Domain Expiry Checker

Enter any domain name to check its expiration date, days remaining, registrar, and current status.

Features

Expiry Date & Days Remaining

Get the exact expiration date and days remaining for any domain. Colour-coded status indicators show healthy, warning, critical, and expired states at a glance.

Domain Health Summary

Instantly assess domain health with a clear pass/fail summary. Know whether your domain is secure, expiring soon, or already expired with actionable recommendations.

WHOIS Data Lookup

Fetches complete WHOIS information including registrar, creation/update/expiration dates, name servers, and domain status codes - all via a free public API.

Registrar Lock & Auto-Renew

Check whether registrar lock is enabled (protecting against unauthorised transfers) and whether auto-renew is active, so you never accidentally lose your domain.

Common Use Cases

Domain Portfolio Management

Easily check expiration dates across your domain portfolio. Identify domains that need renewal before they expire, preventing accidental loss of valuable web properties.

Domain Purchase Due Diligence

Before buying a domain on the aftermarket, check its expiry status and registrar lock. Avoid domains that are about to expire, in redemption, or have transfer restrictions.

Business Website Management

Ensure your business website domains never expire unexpectedly, which could take down your site, email, and online presence. Set up regular checks as part of your maintenance routine.

Client Domain Audits

Audit client domains to verify they are properly registered, locked against unauthorised transfers, and set up with auto-renewal. Provide clients with expiration reports and recommendations.

SSL Certificate Renewal Planning

Coordinate domain expiry with SSL/TLS certificate renewal schedules. Many certificate authorities require domain validation during issuance, which depends on active domain registration.

DevOps & Infrastructure Monitoring

Integrate domain expiry checks into your infrastructure monitoring routine. Catching expiring domains early prevents production outages and emergency domain renewals at premium prices.

About Domain Expiry Checking

How Domain Expiration Works

When you register a domain name, you purchase the right to use it for a specific period - typically 1 to 10 years. As the expiration date approaches, registrars send renewal reminders. If the domain is not renewed by the expiration date, it enters a grace period (usually 30-45 days) where you can still renew at the standard rate. After that, it enters the redemption period where renewal is possible but with additional fees. Finally, the domain is released and becomes available for anyone to register.

Why Registrar Lock Matters

Registrar lock (also called transfer lock) is a security feature that prevents unauthorised domain transfers. When enabled, the registrar blocks any transfer requests for the domain. This is a critical security measure because domain hijacking - where attackers steal a domain by transferring it to another registrar - can cause devastating damage to your online presence. Always keep registrar lock enabled unless you are actively transferring a domain.

Auto-Renew vs Manual Renewal

Auto-renew automatically charges your payment method and renews the domain before it expires. This is the safest option for critical domains. Manual renewal requires you to take action - if you forget, the domain may expire. Some registrars send multiple reminders starting 30-60 days before expiration. However, if your payment method on file fails or expires, auto-renew may not process, so it's important to verify that auto-renew is actually enabled and your payment details are current.

What This Tool Checks

The Domain Expiry Checker queries the public WHOIS database via a free API to retrieve the current registration status of a domain. It displays the expiration date, calculates days remaining, and parses domain status codes to determine registrar lock status and auto-renew configuration. Note that WHOIS data is provided by registrars and may sometimes be incomplete or delayed. Some domains with privacy protection enabled may show limited information.
