Domain requirements FAQ
Who can obtain a .gov domain and what are the requirements?
Only U.S.-based government and public sector organizations are eligible to obtain a .gov domain. This includes any federal, state, local, or territorial government entity, or other publicly controlled entity. It also includes any tribal government recognized by the federal government or a state government. Eligibility is determined by the DotGov Program, which will be informed by the United States Census Bureau’s criteria for classifying governments.
The requirements specify the general requirements that all domain registrants need to follow, as well as the specific requirements for the different domain types, or kinds of government organizations. The specific requirements outline additional requirements (where applicable), but the key detail is that they describe who your “authorizing authority” is, or the official we’ll accept as signatory for your .gov domain request.
What’s an “authorizing authority”, and who is ours?
The authorizing authority is the official we’ll accept as signatory for your .gov domain request. To determine who yours is, evaluate what kind of government organization yours is and follow the link:
- Federal: Federal agencies from all three branches of the federal government
- Native sovereign nation: Tribal governments recognized by the federal government or a state government
- State/U.S. territories: 50 U.S. states, District of Columbia (D.C.), American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and U.S. Virgin Islands
Interstate (multi-state) governmental organizations are most frequently formed via legislation from Congress or from a legal accord between, or passed by, the state governments of two or more states. Examples include multi-state commissions, organizations that manage interstate compacts, or port authorities that operate across jurisdictions.
- Independent intrastate:
Independent intrastate (within a single state) governmental organizations are most frequently formed via state or local legislation, where authority is vested in them to operate fully or quasi-independently from the state. Examples include organizations authorized by law that operate a jurisdiction’s elections, manage regional transit, or do area-wide economic planning with governance independent from e.g., the executive branch.”
- City/County: Cities, towns, villages, counties, parishes, borough, or equivalents
What contact information do we need to keep updated?
Domain name registrants must keep names, email addresses, and phone numbers current for administrative and technical contacts. In general:
An administrative contact is the person who controls or approves content on the domain and is the manager of operations for the domain.
A technical contact is the person who directly manages or operates your DNS.
Administrative and technical contacts have accounts to the .gov registrar and can make changes to your DNS nameservers.
(A legacy contact, the billing contact, remains, even though domains are now available at no cost. You may consider it a secondary administrative contact.)
A security contact is a recommended practice. It should be added to allow the public to report observed or suspected security issues at your domain. Security contact details are made public. We recommend using an alias, like
At present, we don’t allow a single person to serve as more than one contact – even for the billing account - meaning that three distinct contacts are required. (This does not apply to security contact.)
How do I request an exception to the naming requirements?
My authorizing authority won’t sign an authorization letter. What do I do now?
Without a letter signed by the party defined in our domain requirements as the authorizing authority for your organization, you cannot register a .gov domain name.
Does the .gov TLD provide hosted DNS services for .gov domains?
No. We manage the authoritative name servers for the .gov zone, and ensure
.gov is propagated to the root name servers. We don’t operate a for-government, managed DNS hosting service.
Your internet service provider or technical support team can provide you with DNS name server addresses for your domain, which often take the form of
What are the name server requirements for .gov domains?
- You must provide at least one primary and secondary name server.
- You may not specify an IP address for your name servers unless they are child name servers of the domain you’re trying to register or update.
What are the valid characters for a domain name and how long can it be?
The only valid characters for a domain name are letters, numbers, and a hyphen. Other characters, including a space, are not permitted. Domain names may not begin or end with a hyphen.
A domain name may be up to 26 characters long, including the 4 characters used to identify the top-level domain (e.g.,
Where do I look for the authoritative .gov zone data?
The root servers (
[a-d].gov-servers.net) are the authoritative source of .gov information that is “live” on the internet.
Will I be notified if a change is made to my DNS information?
Yes. In response to recent incidents affecting other top-level domains, .gov domain contacts will receive a system-generated email when a change is made to their DNS in the .gov registrar.
The email will alert the contacts that a change was made to their DNS information and include instructions for mitigation should it be necessary.
How quickly will changes to my domain propagate throughout the internet?
Propagation depends on a variety of factors, such as caching and connectivity, but changes are usually effective within 24 hours.
If you’re planning to make critical changes to your name servers over the weekend, please contact us before 5 p.m. the Thursday before to ensure the information propagates during weekend hours.
When can I define my DS record?
You can define Delegation Signer (DS) records during registration or after the domain name is active. Before your DS records are published in the .gov zone, they will be tested and verified.
Why won’t my domain work after updating the registration with actual name servers?
Adding name servers to a reserved domain does not change its status from reserved to active if other requirements are pending. You can reserve a domain’s registration for up to 90 days, giving you time to submit all of the required information.
If the name server information is the only remaining information required for registration, it will take approximately 1 to 2 days after receipt of valid name server data for us to activate your domain. Expect an additional 1 to 2 days for the update to propagate across the internet.
Contact information FAQ
How do I change a contact for my domain?
A current contact should contact us to establish a new user account. If all contacts are unavailable (e.g., they’ve left the organization), the authorizing authority must sign a new authorization letter and assign new domain contacts.
Can one person serve as contacts on a single domain?
No. At present, we don’t allow a single person to serve as more than one contact – even for the billing account - meaning that three distinct contacts are required. (This does not apply to security contact.)
Can a person serve as a contact on multiple domains?
Renewals, transfers, and deletions FAQ
How long is a .gov domain registered for?
One year. (Domain contacts will receive several reminder emails before expiration.)
How do I delete my domain?
If you’d like to delete a domain name, contact us. Once completed, you should ask your DNS provider to remove your domain’s authoritative DNS nameservers.
Danger: once a domain is deleted, the registration process must be started again to obtain the domain. Be certain you want to delete a domain before contacting us!
How do I transfer my domain to a different agency?
To transfer ownership of a domain name from one federal agency to another agency, two letters must be submitted to us: one from the transferring agency and one from the receiving agency.
Whether transferring or receiving, start by copying and pasting the domain transfer letter template into a document editor. The letter from both agencies must be on official agency letterhead and signed by the respecting authorizing authority. Once prepared, each agency emails their authorization letter to firstname.lastname@example.org. After we receive and verify both letters, the registry will be updated to reflect the transfer.
What happens if I do not renew my domain name?
Failure to submit updated contact information does not result in the immediate termination of your domain. However, it may be placed in a hold status. When a domain name is held, it ceases resolving in DNS, making all services attached to the domain inaccessible by name resolution.
If you do not wish to renew, please contact us to delete your domain.
