The domain name gov is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet. The name is derived from the word government, indicating its restricted use by government entities. The TLD is administered by the Cybersecurity and Infrastructure Security Agency (CISA),[1] a component of the United States Department of Homeland Security.
.gov is one of the original six top-level domains, defined in RFC 920.[2] Though "originally intended for any kind of government office or agency",[3] only U.S.-based government entities may register .gov domain names, a result of the Internet originating as a U.S. government-sponsored research network.
Other countries typically delegate a second-level domain for government operations on their country-code top-level domain (ccTLD); for example, .gov.uk is the domain for the Government of the United Kingdom, and .gc.ca is the domain for the Government of Canada. The United States is the only country that has a government-specific top-level domain in addition to its ccTLD (.us), a direct result of the United States federal government's role in the creation of the Internet.
.gov domains are registered at get.gov.
is one of the original top-level domains created in 1984[4] (the other five being,,,, and). The first site registered was in June 1985.[5]
Beginning in 1997, the General Services Administration (GSA) began administering .gov. In February 2011, the GSA selected Verisign to manage the registry services, replacing Native Technologies, Inc.[6]
Responsibility for the TLD was transferred to the Cybersecurity and Infrastructure Security Agency (CISA) under the DOTGOV Online Trust in Government Act of 2020,[7] part of the Consolidated Appropriations Act, 2021.
In January 2023, CISA selected Cloudflare to replace Verisign in providing registry services. Cloudflare will also provide authoritative DNS services for the .gov domain.[8]
Many governments in the United States use a .gov domain, though most use .us (e.g., leg.state.nv.us), .com (e.g., myflorida.com), .org (e.g., lacity.org), or other TLDs (e.g., senate.mn).[9] The full list of registered .gov domains is published at get.gov/data.[10]
During GSA's administration of .gov, registration and annual renewal fees peaked at $400 per year.[11] When CISA began managing the TLD in April 2021, all fees were removed.[12]
Federal Executive branch policy requires the use of .gov for civilian agencies,[13] but some U.S. government-related websites use non-.gov domain names, including the United States Postal Service (e.g., usps.com) and various recruiting websites for armed services (e.g., goarmy.com). The United States Department of Defense and its subsidiary organizations typically use the .mil sTLD instead of .gov.
U.S.-based government organizations and publicly controlled entities are eligible to obtain a .gov domain. This includes federal, state, local, or territorial government, as well as any tribal government recognized by the federal government or a state government.[14]
To register a .gov domain, an authorization letter must be submitted to CISA. The signer of the letter differs by entity type, but it is typically an agency's head, chief information officer (CIO), or highest-ranking or elected official.
Historically, only U.S. federal government agencies were allowed to register a .gov domain. In May 2002, GSA proposed a change that would open registration to state, local, and tribal governments in the U.S.,[15] a change that went into effect in March 2003.[16]
In November 2019, before the transfer of .gov to CISA, GSA's authorization process was shown to be weak after someone impersonated the mayor of Exeter, Rhode Island in an authorization letter and successfully gained control of exeterri.gov. In response, GSA said it had implemented additional fraud prevention controls, and CISA advocated for transferring the TLD from GSA.[17]
The DOTGOV Act requires that CISA maintain requirements that “minimize the risk of .gov internet domains whose names could mislead or confuse users”.[18] These include:
The Act also requires that .gov domains not be used for political campaign or commercial purposes, and that domains are registered only by authorized individuals.
.gov has been used to serve certain policy goals. As an action following Executive Order 13571,[20] President Barack Obama restricted executive branch agencies from registering new .gov domains in an attempt to eliminate unnecessary, redundant, or outdated sites.[21] US government agencies used the .gov registrar to make it easy for new registrants to opt-in to HTTPS preloading [22] and to make it easier for the public to report potential security issues.[23]

While the use of gov as a top-level domain is restricted to the United States, several other countries have second-level domains of the same name or similar semantics for governmental purposes, including the following. Note that the governments of some jurisdictions use alternate domains in public communications (for example, the Government of Canada adopted canada.ca as its main public-facing URL in the 2010s, and some Canadian provinces have made similar changes).
