Do not forward a purported government document until you have verified it through the issuing agency or an authoritative government repository. Find the official copy, validate a PDF’s digital signature in Adobe Acrobat or Reader when one is present, and contact the agency through independently obtained details if no public copy exists. A seal image, screenshot, forwarded attachment, apostille, or caller ID is not proof by itself.
What “authentic” means in this context
Document verification has several different questions, and a document can pass one while failing another:
As an Amazon Associate I earn from qualifying purchases.
- Origin: Did the stated agency or official actually issue this file?
- Integrity: Has the file changed since it was signed or certified?
- Content: Are the statements, dates, orders, or allegations in it true and current?
- Legal authentication: Does it have the certificate, apostille, or other form required for a particular legal use?
A validated digital signature can provide evidence about origin and file integrity. It does not prove every assertion in the document. The U.S. Department of State makes the same distinction for authentication certificates: “Authentication does not verify the contents of a document. Authentication acknowledges the seal and signature of the official and not the document itself.”

Choose the right verification route
| Situation | Strongest first check | What to inspect |
|---|---|---|
| Public federal publication | Compare it with the copy on the issuing agency’s site or GovInfo, the Government Publishing Office’s official-publication service. | Matching title, publication or case number, date, edition, pages, and any validated PDF signature. |
| Agency record that is not posted publicly | Contact the issuer using details found independently on its official site. | Case ID, reference number, FAC number where applicable, named official, and the agency’s response. |
| File received in a suspicious email, text, or call | Do not use the message’s links, attachments, QR codes, or phone number. Reach the agency independently. | Whether the agency confirms the message and document through a separate channel. |
| Document intended for use in another country | First verify the issuing record, then check the destination’s apostille or authentication requirement. | Required certificate, issuing authority, destination country, and the official signature, stamp, or seal being certified. |
Step 1: Record identifying details before you search
Save the file without altering it, then write down the details an agency employee could use to locate the record. Record:
- the purported department, bureau, court, or other issuer;
- the exact title and document type;
- publication, case, order, or reference number;
- date of issue, revision date, and effective date if shown;
- the name and title of any signing official;
- the URL, email address, phone number, or QR code displayed in the document or message;
- the name of the sender and the date and time you received it.
Do not assume that polished formatting, a government logo, a seal graphic, or official-sounding language makes the file genuine. These elements can be copied into a forged document. Your notes should support an independent search rather than send you back to a contact route supplied by the questionable file.
Step 2: Start from an official source you find independently
Type or locate the agency address yourself
Use a known government portal, a saved bookmark you trust, or an address you enter manually. Do not click the link in the message that delivered the document. A convincing domain name can lead to a look-alike site, and a QR code can open a destination controlled by someone else.

One-click scans. No signup required.
Find the agency’s own copy
Search the agency’s publication, press-release, court, enforcement, or document database for the title and identifier you recorded. Compare the complete file, not just a first page or screenshot. Check the number of pages, headings, footnotes, tables, attachments, revision markings, and dates. A genuine agency page may contain a newer version than the one circulating.
Use an authoritative federal repository when appropriate
GovInfo is a Government Publishing Office service for official federal publications. GovInfo describes digital signatures on its PDFs as evidence that the file is the official document, has not been fabricated, and was disseminated by GPO in that form. A repository copy is a stronger starting point than a forwarded attachment, but it still must match the record you are trying to verify.

Step 3: Validate a signed PDF in Adobe Acrobat or Reader
Many, but not all, GovInfo PDFs carry digital signatures. A browser can display the pages without performing the signature-validation workflow, so use the desktop version of Adobe Acrobat or Adobe Reader when a signed PDF is involved.
- Download the file from the official repository or agency page. Keep the original downloaded file separate from any copy you received in a message.
- Open it in Adobe Acrobat or Reader. If the file opens in a browser tab, choose the option to download it and then open the downloaded file in the Adobe application.
- Open the signature panel. Look for the signature indicator or the panel that lists signatures and certification details.
- Run validation. Use the application’s signature-validation command and wait for the result rather than relying on a visible signature graphic.
- Inspect the signer. Confirm the signer’s identity and the certificate information shown by Acrobat. A name printed on the page is not the same as a cryptographically validated signer identity.
- Check the document status. The result should indicate whether the signature is valid and whether the file changed after signing or certification. Read any warning about an untrusted certificate, an expired certificate, or modifications.
- Compare the validated file with the circulated copy. A valid signature on the official download does not authenticate a different attachment. File name, page count, hash or other file details, and visible content should correspond.
A valid result is evidence about that particular file, its signer, and its post-signing integrity. It does not prove that the signer’s statements are factually correct, that the policy remains in force, or that a later amendment has not superseded it.
Why a signature picture is not enough
A scanned signature or an image pasted into a PDF can be copied without detection. The National Archives Office of the Federal Register states that a scanned and converted PDF is not an original signature. Only the application’s validation result and certificate details provide the technical evidence associated with a digital signature.
What a warning means
- No signature present: The file may still be an official publication, but you must rely on the authoritative repository or agency confirmation.
- Signature cannot be validated: Do not treat the signature as proof. Obtain a fresh copy from the official source and follow that agency’s instructions.
- Document changed after signing: Determine what changed. A later authorized update may be legitimate, but an unexplained alteration requires confirmation.
- Signer or certificate is not trusted: Verify the signer through the agency, not through a contact detail embedded only in the PDF.
Step 4: Confirm records that are not publicly posted
Some notices, investigative records, correspondence, and case documents will not appear in a public repository. In that situation, contact the purported issuer through an official contact page you found independently. Do not call a number printed only in the document or reply to the message that delivered it.
Tell the agency exactly what you are checking and provide the identifying information it can search:

- document title and date;
- name of the alleged issuing office or official;
- how and when you received the document;
- the specific question: whether the agency issued this document and whether the version you have is current.
OFAC’s guidance for a non-public OFAC document directs people to contact the agency and reference the case ID or FAC number. Other agencies may have their own status pages, list checks, or records-request procedures. Ask what verification method applies to that document type and keep the response with your file.

Login.gov warns that suspicious messages should be checked before clicking links or downloading attachments. It also warns that caller ID can be faked, so the displayed number alone is not evidence that a call came from a government office.
Pause immediately when a message:
- creates urgency, threatens arrest, penalties, account closure, or loss of benefits;
- requests passwords, one-time codes, bank details, Social Security numbers, or identity documents before you can verify the sender;
- asks you to install software, enable macros, or move the conversation to an unfamiliar channel;
- contains a shortened link, unexpected attachment, QR code, or mismatched sender address;
- insists that you keep the matter secret or avoid the agency’s normal public contact channels.
Navigate to the agency’s official site yourself, locate its published contact method, and ask whether the message and attachment are genuine. If you already opened the file, do not forward it or enter credentials from a link in it. Preserve the message and attachment for the agency’s security or fraud-reporting team, and run your normal security checks on the device.
Step 6: Keep authenticity separate from legal use abroad
An apostille or authentication certificate is designed for a legal-use situation, commonly when a document issued in one country must be presented in another. The appropriate route depends on the destination country and the type of official signature, stamp, or seal involved.
These certificates authenticate the official signature, stamp, or seal; they do not establish that the underlying statements are true. Therefore:

- Confirm the document’s origin with the issuing agency or repository.
- Ask the receiving authority in the destination country whether an apostille or an authentication certificate is required.
- Use the designated authority for the issuing jurisdiction and document type.
- Check that the certificate corresponds to the official signature, stamp, or seal on the document.
A certificate cannot rescue a forged document, and a genuine document may still be rejected if it lacks the form required by the destination authority.

Assuming every government PDF has a digital signature
GovInfo signs many PDFs, but no rule says every government document must carry one. Absence of a signature is a reason to use repository or agency confirmation, not an automatic finding that the document is fake.
Validating the wrong copy
A signature can be valid on the file you downloaded while the attachment you received contains different pages. Always compare the exact files.
Recommended Free Tools
Confusing a valid signature with truthful content
The signer and file may be genuine while the document is outdated, misinterpreted, incomplete, or describing allegations rather than established facts. Check effective dates, amendments, and the agency’s current explanatory material.
Using contact information supplied by the suspect document
A forged document can route you to a fake phone line, email address, or website. Independent discovery of the contact route is essential.
Sharing first and correcting later
Recipients may act on a document before a correction reaches them. Keep the file private until verification is complete. If you already shared it, send a clear correction identifying the earlier file as unverified and provide the authoritative source or agency confirmation when available.
A practical pre-sharing checklist
- Have I identified the issuing agency, document type, number, date, and named official?
- Did I reach the agency or repository independently rather than through the document or message?
- Does an official copy match every material page and attachment?
- If the PDF is digitally signed, did Acrobat or Reader show the signer and validation status?
- Did I check whether the file changed after certification?
- If no public copy exists, did the agency confirm it through an official channel?
- Am I describing what has been verified without claiming that the document’s contents are automatically true?
- If the document is for use abroad, did I separately confirm the destination’s apostille or authentication requirement?
- Have I removed personal information and warned recipients about any remaining uncertainty?
What to do when verification fails
Stop sharing the document and label your local copy as unverified. Do not edit it to “fix” apparent errors, because changes can destroy useful evidence. Record where it came from, preserve the original message and attachment, and report the suspected impersonation or forgery to the real agency through its official channel. If the document requests money, credentials, or sensitive information, contact the relevant security, fraud, or identity-theft reporting service using details obtained independently.
