What a national seal cross reference does
A national seal cross reference is a tool or document that matches a seal image to the government body or organization that issued it. When you see an official seal on a document, letter, or website and want to know which agency created it or whether it is authentic, a cross reference tells you what that seal belongs to and how to verify it.
The U.S. government uses hundreds of seals across federal, state, and local agencies. Each seal is unique to that body — the Department of State has one, the Social Security Administration has another, your state's Department of Motor Vehicles has its own. A cross reference works like a visual directory: you find the seal, look it up, and learn which organization issued the document you are holding.
This matters because seals are used to certify official documents, mark authentic communications, and prove that something came from a real government source. Knowing how to cross-reference a seal helps you verify that a letter claiming to be from a government agency is actually from that agency, not a forgery or scam.
Key Takeaways

- State seals are typically found through your state's Secretary of State office or state government website.
- The National Archives holds historical records of seal designs and can confirm whether a seal design is authentic.
- Many government agencies publish their seal guidelines publicly so you can compare an image you have against the official version.
- If you suspect a seal is forged or used fraudulently, you can report it to the agency it claims to represent or to the U.S. Postal Inspection Service if it arrived by mail.
Where to find federal seals and their meanings
The General Services Administration (GSA) publishes the official seals of federal agencies on its website. You can search by agency name or browse by department. Each entry includes the seal image, the official name of the agency, and sometimes the year the seal was adopted or last modified.
The GSA's seal collection covers executive branch agencies, independent agencies, and boards and commissions. If you are looking up a seal from a major federal department — State, Defense, Treasury, Interior, Commerce, Labor, Health and Human Services, Education, Veterans Affairs, Homeland Security, or others — the GSA site is the authoritative source.
For older or historical seals, the National Archives maintains records of seal designs going back decades. This is useful if you are verifying a document from several years ago and want to confirm the seal design matches what was in use at that time.
How to find state and local seals
State seals are usually found through your state's Secretary of State office. Most states publish their official seal on the Secretary of State website, along with a description of what the seal represents and when it was adopted. Some states also publish guidelines for how the seal should be used and reproduced.
County and city seals are less centralized. Your county clerk's office or city government website usually displays the local seal and can confirm whether a seal you have seen is authentic. If you are in doubt, calling the county clerk or city hall directly is often the fastest way to verify a local seal.
Many state and local government websites now include seal images in their official document templates, so you can compare a seal on a letter or certificate against what appears on the agency's own website.
How to verify a seal is not forged
Start by comparing the seal you have against the official version from the agency's website or the GSA database. Look for exact matches in the design, text, colors, and proportions. Forged seals often have subtle differences — misspelled words, slightly different fonts, wrong colors, or missing elements.
Check the context. A real government letter will have the agency's official letterhead, contact information, and usually a signature from a named official. Scam letters often have generic language, vague sender information, or ask you to call a number or visit a website that does not match the agency's real contact details.
If you are uncertain, contact the agency directly using a phone number or website address you find independently — not from the document itself. Call the main switchboard or visit the official website and ask whether the letter or document is authentic. Government agencies expect these calls and can usually confirm or deny a document in minutes.
What to do if you find a forged seal
If you receive a document with a forged government seal, do not ignore it. Forged seals are often used in scams, fraud, or identity theft schemes. Report it to the agency whose seal was copied — they have fraud investigation units and want to know about misuse of their seal.
If the forged document arrived by mail, you can also report it to the U.S. Postal Inspection Service, which investigates mail fraud. If it arrived by email or online, report it to the Federal Trade Commission (FTC) at reportfraud.ftc.gov.
Keep the document or take a screenshot if it was digital. Include details about how you received it, what it claimed, and any contact information it provided. These details help investigators trace the source of the fraud.
Seal guidelines and official use standards
Many federal agencies publish official seal guidelines that explain how their seal should be used, sized, and reproduced. These guidelines exist partly to prevent misuse and partly to may support the seal is always recognizable. If you are checking whether a seal looks right, these guidelines can help.
The GSA also publishes general standards for how federal seals should appear in official documents. For example, seals should not be altered, rotated, or combined with other graphics in ways that distort their meaning. If a seal you see violates these standards, that is a red flag.
State and local agencies often have similar guidelines. If you work with government documents regularly, asking the agency for their official seal guidelines is a reasonable request and they usually provide them.
Frequently Asked Questions
Where can I find a list of all U.S. federal agency seals?
The General Services Administration (GSA) website maintains the most complete collection of federal seals. You can search by agency name or browse by department. The National Archives also holds historical seal records if you need to verify a seal from a past year.
Can I use a government seal on my own document or website?
No. Government seals are protected and using them without authorization is illegal. Only the agency that owns the seal can use it on official documents. If you need to display a seal for informational purposes, contact the agency first to ask for permission and guidance on proper use.
What should I do if I see a government seal used on a website that does not look official?
Compare the seal against the official version on the agency's real website. Check the domain name — scam sites often use URLs that look similar to real government sites but are slightly different. If something seems wrong, report it to the agency and to the FTC.
How do I know if a state seal on a document is real?
Visit your state's Secretary of State website and look up the official state seal. Compare the image, colors, and text against what you see on the document. You can also call your Secretary of State office directly and describe the seal to confirm it is authentic.
Are seal designs ever changed or updated?
Yes, though rarely. Some agencies have updated their seals over decades. The National Archives and the GSA both track when seals were adopted and modified, so if you are verifying an old document, you can check what the seal should have looked like in that year.
