Registry, registrar, registrant — three near-identical words that describe three completely different roles in how domain names work. They are easy to mix up, yet they sit at the heart of who runs the domain system, who you buy from, and who actually owns a domain. Understanding them turns a confusing tangle of jargon into a simple, logical chain that makes the whole domain world make sense.
This guide defines each of the three clearly, shows how they relate in a straightforward hierarchy, explains where ICANN and resellers fit in, and shows why the distinction matters to you as a domain owner. With a simple wholesaler-retailer-customer analogy, you will never confuse these terms again.
Did you know?
The three R’s map neatly onto shopping: the registry is the wholesaler that stocks an entire product line, the registrar is the shop that sells it to the public, and the registrant is you, the customer walking out with the goods.
The three roles at a glance
In one sentence: a registry manages a top-level domain extension, a registrar sells and manages domain names to the public, and a registrant is the person or company that buys and holds a domain. Each operates at a different level of the system, and together they make it possible for you to register and use a web address.
The relationship is a chain. The registry sits at the top, running the infrastructure for an extension like .com. The registrar sits in the middle, retailing individual names from that extension. And the registrant — you — sits at the end, owning and using a specific name. Value and control flow down the chain from the registry to the registrar to you.
The easiest way to remember it is the wholesaler-retailer-customer analogy, which maps perfectly onto the three roles. Once you see that mapping, the jargon dissolves into common sense.
The registry: the wholesaler
A registry is the organisation that manages a specific top-level domain extension — for example, Verisign runs .com. The registry maintains the master database and the technical infrastructure for that extension, keeping the authoritative record of every domain registered under it and ensuring the whole thing runs reliably. It also sets the rules and the wholesale pricing for its extension.
Crucially, a registry does not sell domains directly to the public. It operates at the wholesale level, working with registrars rather than individual customers. When you register a .com, the registry is the entity that ultimately records it in the master database, but you never interact with it directly — that is the registrar’s job.
So the registry is the wholesaler of the domain world: it owns and runs the product line (an extension), maintains the central records, and sets the terms, but leaves the actual selling to others. Each extension has its own registry, which is why rules and prices can differ between, say, .com and a newer extension.
The registrar: the retailer
A registrar is an accredited company that handles the commercial sale and management of domain names — the public-facing store where you actually buy a domain. Examples include the well-known companies people register names through every day. When you search for a name, pay for it, and manage it afterwards, you are dealing with a registrar.
The registrar’s job is to process your purchase and register the domain with the appropriate registry on your behalf, then give you the tools to manage it: renewals, DNS settings, privacy, and security. To do this, it must be accredited by ICANN, which ensures it follows the rules and can be trusted to record ownership correctly.
So the registrar is the retailer: it buys access at the wholesale level from registries, sells individual domains to the public, and provides the customer-facing experience. This is the company you choose, pay, and manage your domain through — which is why picking a good registrar, with fair renewal pricing and solid support, genuinely matters.
The registrant: the customer and owner
The registrant is the individual or business that registers and holds the rights to use a domain name — in other words, you, the owner. When you register a domain, your details are recorded as the registrant, establishing you as the party who controls it. You decide where it points, what website and email it serves, and whether to renew, transfer, or sell it.
As the registrant, your control flows through your registrar’s dashboard, but the rights to the domain belong to you. It is worth remembering that a registrant does not own the domain permanently — like everyone, you hold a renewable right to use it for a term — but you are the recognised owner for as long as you keep the registration active.
So the registrant is the customer: the person who walks away with the domain and uses it. Protecting your position as registrant — by renewing on time, securing your account, and keeping your details accurate — is what keeps the domain reliably yours.
Where ICANN and resellers fit in
Above all three roles sits ICANN — the Internet Corporation for Assigned Names and Numbers — which oversees the entire domain system. ICANN sets the overarching rules, accredits registrars, and coordinates the registries, ensuring the whole system stays consistent, fair, and reliable worldwide. It does not sell domains or run individual extensions itself; it is the coordinating authority above the chain.
There is also sometimes a fourth layer: the reseller. A reseller sells domains through a registrar’s infrastructure without being a fully accredited registrar itself — for example, a web design agency or hosting company that offers domains via a partnership. To you as the customer, a reseller looks much like a registrar, but the domain is ultimately registered through the accredited registrar behind it.
So the full picture is: ICANN oversees the system; registries wholesale each extension; registrars (and sometimes resellers) retail individual names; and registrants own and use them. Every domain in the world fits into this structure.
Why the distinction matters to you
This is not just terminology — it explains several practical realities. It is why you cannot register a domain directly with a registry and must go through a registrar: the roles are deliberately separated. It is why the registrar you choose matters, since that is the company handling your purchase, renewals, and support. And it is why you, as registrant, are the one responsible for renewing and securing the domain.
Understanding the chain also helps when things get complicated. If there is ever a dispute over a domain, knowing who the registry, registrar, and registrant are tells you who does what. If you transfer a domain, you are moving it between registrars while remaining the registrant. And if you buy through a reseller, you understand who is ultimately behind your registration.
In short, knowing the three R’s makes you a more informed domain owner. You know who you are dealing with at each step, who controls what, and where your own rights and responsibilities sit in the system.
Deal with one trusted registrar — and skip the confusion.

The three R’s side by side
To lock it in, here is the chain summarised. The registry (wholesaler) runs an extension like .com, maintains its master records, and sets its rules and wholesale pricing, but does not sell to the public. The registrar (retailer) is the accredited company you buy from, which registers your name with the registry and gives you tools to manage it. The registrant (customer) is you, the owner who registers and uses the domain.
Read the table top to bottom and you have the whole system: an authority overseeing wholesalers who supply retailers who sell to customers. That is the domain world in four rows — and now the three near-identical words are three clearly different things.
Frequently Asked Questions
What is the difference between a registry, registrar, and registrant?
A registry manages a top-level extension (like Verisign for .com) and its master records but doesn’t sell to the public. A registrar is the accredited retailer you buy and manage domains from. A registrant is you — the person or business that owns and uses a specific domain. It’s a wholesaler-retailer-customer chain.
Is a company like GoDaddy a registry or a registrar?
A public-facing domain seller is a registrar — the accredited retailer where you buy and manage domains. A registry is different: it’s the wholesale organisation running a whole extension (like Verisign for .com) and doesn’t sell to the public. You always buy from a registrar, not a registry.
Why must a domain be registered through a registrar?
Because registries deliberately operate at the wholesale level and don’t sell to the public. The system separates the roles: registrars are accredited by ICANN to handle the commercial side — taking orders, recording ownership, and providing management tools — and register your name with the registry on your behalf.
Who actually owns a domain name?
The registrant — the individual or business named on the registration — holds the rights to the domain and controls it. Strictly, no one owns a domain permanently; the registrant has a renewable right to use it. The registry and registrar run the system and the sale, but the registrant is the owner.
What is ICANN’s role?
ICANN (the Internet Corporation for Assigned Names and Numbers) oversees the whole domain system. It sets the rules, accredits registrars, and coordinates registries so the system stays consistent and fair worldwide. It doesn’t sell domains or run individual extensions itself — it’s the coordinating authority above the chain.
Does it matter which registrar I use?
Yes. Every registrar sells similar domains, but they differ in renewal pricing, included features like free privacy, dashboard quality, and support. Since you’ll renew and manage the domain there for years, choosing a reliable registrar with fair renewals — ideally one that also hosts your site — makes a real difference.
The bottom line
Registry, registrar, and registrant are three distinct roles in a simple chain. The registry is the wholesaler that manages a top-level extension like .com — running its master database and setting its rules, but not selling to the public. The registrar is the accredited retailer where you actually buy and manage domains, registering your name with the registry on your behalf. And the registrant is you, the customer who owns and uses the domain. Above them all, ICANN oversees the system, and resellers sometimes act as a fourth, front-end layer.
The wholesaler-retailer-customer analogy makes the whole thing click, and understanding it has real payoffs: it explains why you buy through a registrar, why choosing a good one matters, and where your own rights as registrant sit. Know the three R’s and the domain system stops being a tangle of jargon and becomes a clear, logical structure you can navigate with confidence.
