Domain Age Checker
Find out when any domain was first registered. See creation date, expiry date, last updated, registrar, and exact age in years, months, and days.
All Network and Web ToolsEnter a domain to see exactly how old it is, when it expires, and who registered it.
Why age is a trust signal. Registering a domain costs money and leaves a permanent public record. Scam and phishing operations burn through domains quickly, so most are only days or weeks old when they reach you. A domain registered ten years ago is not automatically safe, but it is very unlikely to be disposable.
Age is not the same as site age. Domains get bought and sold. A fifteen year old domain may have been a completely different business until last month, and expired-domain buyers rely on exactly that confusion. Check the last changed date alongside the registration date.
Some registries publish less. Certain country code registries withhold registration dates entirely. Where that happens you will see the other details rather than an error.
How the domain age checker pulls a real registration date without an API key
Domain age is not stored anywhere on the domain itself. It lives in registry records held by the organisation that manages each top level domain, and the only standard way to ask for it is a lookup protocol, not a web page you can scrape. This tool queries that protocol directly from your browser using a public relay, and does the year, month, day arithmetic on whatever registration date comes back.
RDAP, and why it replaced plain WHOIS
The classic WHOIS protocol, specified in RFC 3912, returns free form text over a raw TCP socket on port 43. That is not something a browser can open at all, since browsers only speak HTTP, HTTPS, and a handful of other whitelisted schemes. RDAP, the Registration Data Access Protocol defined across RFC 7480 through 7484, was built specifically to fix this by returning structured JSON over ordinary HTTPS, which a browser can fetch like any other API.
https:// prefix and any www. subdomain, and checked for a dot to confirm it looks like a real domain with a top level domain attached.
https://rdap.org/domain/{domain}. rdap.org is ICANN’s IANA backed bootstrap service. It looks at the top level domain, works out which registry actually holds the authoritative record, forwards the request there, and hands back the JSON response with the CORS headers needed for a browser to read it.
events array rather than fixed field names. The tool scans it for an event whose eventAction equals registration for the creation date, expiration for the expiry date, and last changed for the most recent update.
Nothing about your query is stored server side by this site. The domain name you type is sent straight to rdap.org over HTTPS, which is a third party public infrastructure service, and its response is rendered in your browser. If you want a fully private lookup with no third party involved at all, you would need to run your own RDAP client against ICANN’s registry servers directly, which is well beyond what a browser sandbox permits.
What the expiry bar actually measures
| Field | Source | Notes |
|---|---|---|
| Registered | registration event | Original creation date at the registry, not the first WHOIS record ever seen |
| Expires | expiration event | Current renewal deadline, moves forward each time the domain is renewed |
| Last updated | last changed event | Any registry side change, including a nameserver swap, not just ownership |
| Registrar | vCard fn field on the registrar entity | The company the domain is registered through, not the hosting provider |
| Expiry bar percent | (now minus registration) / (expiry minus registration) | How far through the current registration term the domain currently sits |
.com, .net, and .org have supported it for years, some country code domains such as .de have limited or no public RDAP data, and this lookup will fail or come back incomplete for them. That is a registry limitation, not a bug in this tool.Why domain age matters at all
SEO signal, weakly
Search engines have said domain age by itself is not a significant ranking factor. What correlates with rankings is accumulated backlinks and content history, which older domains simply have had more time to build.
Trust and fraud screening
Freshly registered domains are disproportionately used in phishing and scam campaigns because attackers burn through domains quickly. Security tools frequently flag domains under 30 days old for extra scrutiny.
Domain investment research
Buyers and sellers in the domain aftermarket use age as one input among many, alongside backlink profile and brandability, when pricing an existing domain.
Expiry monitoring
The days remaining figure is a quick way to check whether a domain you are watching, or one a client owns, is coming up for renewal or has recently lapsed into a redemption period.
- RFC 3912 is the original WHOIS protocol specification, port 43, plain text, no standard field format.
- RFC 7482 defines the RDAP query format this tool relies on.
- ICANN’s RDAP overview explains why the industry moved away from raw WHOIS.
- rdap.org is the bootstrap relay this tool queries.
What domain age really tells you
Vetting a new supplier or vendor’s web presence before signing a contract, screening a domain that just showed up in your inbox as a sender before treating any link as trustworthy, checking how long a competitor’s site has actually existed, due diligence before buying an aftermarket domain, and confirming a domain’s renewal window before it lapses and someone else grabs it.
Common Questions
Questions About the Domain Age Checker
Older domains tend to have more accumulated backlinks, indexed pages, and trust signals. Google has said domain age alone is not a significant ranking factor, but the content and links built over years are. A domain registered in 1998 is not automatically better than one from 2020 — but it has had more time to build authority.
RDAP (Registration Data Access Protocol) is the modern successor to WHOIS. Unlike WHOIS which returns plain text in inconsistent formats, RDAP returns structured JSON, supports HTTPS, and handles internationalized domain names properly. ICANN mandated all registries support RDAP. This tool uses RDAP instead of WHOIS for cleaner, more reliable data.
Some country-code TLD registries do not publish registration dates in RDAP, or have privacy policies that redact this information. Newly registered domains may take hours to appear in RDAP. Some smaller registries have not fully implemented RDAP yet and the data may be incomplete.
Enter any domain name in this tool. Domain registration data is public information available to anyone via RDAP and WHOIS. Registrant contact information may be redacted under GDPR and similar privacy regulations, but registration and expiry dates remain publicly accessible.
The expiry bar shows the proportion of the current registration term that has elapsed. Green means plenty of time remains, yellow means the domain is approaching renewal, red means the domain is close to expiry and the owner should renew soon to avoid losing it.
