Every domain name has an expiration date, and letting one lapse can cost you your website, your email, and years of SEO authority. Checking it takes under a minute.

The fastest method is a WHOIS lookup: it shows the creation date, expiry date, and registrar for any public domain. Most registrars also show the expiry inside your account dashboard if you own the domain.

If a domain expires, it typically enters a 30-day grace period where only the owner can renew, then a redemption phase with steep fees, then it drops and anyone can register it. Expired-domain hunters watch this cycle closely.

Set calendar reminders 60 and 30 days before expiry, enable auto-renew at your registrar, and keep your contact email current — most renewal failures happen because the reminder went to a dead inbox.
