Free Domain Expiry Checker: Check Any Domain's Expiration Date

What is a domain expiry check?

Every domain name has a registration period, typically 1 to 10 years. When that period ends, the domain expires and can be lost. A domain expiry check queries the authoritative registration database (RDAP) to show you exactly when your domain will expire, its current status, and whether anything is blocking renewal. Because it also flags renewal-blocking status codes, it doubles as a domain renew checker, not just an expiry date lookup.

Is the domain still valid?

“Valid” can mean three different things, and they often disagree. A domain can be registered, meaning a record for it exists at the registry. It can be inside its paid registration period, meaning the expiry date has not yet passed. And it can be resolving, meaning nameservers are delegated and DNS is answering. A domain in redemption is still registered but is outside its paid period. A domain carrying inactive or serverHold may be fully paid up and still not resolve. This checker answers the first two questions: it reads the registry record, so it tells you whether the domain is registered and when its paid period ends. It lists the nameservers the registry holds, but it does not query them, so it is not a test of whether the website or mail is working right now.

How to check when a domain expires

There are three practical ways to find a domain's expiry date. They do not always agree, so it helps to know which one is authoritative.

1. Use the checker above. Enter the domain and it queries the registry over RDAP, then shows the expiry date, the number of days remaining, the registrar of record, and any status codes that affect renewal. There is nothing to install and no sign-up.
2. Read your registrar's control panel.This is the fastest route if the domain is yours, but the date shown is the registrar's billing view rather than the registry record. It can differ: a registrar may render the date in local time when the registry holds a UTC timestamp, may show a renewal it has taken payment for but not yet passed to the registry, or may display its own grace-period deadline instead of the expiry date itself. When the two disagree, the registry record is the one that governs the grace, redemption and deletion deadlines.
3. Query it from the command line. Legacy WHOIS still works: whois example.com returns free-form text whose layout varies by registry, so it is awkward to parse reliably. RDAP is the structured replacement, and curl -L https://rdap.org/domain/example.com redirects to the right registry server and returns JSON. The expiry date is the event with an action of expiration.

Understanding Domain Status Codes

Domain status codes (also called EPP status codes) indicate the current state and restrictions on a domain. Understanding these codes is critical for maintaining domain security:

Domain redemption period and what each status code means

Those codes are not arbitrary. Most of them appear at a predictable point in the months after an expiry date, so the code a lookup returns tells you roughly how much time is left. For a typical gTLD such as .com, the lifecycle runs as follows.

• Day 0. The expiry date passes. Some registrars stop the domain resolving that day; others leave it up through the grace period.
• Days 1 to 30, registry maximum 45. The registrar grace period. You can normally still renew at the standard price, and this is where autoRenewPeriod usually shows up.
• From roughly day 26. Some registrars begin auctioning expiring names well before they are actually deleted.
• Around days 30 to 60. redemptionPeriod. The registrar has deleted the domain and it stops resolving, but it can still be restored for a fee for about 30 days.
• The final five days. pendingDelete. Recovery is no longer possible, and the name is released roughly 70 to 80 days after expiry.
• .uk domains run to a different clock. Nominet keeps the domain renewable at the standard price for 90 days, sends a suspension warning at day 23, suspends it at day 30, and drops it at day 95.

Why Domain Expiry Monitoring Matters

• Prevent service outages: An expired domain means your website, email, and all services go offline instantly.
• Avoid domain hijacking: Expired domains can be registered by anyone, including bad actors who use them for phishing.
• Detect renewal blocks: Status codes like serverRenewProhibited can prevent automatic renewal and need immediate action.
• Protect brand reputation: Losing a domain damages customer trust and SEO rankings that took years to build.
• Manage portfolios: Organisations with multiple domains need a single view of all upcoming renewals.

What is RDAP?

RDAP (Registration Data Access Protocol) is the modern, ICANN-mandated replacement for WHOIS. Unlike legacy WHOIS which returns unstructured text, RDAP returns structured JSON over HTTPS, providing reliable and standardised domain registration data. Our tool uses RDAP exclusively for the most accurate results.

Domain expiry monitoring: tracking renewals across a portfolio

Checking one domain is easy. Tracking fifty is a different problem, and the failure is rarely that nobody knew the date. It is that the reminder went to a mailbox nobody reads any more.

Auto-renew is not a guarantee. Most registrars switch it on by default and charge a saved card shortly before expiry, but it fails quietly when the card has expired, the billing contact has left, or the account email is out of date. Nothing bounces back to you. The registry-side evidence that a renewal actually happened is the autoRenewPeriod status, not a toggle in a control panel.

Treat the two renewal holds differently. clientRenewProhibited is usually routine. Registrars commonly apply it immediately after a successful renewal as a protective lock, so on its own it is not a reason to act; it matters only if the domain later fails to renew on schedule. serverRenewProhibited is the serious one, because the registry has blocked renewal and your registrar cannot clear it.

Use more than one threshold.A single reminder is a single point of failure. Checking at 90, 30 and 7 days gives you a planning warning, a chasing warning and a last call, which matters when a renewal needs a purchase order or a client's approval. Ninety days is also the buffer the Security Grade expects at Level 4.

MSPs have an extra problem.The domain usually belongs to the client, not to you. You may not be the registrant, may not hold the registrar login, and will not receive the registrar's expiry notices, yet you are the one who gets called when mail stops arriving. Reading the registry record directly is the only view of a client portfolio that does not depend on having an account with every registrar involved.
