The date when a domain registration ends and must be renewed to remain active.
Expiration dates are recorded in WHOIS. After expiration, domains enter grace and redemption periods before becoming available for registration by others. Missing renewal can result in domain loss.
Exampleexample.com expires: 2025-06-15
A period after expiration (typically 30-45 days) during which the owner can still renew at normal rates.
During grace period, the domain may stop resolving but remains registered to the original owner. Renewal is straightforward and inexpensive. After grace period ends, redemption begins.
Example30-day grace period after expiration date
A period after grace (typically 30 days) where recovery requires expensive redemption fees.
Redemption fees typically range $100-200+ plus renewal cost. The domain is held in "pending delete" status. Only the original registrant can recover it. After redemption, domains enter pending delete before release.
Example$150 redemption fee + $15 renewal = $165 recovery cost
When an expired domain becomes available for registration by the public.
After expiration, grace, and redemption periods end, domains are deleted and released. High-value domains are often caught by backorder services instantly. Drop-catching is competitive for desirable names.
ExampleDomain drops after ~75 days post-expiration
A protocol and database system providing information about domain registration.
WHOIS records include registration, expiration, and update dates, plus registrar and (depending on privacy settings) registrant contact information. WHOIS is the primary source for domain expiration data.

A company authorized to register domain names on behalf of customers.
Registrars are accredited by ICANN (for gTLDs) or country-code authorities. They manage domain registration, renewal, and DNS settings. Popular registrars include GoDaddy, Namecheap, Google Domains, and Cloudflare.
ExampleNamecheap, GoDaddy, Cloudflare Registrar
A service that attempts to register a domain the moment it drops.
Backorder services monitor expiring domains and submit registration requests as soon as they're released. Multiple parties may backorder the same domain, leading to auctions. Success rates vary by domain value and competition.
