What is a domain registry vs registrar vs reseller?

If you’ve ever registered a domain name, you’ve interacted with a surprisingly complex ecosystem.

The topic of domain registry vs registrar is one of the most common sources of confusion in the domain industry, especially for beginners. Add resellers into the mix, and it can feel even harder to understand who actually does what.

In this article, we’ll explain how the domain ecosystem works, clarify the difference between registry, registrar, and reseller, and show where Openprovider fits within the system.

How domain registration works

Every domain name follows a standard domain registration process. ICANN, the Internet Corporation for Assigned Names and Numbers, is the global body responsible for coordinating how domain names and IP addresses are managed across the internet.

When someone registers a domain, several parties are involved in the background. The registrar checks whether the domain is available by querying the relevant registry. If it is, the registrar provisions the domain and adds it to the global DNS. From that point on, the domain becomes active and can be configured using DNS management tools, renewed each year, transferred between providers, or updated when ownership changes.

This entire flow is part of the domain ownership lifecycle, which includes registration, active use, renewal, transfer, possible expiration, and eventually deletion if the domain is not renewed.

What is a domain registry?

A domain registry is the organization that owns and operates a top-level domain. This means the registry is responsible for everything that happens at the TLD level, such as maintaining the authoritative database of registered domains and running the DNS infrastructure that makes those domains resolvable on the internet.

For example, Verisign operates the .com and .net registries, while other companies manage extensions like .shop, .tech, or country-code TLDs such as .nl or .de. Each TLD has exactly one registry operator.

Registries do not interact with end users. Instead, they work exclusively with registrars and provide the technical systems that allow domains to be created, updated, transferred, and deleted. They also define the rules and policies for their TLD, including registration requirements, pricing models, and lifecycle processes.

What is a domain registrar?

A domain registrar is a company authorized to sell domain names to customers. Registrars sit directly between registries and end users and handle everything related to the commercial side of domain registration.

This includes selling and renewing domains, managing customer accounts, providing DNS management tools, and supporting domain transfers and ownership changes. When you buy a domain from a registrar, you are entering into a retail relationship with that company, even though the domain itself is ultimately recorded in the registry’s database.

Registrars typically purchase domains from registries at wholesale prices and sell them to customers at retail prices. This is where the concept of wholesale vs retail domain pricing comes in. Most registrars add their own margins on top of the base registry fees – although some, like Openprovider, offer access to wholesale pricing for domains via convenient subscription plans.

Requirements for ICANN-accredited domain name registrars

To operate as a registrar, a company must be accredited by ICANN. This accreditation process is strict and requires meeting a range of technical, financial, and operational standards.

Registrars must apply directly to ICANN, pay accreditation fees, demonstrate secure technical systems, and comply with ICANN policies related to data protection, DNS stability, and customer rights. They also need to maintain contractual relationships with each registry they want to offer.

While accreditation provides direct access to registries, it also comes with significant complexity, costs, and ongoing compliance obligations. This is one of the main reasons many businesses choose not to become registrars themselves.

What is a domain reseller?

A domain reseller is a company that sells domain names without being accredited for them directly. Instead of connecting directly to registries, resellers use a registrar to offer domain services to their customers.

From a customer perspective, a reseller often looks exactly like a registrar. They may have their own branding, pricing, customer support, and management interface. The difference lies entirely in the underlying infrastructure and accreditation.

Resellers typically focus on serving specific markets such as small businesses, freelancers, agencies, hosting providers, SaaS platforms, or IT service companies. They use APIs and white-label platforms to automate domain provisioning, manage large portfolios, and integrate domain services into their own products.

This model allows companies to offer domains without having to build and maintain complex registry integrations or deal with ICANN compliance.

Domain registry vs registrar vs reseller

Understanding the difference between registry and registrar is key to understanding how the domain ecosystem works as a whole. Adding resellers completes the picture.

This is how it works:

The registry operates the TLD and maintains the authoritative database.
The registrar sells domains to customers and manages the commercial relationship.
The reseller builds domain services on top of that infrastructure and focuses on customer experience, integrations, and portfolio management.

In practical terms, registries run the extensions, registrars sell domains, and resellers package domain services for businesses.

Why registrars are important for businesses and agencies

For most businesses with larger domain portfolios, especially digital agencies and SaaS companies, managing these domains is not a part of their core business. What they need is a reliable and scalable way to handle domain registration, DNS management, and domain transfers for many customers or brands.

Reseller platforms fill this gap by providing the infrastructure layer that connects business systems to the global domain ecosystem. Instead of dealing with dozens of registries and complex technical standards, companies can manage everything through a single interface.

This makes it possible for them to automate the domain registration process, handle bulk domain management, streamline domain transfer workflows, and centralise billing and reporting across large portfolios.

In other words, registrars translate a highly technical system into something that fits real business workflows.

Where Openprovider fits

Openprovider is an ICANN-accredited registrar built specifically for resellers. Our platform connects resellers directly to hundreds of registries through a single interface. For thousands of hosting companies, marketing agencies, and IT service providers, Openprovider acts as the infrastructure layer that simplifies their domain operations.

Openprovider provides access to over 1,900 TLDs through one platform, with wholesale domain pricing, an API to automate domain provisioning, and advanced bulk domain management tools. This allows resellers to build domain services into their own platforms without needing to deal with registry accreditations and the high amount of legal, technical, and admin work that come with them.

Our model stands out from other registrars in one important way. The Membership model gives resellers access to wholesale pricing on domains. This means that you pay exactly the same cost we pay at the registries, without any markup or tiers you need to hit.

Security and transparency are also core to how we operate – from using AI and working with non-profits to tackle abusive domains, to being ISO 27001 and NIS2 compliant.

And lastly, our customers are at the heart of everything we do, with 24/7 support, a personal account manager for every reseller, and a monthly thought leadership newsletter on how to grow your business with domains (sign up at the bottom of this article).

These reasons explain why customers see Openprovider as an affordable, trusted digital infrastructure company.

Conclusion

The domain ecosystem becomes much easier to understand once you separate the roles. Registries operate top-level domains, registrars sell domains to customers, and resellers build business services on top of that foundation.

The real difference between registry and registrar is ownership versus distribution. Resellers then bridge the gap between technical infrastructure and real-world business needs.

For companies that manage domains at scale, the reseller model offers a flexible and efficient way to operate in the domain market. And with a reseller-first platform like Openprovider, domain management becomes a streamlined part of your business instead of a separate operational challenge.
