Do not forward a purported government document until you have matched it to a copy on the issuing agency’s official website or an authoritative government repository. For a digitally signed federal PDF, open it in Adobe Acrobat or Reader, validate the signature, and inspect the signer and change status. If no public copy exists, contact the agency through contact details you found independently and quote the document’s case or reference number. A seal image, screenshot, forwarded attachment, or caller ID is not proof on its own.
What counts as convincing verification?
Verification has three separate questions, and a document can pass one without passing the others:
- Origin: Did the named agency or an authorized official issue this file?
- Integrity: Is the file the same one that was signed or published, or has it been edited since then?
- Substance: Are the statements in it accurate, current, and legally meaningful?
An official repository copy and a validated digital signature are strong evidence about origin and integrity. They do not make every factual claim in the document true. Legal authentication has a different purpose again: an apostille or authentication certificate can verify an official signature, stamp, or seal for a specified use, but it does not certify the document’s contents.
The steps below use U.S. federal examples. State, local, tribal, and foreign agencies may publish records in different systems and may require different confirmation procedures.

Follow this verification sequence
1. Record the document’s identifying details
Before searching, make a short inventory from the file and the message that carried it. Record the agency named as issuer, the exact title, publication or case number, date, named official, and any FAC number or other reference identifier. Preserve the original filename and the message headers if you may need to report fraud. Do not edit the file while investigating; make a working copy if you need to annotate it.
These details let you search an authoritative catalogue and give an agency enough information to locate its record. A vague description such as “the notice I received” is much less useful than a publication number, case ID, and issue date.
2. Start at a trusted government address
Type the agency’s known web address yourself or reach it through a government portal you already trust. Do not use the link, QR code, email address, or telephone number supplied only in the questionable document. Look for the agency’s publications, press-release, legal-notice, case-status, or contact section and search there for the title or identifier.

For U.S. federal publications, GovInfo, a Government Publishing Office service, is an authoritative repository for many official publications. Compare the downloaded repository file with the copy you received. Check the title page, issuing office, publication number, date, page count, appendices, and visible revision information. A matching title alone is not enough if the date or edition differs.
3. Compare the files, not just the cover page
Open the repository copy and the received copy side by side. Confirm that substantive pages, tables, footnotes, signatures, attachments, and metadata are consistent. A scammer can paste a genuine first page onto altered pages or change a deadline in an otherwise authentic notice. If the repository offers a checksum or a download generated from the same record, keep that value with your verification notes; if it does not, rely on the repository comparison and signature checks described below.
Save the official copy from the agency or repository, note the retrieval date, and keep the original separately. Do not overwrite the suspicious file, because preserving it can help the agency or an incident-response team investigate.

How to validate a signed PDF
Many, but not all, GovInfo PDFs carry digital signatures. A visible signature graphic or a scanned handwritten signature is not the same as a cryptographically validated signature. The National Archives Office of the Federal Register explains that a scanned and converted PDF is not an original signature.
Recommended Free Tools
Use desktop Acrobat or Reader
GovInfo recommends Adobe Acrobat or Reader for authenticated PDFs. A browser PDF viewer may display the pages without running the signature-validation workflow, so use the desktop application when the file is supposed to be signed.
- Download the PDF from the official repository or agency site. Keep the downloaded file unchanged.
- Open it in Adobe Acrobat or Reader, not only in a browser tab.
- Open the Signatures panel. Depending on the application version, select the signature field or the signature status bar to view details.
- Run Validate Signatures if validation has not happened automatically.
- Inspect the validation result, the signer’s identity, the certificate chain or trust information shown by the application, and the time or timestamp information when available.
- Check the document-integrity message. It should indicate whether the signed file has changed after certification. Treat warnings about modified bytes, an invalid certificate, or an unknown signer as reasons to stop and confirm with the issuer.
- Record the result, application name and version, and file name in your notes. If you share the file later, retain the validated original rather than exporting it through software that could invalidate the signature.
A valid result is evidence that the certificate signed that file and that the signed bytes have not changed according to the validation process. It is not a finding that the document’s claims, policy interpretation, or demand for payment is correct. If the signature panel is missing, the file is not necessarily fake; it may simply be unsigned, flattened, scanned, or produced by an agency that uses another publication system.

Understand common signature outcomes
| What you see | What it establishes | What to do next |
|---|---|---|
| Signature validates and the signer is identified | The application accepted the certificate and found no disallowed post-signing change in the signed file. | Still compare the file with the agency’s published copy and assess the document’s substance separately. |
| Signature is present but reports changes after signing | The file differs from the signed version in a way the application flags. | Do not share it as official; obtain a fresh copy from the issuer. |
| Signature is present but signer or certificate is not trusted | The application cannot establish a trusted signer under its certificate checks. | Confirm the signer and file through the agency’s independent contact route. |
| No digital signature is present | Nothing in the file provides a cryptographic signature for validation. | Use repository comparison and direct issuer confirmation; do not infer fraud solely from the absence of a signature. |
When the document is not publicly posted
Some case notices, correspondence, enforcement records, and individually addressed documents are not available in a public repository. In that situation, use the agency’s official contact page, directory, or case-status system found independently of the questionable file. Call, email, or submit a verification request through that route and provide the document’s title, date, case ID, publication number, or FAC number.
OFAC’s FAQ 468 gives this model for a non-public OFAC document: contact the agency and reference the case ID or FAC number. Follow the agency’s stated process rather than asking an unverified sender to “confirm” its own attachment. Ask whether the document was issued, whether the version and date are current, and whether any action or deadline in it is genuine. Do not send passwords, payment-card details, one-time codes, or identity documents merely because the attachment asks for them.
Keep a record of the official channel used, the date and time, the staff member or ticket number if supplied, and the answer. If the agency will not confirm by email, use its published telephone or secure portal instead. An agency’s refusal to discuss a protected record is not proof that the file is authentic; it only means you need to follow its privacy and disclosure rules.

Documents delivered in suspicious messages
Urgency, threats of arrest or account closure, requests for sensitive information, unexpected refunds, and instructions to pay through an unusual method are warning signs. Login.gov advises people not to click links or download attachments before checking a suspicious message. It also warns that caller ID can be faked, so the number displayed on your phone is not an independent identity check.
Use a clean route to the agency
- Do not click the message’s links, scan its QR code, open its attachment, or reply with personal information.
- Navigate separately to the agency’s known website or a government portal.
- Find the contact page or service named by the message and use the published route.
- Ask whether the message and document were sent, quoting only the necessary identifying details.
- If you already opened the file, disconnect from sensitive accounts if appropriate, run your organization’s malware checks, and report the message through your email provider or agency reporting channel.
A message can contain a genuine document and still be a phishing attempt if the sender wants you to log in at a counterfeit site. Conversely, a real agency message may use a third-party delivery system. Verification must therefore cover both the file and the route by which the sender asks you to act.
Do not confuse authenticity with legal authentication
| Check or credential | Primary question answered | What it does not prove |
|---|---|---|
| Official agency or GovInfo copy | Is this the version published or provided by the named government source? | That every statement is true or that the document applies to your situation. |
| Validated digital signature | Did the identified certificate sign this file, and has the signed file changed? | That the signer had authority for every claim or that the underlying facts are correct. |
| Visible seal, logo, or signature image | Only that an image was placed on the page. | That the image is genuine, current, or attached to an unaltered file. |
| Apostille or authentication certificate | For an eligible legal-use route, does the certificate acknowledge the official seal or signature? | The truth of the document’s contents. The U.S. Department of State states: “Authentication does not verify the contents of a document. Authentication acknowledges the seal and signature of the official and not the document itself.” |
If a foreign authority, court, school, or employer asks for an apostille or authentication certificate, determine the destination country and the issuing authority’s signature type before submitting anything. That legal-use process is separate from checking whether a file circulating online is the genuine, current document.
Choose the route that fits the document
| Situation | Best first check | Evidence to retain |
|---|---|---|
| Public U.S. federal publication | Find the agency or GovInfo copy, then validate a PDF signature if one is present. | Official download, retrieval date, signature status, signer details, and comparison notes. |
| Agency record not publicly posted | Contact the issuer through an independently found official channel and provide the case or reference identifier. | Ticket, call record, or written confirmation and the exact version discussed. |
| Attachment or link in an unexpected message | Do not interact with it until the purported agency confirms it through a separate official route. | Original message, sender details, and confirmation from the agency. |
| Document intended for use abroad | Verify the issuing record first, then check whether the destination requires an apostille or authentication certificate. | Issuing-agency confirmation and the destination authority’s requirements. |
Red flags that require a pause
- The document uses a seal or signature image but has no verifiable publication or case identifier.
- The date, agency name, address, typography, or legal citation conflicts with the agency’s official site.
- A deadline is extremely short and the sender insists that you keep the matter secret.
- The attachment asks you to enable macros, install software, reveal a password, or pay through cryptocurrency, gift cards, or a personal account.
- A link’s visible text names a government service but its actual destination is a different domain.
- The PDF has unexplained edits, missing pages, inconsistent fonts, or a signature warning after validation.
- The sender refuses to let you verify through the agency’s published contact page.
None of these signs alone proves forgery. They tell you to stop acting on the document until an independent source resolves the discrepancy.
A safe sharing checklist
- Identify the purported issuer, document type, title, number, date, and named official.
- Find the issuer’s official website or an authoritative government repository without using the questionable message’s links or contact details.
- Download the authoritative copy and compare all substantive pages and identifiers.
- Open a signed PDF in desktop Acrobat or Reader, validate the signature, and inspect signer and change-status information.
- If no public copy exists, contact the issuer independently and quote the case, reference, or FAC number.
- Separate the question “Is this the issued file?” from “Are its claims true?” and from “Does it meet a foreign legal-authentication requirement?”
- Remove or redact unnecessary personal information before sharing a verified copy, while preserving the original for your records.
- When forwarding, include the official repository location or the agency confirmation date so recipients can repeat the check.
Limits of a federal verification method
GovInfo’s signature workflow applies to signed PDFs in that repository; it does not mean every government document should carry a digital signature. State and local portals may use document-management systems, public-records indexes, or secure case portals instead. Tribal and foreign authorities may publish records in other languages, use different certificate authorities, or require in-person confirmation.
When the issuer, document type, or destination country changes, keep the same principles: start from an independently trusted official channel, match identifiers and versions, validate technical signatures where available, and ask the issuer about anything that remains uncertain. Never let a familiar logo, a forwarded copy, or a caller’s confidence replace that independent check.
