For a U.S. government website, start with the complete hostname. An address that ends in the exact .gov top-level domain is a strong official-status signal because only verified, eligible U.S. government organizations can register and operate a .gov domain. Then compare that domain with the agency listing in USA.gov’s directory or confirm it through a government contact route you found independently.
Do not treat a padlock, government-looking logos, an agency name somewhere in a long web address, or a familiar-looking email as proof of identity. HTTPS protects the connection; it does not, by itself, establish who operates the site.

How can I tell if a government website is real?
Use two separate checks: domain evidence and organization evidence. Domain evidence asks whether the hostname ends in the exact .gov domain. Organization evidence asks whether a trusted government directory or independently obtained contact channel connects that domain to the agency or government entity you need.

- Pause. Do not enter personal information or pay simply because a link arrived by text, email, social media, or an advertisement.
- Read the full hostname. Find the address bar and identify the domain immediately before the first slash after the hostname. Check the ending, not just words that appear in the page title or path.
- Cross-check independently. Open USA.gov’s A–Z agency index yourself and compare the listed website and contact information. For a state or local service, follow the state or local resource linked from USA.gov or use a government contact method you already know.
- Confirm unusual cases. If the site uses
.com,.org, or.net, look for a direct link or confirmation from the relevant government organization. - Use HTTPS correctly. A secure connection is useful, but the padlock is not an ownership certificate.
- Stop if uncertainty remains. Ask the agency to confirm the address through a separately obtained contact route before submitting sensitive information or payment.
These steps are designed for U.S. government websites and U.S. .gov rules. Other countries may use different official domains and verification systems.
#1 Best Overall
Why the exact .gov ending matters
The Cybersecurity and Infrastructure Security Agency (CISA) .gov registry states: “Only verified U.S. government organizations can register and operate a .gov domain.” That makes the exact suffix a meaningful identity signal that ordinary commercial domains do not provide.
Eligible organizations include federal, state, territorial, tribal, county, city, special-district, school-district, and interstate government entities. A page can still be poorly maintained or contain information that is no longer relevant, but a properly registered .gov hostname indicates that an eligible U.S. government organization passed the registry’s verification process.
Look at the hostname itself. In agency.gov/services, the hostname is agency.gov and it ends in .gov. In agency.gov.example.com, the hostname ends in .com; the word “gov” is only part of a longer name and does not create a government domain. Likewise, agency-example.com/gov uses a commercial domain even though “gov” appears in the path.

A subdomain such as benefits.agency.gov still sits under the registered agency.gov domain and retains the .gov ending. Verify that the parent domain belongs to the organization you expect. A familiar agency name in a subdomain is not enough if the ending belongs to somebody else, as in agency.gov.example.com.
How to inspect a suspicious web address
Read from the right side
When an address is crowded with words, start at the end of the hostname and work left. The final label before the first slash is the key ownership portion. For a U.S. government site, that final portion should be exactly .gov. Ignore a trailing path such as /forms, /login, or /payments when deciding who owns the domain.

Watch for look-alike construction
tax-agency.gov.example.comis controlled byexample.com, not by a government agency.tax-agency-gov.comis a commercial.comdomain.- A misspelled name, extra hyphen, or unexpected country-code ending should be treated as a reason to verify the site independently.
- A shortened link can hide the destination. Open the agency’s known homepage or directory listing instead of relying on the shortened address.
Check the address after redirects
A message may begin with one link and send you elsewhere. Before signing in, uploading a document, or paying, read the final hostname shown in the browser. A government logo or familiar page design does not override a different domain.
Where can I check an agency’s real website?
USA.gov describes itself as “the official guide to government information and services.” Its A–Z index lists federal agency websites and contact information and points readers to state and local government resources. Navigate to USA.gov yourself by typing the address or using a bookmark you created earlier; do not depend on the link in a suspicious message.
Compare more than a logo. Match the agency name, website address, telephone number, mailing address, and the specific service you need. If the directory lists a different domain, use the directory’s address rather than the questionable link.
Federal agencies
- Open the USA.gov agency index independently.
- Find the agency by its official name.
- Open the listed website in a new browser tab and compare the hostname character for character.
- Use the listed contact information if the site you were sent does not match.
State, territorial, tribal, county, and city services
Local services may be hosted under a state or local government domain rather than a federal address. Use the state or local resource linked from USA.gov, then verify the service and contact details there. The same hostname test applies: identify the actual registered domain, not a department name in a path or advertisement.
Independent contact confirmation
If a site asks for a Social Security number, payment, identity document, or other sensitive material and you are unsure, call or email the agency using contact details obtained from USA.gov, a government bill you already have, or another independently known source. Do not use a telephone number or reply address supplied only by the questionable message.
Does every official government website end in .gov?
No. The exact .gov ending is a strong signal for U.S. government ownership, but some official or government-sponsored services use other suffixes. USA.gov’s linking policy includes government-sponsored sites ending in .com, .org, or .net; it gives USPS.com as an example.
Recommended Free Tools
A non-.gov address therefore deserves additional verification, not an automatic fraud verdict. Look for the government organization itself to link to or confirm the site. Branding on the page, a search-engine result, or a sponsored advertisement is not sufficient by itself.
USA.gov also links to selected external, non-government organizations as a public service. Its policy disclaims endorsement or guarantees about those organizations, services, advice, or products. A link appearing on USA.gov must therefore be interpreted in context: determine whether the destination is a government-sponsored service or an external organization and apply the organization’s own status and contact checks.
Does the padlock mean a website is official?
No. HTTPS answers a connection-security question: whether data is encrypted in transit between your browser and the server. It does not answer the identity question: who controls the domain.
CISA says new .gov domains are preloaded to require HTTPS. That supports secure connections for .gov sites, but the presence of HTTPS or a padlock alone is not proof that a site is operated by a government agency. A fraudulent or commercial site can also obtain an HTTPS certificate.
Use the padlock as one part of safe browsing, then continue with the hostname and independent agency-directory checks. Never relax verification merely because the browser displays “Secure.”
What should I do if a government website asks for my Social Security number or payment?
Stop and establish the destination first
USAGov warns that imposters can pretend to represent government agencies to gain trust and steal information or money. An unexpected demand for a Social Security number, bank details, gift cards, wire transfers, cryptocurrency, or an urgent fee is a reason to stop, even when the page uses official-looking language.
Verify the service and the payment path
- Open the agency’s website through USA.gov or an independently known bookmark.
- Find the same service from the agency’s own navigation rather than from the message’s button.
- Compare the hostname on the payment or login page with the verified agency domain.
- Contact the agency through a separately obtained phone number or email address and ask whether the request and destination are genuine.
- Do not send money while the agency’s identity or payment instructions remain unconfirmed.
If you already submitted information
Contact the real agency using an independently obtained channel and explain exactly what you provided and when. If financial information was exposed, contact the relevant financial institution promptly. Change reused passwords and monitor accounts connected to the information you disclosed. Preserve the message, address, and transaction details so the agency or financial institution can investigate.

Common situations and the right response
A search result shows a sponsored “government” page
Advertisements can appear above an agency’s genuine result. Read the hostname and open the agency through USA.gov instead of assuming the first result is official. Search ranking and advertising placement are not identity verification.

Pick the symptom - the matching free tool is one click away.
An email uses an agency seal and a familiar signature
Inspect the destination without clicking if possible, then navigate independently to the agency directory. Do not reply to the message to verify it; use a separately obtained contact route.
The page is on a legitimate .gov domain but asks for an unexpected fee
A .gov domain is an eligibility signal, not a guarantee that every request is appropriate. Confirm the specific program, fee, deadline, and payment method through the agency’s official contact information. The particular page may be outdated, misdirected, or unrelated to the service you intended.
The address is not .gov, but the agency’s site links to it
Follow the government organization’s link from its verified site and read the surrounding explanation. Confirm that the destination is the intended government-sponsored service rather than a separate external organization. Keep in mind USA.gov’s policy distinguishes government-sponsored destinations from selected external links and does not guarantee the latter.
Is a .gov domain a guarantee that the information is correct?
No. Domain eligibility identifies the type of organization allowed to operate the domain; it does not certify every page’s accuracy, freshness, accessibility, or relevance. Check the page’s date, the responsible office, the jurisdiction, and the exact program or form. If two official pages conflict, contact the responsible agency and ask which page controls.

A federal page may not contain the rules for a state program, and a city department may not administer a county service. The agency-directory match establishes who operates the site; it does not eliminate the need to read the page’s scope and eligibility requirements.
How USA.gov fits into verification
USA.gov’s SearchGov service is used on thousands of federal websites and handles more than 200 million searches a year, according to a page last updated March 3, 2026. That figure describes search-service usage, not the prevalence of scams or the success rate of any verification method.
Use USA.gov as a starting point for finding the correct agency and contact path, not as a substitute for reading the final hostname and confirming the service. When a directory entry and a message disagree, trust the independently opened directory and ask the agency to resolve the discrepancy.
What if the site is outside the United States?
The checks above are specifically about U.S. government organizations and the U.S. .gov registry. Other countries may use a national domain, a government directory, a certification mark, or another identity system. Do not assume that a country’s suffix follows the U.S. eligibility rules.

Quick Recap
A printable verification checklist
- Did I pause instead of following an unexpected request immediately?
- Did I read the complete hostname, including the ending after the final dot?
- If it claims to be U.S. government-operated, does the hostname end in the exact
.govdomain? - Did I check whether the agency and address appear in USA.gov’s directory or a linked state/local resource?
- If the address is
.com,.org, or.net, did the government organization itself link to or confirm it? - Did I treat HTTPS and the padlock as connection security only?
- Before entering sensitive data or paying, did I confirm the request through an independently obtained contact route?
