A domain backorder is a paid request placed with a registrar or third-party drop-catching service to automatically register a domain name the instant it becomes available after expiration. When a domain expires, it enters a grace period and then a pendingDelete state before being released back into general availability—a moment known as the "drop." Backorder services monitor domains approaching this release and use automated, high-speed registration systems to submit registration requests the second the name becomes available.
The domain lifecycle that makes backordering possible is governed by standards like RFC 5731 (EPP Domain Name Mapping) and RFC 3915 (the Redemption Grace Period). ICANN's Expired Registration Recovery Policy requires registrars to notify domain owners of expiration and provide recovery windows before final deletion. After those windows close, the domain drops.
Backorder providers typically operate an auction system: if multiple customers want the same dropped domain, the service conducts an auction among them for the right to register it. When the backorder succeeds, the customer gains control of the domain; if it fails (another registrant or backorder service registered it faster), the fee is usually refunded.
WarningBackorder success is never guaranteed. Multiple services compete on speed and registry access, and a faster competitor may catch the domain first. Many dropped domains never reach the backorder stage because the original owner renews it during the grace period.
Backordering is common for reclaiming a previously owned domain, acquiring an abandoned brand name, or buying domains in high demand at a lower cost than purchasing from a current owner. Most major registrars offer backorder services, and specialty drop-catching companies exist for high-value drops.
