What is a domain registrar?
A domain registrar is an organization accredited by ICANN (or a national ccTLD authority) to sell domain name registrations to the public. Registrars act as intermediaries between domain registrants (you) and domain registries (organizations that manage TLD databases).
How registrars work
The domain registration chain:
Registrant (you)
↓ Purchase domain
Registrar (GoDaddy, Namecheap, Cloudflare, etc.)
↓ Submit registration to
Registry (Verisign for .com, Public Interest Registry for .org, etc.)
↓ Update
Root DNS / TLD Zone
Registrars don't control the TLD databases. They have authorized access to add, modify, and renew domain registrations through the registry.

Registrar accreditation
ICANN accreditation (gTLDs)
To sell .com, .net, .org and other gTLDs, registrars must:
- Apply to ICANN
- Meet technical and financial requirements
- Sign the Registrar Accreditation Agreement
- Pay accreditation fees
ccTLD authorization
Each country's TLD authority sets its own registrar requirements. Some ccTLDs allow any ICANN-accredited registrar; others require separate authorization.
Choosing a registrar
Pricing considerations
- Registration price: First-year cost (often discounted)
- Renewal price: Ongoing annual cost (may be higher)
- Transfer price: Cost to move from another registrar
- Add-ons: WHOIS privacy, email, SSL (often free elsewhere)
Features to compare
- WHOIS privacy: Redacts your personal info from public WHOIS
- DNS management: Quality of DNS hosting interface
- API access: For programmatic domain management
- Two-factor auth: Account security options
- Transfer lock: Prevent unauthorized transfers
- Auto-renewal: Avoid accidental domain expiration
Red flags
- Expensive WHOIS privacy (should be free)
- High renewal prices hidden behind low first-year pricing
- Aggressive upselling
- Difficult transfer-out processes
- Poor customer support

Registrar vs registry
| Aspect | Registrar | Registry |
|---|---|---|
| Role | Sells domains | Manages TLD database |
| Customer | End users (you) | Registrars |
| Examples | Namecheap, Cloudflare | Verisign, PIR |
| Relationship | Many per TLD | One per TLD |
Domain registrar APIs
For developers automating domain management:
// Example: Checking availability via registrar API
const response = await fetch('https://api.registrar.com/domains/check', {
method: 'POST',
body: JSON.stringify({ domain: 'example.com' })
});
Many registrars offer APIs for:
- Availability checking
- Registration
- DNS management
- Renewal
- Transfers
However, for availability checking alone, purpose-built APIs like DomScan often provide better performance and features.
