What Is a Domain?

A domain name is the unique web address that people use to find and access a website on the internet. Instead of entering a complex numerical IP address, visitors can simply type a memorable domain name such as example.com into their browser. A domain acts as an easy-to-remember identity for a website and helps users reach the website or online service associated with it. Every domain consists of a name and a domain extension, such as .com, .org, .net, or country-specific extensions like .in. Domain names are registered through domain registrars and are generally leased for a specific period, after which they need to be renewed to keep ownership and control of the domain.

What Is WHOIS?

WHOIS is a service that provides information about a registered domain name, such as its registration status, registrar, registration and expiration dates, and certain contact or administrative details. It is commonly used to check whether a domain is already registered, identify the registrar managing it, and review important registration information. However, the amount of personal information publicly available through WHOIS can vary because of privacy regulations, registry policies, and domain privacy services. Today, many domain registration systems use RDAP (Registration Data Access Protocol) as the modern replacement for traditional WHOIS, although the term “WHOIS” is still widely used when referring to domain registration lookup services.

What Is ICANN?

ICANN, short for the Internet Corporation for Assigned Names and Numbers, is a global nonprofit organization that coordinates key parts of the Internet’s unique identifier systems, including the Domain Name System (DNS). ICANN helps coordinate the domain name system so that domain names remain unique and can reliably direct users to the intended online destination. It also develops and coordinates policies for generic top-level domains (gTLDs) and accredits domain registrars that provide registration services.

When you register a domain such as example.com, you normally do not register it directly with ICANN. Instead, you use a domain registrar or an authorized reseller. The registrar operates under agreements and policies within the domain name registration system, while the relevant registry manages the database for a particular TLD. ICANN therefore plays a coordination and policy role in the domain ecosystem rather than acting as a retail domain provider.

It is also important to understand what ICANN does not do. ICANN does not sell domains directly to the public, provide web hosting, or control the content published on websites. Its role is primarily focused on maintaining the stability, security, and interoperability of the Internet's unique identifier systems.

What Is a Domain Registrar?

A domain registrar is a company or organization that provides domain name registration services, allowing individuals and businesses to register, manage, renew, and transfer domain names. When you purchase a domain such as example.com, you typically buy it through a registrar rather than directly from ICANN. The registrar communicates with the relevant domain registry to register the domain in your name and provides a management interface where you can manage settings such as DNS records, nameservers, renewal, and domain transfers. Registrars may also offer additional services such as WHOIS privacy or domain privacy, email services, SSL certificates, and web hosting. Different registrars can offer different prices, renewal rates, features, support options, and promotional discounts, so it is important to check both the first-year price and the regular renewal price before registering a domain.

What Is a Domain Reseller?

A domain reseller is an individual, business, or company that sells domain registration services to customers using the infrastructure and services of an established domain registrar or registry provider. Unlike an accredited registrar, a reseller generally does not maintain the domain registry itself. Instead, it operates through a registrar or reseller platform that handles the underlying domain registration process. The reseller may provide its own website, pricing, customer support, branding, and additional services while the upstream registrar manages the technical registration relationship with the domain registry. This allows businesses such as web hosting companies, agencies, and IT service providers to offer domain registration without becoming an accredited registrar themselves. When purchasing a domain from a reseller, it is therefore useful to check who the underlying registrar is, who controls the domain account, and what policies apply to renewal, transfer, expiration, and domain management.

How to Identify Whether a Domain Provider Is a Registrar or Reseller

The easiest way to distinguish a domain registrar from a domain reseller is to check whether the company itself appears in ICANN's official list of accredited registrars. An ICANN-accredited registrar has a direct accreditation relationship with ICANN for applicable generic top-level domains (gTLDs), while a reseller sells domain registration services through an accredited registrar and is not itself accredited by ICANN.

However, simply seeing a company selling domains does not tell you whether it is a registrar or reseller. A company can have its own website, pricing, customer dashboard, support team, and domain-management features while still operating as a reseller. The practical way to verify it is to search the company's name in ICANN's Accredited Registrar Directory. If the company appears there as an accredited registrar, it is an ICANN-accredited registrar for the relevant gTLD services. If it does not appear there, it may be a reseller or another type of domain service provider. For an already registered domain, you can also use ICANN's lookup service or registration data to identify the sponsoring registrar; where available, registration data may separately show a Reseller field.

Registrar vs Reseller: How to Tell the Difference

The important point is that a reseller is not necessarily an unreliable or unofficial domain seller. Resellers are a recognized part of the domain registration system, and ICANN requires accredited registrars to have agreements with their resellers and remain responsible for registrar services provided through them.

How to Check a Provider Before Buying a Domain

Before purchasing a domain, you can follow these steps:

1. Search the provider's name in ICANN's accredited registrar directory. If it is listed, check the exact legal/company name and IANA number rather than relying only on the brand name.

2. If it is not listed, don't automatically assume it is unauthorized. It may be operating as a reseller of an accredited registrar.

3. Ask the provider which registrar it uses if this information is not clearly disclosed.

4. For an existing domain, check the domain's registration data to identify the sponsoring registrar and, where available, the reseller.

5. Check who controls the domain account and transfer process, especially before purchasing a domain for a business.

One important limitation is that ICANN accreditation applies to gTLDs such as .com, .net, and .org; country-code domains such as .in are governed by their respective ccTLD operators and may follow different accreditation and registration structures.

Domain Registration Offers & Coupon Codes

The table below lists domain registration providers and promotional offers identified through research conducted on 10 September 2026. Prices, coupon codes, eligibility requirements, and promotional terms can change at any time, so the information shown should be treated as a snapshot of the offers available at the time of research. Before purchasing a domain, readers should verify the coupon code, final checkout price, applicable TLD, and offer conditions directly with the provider, as the current price or availability may differ.

What Is Domain Registration, Renewal, and Transfer?

Domain registration, renewal, and transfer are three different processes involved in managing a domain name. Understanding the difference is important before purchasing a domain because the price and rules for each process can vary between domain providers and domain extensions.

Domain Registration

Domain registration is the process of registering an available domain name for a specific period, usually one or more years. When you register a domain, you choose an available name and pay the applicable registration fee through a registrar or reseller. Once the registration is completed, the domain is added to the relevant domain registry and you receive control over the domain through your registrar account. A domain registration does not mean that you permanently own the domain; instead, you have the right to use and manage it for the registered period, subject to the applicable registry and registrar policies.

Domain Renewal

Domain renewal is the process of extending a domain's registration period before it expires. For example, if a domain is registered for one year, renewing it can extend the registration for another year. Renewal prices are often different from promotional first-year registration prices, which is why you should check the regular renewal price before choosing a domain provider. If a domain is not renewed on time, it can enter different post-expiration stages depending on the TLD and applicable registrar and registry policies, potentially resulting in additional fees or the eventual deletion of the domain.

Domain Transfer

Domain transfer is the process of moving a domain from one registrar to another while keeping the same domain name. A transfer does not normally mean registering a completely new domain; instead, the domain's registrar is changed. Depending on the TLD and circumstances, the transfer may require authorization or other security checks, and certain transfer restrictions can apply. Before transferring a domain, it is important to check the eligibility requirements, transfer fee, expiration status, and any applicable transfer lock or waiting period.
