How to Monitor Domain Expiration: WHOIS, RDAP & Renewal Alerts

How to check any domain's expiry date

Three options, fastest first. Your registrar panel is authoritative for your own domains; WHOIS/RDAP work for any domain:

whois example.com | grep -i -E "expir|registrar:|status:"
# Registry Expiry Date: 2027-08-13T04:00:00Z
# Registrar: Example Registrar, Inc.
# Domain Status: clientTransferProhibited

curl -s https://rdap.org/domain/example.com | python3 -c "import json,sys; d=json.load(sys.stdin); print([e for e in d.get('events',[]) if e.get('eventAction')=='expiration'])"

Caveats: GDPR redaction and thin registries (like .com/.net historically) mean WHOIS output varies by TLD; some ccTLDs rate-limit or block bulk queries entirely. A monitor that normalizes RDAP first and falls back to WHOIS handles this for you.

What actually happens after expiry

• Grace period (~0–45 days): services stop, but you can still renew at the normal price. Length and even existence vary by registrar and TLD — never rely on it.
• Redemption period (~30 days): restore is possible but carries a steep restore fee (often $100+). Status shows as redemptionPeriod.
• Pending delete (~5 days) → release: first-come, first-served. Drop-catch services and squatters watch valuable names.

Why domains really lapse (it's never the date)

Almost no domain is lost because someone didn't know dates exist. The real causes: renewal notices going to a departed employee's inbox, an expired card on file with auto-renew silently failing, a reseller account nobody can log into, or a portfolio inherited in an acquisition. Good monitoring fixes the process failure, not just the date: alerts must reach a shared channel (Slack, PagerDuty, team email) — never one person's inbox.

Automate it in minutes

Weekly registration checks with reminders at 60, 30, 14, 7, and 1 days cover every realistic recovery path, including slow procurement and inter-registrar transfers (which can take a week and are blocked close to expiry). If the stakes are unclear, read what happens when a domain expires. Pair it with certificate expiry monitoring — the two failures look identical to users but need different fixes.
