Domain name registry: what it is and how registrars fit in

Verisign manages the .com registry and the .net registry; the Public Interest Registry manages .org. Buyers do not interact with registries directly; they purchase through ICANN-accredited registrars. This guide explains why that structure exists and what it means when you register a domain name.

What is a domain name registry?

A domain registry is the authoritative backend operator for a top-level domain. It maintains the zone file that maps every registered domain name under that TLD to its nameservers, and enforces the technical and policy rules for who can register domains under that extension. For every TLD, .com, .org, .io, .co, there is exactly one registry.

The registry is not the company you buy a domain from. That distinction is the most common source of confusion in the domain name system (DNS). The registry sits one layer behind the transaction:

• Registry: the organization that runs the TLD database and sets the rules.
• Registrar: the ICANN-accredited company you buy a domain name from.
• Registrant: you, the domain owner.

What does a domain registry do?

A registry performs three core functions. Each one has a practical consequence for domain buyers.

The wholesale pricing function has the biggest practical consequence for buyers. When Verisign sets the wholesale rate for a .com domain, that rate is the floor every registrar pays. Above that floor, each registrar sets its own retail price, including the renewal rate, which is the price you pay from year two onward. Checking renewal prices before committing to a registrar is the single most useful thing the registry-registrar structure teaches buyers.

The difference with a domain registrar

The registry is the wholesale database operator. The registrar is the ICANN-accredited retailer that purchases access from the registry at wholesale rates and handles domain name registration for buyers. Think of the registry as a wholesale distributor that only sells to approved retailers; you can't walk into the warehouse. The registrar is the store.

Because registrars set their own retail prices on top of the registry wholesale rate, the same .com domain can cost significantly different amounts depending on where you register it, especially at renewal. A registrar offering a first-year .com for $1.99 may charge $18.99 for renewal from year two. Another registrar may charge $10.98 for both registration and renewal. Both registrars access the same Verisign registry and deliver exactly the same underlying domain. The difference is entirely in the registrar's margin.

This is why comparing registrar prices matters, and why comparing renewal rates matters more than comparing registration rates. TLD-list tracks registration, renewal, and transfer prices across 100+ registrars so you can see the real multi-year cost before you commit.

Who are the main domain registries?

The registry landscape is divided between legacy TLDs managed by the same organizations for decades, and new gTLDs introduced after ICANN's 2012 expansion program. Here are the major registries:

The identity of the registry matters when you register a domain because it determines the rules and wholesale pricing that all registrars must pass through. For gTLDs like .com and .net, Verisign's ICANN contract includes price caps that limit how much the wholesale rate can increase year-over-year. For newer gTLDs with fewer restrictions, registry pricing changes can affect renewal costs for all domains under that TLD regardless of which registrar you used.

How ICANN connects registries and registrars

ICANN (the Internet Corporation for Assigned Names and Numbers) is the nonprofit that coordinates the global domain name system. It does not sell domain names. Its role is to set the framework that makes the registry-registrar system work globally.

ICANN connects the two layers through contracts:

• Registry agreements, ICANN contracts with each registry to authorize it to operate a specific TLD. These contracts govern wholesale pricing caps, WHOIS data requirements, and technical standards for zone file management.
• Registrar Accreditation Agreements (RAA), ICANN accredits registrars to access registry databases and sell domain registrations to the public. Accreditation requires meeting minimum technical, financial, and policy standards.

ICANN also enforces shared policies across both layers, including WHOIS data collection and maintenance, domain transfer process policies (the reason transfers between registrars are possible at all), and dispute resolution through the Uniform Domain-Name Dispute-Resolution Policy (UDRP). For buyers, ICANN accreditation is what distinguishes a legitimate registrar from an unaccredited reseller.

What the registry-registrar system means for domain buyers

The registry-registrar structure has four practical consequences for anyone registering a domain name.

You always buy from a registrar, not a registry. No buyer can register directly with Verisign or PIR. ICANN only accredits registrars to interact with registries on buyers' behalf.

The registry sets the floor; the registrar sets the retail price. The same .com domain can cost between $8 and $18 per year at different registrars because each adds its own margin on top of the same Verisign wholesale rate. You are getting the same domain either way; only the registrar's pricing and services differ.

Renewal prices can differ from registration prices. Many registrars offer promotional first-year pricing; the renewal rate is often higher. Always check the renewal price, not just the registration price, before choosing a registrar. A domain that costs $2.99 to register for the first year and $24.99 to renew will cost more over three years than one priced at $12.99 for both.

The registry controls what happens to a TLD long-term. If a registry changes its pricing policy, updates its eligibility rules, or is acquired by another company, that affects all domains registered under that TLD, regardless of which registrar you used.
