, carrier error — the authorization is released and you pay nothing. Retry once you have confirmed the current fax number for the office. Agency fax numbers change; always verify against the agency's current website before filing deadline-sensitive documents.
Can state and local governments use FaxSeal as a department?
Yes. State and local agencies, county offices, and municipal departments can purchase fax credits on a standard credit card — often under existing micro-purchase authority without IT procurement. Credits never expire and can be shared across a team after sign-in. For ongoing volume, the pay-as-you-go credit model keeps costs predictable.
