Domain Age Checker: See When Any Domain Was Registered

A domain age checker tells you when a domain was registered, how old it is to the day, when it expires and who manages it. The tool below reads that data live from the official registry of each extension, so you see the same record the registry holds right now, not a cached copy.

Use it to vet a domain before you buy it, to see how long competitors have held their names, or to check when your own domain expires.

How to use the domain age checker

Type a domain and press Check age. You can paste it however you have it:

• a plain domain, like example.com
• a full URL, like https://www.example.com/page: the checker keeps only the domain
• an email address, like name@example.com: it checks the part after the @
• a subdomain, like blog.example.com: subdomains aren’t registered on their own, so the checker shows the domain they belong to

To compare competitors, enter up to 5 domains separated by commas. The checker lists them from oldest to newest, with a bar that shows how their ages compare, and you can open each one for its full record.

What each result means

Age and registration date. The registration date is when the current registration began. The checker counts the exact age in years, months and days from that date, in UTC.

Expiration date. The date the current registration period ends. Domains with auto-renew turned on are renewed automatically before this date, so a near expiration date isn’t a problem by itself. If the date is less than 30 days away, the checker flags it.

Registrar. The company the domain is registered through, with its IANA ID when the registry publishes it. Some country registries, like Registro.br, don’t list a registrar.

Status codes. These are the flags the registry keeps on the domain. The most common ones:

Nameservers and DNSSEC. The servers that answer DNS queries for the domain, and whether the delegation is signed with DNSSEC.

The checker doesn’t show who owns the domain. Since GDPR, registries and registrars hide the owner’s personal details in most cases, and a domain’s age doesn’t depend on them.

Why some domains show no registration date

The checker reads RDAP, the Registration Data Access Protocol. For generic extensions like .com, .net, .org and the newer ones like .dev or .app, RDAP is mandatory: since January 28, 2025, ICANN treats it as the definitive source of registration data, replacing WHOIS.

Country extensions follow their own rules. Many offer RDAP, like .uk, .br and .fr, but when we checked the IANA list of RDAP services in October 2026, .de, .io, .eu and .co weren’t on it. For those, the checker points you to the registry’s own lookup page. Some country registries don’t publish the registration date at all, in WHOIS or anywhere else.

If the checker says a domain isn’t registered, it either was never registered or it was deleted. A domain registered in the last few minutes can also take a moment to show up.

Does domain age matter for SEO?

Not on its own. Asked whether domain age affects rankings, Google’s John Mueller answered: “No, domain age helps nothing” (Search Engine Journal).

The confusion comes from correlation. A domain that has hosted the same useful site for 15 years usually has 15 years of links, content and people searching for its name, and those are what help it rank. Register a domain today, leave it empty for 15 years, and it will be old without any of that.

So use domain age as a clue about history, not as a ranking signal. An old domain is worth more only if what happened on it was good.

Checking an aged or expired domain before you buy it

Aged domains are sold at a premium on the promise of SEO value. Before you pay for one, check what the age is actually made of:

1. Compare the registration date with the oldest snapshot on the Wayback Machine. The checker links to it. If the site existed long before the current registration date, the domain was deleted and registered again, and its age restarted. Any links it has point to a site from a previous owner.
2. Look at what the site was. Open a few snapshots from different years. A domain that hosted spam, adult content, pirated software or a site in another language brings that history with it.
3. Search Google for site: and the domain. The checker links to this search too. An old domain with years of content and no indexed pages can be a sign of trouble, so find out why.
4. Review its backlinks in an SEO tool like Ahrefs, Semrush or Moz. Many links with spammy anchor text are a warning.
5. Check domain blocklists, like Spamhaus, if you plan to send email from it.
6. Read the status codes. A domain in redemption or pending delete can’t be bought from the owner anymore; it can only be restored by them or caught when it’s released.
7. Plan for the transfer lock. Under ICANN rules for generic domains, a registrar can refuse to transfer a domain to another registrar within 60 days of its registration or of a previous transfer. ICANN has been revising these rules, so confirm the current ones with your registrar.

Before you send email from a domain you bought, check which DNS records came with it using the DNS TXT lookup, and replace the old SPF and DMARC records with your own.

Using domain age to research competitors

Enter your domain and up to four competitors, separated by commas. The comparison shows how long each one has held its name and when each expires. To see where each competitor is hosted and who runs its email, run the domain through our hosting checker.

Read it for what it is. An older competitor has had more time to build links and brand recognition, which helps explain why it ranks, but its age isn’t the reason. And if a competitor’s domain expires in a few days, it’s most likely set to auto-renew, so don’t count on it becoming available.

What happens when a domain expires

For .com and most generic extensions, an expired domain goes through these stages:

1. Grace period. The registrar keeps the domain for a period after expiration, and the owner can renew it at the normal price. The length depends on the registrar. The website and email often stop working, because many registrars put the domain on hold.
2. Redemption period. If it isn’t renewed, the registrar deletes it, and the registry keeps it for about 30 days. The owner can still restore it, usually for a restore fee on top of the renewal.
3. Pending delete. After redemption, the domain stays locked for about 5 days and is then released. Anyone can register it.

Visitors to a domain on hold get errors like DNS_PROBE_FINISHED_NXDOMAIN, and email sent to it bounces. To avoid all of this, turn on auto-renew and keep the payment method at your registrar up to date. If you’re choosing where to register, see what actually matters in a registrar.

Choosing a domain for a new project

A new domain isn’t a handicap. Search engines rank pages on what they offer, and a brand-new domain with a good site can outrank an old one with a weak site. Paying a premium for age alone rarely makes sense.

Focus on a name that’s short, easy to spell and clearly yours. Our guide on how to choose a domain name covers the details, and if you’re new to the subject, start with what a domain name is. When you have a name in mind, check if it’s available at Copahost.

Frequently asked questions

How do I check the age of a domain?
Enter the domain in the checker at the top of this page. It reads the registration date straight from the registry and shows the exact age in years, months and days, along with the expiration date, registrar and status. For up to 5 domains at once, separate them with commas. You can also use ICANN Lookup for generic domains, or run whois example.com in a terminal and look for the Creation Date.

How can I find out when a domain was registered?
Look for the registration event in the domain’s RDAP record, or the Creation Date in WHOIS. The checker at the top of this page shows it as the registration date. That date is when the current registration began: if the domain was ever deleted and registered again, it shows the newer date.

Does domain age affect SEO?
Not on its own. Google’s John Mueller has said that domain age helps nothing for rankings. Older domains often rank well because of what they built over the years, like links, content and a known brand, not because of the date itself. A domain is worth only as much as its history.

Does a domain’s age reset when it’s transferred or sold?
No. Moving a domain to another registrar or changing its owner keeps the original registration date. The date only restarts when the domain expires, is deleted and is registered again, which is why an old site can show a recent registration date.

Why can’t I see the registration date of some domains?
Because the checker reads RDAP, and not every country extension offers it. In October 2026, .de, .io, .eu and .co weren’t on the IANA list of RDAP services, so the checker links to each registry’s own lookup instead. Some registries don’t publish the registration date at all. Subdomains like blog.example.com have no registration of their own, so the checker shows the main domain.

Can I see who owns a domain?
Usually not. Since GDPR, registries and registrars hide the owner’s personal details in most cases, and the checker doesn’t show them. To reach the owner, use the contact form or the anonymized email address the registrar provides, or contact the registrar’s abuse team if the domain is being misused.

What is the difference between WHOIS and RDAP?
Both return a domain’s registration data. WHOIS sends plain text in a format that varies by registry, while RDAP returns structured data over HTTPS, with standard fields and dates. Since January 28, 2025, RDAP is the official source of registration data for generic domains like .com and .org.

What is a transfer lock?
It’s a status, client transfer prohibited, that stops the domain from moving to another registrar until the owner removes it. It’s the normal setting for a domain in use and protects against hijacking. Domains that are also locked at the registry show server update, delete and transfer prohibited.

What happens when a domain expires?
The website and email often stop working. The registrar keeps the domain for a grace period, when the owner can still renew it at the normal price. After that, the domain enters a redemption period of about 30 days, when it can be restored for a fee, and then about 5 days of pending delete before anyone can register it. Turning on auto-renew avoids all of this.

Is it worth buying an aged domain?
Only if its history is clean and fits your project. Check whether it was deleted and registered again, what the Wayback Machine shows it hosted, whether Google still indexes it and what its backlinks look like. Paying extra for the age alone rarely makes sense, because age by itself doesn’t help rankings.

How long can a domain be registered for?
Generic domains like .com can be registered or renewed for 1 to 10 years at a time. Country extensions set their own limits. A longer registration doesn’t make the domain older, but it reduces the risk of losing it to a missed renewal.

Conclusion

Domain age is a fact about a registration, not a score. The checker gives you that fact straight from the registry: when the current registration began, when it ends, who manages the domain and which locks protect it.

What the date can’t tell you is what happened on the domain. Before you buy an aged domain or judge a competitor by its age, look at its history on the Wayback Machine, its backlinks and its indexed pages. For your own domain, the numbers that matter are simpler: an expiration date far enough away, auto-renew turned on and a transfer lock in place.
