Check a domain expiration date before renewal, transfer, or account-owner follow-up so the next action is tied to the registry record instead of memory or billing assumptions. Capture the registry expiry timestamp, not a date copied from a disclaimer, registrar promotion, or unrelated account notice.
Legacy WHOIS is free-form text. A gTLD record may expose Registry Expiry Date from the registry server, while a default client may stop at an IANA or registrar referral that has no expiration field.
RDAP returns the same lifecycle data as structured JSON and is the authoritative registration-data surface for gTLDs after the WHOIS sunset. Treat both sources as public registration evidence only, because registrar account billing state, auto-renew settings, holds, and grace periods still need account confirmation before a renewal or transfer decision.

$ whois example.com % IANA WHOIS server % for more information on IANA, visit http://www.iana.org % This query returned 1 object domain: EXAMPLE.COM organisation: Internet Assigned Numbers Authority created: 1992-01-01 source: IANA
If the answer has no expiry label and only points to a registry, registrar, or TLD record, query the referred WHOIS server next.
$ whois -h whois.verisign-grs.com example.com Domain Name: EXAMPLE.COM ##### snipped ##### Registry Expiry Date: 2026-08-13T04:00:00Z Registrar: RESERVED-Internet Assigned Numbers Authority ##### snipped #####
Use the server that matches the TLD or referral output. The whois.verisign-grs.com server is for .com and .net registry records, not every domain.

Registry Expiry Date: 2026-08-13T04:00:00Z
Other records may use labels such as Expiration Date, Registry Expiration, Expiry Date, or paid-till depending on the registry.
Domain Status: clientDeleteProhibited https://icann.org/epp#clientDeleteProhibited Domain Status: clientTransferProhibited https://icann.org/epp#clientTransferProhibited Domain Status: clientUpdateProhibited https://icann.org/epp#clientUpdateProhibited
Status codes do not extend registration. Holds, redemption, pending delete, or transfer restrictions can change the renewal or transfer action tied to the expiry date.
$ curl -fsSL https://rdap.org/domain/example.com | jq '.events[] | select(.eventAction == "expiration")'
{
"eventAction": "expiration",
"eventDate": "2026-08-13T04:00:00Z"
}
Use RDAP as the structured fallback for lifecycle dates, status values, nameservers, and registrar entities.

The success state is the public expiry timestamp, the source that supplied it, any status-code caveat, and a note that registrar-account confirmation is still required.
