When you purchase a web address, you will inevitably hear three terms that sound nearly identical: registry, registrar, and reseller. Because these words share the same linguistic root, many website owners assume they are interchangeable labels for the company that billed their credit card.
In reality, they perform three fundamentally different roles in the global domain ecosystem. Confusing them can leave you stranded when you need to transfer a domain, recover an expired web address, or resolve an urgent technical DNS error. In this guide, we break down who does what, how money and data flow between them, and how to identify exactly who holds custody of your domain name.
Quick comparison: registry vs registrar vs reseller
The domain industry operates on a tiered wholesale-to-retail model. Here is how the three entities compare side by side:
| Entity | Primary Role | Who They Sell To | Real-World Example |
|---|---|---|---|
| Registry | Maintains the master database for a specific top-level domain (TLD) and sets wholesale pricing rules. | Accredited registrars only (never the general public). | Verisign (.com), PIR (.org) |
| Registrar | Accredited commercial retailer that interfaces with registries to lease domains to end-users and manage customer accounts. | Consumers, businesses, and third-party resellers. | Namecheap, Cloudflare Registrar, Porkbun |
| Reseller | Third-party company that bundles domain registration through an upstream registrar partnership. | Website hosting clients, website builder subscribers. | Web hosts, design agencies, Squarespace, Wix |
What is a domain registrar?
A domain registrar is an organization accredited by ICANN (the Internet Corporation for Assigned Names and Numbers) to sell domain registrations to consumers and businesses.
Think of a registrar as a licensed retail dealership. When you visit a registrar website to buy a domain, they check availability against the central registry, process your credit card payment, collect required contact records, and establish your account credentials.
The registrar provides the customer portal where you manage your nameservers, configure DNS records, enable WHOIS privacy protection, and renew your annual lease.
What is a domain registry? The master record keeper
A domain registry is the authoritative organization responsible for operating and maintaining the central database of all domain names registered under a specific top-level domain extension.
Every top-level extension has exactly one designated registry operator. For example:
- Verisign: Operates the master registry for all .com and .net domains globally.
- Public Interest Registry (PIR): Operates the central registry for all .org domains.
- Nominet: Operates the national registry for the .uk country-code extension.
Registries do not sell directly to consumers. Instead, they operate root zone name servers, establish technical policies, and charge registrars a fixed wholesale fee (roughly $8 to $10 annually for .com) for every domain leased under their extension.
What is a domain reseller (and why support matters)
A domain reseller is a company that sells domain registrations without holding direct ICANN accreditation. Instead, the reseller forms a business partnership with an accredited registrar to register names on behalf of their customers.
Web hosting companies, website builders, and digital marketing agencies are the most common resellers. When you sign up for a web hosting plan that includes a free domain, the hosting company is almost always acting as a reseller for an upstream registrar like Tucows, Enom, or Wild West Domains.
ICANN’s role in domain management
The Internet Corporation for Assigned Names and Numbers (ICANN) is the non-profit coordinating body that oversees the entire global domain name system.
ICANN does not sell domain names and does not resolve individual billing disputes. Instead, it creates universal policies, accredits registrars, maintains technical standards, and ensures that every domain name resolves to one unique IP address worldwide. ICANN charges a small fee of $0.18 per domain year to fund these governance operations.
How a registration flows from you to the registry
When you register a domain, requests and funds pass through four distinct tiers:
1. Registrant
You (The Buyer)
Pays retail fee ($10 to $20)
2. Reseller (Optional)
Web Host / Builder
Passes order to registrar
3. Registrar
ICANN Accredited
Pays wholesale registry fee
4. Registry
Master Database
Updates global root zone
How to find out who manages your domain
If you registered your domain years ago and cannot remember which company holds the registration credentials, run a free diagnostic search on the DomainRecon WHOIS Lookup Tool:
- 1.Enter your web address: Type your domain name into the search input.
- 2.Locate the Registrar field: Look for the official Registrar and Registrar IANA ID lines.
- 3.Identify the reseller tag (if present): If your domain was purchased through a web host, the WHOIS record will frequently display a dedicated Reseller field naming the specific provider where your customer login lives.
Registrar vs hosting vs DNS provider: key differences
Do not confuse your domain registrar with your website hosting provider or DNS manager:
Domain Registrar
Manages the legal lease of your web address name. You pay them to keep the domain registered in your name.
Web Hosting Provider
Provides the physical or cloud server hardware where your website files, databases, and images live.
DNS Provider
Translates human-readable domain names into numerical server IP addresses so web browsers can connect to your host.
You can keep all three services at separate companies for maximum flexibility and security. To explore how domain registration and web servers interact in detail, read our foundational guide on Domain vs Hosting: What’s the Difference?.
Why it matters: transfers, security locks, and support
Knowing who manages your domain is essential for three practical reasons:
- Domain portability and transfers: If you want to move your domain to another provider with cheaper renewal rates, you must request an authorization code and unlock the name at your active registrar.
- Security locks: Direct accredited registrars provide robust two-factor authentication and registrar-level transfer locks that prevent unauthorized domain hijacking.
- Choosing the right provider: Selecting a transparent, developer-friendly registrar ensures you receive free WHOIS privacy and zero inflated renewal fees. To learn what to look for when picking a provider, see our guide on How to Choose a Domain Name.
Frequently asked questions & conclusion
Can I buy a domain directly from a registry?
No. Central registries do not operate retail consumer storefronts. You must register your domain through an accredited registrar or authorized reseller.
Can I switch registrars after buying a domain?
Yes, once ICANN standard initial 60-day transfer lock expires. After sixty days, you can transfer your domain to any accredited registrar you prefer.
What happens if my registrar goes out of business?
Your domain remains safe. Because ownership records are held at the central registry, ICANN will automatically reassign all domains from a failed registrar to another accredited provider.
Registries operate master directories, registrars sell retail leases, and resellers bundle domains with web services. Knowing the roles of each player gives you full command over your online identity and ensures you can manage, secure, and transfer your digital assets with confidence.
