Free Domain Age & Registration Checker
Look up registration date, age, expiry, registrar, security-lock status, and DNSSEC for any domain across all TLDs - one at a time or up to 20 in bulk, straight from your browser.
Why domain age and registration data matter
A domain's history is useful in several situations SEOs and business owners face regularly. When you are buying an expired or aftermarket domain, its registration date tells you whether it has real history or was registered yesterday. When you are doing competitive research, seeing when a rival registered their domain and who their registrar is adds context. And for your own domains, checking the expiry date and security-lock status prevents the worst kind of unforced error - letting a domain lapse or leaving it open to an unauthorized transfer. This tool pulls all of that from RDAP, the modern structured replacement for WHOIS, which every major registry now supports.
What the checker shows
For any domain you get the registration date and calculated age, the expiry date with days remaining (flagged in red when it is close), the registrar, the last-changed date, the full set of EPP status codes translated into plain English, the nameservers, and whether DNSSEC is enabled. The status codes are the part most tools show but never explain - "clientTransferProhibited" sounds cryptic but simply means your registrar has locked the domain against transfers, which is a good anti-theft setting. We spell each one out so you know whether a status is protecting you or warning you.
Bulk lookups for portfolios and prospecting
Switch to bulk mode to paste up to 20 domains and get a sortable table of age, expiry, registrar, and DNSSEC for all of them at once, exportable to CSV. It is built for the real jobs this data supports: auditing a portfolio of domains for upcoming expirations, vetting a list of potential acquisitions, or profiling a set of competitors. Because RDAP servers send the right CORS headers, every lookup happens directly between your browser and the registry - we never proxy, log, or store the domains you check.
Frequently Asked Questions
Google has repeatedly said domain age itself is not a direct ranking factor - a ten-year-old domain has no automatic advantage over a new one. What actually helps is the history that tends to accumulate over time: backlinks, brand signals, and indexed content. So an older domain with a real history can be more valuable, but it is the history, not the age number, that matters. Age is most useful for due diligence when buying a domain, not as an SEO metric to chase.
RDAP (Registration Data Access Protocol) is the modern, standardized successor to WHOIS. It returns structured JSON instead of inconsistent free text, supports secure access and internationalization, and is now mandated by ICANN for generic TLDs. Practically, it means reliable, machine-readable registration data - which is why this tool can run entirely in your browser where a classic WHOIS lookup could not.
A few reasons: some country-code TLDs (ccTLDs) run their own registration systems and do not expose public RDAP, some registries rate-limit or restrict browser access, and some data is redacted for privacy under GDPR (registrant names are commonly hidden, though dates, registrar, and status usually remain visible). If a lookup fails, the TLD likely lacks open RDAP rather than the domain being unregistered.
They are EPP status codes set by the registry or registrar. The "prohibited" ones (clientTransferProhibited, clientDeleteProhibited) are protective locks you want on. "pendingDelete" and "redemptionPeriod" mean a domain has expired and is on its way out - a buying opportunity or a warning depending on whose domain it is. "clientHold" or "serverHold" mean the domain will not resolve. This tool explains each code inline so you do not have to memorize them.
DNSSEC cryptographically signs your DNS records so resolvers can verify they were not tampered with in transit, protecting against certain spoofing and cache-poisoning attacks. It is a security best practice, especially for domains handling email, payments, or sensitive logins. Not having it is common and not an emergency, but enabling it (through your registrar or DNS provider) is a worthwhile hardening step.
